乌桕金带蛾核型多角体病毒初步研究

A PRELIMINARY STUDY ON THE NPV OF EUPTEROTE SAPIVORA

乌桕金带蛾(Eupterote sapivora Yang)俗称合辣子、乌桕毛虫,属鳞翅目,带蛾科。由北京农业大学杨集昆教授定名为一新种。主要危害乌桕、泡桐、杨树等13种经济和用材树种,是贵州乌桕产区最严重的害虫,年发生面积约100多万亩。不但造成乌桕籽大幅度减产,而且降低乌桕籽出油率近10％,给农林业生产造成巨大的经济损失。

A nuclear polyhedrosis virus was isolated from the corpse of larva of Eupterote sapivora Yang in Guizhou Province, China. The back infection showed that the NPV is highly pathogenic to the insect. Under transmission and scanning of electron microscopy, the size of polyhedra ranges 1 540~3 380 nm and that of virions 380~460 nm. Ultra-thin sections showed that there are 2 or 3 virions in each bundle.
