本文为生物(鱼类)灭蚊研究的第二部分.作者之一(潘炯华教授),三年前(1978年)曾研究食蚊鱼、胡子鲇、叉尾斗鱼的生物学特性及其胚胎发育.有关资料曾发表在华南师院学报自然科学版1980年第1期117—138页.食蚊鱼灭蚊试验在大面积(2平方公里)孳生地中进行.经过两年的研究,肯定食蚊鱼是一种较好的灭蚊鱼类,它食浮游动物和浮游植物,但更嗜食蚊幼虫.每平方米水面放养10尾食蚊鱼,可使蚊类幼虫密度明显下降,其相关密度指数为0～29.2%(月平均).
This article is the second part of the study on biology (fish) mosquito control. One of the authors (Prof. Pan Jionghua), three years ago (1978) studied the biological characteristics of the mosquito fish, the beardfly, Development of relevant information has been published in South China Normal University Natural Science Edition, No. 1, 1980. 117-138 page mosquito fish mosquito test in a large area (2 square kilometers) breeding ground carried out after two years of research, affirmed Mosquito fish is a better mosquito fish, which eat zooplankton and phytoplankton, but even more susceptible to mosquito larvae per square meter of surface stocking 10 mosquito fish mosquito can make mosquito larvae density decreased significantly, the correlation The density index is 0-29.2% (monthly average).
