摘要: 该文报道黄足真蚋幼期的孳生习性及幼虫龄期组成。卵全部在0.3~3cm深的水中漂浮的茅草叶上采获,在石块和砖头、塑料等杂物上未查到卵。在茅草叶、石块和杂物上共采获728条幼虫,茅草叶、石块和杂物上的幼虫数分别占幼虫总数的57.1%、35.3%和7.6%。共采获217只蛹,茅草叶上蛹数占采蛹总数的78.3%,石块上仅占21.7%,在杂物上未来到。黄足真蚋幼虫分为5个龄期,来到1~3龄幼虫较少,4~5龄较多,占幼虫总数的81.2%,大部分幼虫已为成熟幼虫。

Abstract: The ecological observation of eggs,larvae and pupae of Simulium (Eusimulium) aureohirtum Brunetti in small stream on Baiyun Mountain of Guangzhou,Guangdong Province,10 July,1995.The all eggs were laid on the leaves of maocao and most of the eggs were distributed lower than 0.3-3cm above water level (table). The 728 larvae collected were distributed on maocao leaves (57.1%),rocks (35.3%) and fragment of bricks (7.6%),respectively.The 217 pupae were distributed on maocao leaves (78.3%) and rocks (21.7%), respectively,Five larval instars were estimated from the distribution size of postgenal length.In the middle of July,most larvae were mature (81.2%).
