I. Laboratoy Rearing of the Aphidophagous Ladybeetle, Harmonia axyridis; Yolk Protein Production and Fecundity of the Summer Adult Female
무당벌레(Harmonis axyridis)의 사육 I;여름 성충의 난황단백질 생성 및 산란력
Abstract
The adult of the aphidophagous ladybeetle, Harmonia axyridis, was reared by feeding an artificial diet (chicken's 1iver:sugar = 5:2, v/w). The adult ladybeetle used was from pupae collected in the field in midJuly. Yolk protein production, fecundity and longevity of the adult female were checked under 3OoC, 16L:8D. Yolk proteins (Vg3 and Vg4) were detected from the hemolymph of the female 5 days after the emergence. One hundred pairs of female and male were reared separately. First oviposition started from 7 days afier the emergence and laid an average of 163.9k144.0 eggs during lifetime. Seventeen females did not lay eggs at all. Longevity of the female was 60.6k16.9 days. The application of a JH analog, methoprene (2.5 pg), caused the occurrence of yolk proteins in the hemolymph 1 day earlier than that of the control. Weekly application of 2.5 pg of methoprene induced 83.3% from the 30 females to lay eggs within 15 days after the emergence, while the control had 51% only. Methoprene made all females lay eggs, causing the increase in the fecundity. Though the longevity of the female was not effected by the weekly application of methoprene, one time excess dose (12.5 pg) caused high in mortality and low in fecundity.
