A COMPUTER SIMULATION MODEL FOR EGG AND LARVAE STAGES OF COTTON BOLLWORM
棉铃虫卵及幼虫阶段动态的一个计算机模型

This paper presents a computer simulation model for egg and larvae stages of cotton bollworm (Heliothis armigera) . This model is essentially a life table model according to the logical relationship of development and survival . The input information of the model is the amount of the white egg day by day. And it's output involves the population size of every stage and age. The simulation method is as follows: white egg when i = 0; j = 1where n(t)i,j, is the insect amount that in the i th stage and j th age ...
