温度对黄斑露尾(虫甲)生长发育及存活的影响

在适宜温度范围内,黄斑露尾(虫甲)的卵期、幼虫期、预蛹期、蛹期及全世代发育速率与温度呈直线相关;成虫产卵前期发育速率与温度呈“S”形曲线关系。卵期、幼虫期、预蛹期、蛹期和成虫产卵前期的发育起点温度和有效积温分别为12.3,10.2,12.1,11.5,17.6℃和19.6,124.9,22.9,81.5,20.2日度;全世代分别为11.8℃和279.6日度。在35℃时,各虫态的生长发育即受抑制,当40,45和50℃时,各虫态100％致死时间分别为48,24和6h;0℃时其幼虫、预蛹、蛹和成虫100％致死时间分别为5,15,0.75和10d.

Effect of Temperature on the Growth Developmentand Survive of Driedfruit Beetle (Carpophilus hemipterus L.)

This paper deals with systematically with the effect of temperature on the growth development and survive of Carpopkilus kemipterus (L,) in the laboratory. Results show that the growth rate of egg, larvae, pre-pupa, pupa stage and whole generation in the linear relation with temperature, and that of the pre-adult oviposting stage is in the rtSv curve relation .with suitable temperature. The determined initial temperature of egg, larvae, pre-pupa, pupa and pre-adult oviposting stage is 12.3, 10.2, 12.1, 11.5, and 17.6, respectively, while the effective accumulated temperature is 19.6, 124.9, 22.9, 81.5 and 20.2 degrees/day respectively. The initial temperature and effective accumulated temperature of the whole generation is 11.8 and 279.6 degrees/day respectively. The growth rate is inhibited at the temperature of 35.0 and the time of the 100% causing death at the temperature of 40.0, 45.0 and 50.0 is 48.24 and 6 hours respectively. Moreover, the time of the 100% causing death of larvae, pre-pupa, pupa and adult determined at the temperature of 0"C is 5, 15, 0.75 and 10 days respecively.
