Abstract: Meteorological regime is thought to be a key factor that has an important influence on the occurring density of the population of Pelochrista sp., an insect damages the eucalyptus.The occurrence culmination of the insect comes up around May, which causes heavy losses to juvenile eucalyptus plantation planted in the concurrent year.Strategies developed for minmizing the losses include manipulation of the planting date after May for the least insect occurrence purposes and application of insect-resistant species of eucalyptus as well as spraying of 25% Dimilin Ⅲ in dilution of 1500~3000 times and rhizosphere application of 3% granular carbofuran 3~5 grams per stock.
