实蝇对寄主选择的研究进展

Research progress in host selection of fruit fly

实蝇类害虫是以雌成虫将卵产于瓜果内,卵孵化后幼虫在其内取食造成烂果、落果,对瓜果的品质和产量造成严重影响。文章综述了实蝇类害虫对不同寄主、同一种寄主不同品种、寄主果实颜色、果实成熟度、寄主不同受害方式和寄主部位的产卵选择,简述了影响实蝇对寄主产卵选择的因素,并阐述了寄主选择在实蝇防治中的应用。指出实蝇对寄主的选择是多种因素共同作用的结果,提出深入研究寄主植物次生物质对实蝇解毒酶的抑制作用及果实内植物挥发性物质化学成分和营养成分,为今后研制新药剂和合理有效治理实蝇提供理论参考。

Fruit flies spawn inside fruit, and the larve feed on fruit pulp, which caused fruit rot and drop, and had se- rious influence on the quality and yield of fruits. The paper summarized the oviposition preference of fruit fly pests on host kinds, different cuhivars of the same host, fruit color, fruit maturity, different damage methods and host position, resumed the influenced factors on the host choice of fruit fly, described the application of host selection on control of fruit flies. Be- ing host selection of fruit fly causing by multiple-factors role, further research is needed on inhibitory role of plant secondary substances on detoxifyiug enzymes of fruit fly, and chemical and nutritious components of volatile in fruits to provide references for developing new chemicals and rationally controlling fruit flies.
