【摘要】：混腔室繭蜂(Aulacococentrum confusum)是桑樹害蟲桑螟(Diaphania pyloalis)的優(yōu)勢寄生蜂。應用掃描電子顯微鏡技術觀察混腔室繭蜂觸角感器的微觀結構,以利于對該寄生蜂的寄主搜索、求偶和取食等行為生態(tài)學及保護生物學進行研究。觀察結果表明,混腔室繭蜂雌、雄成蟲觸角上共有6種感器,分別為毛形感器、B錸hm鬃毛、板形感器、栓錐形感器、錐形感器和刺形感器,其中栓錐形感器僅分布于雌蜂觸角上,其余感器的數(shù)量、大小在雌蜂和雄蜂之間無顯著差異。與多數(shù)繭蜂科寄生蜂相比,混腔室繭蜂成蟲的觸角明顯偏長,雌、雄蜂觸角長度分別達到19.3 mm±1.9 mm、16.4 mm±3.4 mm,推測與其搜尋在桑葉上隱蔽取食的寄主桑螟有關。
[Abstract]:Aulacococentrum confusumsum is the dominant parasitoid of mulberry pest Diaphania pyloalis.The microstructures of antennae sensilla were observed by scanning electron microscopy (SEM) in order to study the behavior ecology and conservation biology of the parasitoid parasitoids such as host search, courtship and feeding.The results showed that there were 6 types of sensilla on the antennae of female and male parasitoids, which were hairy sensilla B rhenium hm mane, plate sensilla, cork cone sensilla, conical sensilla and spiny sensilla.The conical sensilla was only distributed on the antennae of female wasps, and there was no significant difference in the number and size of other sensilla between female and male wasps.Compared with most parasitoids, the antennae of adult parasitoids were longer than that of most parasitoids. The antennae length of female and male wasps were 19.3 mm 鹵1.9 mm and 16.4 mm 鹵3.4 mm, respectively, which might be related to the search for host mulberry borer, which was hidden and feeding on mulberry leaves.
