Keyword:  B型烟粉虱杀虫剂毒力作用;
Abstract: 采用浸叶法,在室内测定了9种药剂对B型烟粉虱不同虫态的毒力大小,结果表明,9种药剂对烟粉虱成虫的毒力大小依次为:阿维菌素>啶虫脒>印楝素>苦内酯>吡虫啉>毒死蜱>功夫>鱼藤酮,噻嗪酮对成虫无毒杀作用;对烟粉虱低龄和高龄若虫的毒力大小依次为:阿维菌素>啶虫脒>苦内酯>印楝素>吡虫啉>鱼藤酮>噻嗪酮>功夫>毒死蜱和阿维菌素>苦内酯>啶虫脒>印楝素>吡虫啉>鱼藤酮>噻嗪酮>毒死蜱>功夫;9种药剂对烟粉虱卵都没有表现出明显的毒杀作用.此外,B型烟粉虱成虫接触经印楝素处理的甘蓝叶片后,在未经印楝素处理的叶片上产卵量显著下降,所产卵的孵化率显著降低.
