摘要
1997～ 1 998年 ,应用二化螟性诱剂对越冬代二化螟进行了田间诱捕试验。结果表明 ,载体为橡皮塞的二化螟性诱芯田间诱杀持续期达 34d以上。每公顷设 30、45和 90个诱盆的诱杀区卵块量均比对照区下降 6 0 %～6 8% ,卵量下降 74% 。
Field tests of the effects of the mass trapping with synthetic sex pheromone on tice stem borer, Chilo suppresalis (Walker), were conducted in Guangde County of Anhui Province in 1997-1998. The results showed that 60%-68% of decrease rate in the number of egg masses was caused by laying out green rubber pheromone dispersers 30,45,90 dish/hm 2. The number of eggs was reduced by 74% and the percent of dead tillers was decreased, too.
