摘  要:
本文对烟仓麦蛾茧蜂的生物学和生态学特性进行了研究。结果表明,麦蛾茧蜂在烟仓的消长有2个高峰期,第1个高峰期发生在4月份,第2个高峰期发生在10月份。温度(T)对麦蛾茧蜂的寄生率(P)、卵孵化率(H)、成蜂的产卵量(L)和茧的羽化率(C)影响显著,其关系式可分别表达为:P=—352.67+32.54T—0.61T~2、H=—381.82+35.79T—0.67T~2、L=—82.05+16.32T+0.27T~2、C=—119.18+16.52T—0.32T~2。在不同的营养中,5%蜂蜜水对麦蛾茧蜂的影响最为显著。在同一温度下,麦蛾茧蜂成蜂的发育历期最长,其次是蛹,幼虫的历期高于卵的历期;对于同一虫态,随着温度的升高,其发育历期逐渐缩短。麦蛾茧蜂成蜂的发育起点最低,但其所需的有效积温最高;幼虫的发育起点温度最高;卵的有效积温最低。

摘  要:
The present paper deals with the biology and ecology of Habrobracon hebetor (Say), one of the most important natural enemies parasitizing the larvae of Ephestia elutella Hübner, Corcyra cephalonica Staint, Sitotroga cerealella Oliver, Anagasta kuhniella Zellen and Plodia inter punctella Hübner in tobacco storehouse. The dynamics of the braconid wasp shows two peaks, one of which occurs in April, and another in October. The regression equations between temperature (T) and the rate of parasite (P), of hatching (H), of egg—laying (L) and of emergence (C) can be determined as:P=—352. 67+32. 54T—0. 61T~2, H=—381. 82+35. 79T—0. 67T~2, L=—82. 05+16. 32T+0. 27T~2 and C=—119. 18+16. 52T—0. 32T~2, respectively. 5% honey shows prominent impact on the wasp among the different nutriments. The development duration of adult wasp is the longest among the different stages under the same temperature. The development duration of the wasp decreased when the temperature increased under the same stage.
