摘要/Abstract

摘要： 1989～1991年,在河北省灵寿县,于核桃举肢蛾成虫羽化高峰期,用20％除虫脲5000倍药液防治两次,好果率达95％,对照不防治的树,核桃全部被害。除虫脲还能兼治核桃缀叶螟和刺蛾,对瓢虫的影响也较喷速灭杀丁小。

Abstract: In the experiments conducted during 1989-1991 in the walnut plantations of Lingshou County, Hebei Province, 20% diflubenzuron SC, an insect growth regulator, was diluted 5,000 times and sprayed twice on the walnut trees at the adult emergence peak of Atrijuglans hetaohei, a serious fruit borer of walnuts. As a result, 95% of the fruits on the treated trees were not damaged, while 100% of the fruits were attacked by the pest on the untreated trees. Application of diflubenzuron also controlled some other pest insects, such as Locastra muscosalis, Cnidocampa fluvescens and Parasa consocia, but was safe to beneficial insects.
