摘要
本文报道滇南景谷县杧果园1987～1988年两代的果核杧果象生命表,文中包括该害虫几种主要死亡因素作用的分析和预测下一代的发展趋势;据对该虫产卵分布的调查和判断,卵的空间分布型符合负二项分布和奈曼分布;并介绍了杧果象的防治现状和方法,包括改进果园卫生条件以及用敌杀死、锿速灭杀丁、巴丹和灭幼脲等药剂对卵的防治效果。5%锿速灭杀丁乳油(1:2000)、98%巴丹可溶性粉刺(1:1500)和 GT—3混合液的杀卵效果为70.42%。
This paper includes the life-span table of Sternochetus olivieri Faust from 1987～1988 in a mango orchard of Jinggu County,Southern yunnan,China, and the analysis of effects of Several major factors to the mortality of this pest.According to the sample studies of oviposition data of this insect,the egg spatial distribution accords with negative binomial distribution and conta- gious distribution.The present control status of this mango weevil is reviewed. The weevil control measures include improved orchard santitation treatments and timely application of some ovicides,such as Detamethrim,Esfenvalerate, Padan and Dimilin.The mixed solution of Esfenvalerate(1:2000)and Padan (1:1500)and GT—3(a plant extract)has shown a promising killing effect of 70.42%.
