摘要
试验对雌蛾设置 5个食物处理 ,定量地研究了成虫取食对棉铃虫雌蛾繁殖和寿命的影响。成虫取食对雌蛾寿命和产卵量均有显著影响 ,补充营养延长雌蛾寿命、提高产卵量 ,并且补充营养对产卵量的影响比其对寿命的影响更大。分析表明补充营养的作用在于提高雌蛾后期的存活率和产卵量 ,前期补充营养比后期补充营养具有更大的作用。雌蛾体重及其腹部干重受成虫食物和雌蛾日龄的双重影响。补充营养时雌蛾体重、腹部干重及其脂肪含量下降慢。补充营养可能是棉铃虫种群生态学中的一个重要因素 。
Effects of adult feeding on longevity and fecundity of the female Helicoverpa armigera (Hübner) were investigated quantitatively.Adult feeding had significant influence on both longevity and fecundity of cotton bollworm females.Females with supplementary food lived longer and deposited more eggs.With deterioration of adult food,fecundity was affected more than longevity.It is suggested that effects of supplementary food achieved by increasing female surviving and egg deposition during later stage,and food supplied during the early stage exerts greater effect than food supplied during later stage.Both adult food and female age significantly affected female fresh weight and dry weight of abdomens.Female fresh weight,dry weight and fat content of abdomens decreased less when the females were provided with supplementary food.Adult feeding may be an important factor in population ecology of the cotton bollworm,feeding during the early stage has an especially important role in female fitness.
