柿伪安瘿蚊主要危害浙江省兰溪市的本地品种大红柿。其幼虫在当年生枝条皮层下取食并形成虫瘿,严重影响柿子产量。柿伪安瘿蚊在兰溪1a发生1代,以1龄幼虫在柿树受害枝条上的虫瘿内越冬。正常年份5月上旬成虫羽化,降雨量的大小可以直接影响发生量,多雨湿润的年份发生量大,干旱少雨的年份尤其是春季干旱可以明显降低虫口数量。实生苗上虫口数量很少,以野柿实生苗为砧木,大红柿为接穗的嫁接苗上虫口数量最多;春梢上虫口数量较夏梢、秋梢上多。发现柿伪安瘿蚊上有3种寄生蜂,即黑色广肩小蜂、瘿蚊旋小蜂和一种旋小蜂。防治策略应采用抓住成虫高峰期用药,结合检疫与栽培防治,协调生防与化防措施。还讨论了其发生规律和环境影响的关系。
Persimmon pseudo-An Di mosquito major hazard Lanxi City, Zhejiang Province, the local varieties of tomatoes. The larvae in the annual branches of the cortex feeding and the formation of galls, seriously affecting the persimmon production. Persimmon pseudo-An Di mosquito occurred in Lanxi 1a generation, with the first instar larvae in persimmon victim branches overwintering. In normal years, the emergence of adult insects in early May, the size of the rainfall can directly affect the amount of occurrence, rainy and wet years occurred in large quantities, dry years, especially the spring drought can significantly reduce the population. Insect population on the seedlings seldom, to the wild persimmon seedlings as rootstocks, scallops tomatoes as the most on the number of grafted seedlings; spring shoots on the number of insect tip more than the summer, more autumn tip. Found on persimmon pseudo-Anchilles mosquito have three kinds of parasitic wasps, namely, black broad-shouldered wasp, mosquito spinosus and a small spinous bee. Prevention and control strategies should be used to catch the peak drug use, combined with quarantine and cultivation control, coordination of biological control and prevention measures. Also discussed the relationship between its occurrence and environmental impact.
