STUDIES ON BIOLOGICAL CHARACTERISTIC OF LYMANTRIA DISPAR
AND THE TEST MODEL ABOUT IT'S LARVAE OCCURRENCE PERIOD
摘要
Abstract
Lymantria dispar mainly harm the persimmon trees in Shandong Province.They've occured much and caused enormous losses in our production for years.The prevention and cure of this kind moths' crucial period is the larvae's common incubation.This article takes advantage of the relation between the mean dayly temperature after late March and the persimmon sprouts' growing length and the incubation rate of the larvaes.Two forecast models have been set up to report the larvaes'occurrence period,Yi=12.0742X1=139.1908 and Yi=1.1115X2+0.6642.Tests and verifies of production living exampls have conducted,and the accuracy of the test is over 94 percent.关键词
