为了寻找简单易行、经济有效的防治措施,1976年我们在德保县马隘公社用活雌蛹进行稻瘿蚊性诱试验,效果较好。每盆放置活雌蛹5头,最高诱雄数达960头。说明稻瘿蚊活雌蛹已能分泌性外激素,对雄虫具有诱集作用。蛹较成虫的使用时间长,放置方便,使利用性诱作为防治措施更为现实。在德保县各级党委的领导和社员的大力支持下,1976年晚稻推广使用面积4603.5亩,很受群众欢迎。 (一)性诱器的选用
In order to find a simple and cost-effective prevention and control measures, in 1976, we used live female pupae in the Subei community of Dabu County for the test of rice louse mosquitoes. Five live pupae were placed in each pot, and the maximum number of lure was 960. These results indicated that the female pupae of rice gall midge could secrete pheromone and had the trapping effect on male. Pupa adults than the use of a long time, easy to place, making use of induced as a prevention and control measures more realistic. Under the strong support of leaders and members of Party committees at all levels in Debao County, the area for the promotion of late rice in 1976 was 4603.5 mu, which is very popular with the masses.
