关于家蝇(Musca domestica)的生活史,实验观察结果表明:①家蝇生活史:在实验室内从卵→成虫需要9.5～12天以上。卵的孵化率为82～88.4%,幼虫化蛹率为71.5～78.7%,蛹的羽化率为71.3～79%。②成虫羽化后,展翅时间在10～15分最多;静止时间以60～120分为最多;变色时间以24～53分为最多;取食时间为羽化后2～6小时居多,取食持续时间为1～25分。③家蝇性比例:雄蝇与雌蝇,基本上符合1∶1比例。④交配:雌蝇羽化后24小时后方能变配,有效的交配时间约1小时以上。交配次数,以交配1次者为最多,但是也可以进行多次交配,个别的交配次数达10～11次。⑤寿命:实验室内于1984.6～8月及8～10月进行两次观察,家蝇的寿命为1～2个月以上。⑥繁殖力:观察6对家蝇,雌蝇存活时间为15～45天,产卵总数为259～748粒。雌蝇存活15天产卵4次,存活23天产卵9次,存活36～45天产卵12次,说明其繁殖力很强。
On the life history of Musca domestica, the experimental observations show that: (1) Musca domestica life history: It takes 9.5 to 12 days from eggs to adults in the laboratory. The egg hatching rate was 82-88.4%, larvae pupation rate was 71.5-78.7%, and pupae emergence rate was 71.3-79%. ② After emergence, the time of wings spreading was the highest at 10-15 minutes; the resting time was the most at 60-120 minutes; the time of discoloration was at 24-53 points; the feeding time was mostly 2-6 hours after eclosion, feeding duration For 1 to 25 minutes. ③ Housefly sex ratio: male flies and female flies, basically in line with 1: 1 ratio. Â ’£ mating: female flies 24 hours after emergence of change, the effective mating time of about 1 hour or more. The number of matings to the mating one is the largest, but can also be multiple mating, the number of individual mating up to 10 to 11 times. ⑤ Life: Laboratory in 1984.6 ~ August and August to October were observed twice, the life span of housefly is 1 to 2 months or more. ⑥ Fecundity: Six pairs of houseflies were observed. The female flies survived for 15-45 days and the total number of spawning eggs was 259-748. The female flies survived 15 days to lay eggs 4 times, survived 23 days to lay eggs 9 times, and survived 36 to 45 days to lay eggs 12 times, indicating that their fecundity is very strong.
