不同性诱剂诱捕器类型与剂量对亚洲玉米螟的诱蛾效果

目的]筛选巴彦淖尔地区亚洲玉米螟防治效果较好的性诱剂诱捕器类型和剂量。方法]采用两因素完全随机设计,研究4种类型和4种剂量的性诱剂诱捕器对亚洲玉米螟的诱蛾效果。结果]不同类型性诱剂诱捕器的诱蛾效果存在极显著差异,其中水盆式和三角式诱捕器的诱蛾效果显著优于瓶水式和飞翼式;不同剂量性诱剂诱捕器的诱蛾效果也存在极显著差异,在一定范围内,诱捕器剂量越大,诱蛾效果越好。结论]生产实践中应优先选用水盆式和三角式诱捕器,同时适当提高诱捕器剂量。

Effects of Trap Device Type and Dosage of Different Sex Attractants on the Trapping Efficacy of Ostrinia furnacalis

Objective] To screen the proper trap device type and dosage of sex attractants with relatively good control effect on Ostrinia furnaca-lis in Bayannur Area.Method] Two-factor random design was adopted.Effects of four types and four dosages of trap devices of sex attractants on the trapping efficacy of Ostrinia furnacalis were researched.Result] Different types of trap devices of sex attractants had extremely significant differences in trapping efficacy of O.furnacalis.Among them, basin type and triangle type were superior to the bottle of water type and flying wing type.Different dosages of trap devices of sex attractants had had extremely significant differences in trapping efficacy.Within certain range, greater dosage had better trapping efficacy of O.furnacalis.Conclusion] During practical production, basin type and triangle type of trap device should be adopted;and the dosage of trap device should be properly enhanced.
