摘要
通过室内按比例接种桃蚜无翅成蚜和卵形异绒螨初孵幼螨实验,采用多元单因素统计分析及多重比较表明,桃蚜被卵形异绒螨幼螨寄生后,其存活天数、繁殖天数和繁殖蚜量都出现大幅度降低,其降幅分别高达52％、70％和68％,而且各处理间的参数表现差异极显著。
Based on laboratory studies on larvae mites of Allothrombium ovatum of ectopara-sitize to alatae adult aphids of Myzus persicae in proportion and multivariate statistical analysis and multiple comparisons of these data, we found that parasitized M. persicae alatae had reduced survival time, reproductive time and reproductive number. Their maximum value of a decline in proportion were 52%,70% and 68%,and heterogeneity of parameters of every treatment were very significance.
