食芽象虫(x,?inophorus sp),属鞘翅目,象虫科.是一种食性杂,为害重的虫害.据近年来调查,我省太谷、稷山、中阳等主要枣区发生非常普遍.此虫除在苗圃为害各种苗木外,在早春时期,当枣树刚发芽,食芽象虫成虫即开始为害枣树嫩芽,导致大量幼芽枯死,造成严重减产.如今年5月上旬在太谷地区检查,枣树嫩芽被害率达45-100%.每个芽最多有虫4头,最少为1头.因此,为了寻找有效的防治办法,我们进行了室内药效测定及田间药剂防治试验.现将所得结果,整理如下:
It is a food-borne, heavy pests .According to recent surveys, our province Taigu, Jishan, Zhongyang and other major areas of jujube Occurrence is very common .In addition to nurturing the nursery in addition to various nursery stock, in early spring, when the jujube just germinated, the sprouts of insect buds like jujube began to shoot buds, resulting in a large number of young shoots died, resulting in serious cuts. In early May in the Taigu area inspection, jujube shoots damage rate of 45-100%, each bud up to a worm 4, at least 1. Therefore, in order to find an effective control measures, we conducted the indoor efficacy Determination and field of pharmaceutical control test.The results will now be collated as follows:
