تخمین حداکثر غنای گونه‌ای زنبورهای زیرخانوادهCampopleginae (Hymenoptera: Ichneumonidae) در دشت گل محمدی دیم داراب، ایران

The subfamily Campopleginae with 2127 worldwide known species into 66 genera is one of the most diverse subfamilies of the family Ichneumonidae (Hymenoptera: Ichneumonoidea). Members of this subfamily mostly attack Lepidoptera larvae as koinobiont endoparasitoid. From biological control point of view, campoplegines have been one of the most widely investigated ichneumonids for classical biological control as well as indigenous agents. The aim of this study was to investigate and to estimate species richness of this subfamily wasps in Darab rain-fed damask rose plain (5300 hectares), Fars, Iran during 2019. In this plain, using chemical pesticides is banned and damask rose organically cultivated. For this purpose, four malaise traps were installed at the entrance, end and center of this plain from April to October. Collecting pots of each trap were emptied in biweekly intervals and the captured wasps were separated and then dried and mounted. Species identifications were made based on morphological characters using available keys and descriptions on this subfamily. The identified species were then considered as morphospecies. Maximum species richness was estimated by Chao quantitative, Chao presence-absence, 1st order jackknife, 2nd order Jackknife and bootstrap estimators. During this sampling, 743 individuals of this subfamily have been collected and sorted into 19 morphospecies. The maximum species richness of this subfamily wasps was estimated by Chao quantitative (36), Chao presence-absence (32), 1st order Jackknife (27), 2nd order Jackknife (31) and Bootstrap (24) species. High local species richness and abundancy of this subfamily indicate the potential of these parasitoid wasps in biological control of lepidopterous pests and consequently ecological maintenance of this unique organic and natural ecosystem.
