摘要
利用黄板引诱枣叶瘿蚊成虫与定时定点调查幼虫相结合的方法监测枣叶瘿蚊消长动态。监测发现,枣叶瘿蚊在阿克苏市1年发生4代。从总的发生趋势来看,第1代和第2代的发生数量最高。根据其发生趋势明确了防治的关键时期应放在第1代幼虫期,可有效控制枣叶瘿蚊的下一代发生数量。此外,对枣叶瘿蚊采取药剂防治和黄板诱杀,试验结果表明,供试药剂中48%毒死蜱EC效果最好,其防效达到了92.79%;5%吡虫啉EC、25%氰·马EC效果欠佳,防效仅达78%左右;挂黄板和不挂黄板的效果比较,表明挂黄板的效果更好。
In this article,by utilizing yellow sticky card to attract male of Dasineura datifolia J iang incor- porated with fixed point investigation of larvae, the growth and decline trends of Dasineura datifolia Jiang in Aksy were investigated. The result demonstrates that 5 generations of Dasineura datifolia Jiang hap- pened every year in Aksy, the first generation and the second generation reach a maximum number in Aksy. It is very important for making the control measure at the larvae stage of first generation, which could inhibit the quantity of their next generation. In addition, by utilizing insecticide and yellow sticky card against Dasineura datifolia J iang,the results of trial showed that 48% Chlorpyrifos EC had the best control efficiency,the control effect is 92.79 %. While 5 % Imidacloprid EC and 25 % Fenvalerate-Malathi- on EC effect is unsatisfactory, the control effect is about 78%. The comparison of the two effects of hitched up the yellow sticky cards and didn＇t use the cards manifests that by comparison, the hitched up yellow sticky cards had better control efficiency.
