The current study evaluated the interactive impacts of water temperature and feeding rate on digestive enzymes, intestine histology, growth and stress-related genes, and cultivable intestinal microbiota of Asian seabass (Lates calcarifer). For this purpose, 180 fish (85.0±3.0 g) were reared at three different temperatures (20, 27, and 33 °C) and two feeding rates (apparent satiation and 2.5% of biomass) with three replications for 6 weeks. The results revealed no significant differences among different treatments regarding the activity of digestive enzymes (P˃0.05) of fish reared under different temperatures and feeding rates. The length, width, and thickness of intestinal villi were unaffected by different temperatures and feeding rates (P˃0.05). In addition, no variations were found in the total aerobic bacterial count of fish gut from different experimental groups (P˃0.05). At the molecular level, IGF-I and HSP70 coding genes were found to be highly expressed in experimental treatments (P<0.05). To conclude, present results showed that temperatures between 27 to 33 °C are more optimal for Asian seabass, and the different temperatures and feeding rates do not affect digestive enzymes, intestine histology, and gut microbiota after 6 weeks. Further molecular research is needed to unravel the complex impact and mechanisms of feeding rate and different rearing temperature on fish physiology.

Cabbage leaf miner Scaptomyza flava (Fallen) (l)iptera: Drosophilidae) is a native and oligophagous leaf miner insect on cruciferous plants (Brassicaceae). It occurs in many parts of the world and throughout Khuzestan. The relationship between feeding and ovipositional preferences of insect, and host plant suitability on seven host plant species (cauliflower Brassica oleracea var. botryds, green cabbage B. oleracea var. capitata, hedge mustard Sisymbrium officinale, brussels sprout B. oleracea var. germmifers, turnip Brassica rapa, cucumber Cucumis mtivits, wheat Triticum aestivum and rice Oryza saliva) was evaluated. Ovipositional preference of 5. flava was determined by measuring feeding punctures and egg density after ndult female flies were given a simultaneous choice and non-choice of all host plants for feeding and oviposition. Studies were performed under greenhouse conditions. The experimental design was a randomized complete block one with 8 treatments and 5 replications of each treatment. S. jlava showed distinct hierarchical ordering in its ovipositional preference, with turnip, green cabbage, and hedge mustard being preferred over all others. Approximately 1.05 and 5.8 times more eggs were deposited on green cabbage than on turnip and cauliflower respectively. When the percentage of punctures with eggs was calculated for each species, cauliflower had by far the highest value at 10% and 19.7% in choice and non-choice tests respectively. For all other species on which eggs were laid it was less than half this. In non-choice tests, females laid more eggs on green cabbage and turnip than other brassicas.

The probiotic effects of Saccharomyces cerevisiae and Aspergillus niger on the feeding efficiency, body composition, ammonia excretion, blood serum enzymes and the intestinal microbiota of juvenile beluga, Huso huso was investigated. The fish (31.8±2.81g) were randomly allocated into 12 oval tanks at a density of 30 individuals per tank with three replicates for each treatment,. The fish were fed either a basal diet (as control) or the diet supplemented with S. cerevisiae and A. niger (2×10⁶, 4×10⁶ and 6×10⁶ cells g^-1) for 8 weeks. The results indicated that the probiotic supplemented diet at 6×10⁶ (cells g^-1) significantly improved FCR and other nutritional indicators compared to the control treatment (p<0.05). Significant improvements (p<0.05) were also observed in ammonia excretion and blood serum enzymes between treatments. Total viable fungus and Lactobacillus spp. count were significantly improved in treatment compared to control (p<0.05). These results indicated that S. cerevisiae and A. niger improved feeding performance and blood serum enzymes of beluga.

