The rates of development of Lagenidium giganteum were determined in the four larval instars of Culex quinquefasciatus Say held at 15, 20, 25, 27, 30, and 34 degrees C. The fastest development was in second instars held at 34 degrees; vesicles and oospores occurred in 50% of the larvae (the median development time) 19.7 and 25.0 h, respectively, after infection. The greatest median time to the formation of vesicles was in third instars at 15 degrees C (185.6 h) and for oospores was in second instars at 15 degrees C (152.3 h). The fungus did not form oospores in fourth instars at 15 degrees C. The median developmental rates of vesicles and oospores in each instar were fit to the Sharpe & DeMichele model, which may be used to predict the effects of different temperatures on the in-vivo developmental rate of the fungus.
在15、20、25、27、30和34摄氏度的温度条件下，测定了巨型拉格尼德菌在致倦库蚊Say的四个幼虫龄期内的发育速率。发育最快的是在34摄氏度下饲养的二龄幼虫；感染后，分别在19.7小时和25.0小时，50%的幼虫（中位发育时间）出现了泡囊和卵孢子。形成泡囊的最长中位时间出现在15摄氏度下饲养的三龄幼虫中（185.6小时），而形成卵孢子的最长中位时间出现在15摄氏度下饲养的二龄幼虫中（152.3小时）。在15摄氏度下，该真菌在四龄幼虫中不形成卵孢子。每个龄期内泡囊和卵孢子的中位发育速率符合Sharpe & DeMichele模型，该模型可用于预测不同温度对该真菌体内发育速率的影响。
