50年代初期,稻瘿蚊在本省部分山区、丘陵区发生,间歇猖獗;50年代中期至60年代,全省基本实现双季连作稻后,稻瘿蚊发生为害明显减少。70年代以来,部分地区大面积种植早稻:(1)迟熟品种,迟插;(2)三季连作稻和中稻;(3)晚稻寄秧,植期延长。为稻瘿蚊创造了良好的繁殖环境和转移桥梁,遇到适宜的气候条件,便猖獗成灾。80年代以后,全省恢复了双季稻连作制,采用早、中熟品种适时移植,使用喹硫磷等有效农药,作好晚稻秧田防治等综合防治措施,较有效地控制了稻瘿蚊的发生为害。
In the early 1950s, the rice gall midge occurred in some mountainous areas and hilly areas of the province intermittently. In the mid-1950s and the mid-1960s, the occurrence of the rice gall midge was substantially reduced in the province after the double continuous cropping rice. Since the 1970s, large areas of early rice have been planted in some areas: (1) late-maturing varieties, late insertion; (2) continuous planting of three-season rice and medium-sized rice; and (3) late rice planting and prolongation of planting. For the rice gall midge mosquito to create a good breeding environment and transfer of the bridge, met the appropriate climatic conditions, they rampant disaster. Since the 1980s, the province has resumed double cropping continuous cropping system, using early and middle maturing varieties timely transplantation, the use of effective pesticides such as quetiapine, make comprehensive prevention and control measures such as late rice seedling control, more effective control of rice gall midge mosquito Harmful.