The eggs and larvae of the Indian meal moth, Plodia interpunctella (Hübner), are widely used in mass rearing of parasitoids and predators. Feeding indices and some biological parameters of P. interpunctella were studied on bran of different wheat cultivars ('Back-cross Roshan', 'Khooshe Pishgam', 'Khoshki line 9', 'Arg', 'Alvand', 'Pishtaz', 'WS-89-2', 'Sepahan' and 'Bam') when incorporated into artificial diets under laboratory conditions (25 ± 1 ºC, 65 ± 5% R.H., and a 16:8 h light-dark photoperiod). The efficiency of conversion of ingested food was highest on 'Back-cross Roshan' (98.79 ± 8.48%) and lowest on 'Pishtaz' (64.56 ± 9.66%). The highest and lowest percentage of mortality of P. interpunctella larvae were on 'Pishtaz' (56%) and 'Back cross Roshan' (12%). Our results showed that larval growth index was highest on 'Khoshki line 9' (5.81) and lowest on 'Pishtaz' (3.33). Moreover, the highest daily and total fecundity were detected in moths that were reared on 'Back-cross Roshan' (37.6 ± 0.93 and 177.3 ± 1.61 eggs, respectively). The results demonstrated that, among different wheat cultivars tested, 'Back-cross Roshan' was the most suitable cultivar for P. interpunctella rearing in order to optimize the mass production of natural enemies.

The effect of a probiotic containing five species of bacilli at four levels of 0 (control), 1×10⁶CFU/ml (T₁), 1×10⁷ CFU/ml (T ₂) and 1×10⁸CFU/ml (T ₃) per 100g of feed on the growth performances, resistance and survival of rainbow trout fry, Oncorhynchus mykiss (463±32 mg) were compared in a  60-days feeding trial. Growth parameters, such as ADG, SGR, RGR and TGC, were significantly enhanced (p<0.05) by the probiotic at all levels, and the performance in T₂ was significantly better than T₁. The fish under the probiotic treatments also showed higher resistance (p<0.05) to such Environmental stresses as alkaline pH, heat and ammonia (p<0.05). No significant difference in tolerance to acidic pH stress was observed between the control and treatments. In conclusion, the probiotic bacillus highly increased the growth performances, feeding efficiency, resistance and survival in rainbow trout fry.

In a completely randomized design, the effects of two probiotic bacteria, Bifidobacterium animalis and B. lactis at four concentrations of 0 (control), 1×10⁹ (T1), 2×10⁹ (T2) and 3×10⁹ (T3) CFU 100g^-1 on nutritional parameters of rainbow trout fry (0.538 ± 0.197 g body weight) were compared for 60 days, with each treatment carried in three replications. A significant difference was observed between treatments and the control in protein and lipid gain and also body composition (p<0.05). Despite a significant difference of metabolic growth rate in T1 and T2 with T3 and the control, no significant difference was observed between T3 and the control. The results demonstrated that the use of thesebacteria could improve nutritional parameters and metabolic growth rate of rainbow trout fry.

Nutritional indices of Helicoverpa armigera (Hübner) larvae, an economic insect pest of agricultural crops in the world, were studied on five corn hybrids (SC700, SC704, SC500, DC370 and SC260) when incorporated into artificial diets under laboratory conditions at 25 ± 1 °C, relative humidity of 65 ± 5% and a photoperiod of 16:8 (L: D) h. The highest values of consumption index (CI) and relative growth rate (RGR) for the fourth instars were on SC500 (37.21 ± 3.34 and 0.43 ± 0.07 mg/mg/day, respectively) and lowest values of these indices were on SC704 (21.44 ± 2.83 and 0.18 ± 0.04, respectively). Among the five corn hybrids tested, efficiency of conversion of ingested food (ECI) of fifth instars was the highest on SC260 (6.92 ± 0.5%) and the highest value of efficiency of conversion of digested food (ECD) was on SC704 (10.71 ± 3%) while the larvae fed on SC700 had the lowest values of ECI and ECD (3.57 ± 0.3 and 4.39 ± 0.4%, respectively). For the sixth instar larvae, although the lowest CI and approximate digestibility (AD) values were observed on SC260 (3.49 ± 0.17 and 53.89 ± 3.70%, respectively) the highest value of ECI and ECD was on SC260 (9.11 ± 0.6 and 16.54 ± 1.5%, respectively). For all instars (fourth to sixth instars), ECD value of H. armigera was the highest on SC260 (10.15 ± 1.08%) and lowest on SC700 (6.32 ± 0.47%). The result of this study pointed out higher nutritional performance of the larvae H. armigera reared on SC704 and SC260 and lower performance on SC700 and SC500.

