摘要
提出了核型多角体病毒（ＮＰＶ）对宿主幼虫平均致死速率［Ｖ（Ｔ）］与温度关系的数学模型，即式中Ｔ２５和Ｒ各为２９８．１５°Ｋ和８．３１４Ｊ·Ｋ－１·ｍｏｌ－１；ｐ（２５℃）、△ＨＡ、△ＨＨ和Ｔ１／２Ｈ为待定参数．该模型能很好地描述茶尺蠖ＮＰＶ感染各龄初幼虫后，平均致死速率与温度的关系；也适于描述美洲棉铃虫、大蜡螟和黎豆夜娥等ＮＰＶ对各自宿主幼虫的平均致死速率与温度的关系．
In this paper, the mathematical model describing the relationship of mean lethal rate V(T) of nuclear polyhedrosis virus (NPV) to its host larvae and temperature (T) is drawnas follows:of which, T25 and R are 298. 15°K and 8. 314J·K-1. mol-1; respectively, and P(25℃),△HA, △HH and T1/2H are unknown parameters. The model can well fit to describe therelationship of mean lethal rate of NPV from tea geometrid Ectropis obliqua hypulina toits host larvae infected with the virus at the beginning of each instar and temperature. Itis also fit to simulate the relationship between V(T) and T of Heliothis zea NPV, Calleria mellonella NPV and Anticarsia gemmatalis NPV to their host larvae, respectively.
