Five species from China are described and illustrated. Among which, three species, A. longicoxilla, A. reticoxilla and A. campylura are new to science, two species are first records from China, A key to the five species is provided. All specimens examined are deposited in Biological Control Research Institute, Fujian Agriculture and Forestry University, Fuzhou, China.展开更多

Diagnostic characters for the new species are given in comparison with the apparently closely related P. onomarchicidum. Two other mymarid species are also newly recognized from China： Mymar africanum Annecke and Anagroidea marina Triapitsyn et Berezovskiy.展开更多

We have assessed the potential effects of DKC 6451 YG （MON810） maize on canopy NTAs in a farm-scale study performed in Central Spain during 3 years. The study focused on hemipteran herbivores （leafhoppers and planthoppers） and hymenopteran parasitic wasps （mymarids） collected by yellow sticky traps, which accounted for 72% of the total number of insects studied. The dynamics and abundance of these groups varied among years, but no significant differences were found between Bt and non-Bt maize, indicating that Bt maize had no negative effect on these taxa. Nonetheless, the CrylAb toxin was detected in 2 different arthropods collected from Bt maize foliage, the cicadellids Zyginidia scutellaris and Empoasca spp. A retrospective power analysis on the arthropod abundance data for our field trials has determined that Z. scutellaris and the family My- maridae have high capacity to detect differences between the Bt maize and its isogenic counterpart. The use of these canopy NTAs as surrogates for assessing environmental impacts of Bt maize is discussed.展开更多