Control of stored-product insect by gamma radiation could be enhanced by other possible techniques such as essential oils as effective alternatives to chemical insecticides. In this study, the efficiency of gamma radiation combined with Perovskia atriplicifolia (Benth) was verified to assess their enhanced antifeedant effect against the Tribolium castaneum (Herbst). Flour disc bioassay was employed to assess the nutritional indices, such as relative growth rate (RGR), relative consumption rate (RCR), efficiency of conversion ingested food (ECI) and feeding deterrence index (FDI). The results showed that irradiation, essential oil and combination of both of them significantly reduced RGR, RCR and ECI in treated larvae and adults. As irradiation at 100 Gy reduced RGR of the larvae and adults from 0.0884 and 0.0366 to 0.0596 and 0.0332 mg/mg/day respectively, when combined with doses of P. atriplicifolia essential oil, the reduction reached to 0.051 - 0.388 and 0.01- 0.224 mg/mg/day respectively. The reduction rates in larvae were even greater when combination of irradiation and EO treatments were used. The results showed a significant increase in the feeding deterrence due to irradiation, essential oil and specially their combination. Therefore, findings led to a conclusion that irradiation can enhance antifeedant activity of essential oils.

Feeding performance of the green oak leaf roller, Tortrix viridana (Linnaeus) was determined on three host plants including Quercus libani Oliv, Quercus infectoria Oliv, and Quercus branti Lindl, under laboratory conditions. Mean total leaf weight consumed by larvae was the highest on Q. branti (0.31 g) and the lowest on Q. libani (0.14 g).The feeding index was the highest on Q. libani while the other two host plants were not significantly different. Significant relationships were found between amount of consumed leaf tissues and resulting pupal weight, on all host plants. Larval and pupal mortality were not significantly different on host plants. Findings indicated that the feeding index could be a key factor to assess performance of T. viridana on Quercus species.

Based on the gut content analysis of 278 specimens of brown trout, Salmo trutta, in the Lar Reservoir and its basin, including streams of Delichay, Ab Sefid, Elarm, Lar and Siah Plas, the summer food habits were found to be general and depended on the abundance of preys. Considering the “index of relative importance” in all stations, the most consumed prey items in the streams were Diptera larva, Ephemeroptera and Trichoptera nymphs, while Hymenoptera constituted the main prey in the reservoir. It was found that the gender had no significant effect on the feeding habits of the adult brown trout.

The effect of dietary composition and starvation on growth and plasma metabolites in rainbow trout of 14 g average initial weight was investigated. A group of 240 trout juveniles were distributed in 12 of 150 L tanks. The experiment was performed in a 2*2 factorial design with 2 lipid levels (10 and 18%) and 2 feeding conditions (feeding and starvation) with 4 treatments each with 3 replicates. The fish were fed on diet 1 (lipid 10%, carbohydrate 29%) and diet 2 (lipid 18%, carbohydrate 19%) with the same protein level (47%) and energy. The juveniles were fed to apparent satiation for 3 weeks, followed by starving for 2 weeks and then refed for 3 weeks. The biometery and plasma biochemical parameters were analysed in the day of 21 (end of 3 weeks feeding), 35 (after 2 weeks starvation) and 60 (end of 3 weeks refeeding). Based on the result, the best growth performance in the fish occurred in diet with 10% lipid in control group (feeding group) and no compensatory growth occurred in this treatmennt after 2 weeks starvation. Moreover, the result of body composition showed the starvation and diet composition had more effect on body lipid than body protein and body lipid content decreased by starvation. The starvation and diet composition did not have any significant effect on cholesterol and triglyceride, but they induced decreasing plasma glucose level in the trout.

