稻田是我国三带喙库蚊、中华和雷氏两种按蚊的主要孳生场所,因此稻田灭蚊在整个灭蚊措施中举足轻重。稻田化学除草是农业现代化重要标志之一。除草剂若能同时杀灭蚊的幼虫,则可大幅度降低其种群数量,防制多种疾病。1988～1992年我们对各类稻田化学除草剂进行了实验室灭蚊蚴试验,证实我省研制的灭草丹膜剂对预防稻田蚊蚴孳生有良效。
Paddy field is the main breeding place of Culex tritaeniorhynchus, Chinenchida sinensis and Leishmania in our country. Therefore, the anti-mosquito in paddy field is of great importance in the whole anti-mosquito measures. Paddy chemical weeding is one of the important symbols of agricultural modernization. Herbicides can kill mosquito larvae at the same time, which can greatly reduce the number of their populations and prevent various diseases. From 1988 to 1992, we carried out laboratory tests on mosquito-killing of various types of chemical herbicides in paddy so as to confirm the effectiveness of herbicide danf in the province in preventing the breeding of mosquito larvae in rice fields.
