不同食料饲养斜纹夜蛾对其生长发育的影响

Effects of Different Foodstuff on Growth and Development of Prodenia litura

为了对进一步研究斜纹夜蛾种群动态的预测预报奠定基础,研究了斜纹夜蛾幼虫取食木薯叶、芦笋叶和人工饲料3种食料对其生长发育和繁殖能力的影响。结果表明:斜纹夜蛾幼虫发育历期、蛹重、存活率和成虫繁殖力均以取食芦笋的表现最好,其次是取食木薯叶的,取食人工饲料的最差。经种群趋势指数分析,3种食料条件下,斜纹夜蛾种群数量均呈增长趋势,以芦笋组最优。

In order to lay a certain foundation for further studying on P. litura population dynamic prediction, growth and development, adult fecundity of P. litura were investigated when the larvae were fed with cassava leaves, asparagus leaf and artificial diet. Results： The development period, pupa weight, survival rate and fecundity of P. litura larvae fed with asparagus was the best, followed by cassava leaves, the worst was artificial diet. Through the population trend index analysis of the three diets, population of P. litura was on the rise, and asparagus group was the best.
