摘要
在人工饲喂系统上研究了猫蚤的交配习性及雄蚤对雌蚤化学提取物的发应。结果表明 ,当 5雌 1雄在饲养盒内时 ,该雄虫可与其他雌虫进行多次交配 ,连续 8小时内交配达 4 8次 ,交配时间平均持续 6 .6分钟 ,两次交配的间隔时间平均为 2 .5分钟。当 1雌 5雄时 ,交配时间平均持续 11.1分钟 ,交配间隔时间为 12 .1分钟 ,连续7小时内 ,该雌虫与雄虫交配 2 7次。新羽化的雌雄虫吸血前不能交配。当把用雌虫提取物处理过的黑色滤纸片放进只有雄虫的饲养盒时 ,雄虫接触纸片的次数及雄
The mating behavior of cat flea, Ctenocephalides felis (Bouche) was studied on an artificial feeding device. Male and female can mate repeatedly with same partner or different ones. In the situation of male: female ratio of 1:5, each mating lasted an average of 6.6 min, with a mean interval between matings at 2.5 min., compared to 11.1 min and 12.1 min respectively in a cell with 5 males and 1 female. As many as 48 mating events were observed for one male during an 8 h period. One female mated 27 times in 7 h with 5 males in the same cell. Newly emerged males and females can not mate before blood meal and about 24 h blood feeding is required for successful mating. Newly emerged males can not mate with fed females (fed for 48 h), but fed males can mate with newly emerged females who are feeding the blood. Significantly more male contacts and male male mating attempts were observed after the paper treated with female extract was introduced into the cell. The paper contacts and mating attempts were 16.75-32.25 times and 15.75-31.38 times, respectively, on average during a period of 20 min when different doses (FE) of extract were provided.
