不同温度条件下,武昌罗索线虫的寄生前期幼虫对致乏库蚊(Culex pipiens quinquefasciatus)二龄幼虫的有效率不同。笔者分别于15℃,18℃,21℃,24℃,27℃,30℃,33℃和35℃进行了24小时及48小时两组不同暴露时间的感染实验。感染24小时的有效率(%)分别是8.5,15,48.5,75.8,94,74,48和11;感染48小时的有效率(%)分别为19.5,23,53,99.3,89.5,67,72.8和23.5。实验表明,15～25℃均可感染,获得感染最高有效率的温度范围为24～28℃,但要获得最多的雌虫及合适的雌、雄性比则为21℃。
Under different temperature conditions, parasitism of parasitism larvae of Lo Wu pathogen Myzus persicae Culex pipiens quinquefasciatus second instar larvae with different efficiency. Infection experiments were conducted at different exposure times of 24 hours and 48 hours at 15 ℃, 18 ℃, 21 ℃, 24 ℃, 27 ℃, 30 ℃, 33 ℃ and 35 ℃ respectively. The effective rates (%) at 24 hours of infection were 8.5, 15, 48.5, 75.8, 94, 74, 48 and 11 respectively. The effective rates (%) at 48 hours of infection were 19.5, 23, 53, 99.3, 89.5, 67, 72.8 and 23.5. Experiments show that 15 ~ 25 ℃ can be infected, the highest infection rate of infection in the temperature range of 24 ~ 28 ℃, but to get the most females and suitable female, male ratio was 21 ℃.
