摘要
烟粉虱是设施蔬菜上的重要害虫。为探讨烟粉虱的可持续控制方法,在蔬菜试验基地,通过虫源清理、黄板诱杀、诱集剂诱杀和芹菜间作驱虫等综合措施,研究非化学措施对黄瓜烟粉虱的持续控制作用。结果表明:在烟粉虱扩散迁移阶段,虫源的距离与成虫向大棚的迁入量呈负相关,虫源虫量与迁入量呈正相关;虫源扰动对烟粉虱迁入具有促进作用;烟粉虱在扩散过程中对新寄主仍遵循就近选择的原则;对黄板的选择性明显高于黄瓜,两者之间的虫量比在7.91∶1~420.00∶1;在棚内使用黄板加引诱剂及黄板加芹菜对黄瓜上的烟粉虱均具有较好的控制作用,虫口减退率均达到90%以上。结果表明,区域生态防控是对烟粉虱进行可持续绿色控制的有效方式。
Bemisia tabaci is an important pest on greenhouse vegetables. In order to study the sustainable control of B. tabaci,the comprehensive non-chemical control methods in vegetable experimental bases were used,such as insect source governance,yellow boards trapping and killing,luring reagent trapping and celery-intercropping expelling,etc.,to explore the continuous control effect on cucumber B. tabaci. The results showed that there was negative relationship between the distance of insect source with immigrating amount of adult B. tabaci to greenhouses in the spreading and migrating phase. Insect amount in the source and immigrating amount were positively related. The disturbance to insect source would accelerate the immigration. B. tabaci would choose the nearest new host during the spreadin. B. tabaci prefer yellow boards to cucumbers with ratio between them of 7. 91 ∶ 1 ~ 420. 00 ∶ 1. Yellow boards with either luring reagent or celery had impressive effects on controlling B. tabaci on cucumbers in greenhouses,with the insects decreasing by over 90%. The results indicated that the regional ecological control was an effectiveway for sustainable green control of B. tabaci.
