柑桔花蕾蛆的成虫产卵在花蕾中,幼虫食害花蕾,使其不能开放而呈球圆形,直接影响柑桔开花结果,是柑桔的重要害虫。近年来由于六六六等停止使用,使该虫危害日趋严重。甲基对硫磷、克百威、辛硫磷和二嗪农虽有较好效果,但前二者毒性较高,后二者又供应不足,故需进一步寻求更多的高效、低毒药剂来代替有机氯等。为此,作者于1986～1987年用溴氰菊酯和pp321等对柑桔花蕾蛆进行了田间防治试验,现简报如下。 Citrus bud maggot adult spawning in the bud, the larvae eat buds, it can not be open and spherical, a direct impact on citrus flowering is an important citrus pests. In recent years, due to the suspension of the use of 666 and other cephalosporins, the insects have become more and more dangerous. Methyl parathion, carbofuran, phoxim and diazinon have good results, but the former two are more toxic and the latter two are in short supply. Therefore, more efficient and less toxic agents need to be further sought Instead of organic chlorine and so on. To this end, the author from 1986 to 1987 with deltamethrin and pp321 and other citrus bud maggot field trials, are presented below.
