泥鳅24尾分为3个年龄级(0~+,1~+,2~+),每个年龄组又分为塘水和污水组,在不同恒温(10—31℃),分别饲喂蚊幼虫,结果表明:摄食蚊幼虫的3个塘水组平均136.6头/天。尾;3个污水组平均165.3头/天·尾,污水组高于塘水组。在不同恒温(10—31℃)时,以26—28℃时最高(282头/天·尾);10℃时最低(8头/天.尾)。解剖稻田中泥鳅33尾观察,以摄食水生动物为主,以水生植物为辅。肠内有蚊幼虫6尾(占总数18.2%),但占肠内容物比例较小。解剖污水沟中泥鳅14尾,肠内几乎充满蚊幼虫的有11尾(占总数78.5%);肠内有蚊成虫的1尾(占总数7.1%)。在污水沟和稻田放养泥鳅,是一种值得进一步探讨的生物灭蚊途径。
Twenty-four loaches were divided into three age groups (0 ~ +, 1 ~ +, 2 ~ +). Each age group was divided into pond water and sewage group. Larvae, the results showed that: the three ponds consumed mosquito larvae group average 136.6 head / day. The average of the three sewage groups was 165.3 days per day, while the sewage group was higher than that of the pond water group. At the same temperature (10-31 ℃), the highest at 26-28 ℃ (282 / day · tail); the lowest at 10 ℃ (8 / day. 33 loaches were dissected to observe the paddy fields, feeding mainly aquatic animals, supplemented by aquatic plants. The intestine has 6 mosquito larvae (accounting for 18.2% of the total), but accounting for a small proportion of intestinal contents. Anatomy of the sewage ditch in the 14 loach, intestinal almost full of mosquito larvae 11 (78.5% of the total); intestinal intestinal mosquito adult 1 (7.1% of the total). The loach stocking in sewage ditches and paddy fields is a biological approach to mosquito deserving further exploration.
