摘要
通过对美国白蛾的生活史、生活习性,各龄幼虫的鉴别特征、卵的发育温度、各龄幼虫的耐饥力及蛹重与携卵量关系的观察研究,提出了蛹重与携卵量关系的直线回归模型: Y=-580.07+5704.28x.
Based on the life cycle and behavior of Hyphantria cunea,the developmental zero temperature of its eggs,the morphological characteristics of larvae at various instar,and capability of enduring hungriness.the relations between the pupa weight and amount of eggs it carries is y=-450.47+4840X.
