摘要/Abstract

摘要： 利用“Y”型嗅觉仪测定了褐飞虱对同类昆虫遭遇草间小黑蛛捕食时产生的挥发性物质的行为反应，目的验证褐飞虱在遭遇危险时是否产生向同类报警的化学信号。结果表明，褐飞虱若虫对草间小黑蛛释放的挥发性物质无逃避反应，对同类昆虫遭遇草间小黑蛛捕食时释放的挥发性物质的反应因虫龄而异，其中2～3龄若虫有极显著的逃避反应，1龄和4～5龄若虫无明显反应。该结果说明褐飞虱2～3龄若虫在遭遇天敌捕食时会释放挥发性化学物质，产生报警行为，向同类昆虫发出危险警示信号，但褐飞虱1龄或4～5龄若虫的报警行为不明显，其原因可能是褐飞虱4～5龄若虫不易被草间小黑蛛捕食或者褐飞虱1龄若虫虽易被捕食，但其产生的报警信号不明显。

Abstract: In order to verify whether the alarm signal was released when the insect attacked by its natural enemies， Erigonidium graminicolum， behavioral responses of the brown planthopper （BPH）， Nilaparvata lugens Stl， to the volatile substance released by the same kind of insects in danger were studied with Y-tube olfactometer. The results showed that BPH nymphs had no response to the volatile chemicals of E. graminicolum released， but escaped when received the chemicals released by the same kind of insects attacked by E. graminicolum. However, such responses varied in different instar nymphs. The 2nd to 3rd instar nymphs of BPH responded strongly to the volatile released by the same kind of insects， while no obvious response was made by the 1st， 4th to 5th instar nymphs of BPH to the volatile. The results above indicated that 2nd to 3rd nymphs of BPH in dangerous environment could release volatile substances and give a dangerous alarm signal to the same kind of insects， but 1st， 4th to 5th nymphs had not obvious alarm behavior. There might be reasons that mature nymphs of BPH could not be easily predated by E. graminicolum， or the youngest nymphs could not release a strong alarm signal while attacked by the natural enemy．
