本文报道了释放武昌罗索线虫寄生前期幼虫密度为2500～3000条/m~2时,武昌罗索线虫对自然孳生的白纹伊蚊的平均感染率分别为57.9%和74.4%。据观察,影响感染率的因素主要是寄生前期幼线虫密度、水温、水质及孑孓龄期等。
This paper reports that when the density of parasitism larvae of parasitoid Wuchang loosens was between 2500 and 3000 / m ~ 2, the average infection rates of natural lobar mosquitoes were 57.9% and 74.4%, respectively. It is observed that the main factors affecting the infection rate is nematode nematode density, water temperature, water quality and larvae age.
