巨膜长蝽寄主选择的测试及寄主植物的调查

目的]判断巨膜长蝽(Jakowleffia setulosa)在选择寄主植物的各阶段中起到主要作用的感觉器官。方法]对巨膜长蝽的寄主选择进行了测试,并对其寄主植物范围进行了调查。结果]巨膜长蝽对寄主植物的选择中,嗅觉对其搜索寄主植物起到关键作用,触觉及味觉对其取食寄主影响明显,而寄主植物的颜色、形状和质地对其搜索寄主无影响。巨膜长蝽为广食性昆虫,其寄主植物涉及到10科22种,其中有5科5种栽培作物。结论]为探究巨膜长蝽聚集成灾的形成机制及防治对策提供了理论依据。

Selective Testing and Investigation on Host Plants of Jakowleffia setulosa

Objective ] The aim was to explore the main sense organ of Jakowleffia setulosa played a k＇y role in researching host plants. Meth- od ] The host selection of J. setulosa was tested, furthermore the host plants of J. setulosa were inves,~igated. Result ] The smell of J. setulosa played a key role in researching host plants, meanwhile touch and taste obviously impacted its feeding, but the color, shape and texture of host plants had no effect on its researching host plants. J. setulosa was a polyphagous insect. The range of host plants related to 10 families and 22 spe- cies,including five species cultivated crops in five families. Conclusion] The research results provide theoretical basis for the study on formation mechanism of aggregation and disaster forming of J. setulosa and control measures.
