白星花金龟发生与防治技术研究初报

白星花金龟,Potosia（Liocola）brevitarsis（Lewis）]是新疆维吾尔自治区昌吉地区农作物、果树及林木上发生的一种新害虫,近年来其发生和危害逐年加重,为此,笔者通过大面积多点取样调查和定点、定时观测以及建立昆虫园等方法初步摸清了其生活习性和危害的各种寄主作物,并提出了适合昌吉地区的防治措施和对策,如人工捕捉、集中诱杀、粪堆处理、拒避成虫以及药剂防治等,为控制该虫的发生和危害提供了依据.

A Study on the Occurrence of Postosia Brevitarsis Leiwis and Its Prevention & Control Technology

Potosia brevitarsis Lewis is a kind of new pest currently found on the crops, fruit trees and forest woods in Changji area, Xinjiang Ugur Autonomous Region. Its occurrence and harm is growing increasingly severe every year. The researchers adopted a series of research methods including quasirandom sampling on a large scale, multi-case observation and simulated insect gardens and learned about its morphological characteristics and the kinds of its host crops. Based on that, a tentative prevention and control framework was proposed in the paper such as artificial elimination, collective trapping and killing dunghill disposal, expelling adults and chemical prevention, etc.
