摘要: 为了明确甘薯蚁象的发育起点温度和有效积温,在相对湿度60%,光周期12:12(L:D)的条件下,分别在20、23、25、28、31℃的光照培养箱中利用无虫薯块饲养甘薯蚁象,观察各虫态的发育历期。结果表明:在20、23、25、28、31℃的温度下甘薯蚁象均能完成生长发育,完成一个世代分别需要79.75、57.01、43.36、33.10、31.90天;卵、幼虫、蛹、成虫产卵前期及全生育期的发育起点温度为11.44、12.37、14.42、17.44、13.58℃,所需有效积温为118.07、233.42、78.41、72.87、515.77日·度。

Abstract: To determine its developmental threshold temperature and effective accumulated temperature, sweetpotato weevil (Cylas formicarius) were reared with sweetpotato root in the illumination incubator at 20, 23, 25, 28 and 31℃, under 60% RH and 12 h photophase. The results showed that the sweetpotato weevil could grow normally and complete one generation in 79.75, 57.01, 43.36, 33.10 and 31.90 d at 20, 23, 25, 28 and 31℃ respectively. The developmental threshold temperature of egg, larva, pupa, adult in pre-oviposition period and one generation was estimated to be 11.44, 12.37, 14.42, 17.44 and 13.58℃, respectively, and the effective accumulated temperature for their development was 118.07, 233.42, 78.41, 72.87 and 515.77 day degree, respectively.
