摘要: 实验室研究和现场试验表明.近期国内发现的旌德罗索虫(Romanomermis jingdeens-is),是一种有前途的蚊虫生物防制剂.1984年5月间在广东南海地区,在释放旌德罗索虫作防制中华按蚊的试验中,发现该种线虫可伴随被感染四龄幼虫的发育而进入蛹和成虫期寄生,并在检查被感染的成蚊中,有1只雌蚊逸出2条寄生后期幼虫.这种寄生现象在实验室已予以进一步证实。

Abstract: Pupal and adult stages of A. sinensis could be infected with R. jingdeensis when 4th-Instar larvae were exposed to preparasites, and the ratio of nematodes in late 4th-instar carried into adult mosquitoes was much higher than that of nematodes in early 4th-instar. This was the first time that the mermithid parasite was found within the pupal and adult stages of anopheline mosquitoes. Another experiment showed that the nematodes arrested ovarian development in most females, only one female was found with completed ovarian development, so the possibility could not be excluded that the infected adults might serve as a vehicle to spread nematodes to other breeding sites. Infectedmosquitoes appeared to have mating activity because sperms were found in the sperma-theca of an infected adult female. The pupae were insusceptible to prepasraites when they were directly exposed to the nematode.