Many of our fundamental concepts such as time, quantity, state, change, act, cause, purpose, way of doing, modality, and even concepts of categories understood through metaphoric concepts. To show his theosophical world, mevlana mostly used metaphoric concepts. Feeding is one of the most commonly used concept in Divan e-Shams for showing all the materialistic and spiritual realms and other family words helped the poet to reflect these concepts. Life of Sofia and attention to reduce feeding, esurience, fasting and avoiding businesses and valuing the trust theory caused unconscious adoption of such metaphor for mevlana. Accordingly, the eight categories of beauty, wisdom, mystery, citation, hearing(samaa’), joy, love and light as a feed can be explained. In this paper, using the metaphor of contemporary cognitive theory to explain this metaphor will be discussed. Finally, it is clear that the notion of "Feed mysticism" the fundamental proposition of text feed a metaphorical thinking that he has released over the Divan-e Shams.

Essential oils of four aromatic plants, Artemisia monosperma Del., Callistemon viminals (Sol.ex Gaertn.) G. Don, Citrus aurantifolia (Christm.) Swingle and Cupressus macrocarpa Hartw. ex Gordon, were evaluated for their anti-nutritional, antifeedant, growth inhibitory and insecticidal activities against Sopdoptera littoralis (Boisduval) (Lepidoptera: Noctuidae). The essential oils of A. monosperma and C. aurantifolia caused the highest reduction in relative growth rate (RGR) at the tested concentrations (125, 250, 500, 1000 and 2000mg/l). The RGR values ranged between 8.63 and 3.05 mg/day for A. monosperma, and between 10.74 and 2.89 mg/day for C. aurantifolia compared with 14.89 mg/day for control after 72 h of treatment. In general, the results showed that the values of relative growth rate (RGR) decreased with increasing the concentration of the tested oils. In addition, the tested oils significantly reduced efficiency of conversion of ingested food (ECI) and efficiency of conversion of digested food (ECD) values, particularly at the higher concentrations of 500, 1000 and 2000mg/l. On the other hand, the tested oils showed antifeedant activity against the larvae of S. littoralis with A. monosperma and C. aurantifolia oils being more active than C. viminals and C. macrocarpa oils. The tested oils showed remarkable growth inhibition effect as the growth inhibition index values were increased from 37.63 to 79.80% for A. monosperma, from 21.69 to 52.12% for C. viminals, from 16.55 to 28.59% for C. aurantifolia and from 37.64 to 52.32% for C. macrocarpa when the concentration increased from 125 to 2000mg/l. Based on chitin formation ratio values, the tested essential oils induced reduction in chitin formation. A. monosperma and C. macrocarpa essential oils revealed the highest insecticidal activity on 4^th instar larvae of S. littoralis. Examination of reproductive tracts of adult females emerged from treated larvae indicated that the tested oils caused undifferentiated ovarioles.

Aims: Due to vital role of optimum feeding rate on success and profitability of an aquaculture practice, feeding rates were examined in different life stages of Beluga sturgeon.
Methods: Feeding rates were 5%, 7%, 9%, 11%, 13% and 15% in stage 1; 2%, 4%, 6%, 8%, 10% and 12% in stage 2; 1.5%, 2%, 2.5%, 3% and 3.5% in stage 3; 1.5%, 1.75%, 2%, 2.25% and 2.5% in stage 4. Farming durations of stages 1 to 4 were 10, 10, 42 and 56 days, as well as initial mean weights were 1.85, 7, 112.04 and 300.54 g, respectively.
Findings: Results showed that optimum feeding rates from growth and feeding parameters point of view were 9% and 5%, respectively, in stage 1. In stage 2 also optimum feeding rates were different from growth and feeding point of view, as they were 4% and 2%, respectively. For both aspects of growth and feeding parameters, optimum feeding rate was 2.5% of body weight in stage 3. In stage 4, the lowest food conversion rate was observed in the feeding rate of 1.5% and there were no significant differences between treatments from growth parameters point of view.
Conclusion: Growth and feeding parameters were affected with feeding rates in stages 1, 2 and 3. In stage 4, feeding rates influenced feeding parameters, but had no significant effects on growth performance.

