Sem investigation of chemical sensilla of antennae of Coccinella septempunctata and Leis axyridis

七星瓢虫和异色瓢虫触角上分布粗大的毛状感器和短小的锥状感器。毛状感器分布于各个亚节 ,锥状感器主要密布于鞭节的末节端部。化感器的数量大小顺序 :七星瓢虫 >异色瓢虫显明变种 >

There were crassitude sensillum trichodeum and smallish sensillum basiconicum on antennae of Coccinella septempunctata and Leis axyridis . sensillum trichodeum distributed on the every subsegment, and sensillum basiconicum densely covered the end sub segment of flagellum. The number of sensilla followed the order: Coccinella septempunctata 's > Leis axyridis (Pallas) var. spectabilis 's > L.axyridis (Pallas) ab. bimaculata 's and L.axyridis (Pallas) var. novemdecimpunctata 's.
