摘要
二化螟性诱芯的存贮期对田间雄蛾诱捕量有明显影响。试验在长春市进行 ,根据诱芯存贮期长短设置 2个处理 ,分别为 - 18℃条件下存贮 2~ 6个月和同样条件下存贮 33~ 37个月。结果表明 ,从 5月 19日到 9月 2 0日两种贮存期的诱芯平均每盆每日诱蛾量分别为 35 8头和 5 5头 ,后者下降 84 6 %。两种贮存期处理的单盆 1日最大诱蛾量分别为 2 2 3头和 2 0头 。
Effects of storage duration of sex pheromone septas on male catches of rice stem borer, Chilo suppressalis (Walker) were evident. Field tests were carried out using water tray traps with two different treatments in Changchun in 1998. Sex pheromone rubber dispersers were stored for 2-6 months and 33-37 months under -18℃, respectively. The results showed that male moth catches stored for 2-6 months and for 33-37 months were 35.8 and 5.5 per trap per night during the period from May 19 to September 20, respectively. The maximum catches of 1 trap in single night were 223 and 20, respectively. However the peak catch dates of two different treatments were basically consistent.