Recently, the methods that improve essential oils (EOs) properties and make them appropriate to be applied as biorational pesticides have been regarded more precisely. The essential oils nanoformulation (EONF) is a promising strategy to develop and facilitate the applicability of the EOs in stored pest management. In this study, the toxicity, antifeedant and physiological effects of Mentha spicata L. and Mentha pulegium L. EOs and their NFs was investigated on the red flour beetle, Tribolium castaneum (Herbst). Characterization of nanocapsules using dynamic light scattering (DLS) and transmission electron microscopy (TEM) showed that the nanocapsules were spherical in shape with the average sizes of 56.91 and 98.99 nm for M. spicata and M. pulegium EONF, respectively. The encapsulation efficiency obtained was 95.47 and 86.03% for M. spicata and M. pulegium EONF, respectively. After 72 h, the LC₅₀ values of the EOs and NF of M. spicata were 18.422 and 9.279 µl/ml and 7.939 and 6.793 µl/ml for M. pulegium, respectively. The results confirmed that the feeding indices of T. castaneum were affected by the EOs and their NFs. In addition, both the EOs and EONF decreased the relative growth rate (RGR) and relative consumption rate (RCR) and had a moderate feeding deterrent activity on the adults of T. castaneum. The EOs and their NFs decreased the general esterase, acetylcholine esterase, α-amylase and general protease and increased the glutathione S-transferases activity of T. castaneum. The overall findings of this research suggest that the NF of the EOs (especially M. pulegium) can be used for an efficient control of T. castaneum.

Phonological opacity has always been the subject of much debate in generative phonology, particularly after the emergence of Optimality Theory (OT). According to Antila (2006) Opacity arises when a phonological process applies even if its conditioning environment is not met on the surface (overapplication), or conversely, fails to apply even if its conditioning environment is met on the surface (underapplication). Counterfeeding and counterbleeding interactions cause opacity. It may also be caused by a feeding interaction. Opacity is a challenge for optimality theory which denies phonological rules and intermediate levels between the underlying representation and the phonetic representation. While rule-based approaches that consider intermediate levels have no problem dealing with opacity. This research aimed at introducing opacity, arguing for the existence of Counterfeeding and counterbleeding interactions in Persian, arguing for the opacity of a feeding interaction in Persian, and finally analyzing these opaque interactions within the frameworks of classic Optimality Theory (Prince & Smolensky, 1993/ 2004) and/ or Harmonic serialism (McCarthy, 2000). In order to identify the phonological processes, the data were carefully analyzed according to various phonological environments. Then, these environments were analyzed to determine the constraints involved in each opaque interaction. In this paper, first, the existence of a counterfeeding interaction in the conversion of the underlying representation /bA# am/ to the phonetic representation [bAm] (not to *[bum]) was discussed. This opaque interaction was analyzed within classic OT using enriched positional faithfulness constraint IDENT(low)/#  which causes *[bum] to lose and [bAm] to win. Moreover, the counterbleeding interaction in the occurrence of “nasal place assimilation” between the palatal consonant /Š/ and /n/, and the consequent deletion of /Š/ (the source of assimilation) was discussed. This opaque interaction was analyzed within the framework of Harmonic Serialism by formalizing the markedness constraint Cσ*NP].  Finally, it was argued that the conversion of the underlying /-id/ to [-in] is due to the insertion of [n] between /i/ and /d/, and the consequent deletion of /d/. After arguing why this feeding interaction is considered opaque, it was analyzed within the framework of Harmonic Serialism by formalizing two markedness constraints *id_CL and*nd].
