利用性信息素诱捕器监测木槿曼粉虱

Survey method by using the sex pheromone traps in Maconellicoccus hirsutus

木槿曼粉蚧(Maconellicoccus hirsutus)是一种多食性刺吸害虫,其寄主范围很广,包括林木、果树、蔬菜及粮食等农作物;该虫现分布于亚洲热带地区、中东、非洲、澳大利亚中美州和美国南部。我们从美国农业部引进了木槿曼粉蚧性信息素及其诱捕器,对上海、广州、广西和海口的港区进行了诱捕试验,结果没有诱到木槿曼粉蚧。说明这些设置诱捕器的具体地点尚没有被入侵。根据资料,本文还介绍了该虫的生活史。

Maconellicoccus hirsutus is a sap - sucking insect and also a highly polyphagous bug. It can attack forest trees, fruit trees, vegetables and crops. It distributes now in Asian tropical areas, middle - east, Africa, Australia, Middle America and the Southern US. However, there is no data on its distribution in the main land of our country. We introduced its sex pheromones and the trapping technique and conducted a survey by using the tech- nique in Shanghai, Guangzhou, Nanning and Haikou. Results showed that there was not its distribution in the above areas. To get its detailed distribution data, a detailed survey program by using the technique is needed.
