在试验条件下用桃蚜及植物花粉饲养南方小花蝽,通过对南方小花蝽取食桃蚜及植物花粉后的体重的增长以及同时段内对桃蚜及植物花粉减少的量的测定, 得到南方小花蝽取食两种食物后的发育速率及其生态效率。结果表明,桃蚜可以较好地满足南方小花蝽正常生长发育所需的营养,南方小花蝽取食桃蚜后的生态效率明显高于取食植物花粉的。通过本论文的研究有助于更好地认识南方小花蝽取食不同食物后的生长发育规律,从而更好地进行南方小花蝽的室内人工大量饲养,使南方小花蝽作为桃园及棉田害虫种群综合治理中的重要组成部分发挥其应有的作用。
Under the experimental conditions, peach aphid and plant pollen were used to feed S. japonicus, and the weight gain of M. avenae and plant pollens after their feeding on S. aurantii and the determination of the amount of pollens of peach aphid and plant during the same period were measured to obtain southern Developmental rate and ecological efficiency of two species of food bugs after feeding on. The results showed that Myzus persicae could better meet the needs of the normal growth and development of Myrmicidae, and the ecological efficiency of Myzus persicae was higher than that of the plant pollens. Through the research in this paper, it is helpful to better understand the law of growth and development after feeding different foodstuffs in southern China, so as to better carry on large-scale indoor artificial feeding of S. japonicus and to make S. japonicus integrated as pest population in Taoyuan and cotton fields Important components of governance play their due role.
