【摘要】 利用枣粘虫聚乙烯塑料管性诱剂对枣粘虫进行了迷向防治试验。迷向剂量分150、300、450、750和1500μg/株5个水平。迷向效果用六个指标作了考查,即诱蛾量、迷向率、交配率、落卵量,孵化率和幼虫残留量。试验结果表明;用1500μg/株的剂量迷向,对枣粘虫有较好的防治效果。更多还原

【Abstract】 Based on the principle of pheromone confusion technique we conduted a experiment of controlling Ancylis saliva with plastic lures made of poly- ethylene tube in date area in Taigu,Shanxi from 1984 to 1987.The experiments have 6 levels (150,300,450,750 and 1500μg/tree),To test the effect,the number of trapped moths,the rate of mating disruption,mating rate,the number of eggs.the rate of hatched eggs and the number of the larvae were investigated.The results showed that the effect of control with 1500ug/tree is better.更多还原
