摘要
在实验室内对中华按蚊和嗜人按蚊的主要繁殖率指标以及雄蚊、未吸血雌蚊和饱血蚊体重等进行实验研究,在温度26±1℃,温度80±10％的实验室内,中华按蚊的产卵率、平均每蚊首次产卵数、孵化率、化蛹率、成成蚊率分别为79.31％、127.29±47.50、86.56％、87.61％、95.89％、89.93％:而嗜人按蚊则分别为75％、114.71±47.37、75.06％、82.42％、94.44％、95.55％:中华按蚊雄蚊、未吸血蚊、饱血蚊体重、平均吸血量分别为1.12±0.24、1.44±0.32、3.94±0.892.50mg:而嗜人按蚊则分别为0.93±0.24、1.06±0.25、2.93±0.55、1.847mg。经统计学分析,它们的产卵率、平均产卵数和羽化率没有显著性差别,而孵化率、化蛹率、成成蚊率、蚊体重(包括雄蚊、未吸血蚊和饱血蚊)等则有非常显著性差别。中华按蚊羽化为成虫的数量与工龄幼虫之比(S值)为0.7562:而嗜人按蚊的S值则为0.
Experimental study on main fecund indicators of An. sinensis and An. anthro pophagus was carried out, as well as the bodyweight of male , unfed and fed female mosquitoes. Under laboratory tmeperature 26±C and relative humidity 80±0% ,the egg laying rate,mean first egg laying permosquito ,egg hatching rate , pupating rate,adult rate is 79. 31%,127. 29 ?47. 50.86. 56%, 87. 61% ,95. 89 % . 89 . 93% , respectively ; while in case of An. dnthrophogus it is 75 % .114. 71±7. 37.75. 06% . 82 . 42% , 94. 44% and 95. 55%,re spectively. The bodyweight of male, unfed.fed mosquito .mean amount oi blood - taking of An. sinensis is 1. 12 ±0. 24,1. 44±. 32.3. 94±. 89-2.50mg, respectively: while in case of
An. anthropophagus.it is 0. 93 ±0. 24-1. 06±0. 25,2. 90±. 55.1. 87mg ,respectively. There
gence rate statistical significance in the comparison of egg laying rale.mean egg number and emergence rate. There is statistical significance in the comparison of egg hatching rale , pupation rate. ,adult rate and mosquito bodyweight including malt .unfed and fed female mosqnioes. The ratio of the adult number bo first instar larva numbe r(S-value)of An. sinensis is 0. 7562, while it is 0. 7437 in case of An. anthropopagus.
