| 中文摘要: |
| 拟小食螨瓢虫是热带地区香蕉、番木瓜、橡胶和木薯等作物上有害叶螨的重要天敌。在室内条件下，以皮氏叶螨Tetranychus pierceii为食物，观察了不同温度(16℃, 20℃, 24℃, 28℃, 32℃)对拟小食螨瓢虫生长发育及繁殖的影响。结果表明：拟小食螨瓢虫卵、幼虫和蛹的历期在32℃下最短，分别为2.38, 4.26 和3.04 d；16℃时最长，分别为12.48, 25.10和16.12 d，雌成虫寿命在16℃时长达142.53 d，而在32℃时为95.46 d。世代发育起点温度和有效积温分别为13.29℃和227.63日度。成虫产卵量在28℃最高，达595.49粒/雌，在16℃最低，为125.05粒/雌。内禀增长率( rm )在32℃达到最大(0.2063)，而在16℃时最小(0.0342)。结果表明拟小食螨瓢虫有较好的高温耐受性，研究结果可为该瓢虫人工繁育的温度条件提供依据。 |
| 英文摘要: |
| Stethorus ( Allosstethorus ) parapauperculus is an important predator of tetranychid mites that occur in banana, papaya and rubber plantation in tropical area.The effects of temperature (16℃, 20℃, 24℃, 28℃ and 32℃) on development and reproduction of this coccinellid on Tetranychus pierceii were studied in laboratory experiments. The egg, larval and pupal duration of S.parapauperculus varies from 2.38, 4.26 and 2.60 d (32℃) to 12.48, 25.10 and 14.17 d (16℃), respectively. The longevity of adult females averaged 142.53 d at 16℃, but declined to 95.46 d at 32℃. The developmental threshold and effective accumulated temperatures for an entire generation were 12.82℃and 227.63 degree-day, respectively. The highest fecundity per female was observed at 28℃(595.49 eggs/female) and lowest at 16℃ (125.05 eggs/female). The intrinsic rate of increase (rm) was the highest at 32℃(0.2063) and lowest at 16℃(0.0342). It could be concluded that the relative high temperature was suitable for the development and reproduction of the ladybeetle. The implication of these results for mass rearing of Spa.rapauperculus was discussed |
