灵芝膜喙扁蝽的生物学特性观察

灵芝膜喙扁蝽在浙江每年发生２代，若虫期为５龄，以成虫在土中的椴木周围及灵芝棚内紧贴土面的木片、竹片下越冬。该虫具有群集、假死、喜阴等习性。６～１０月份为发生盛期，以灵芝菌丝为食，灵芝受其危害产量明显下降，品质降低。

Observation of the bionomics of Mezira membranacea (Fabr.).

Bionomics of Mezira Membranacea (Fabr.) were investigated both in the fields and laboratory. The results showed that the insect had two generations a year in Zhejiang Province and the larval stage consisted of five instars. It overwintered as adults around Ganoderma lucidum logs in the soil and under the wood of bamboo chips in the G. lucidum sheds. The characters of aggregation, false death, and negative phototropism were found. Serious injury period of the insect was from June to October. The insect sucked the juice from the mycylium of G. lucidum, resulting in great losses both in quantity and quality of G. lucidum.
