摘要
中华虎凤蝶(Luehdorfia chinensis Leech)在杭州一年发生一代,以蛹越夏、越冬。1987—1989年,卵见于3月中旬至4月上、中旬,幼虫发生于4月上甸至5月中旬。在喂食25％蜂蜜水的条件下,雌、雄蝶寿命分别为12.9±5.82天和11.5±6.64天。卵2—35粒一堆,产在寄主叶背。卵期23.1±8.32天,卵发育起点温度7.68℃,有效积温111.40目度。幼虫期平均36.3天,全幼虫期取食叶面积25362.00±1820.68mm^2。蛹期307.5±4.65天。本文并就该蝶发生数量少的原因和应采取的保护措施作了简要讨论。
Luehdorfia chinensis has one generation a year in Hangzhou, Zhejiang Province. It over-summers and overwinters as pupae. Eggs appeared from mid March to early or mid April, and larvae from early April to mid May in 1987-1989. The life spans of the female and the male adults fed with 25% honey were 12.9±5.82 and 11.5±6.64 days, respectively.Females laid their eggs in groups of 2 to 35 on the underside of the leaves of their food plants. The egg stage lasted 23.1 ± 8.32 days. The developmental zero of the egg stage was 7.68℃ and effective temperature summation 111.40 day-degree. The mean larval stage was 36.3 days and the area of food consumption per larva throughout the whole larval stage was 25362.00±1820.68mm3. Pupae emerged as adults after 307.5 ±4.65 days.The cause for the rarity of the butterfly and the protective measure to be adopted are briefly discussed.
