樟叶蜂生物学特性及防治技术的研究

樟叶蜂在湖北1年发生3代，以老熟幼虫在土壤中越冬，3月中、下旬至5月中、下旬为发生为害期。幼虫从叶缘或近叶脉处开始取食，每隔15－16min排便1次；老熟幼虫具浓烈的松香味，并有假死性。采用冬季翻耕及用100亿孢子／g青虫菌菌粉700倍液喷药，能有效地控制樟叶蜂的发生。

Study on the Biological Characteristics of Moricella rufonota Rhouer and Its Control

Moricella rufonota Rhouer generates 3 generations in one year. The old larva can over winter in soil. Its period of harm is about from March 20 to May 20. The larva first eats the leaf margin or the leaf nearby the vein, and drains off some feces per 15-16 minutes. The old larva can send Out strong taste of pine tar, it has false death character. Through experiments, the Moricella rufonota Rhouer can be effectively controlled by winter tilling and by spraying Bt dust that is l010spores per gram of 700 folds diluted for leaf.
