摘要
对甘蓝夜蛾赤眼蜂采用筛选和变温锻炼的4个组合处理连续饲养。20代后,在25℃,(75±5)%RH条件下检测质量指标。在饲喂蜂蜜水的条件下,经过筛选的处理雌蜂平均寿命和平均产卵量显著高于未经筛选处理。饲喂与不饲喂条件下测定处理组间差异显著性相同,不饲喂条件下各处理组平均寿命与产卵量相应降低。雌蜂后足胫节长度除恒温不筛选处理显著小于两筛选处理外,其他处理之间没有显著差异。恒温与变温处理之间各项指标都没有显著差异,但经过变温锻炼的处理多数质量指标明显高于恒温处理。
Trichogramma brassicae were reared on TBSitotroga cerealella eggs by four treatments. Quality of each treatment was assessed in 20th generation. Longevity and fecundity of treatments by selection of Trichogramma wasps were notably higher than treatments without selection. Results showed no notably difference between treatments with fluctuate temperature exercise and treatments without fluctuate temperature exercise, but treatments with fluctuate temperature exercise represented obvious longer longevity and higher fecundity than treatments without exercise.
