Searching Behaviore of Adult Dastarcus helophoroides (Fairmaire) (Coleoptera: Zopheridae) for Apriona swainsoni (Hope) (Coleoptera: Cerambycidae)
摘要
Abstract
Dastarcus helophoroides (Fairmaire) is an important insect natural enemy ofApriona swainsoni (Hope), a serious wood borer of Sophorajaponica Linn., which is a city-tree of many cities in northern China. In order to unravel the mechanism underlying host searching behavior ofD. helophoroides adults, the olfactory responses of D. helophoroides adults toward host larval frass, wood and bark with host larval tunnels were investigated by using Y-tube olfactometer. Results showed that volatiles from larval frass ofA. swainsoni, wood with larval tunnels, and wood without larval tunnels but from the infested tree were significantly attractive to D. helophoroides when compared with blank air. Host larvae, bark with host larval tunnels, and wood from health tree were not attractive to D. helophoroides. D. helophoroides adults showed no significantly difference in orientation between larval frass and wood with larval tunnels in the Y-tube olfactory. These results indicate that larval frass ofA. swainsoni and wood with larval tunnels could release semiochemicals that are attractive to the natural enemy.关键词
