粘虫棉铃虫对杀虫剂活性的相关性

The relationship of insecticidal activities between Mythimna separata (Walker) and Helicoverpa armigera (H■bner)

研究了37种杀虫剂对粘虫、棉铃虫活性的相关性。结果表明，粘虫对杀虫剂的活性和棉铃虫是一致的，其直线回归式：Y＝164．36＋0．646X相关系数（R）为0．953。R值受棉铃虫对拟菊酯抗性的影响。

The relahonship of insechciclal ashvihes between the oriental armyworm, apthimna separata (Walker) and the cotton bollworm, Hehcoverpa armigera (Hubner) to 37 insechcides has been studied. The results show tha the insechcidal achvihes of insechcides to the oriental armyworm are consistent witn the cotton bonworm and the equstion for the stwght line is Y = 164.36 + 0.646x and the cormlation coefficient R is 0.953. The R value is influsnced by pyrebod resistant in the cotton bollworm.
