水果害虫斑翅果蝇体内微生物菌群研究进展

Prospective of the researches on microbiota of spotted wing Drosophila

斑翅果蝇是一种在全球范围内造成危害的重要水果害虫,其主要分布于亚、美、欧三大洲。斑翅果蝇的产卵器可以刺破水果表皮,将卵产在未完全成熟的水果中,卵孵化为幼虫后,幼虫取食水果,直接降低产量,从而对水果产业造成损失。近年以来,越来越多的研究表明昆虫微生物对宿主昆虫影响很大。例如昆虫微生物可以调控寄主昆虫的生长发育、个体适应性及生殖等。昆虫与其共生微生物间的关系成为昆虫生物学研究的热点内容。本文综述了近些年关于斑翅果蝇微生物多样性的研究,探讨了微生物菌群及内共生菌Wolbachia对斑翅果蝇生长发育、行为、生殖、抗病毒等的影响,以便为寻找控制斑翅果蝇种群的策略提供参考依据。

Drosophila suzukii(Matsumura)(spotted wing Drosophila)is a notorious pest of small and stone fruits,and causes damage across Asian,American and European continents.Unlike most other Drosophila species,female D.suzukii flies lay their eggs in ripening and ripe fruits and the hatched larva eat inside,thereby causing substantial economic losses to the fruit industry.Insect-associated microbes are essential in manipulating insect physiology and ecology,such as insect development,fitness and reproduction.Here,we review recent researches on the diversity of microbes in D.suzukii and the functions of microbes in D.suzukii biology.That information may provide clues for searching strategies to control D.suzukii populations.
