本文利用广西中剑水蚤(暂定名)在花园里进行控制白纹伊蚊的效果观察。结果:一次性投放剑水蚤300只,10天后蚊幼的平均密度下降了81.76％,以后一直维持在一个较低的水平。对照区的平均密度一直比实验区高出十至几十倍,容器阳性率亦在10天后明显下降,以后仅在小范围内波动,对照组一直保持在100％,12月才下降至50％,此时实验区的容器阳性率为0.67％,叮咬频率也由原来的33只/15,下降至9只/15,在白纹伊蚊活动高峰期,实验区的叮咬频率为0只/15,而对照区则高达136只/15,有效时间达5个多月。
In this paper, Guangxi Sword Daphnia (tentative name) in the garden for the control of Ae. Albopictus observation. Results: One hundred 300 daphnids were used at one time. After 10 days, the average density of mosquito larvae dropped by 81.76% and remained at a lower level afterwards. The average density of the control area has been ten to several times higher than that of the experimental area, and the positive rate of the container also dropped significantly after 10 days. After that, the average density of the control area only fluctuated within a small range, the control group remained at 100% and declined to 50% At this time, the positive rate of container in experimental area was 0.67%, and the bite frequency dropped from 33/15 to 9/15. At the peak of Aedes albopictus activity, the bite frequency in experimental area was 0/15 , While the control area is as high as 136/15, the effective time of more than 5 months.
