目的了解泰山照山白枝叶粉末对家蝇产卵及其生长发育的影响。方法使用经照山白枝叶粉末处理的饲料喂养家蝇,进行实验室观察。结果照山白枝叶粉末对家蝇成虫有产卵忌避作用的最低有效浓度为4%,忌避作用有效期为60 h。质量分数为5%的照山白枝叶粉末能抑制家蝇幼虫的生长发育,使其发育迟缓,发育历期延长0.8 d左右。照山白枝叶粉末对家蝇蛹的孵化率无显著影响。结论照山白枝叶粉末对家蝇生长发育有抑制和产卵忌避作用,可降低其种群增长率。
Objective To understand the effect of white-leafed leaves of Taishanzhao Mountain on the spawning and growth of Musca domestica. Methods Houseflies were fed with feedstuffs of Chuan Shan white leaf and powder, and observed in laboratory. Results The minimum effective concentration of radix notoginseng foliar powder on adult eggs of Musca domestica was 4% and its repelling effect was 60 h. The white and green leaves powder with 5% (mass) fraction inhibited the growth and development of housefly larvae, delayed the development and prolonged the developmental period by 0.8 d. The photosynthetic white shoots and leaves had no significant effect on the hatching rate of housefly pupae. Conclusion Zhezhao white leaf and leaf powder can inhibit growth and evasion of housefly and reduce its population growth rate.
