Abstract

Females of Culex pipiens pallens are rarely inseminated at temperatures above 30 degrees C. Insemination and egg-hatching rates (F2) were examined in females of hybrids (F1) between Culex pipiens pipiens and Culex pipiens quinquefasciatus at 25 degrees C and 30 degrees C to examine temperature-dependent reproductive activity. Insemination rates were very high in hybrid females (F1) at 25 degrees C and 30 degrees C, and egg-hatching rate (F2) also was high at both temperatures. Crosses between Cx. p. pipiens and Cx. p. quinquefasciatus did not show insemination rates and egg-hatching rates similar to the rates observed in Cx. p. pallens, suggesting that the hybrids expressed reproductive activity characteristic of Cx. p. quinquefasciatus.

摘要

在温度高于30摄氏度时，淡色库蚊雌蚊很少受精。在25摄氏度和30摄氏度条件下，对致倦库蚊和淡色库蚊杂交种（F1）雌蚊的受精率和孵化率（F2）进行了检测，以研究温度依赖性生殖活动。在25摄氏度和30摄氏度时，杂交雌蚊（F1）的受精率非常高，并且在这两个温度下孵化率（F2）也很高。致倦库蚊和淡色库蚊之间的杂交并未表现出与淡色库蚊中观察到的受精率和孵化率相似的情况，这表明杂交种表现出了致倦库蚊的生殖活动特征。
