菲律宾实蝇Bactrocera(Bactrocera)philippinensis(Drew & Hancock)是重要的检疫性有害生物,严重危害芒果Mangifera indica L.、木瓜Carica papayaL.和菠萝蜜Artocarpus heterophyllus Lam.等水果。本文在室内实验条件下对菲律宾实蝇生物学特性进行了较为系统的研究。结果表明:菲律宾实蝇在6～18h羽化率达93.93%。成虫活动、寿命、交配和产卵与温度、光照密切相关。补充营养能显著延长成虫寿命。菲律宾实蝇生长、发育和繁殖的适宜温度为25～30℃。25℃和30℃时平均产卵量分别为627.35粒和652.57粒。发育起点温度和世代有效积温分别为14.31℃和450.43日·度。温度与发育历期呈显著的负相关(r=-0.9005)。本研究为菲律宾实蝇的检疫处理和田间防治技术研究提供了重要的基础资料。
Philippine fruit fly Bactrocera (Bactrocera) philippinensis (Drew & Hancock) is an important quarantine pest, severely endangered mango Mangifera indica L., papaya Carica papaya L. and jackfruit Artocarpus heterophyllus Lam. And other fruits. In this paper, the biological characteristics of fruit flies in the Philippines were systematically studied under laboratory conditions. The results showed that the fecundity rate of fruit flies in the Philippines was 93.93% from 6 to 18 hours. Adult activity, life expectancy, mating and oviposition are closely related to temperature and light. Supplementary nutrition can significantly extend adult life expectancy. The optimum temperature for growth, development and reproduction of fruit fly in the Philippines is 25 ~ 30 ℃. The average fecundity at 25 ℃ and 30 ℃ was 627.35 and 652.57 respectively. Developmental starting temperature and generation effective accumulated temperature were 14.31 ℃ and 450. 43 日 · 度. There was a significant negative correlation between temperature and developmental duration (r = -0.9005). This study provides important basic information for quarantine treatment and field control technology of fruit flies in the Philippines.
