防制蚊虫是控制蚊媒传染病疟疾、乙脑、丝虫病等的重要措施。随着杀虫药的广泛应用,蚊虫逐惭产生了抗药性;同时,杀虫剂因污染环境;杀害非靶生物;破坏生态平衡,已引起人们的严重关注。我们试用家鸭吞食蚊蚴、蚊蛹,控制孳生地的蚊幼、蚊蛹密度,获得了较满意的效果。现将实验初步结果报告如下:材料与方法一、材料:试验用鸭系由市场上购买或专业户牧养之家鸭。二、方法:放牧试验观察,选择不同类型之蚊虫孳生地,包括稻田积水、池塘、粪池等处。并于孳生地内选取若干样点进行采样,采样方法为:用边长,高均为0.33m 的方
Control of mosquitoes is an important measure to control mosquito-borne infectious diseases such as malaria, Japanese encephalitis and filariasis. With the wide application of insecticides, mosquitoes have become resistant to insecticides. At the same time, insecticides have caused serious concern due to environmental pollution, killing non-target organisms and destroying their ecological balance. Our trial duck swallowing mosquitoes, mosquito pupae, mosquito control mosquito breeding ground, mosquito pupa density, obtained more satisfactory results. The preliminary results of the experiment are reported as follows: Materials and methods First, the material: The test duck with the family purchased by the market or professional households ducks. Second, methods: grazing test observation, choose different types of mosquito breeding places, including paddy water, ponds, septic tanks and other places. And in the breeding ground to select a number of samples for sampling, sampling method: with the side length, height are 0.33m square
