| 摘 要： | 暗黑鳃金龟(Holotrichia parallela Motsch)是花生最重要的地下害虫之一。年生一代,以老熟幼虫和少数成虫越冬。8月上旬到9月中旬,即花生幼果期到成熟收获前是三龄幼虫严重为害时期。发生区内的植被组成,产卵及孵化期内的降水和土壤水分是影响种群分布和种群数量变动的主导因素。不同生境内的越冬幼虫无滞育特性,春季均不上移为害,直接在越冬处化蛹,因此,必须在花生生长期进行防治。成虫产卵盛期到幼虫孵化盛期,花生植株在封垄以前是生长期防治的有利时期。应用5%辛硫磷、地亚农颗粒剂,每亩5斤,或6%666毒土(1:80斤土)顺垄撒施复土,有明显的治虫增产效果,已在生产中推广应用。

| Abstract: | The black chafer is a dominant species among the peanut white grubs complex in Shantung province. It has one generation a year and the winter is passed as matured larvae and in few cases as adults.The beetles are the leaf feeders on the shrubs, preferring especially the leaves of elm. The fecundity is closely correlated with food nutrition.Incubation period lasts for 10 days on the average. The duration of first and second instar larva is 17.2 and 16.6 days respectively.From August to middle September, the third instar larvae severely injure the groundnuts.The component of vegetation, rainfall and water content of soil during July and early August signicantly affect the population distribution and fluctuation.The period at the peak of oviposition and flowering of peanut is the critical moment to control this grub. Application with 5% Phoxin and Diaxonon granules at the rate of 2.5 kg per mu or 6% rBHC at the rate of 0.5kg per mu mixed with 40 kg of soil by broadcasting along the row of peanut plants and immediately ploughed into the soil may give an excellent control. |
