The Control Effect of Encarsia formosa Combined with Yellow Sticky Trap in the Control of B.tabaci on Tomatoes in Green Houses
摘要
Abstract
[Objective]The purpose of this study is to discuss the combination effects of Encarsia formosa and yellow sticky trap in the control of Bemisia tabaci on tomatoes growing in green houses . [ Method] Encarsia formosa was released once at 5 - 7days interval and it will continue to be released 5 times under controlled condition, the amount of whose adults are less than 3 heads/plant, and the larvae are less than 2 heads/plant . The release amount of Encarsia formosa each time is about 5 000 heads/667m2. [ Result]The average emergence rate of Encarsia formosa is approximately 84 .35 ％ , and the highest parasitic rate is 73 ％ . It is about 35 days between the initial release date and the foundation of population, and it took about 2 months to take over the Bemisia tabaci population. The investigation of vertical distribution indicated that, Encarsia formosa is mainly located on the middle and low parts of the plant dunng the early stage of tomato growing, and moved to the middle and top parts of the plant in the late stage of tomato growing along with the movement of Bemisia tabaci . The regularity of horizontal distribution is high → low →high→low →high from east to west (from door to inside) . [Conclusion] The release of Encarsia formosa combined with yellow sticky traps showed remarkable effect in the control of B. tabaci on tomatoes growing in green houses. The yellow sticky trap can reduce the number of adults of B. tabaci significantly but showed very little effect in trapping of Encarsia formosa .关键词
