Abstract
The fauna of the braconid subfamilies Euphorinae, Homolobinae, Macrocentrinae and Rogadinae were studied in Kerman province. Specimens were collected using Malaise traps and sweeping net during 2013–2014. A total of 14 species and eight genera were collected and identified. Among the collected material, Aleiodes (Chelonorhogas) ruficornis (Herrich-Schaffer, 1838) is a new record for the fauna of Iran. All species are new for the fauna of Kerman province.

Abstract
Aphidiinae is one of the most important subfamilies of Braconidae, species of which play an important role in biological control of aphids (Hemiptera: Aphidoidea). In this study, the effects of humidity and temperature on the density and dispersal of different species of the subfamily Aphidiinae were investigated in three different ecological areas of Bardsir (Kerman province), located in southeast Iran. Specimens were collected by a hand net on field crops in three stations (Bardsir, Lalehzar and Negar) during March to November 2013. Altogether nine species belonging to five genera (Aphidius, Praon, Diaeretiella, Trioxys and Lysiphlebus) were recorded from these areas. The results revealed that the majority of species were found in the area with temperature between 18 to 20 °C and/ or with humidity rate of 34 to 39%, 40.1 and 50.6 percent of specimens respectively. Most of the collected members of this subfamily were found in the average temperature of 18.5 ± 1.13 °C. Trioxys complanatus Quilis, 1931 was the dominant species. According to biodiversity and ecological indices, species diversity and dispersal were different in the three stations. In conclusion, temperature and humidity have great impact on species diversity and distribution pattern of Aphidiinae.

Abstract
In this study the morphological body variation in five species of Gobiid fish from the intertidal zone of the Persian Gulf and Gulf of Oman have been investigated using 18 morphometric and also three meristic characters. According to the results, 19 of 21 morphological characters of studied species showed a significant statistical difference and among these species, the only two characters "total length" and "pre anal distance" were not statistically different. The results of linear discriminant analysis (LDA) had separated 24.95% of individuals by using morphological characters of the fish body. Data analysis by principal component analysis (PCA) showed that some of morphological characters could be more determinant in species separation in two first axis (PC1 and PC2) which occasionally are possessed in common between two studied species. On the other hand, calculating the Euclidean distance according to studied morphological characters represented that there are small differences in body shape of some species i.e. Boleophthalmus dussumieri and Scartelaos tenuis among other studied species. The results of this study revealed that studying the morphological characters in gobiid fish body shape using univariate and multivariate analysis could make a new vision in these morphological variations of fish body survival.
