摘要：【目的】调查浙江省杭州市雷竹(Phyllostachys violascens‘Prevernalis’)林造瘿害虫的危害情况,研究雷竹虫瘿内昆虫的生物学特性,为发展高效的造瘿害虫防控技术提供基础。【方法】采用抽样法调查造瘿害虫的危害情况;采用室内饲养法和生物测定法研究雷竹虫瘿内昆虫的物种组成、数量特征、羽化出孔节律等生物学特性。【结果】造瘿害虫的有虫株率在85.00%以上,每盘枝条的平均虫口在18.35头以上。雷竹虫瘿内有竹泰广肩小蜂(Tetramesa bambusae)、刚竹泰广肩小蜂(T.phyllostrachitis)、竹瘿广肩小蜂(Aiolomorphus rhopaloides)和刚竹瘿蚊(Procystiphora sp.)4种造瘿害虫,竹泰广肩小蜂和刚竹泰广肩小蜂的个体数量占造瘿害虫总数的96.20%,是雷竹上最主要的造瘿害虫;竹泰广肩小蜂的初始卵量多于刚竹泰广肩小蜂,并且其卵体也更大,但竹泰广肩小蜂雌成虫的寿命短于刚竹泰广肩小蜂。雷竹虫瘿内有栗瘿旋小蜂(Eupelmus urozonus)、纹黄枝瘿金小蜂(Homoporus japonicas)、中国枝瘿金小蜂(H.sinensis)、具点刻腹小蜂(Ormyrus punctiger)、黄色食瘿广肩小蜂(Sycophila flava)、黄腹长角金小蜂(Norbanus longifasciatus)和竹瘿长角金小蜂(N.aiolomorphi)7种寄生蜂,个体数量最多是栗瘿旋小蜂。【结论】竹泰广肩小蜂和刚竹泰广肩小蜂是雷竹林主要的造瘿害虫;刚竹瘿蚊为浙江省新报道的竹子造瘿害虫。雷竹虫瘿内寄生蜂的数量多,这些寄生蜂是造瘿害虫种群抑制的重要生物因子,应加以保护和利用。
【Objective】In this study,the damage of gall-induced pests in Phyllostachys violascens‘Prevernalis’forests in Hangzhou city,Zhejiang province was investigated,and the biological characteristics of gall insects were studied,which could provide a basis for developing efficient control technology of gall-induced pests.【Method】In the study,sampling method was used to investigate the damage of gall-induced pests.Indoor rearing methods and bioassay methods were used to study the biological characteristics of the species composition,quantitative characteristics,and eclosion rhythms in gall insects.【Result】The results showed that the damage ratio of gall-induced pests in Ph.violascens‘Prevernalis’forest exceeded 85.00%,and the average insect population exceeded 18.35 per disc of branch.In the study,four species of gall-induced pests,Tetramesa bambusae,T.phyllostrachitis,Aiolomorphus rhopaloides and Procystiphora sp.were reared from the galls of Ph.violascens‘Prevernalis’.The individual numbers of T.bambusae and T.phyllostrachitis accounted for 96.20%of the total,which were the most important gall-induced pests on Ph.violascens‘Prevernalis’.The initial egg load and egg size of T.bambusae were larger than those of T.phyllostrachitis,but the lifespan of female T.bambusae was shorter than that of T.phyllostrachitis.Seven species of parasitic wasps,Eupelmus urozonus,Homoporus japonicas,H.sinensis,Ormyrus punctiger,Sycophila flava,Norbanus longifasciatus and N.aiolomorphi,survived in the galls of Ph.violascens‘Prevernalis’.E.urozonus had the largest number of parasitic wasps.【Conclusion】T.bambusae and T.phyllostrachitis were the most important gall-induced pests on Ph.violascens‘Prevernalis’.Procystiphora sp.is a newly reported gall-induced pest of bamboo in Zhejiang Province.Seven parasitoid species survived in the galls of Ph.violascens‘Prevernalis’,which were important biological factors for inhibiting gall-induced pests,and these parasitic wasps should be protected and fully utilized.
