食丝谷蛾Hapsifera brabata Christoph的新记述

1979年首次发现食丝谷蛾为害段木栽培黑木耳菌丝后,随即进行了本项研究。本文所指出的这一害虫在我国木耳产区的分布与为害,以及记述的形态特征、生物学特性,国内尚未见有记载。

A PRELIMINARY STUDY OF HAPSIFERA BRABATA CHRISTOPH

Hapsifera brabata Christoph was widely distributed in Hubei, Honan, Sichuan and Shansi provinces. It was one of the most harmful peste to Auricularia auricula in bed-log cultivation. The insect was also found harmful to Tremella fuciformis and Lentinus edodes. It was found that H.brabata Christoph had two generations per year in Wuhan and Dahongshan. The first generation usually takes place from Middle May to late July, while the second generation from early August to early October. The eggs of the pest are usually deposited at the innoculation spot of Mu-re and the base of the sporophore of the fungus. The larvae survive through the winter in between the combium and xylem of the wood logs. The adults appear between middle May and late July.
