四川属于二代粘虫常发区,主要在盆地边缘山区发生,为害玉米、水稻等。近年来,有加重为害水稻的趋势;在山区温湿度不适的年份,下坝为害。例如,1982年大发生,因6月份气温明显偏低,大量粘蛾下坝,而水稻生育期也推迟,老秧多,田间枯黄叶也较多,扩大了粘蛾产卵面。南江县调查113亩水稻,受害面积达30％,其中40余亩受害严重,每亩虫量6万头以上。1982年大发生,全省发生面积428.5万亩,由于预测网形成,测报水平有所提高,及时地指导了防治工作,未遭受严重损失。现将我们的测报和防治经验,介绍如下: Sichuan belongs to the second generation of armyworm habitat, occurring mainly in the edge of the basin mountains, damage to corn, rice and so on. In recent years, there is a tendency to aggravate the damage to rice. In the years where the temperature and humidity in the mountain are uncomfortable, the lower dam is harmful. For example, in 1982, due to the significantly lower temperature in June, a large number of stick moth dam, and the rice growth period is also delayed, more old seedlings, more yellow leaves in the field, expanding the moth spawning surface. Nanjiang County, 113 acres of rice survey, the victim area of ​​30%, of which more than 40 acres of serious damage, more than 60,000 per mu of insect population. Occurred in 1982, the province occurred an area of ​​4285000 mu, due to the formation of the forecast network, reporting level has increased, timely guidance of prevention and control work, without serious losses. Now we report and prevention experience, described below:
