摘要
近年来,在广西等地的撑绿竹林中爆发了大面积的长足竹大象虫害,其危害之大,已经严重影响了当地撑绿竹产业的发展,也制约了该竹种的大面积推广与应用。为了有效防治该虫害,文中以近年来广西区爆发的长足竹大象虫害为研究对象,采用不同药剂种类(A)、施药方法(B)、药剂浓度(C)及施药次数(D)等防治手段,用感虫率和感虫指数作为虫害控制效果的考核指标,就不同药剂处理对虫害的控制效果进行了连续3年的试验研究。结果表明:对该虫害控制效果较好的药剂为A2(赣竹药Ⅰ+粒粒金+锐劲特)和A1(杀虫双+万金丰+氧化苦参碱);最适药剂浓度为C1水平,即600倍;最适用的施药方法为B3(蔸部土壤+喷雾)和B1(竹腔注射+竹基节削青涂抹+蔸部土壤);最佳施药次数为D4,即5次。
In recent years, Cyrtotrachelusbuqueti longimanus Fabricius break out in Bambusa pervariabilis × Dendrocalamopsis daii forest at large areas of Guangxi, it seriously hinder development of B. pervariabilis X D. daii industry and popularisation and utilization of the bamboo species. In order to effectively control damage by the insect, taking C. longimanus Fabricius in Guangxi as research object, control effects of different kinds of pesticides (A), application methods (B), concentrations (C) and times of application (D) on the insect were researched in continuous 3 years, using infection rate and infection index as control effect indexes. The results show that it has better control effect to apply 5 times (D4) Gan bamboo pesticide+ Lilijin + fipronil (A2) or dimehypo + Wanjinfeng + oxymatrine (Al) at 600 times concentration (C1) by the methods of base soil application + spraying (133) or injection in stem + cut the green base application + base soil application (B1).
