黄色粘虫板对黄瓜大棚内几种害虫的诱杀效果

在种植黄瓜的大棚内,研究了黄色粘虫板的不同挂板时间对大棚内蚜虫、斑潜蝇、烟粉虱、白粉虱、蓟马、绿盲蝽等6种害虫诱杀效果的影响。结果表明:挂黄色粘虫板的时间越早,大棚内后期的蚜虫、斑潜蝇、蓟马、绿盲蝽、白粉虱的数量越少,即诱杀效果越好;从2月18日起挂黄色粘虫板可以将大棚内的蚜虫、蓟马、绿盲蝽的数量控制在一个较低的水平,将斑潜蝇、烟粉虱的数量控制在一个稳定的水平,但白粉虱数量依然呈增加的趋势;从3月20日起挂黄色粘虫板也可以将大棚内的蓟马、绿盲蝽数量控制在一个稳定的水平,但是控制烟粉虱的效果不显著。

Effect of Trapping Pests by Yellow Sticky Traps in Cucumber Shelters

Planting the early spring cucumber(Cucumis sativus) in the shelters,the effects of trapping pests by the yellow sticky traps with different hang time for six kinds of pests were studied,and the six kind pests were Aphid,Liriomyza sativae Blanchard,Bemisia tabaci Gennadius,Trialeurodes vaporariorum,Thrips flavus Schrank and Lygus lucorum.The results showed that the earlier the hang time of the yellow sticky traps,the less the quantity of Aphid,L.sativae,T.flavus,Lygus lucorum and T.vaporariorum,i.e.the better the effect.Hanging up the yellow sticky traps in the shelters from February 18th,the quantities of Aphid,T.flavus and L.lucorum were controlled under a low level,while the quantities of L.sativae and B.tabaci in a steady level,but the quantity of T.vaporariorum still presented a trend of increase.Hanging up the yellow sticky traps in the shelters from March 20th,the quantities of T.flavus and L.lucorum were controlled in a steady level too,but the control effect of B.tabaci’s was not significant.
