Biological characteristic and chemical control of Pseudalbara parvula

Abstract: Pseudalbara parvula , at the larval stage seriously damaged the leaves of Carya cathayensis in Lin,an City of Zhejiang Province , overwinters in pupae on earth surface under grass in the last ten days of September , emerging of the 1st ~ 3rd generation adults in June , July and august respectively , emerging of the overwintering adults in the last ten days of May the following year .The pest reproduces 4 generations with overlapping during a year in Lin,an .Its control could be made at the larval stage by spraying tree crowns with 1 500 ~ 2000 fold solution of fenzalerate 20EC or decamethrin 2.5EC , resulting in more than 95 % of the larvae being killed .The natural enemies such as Cissa erythrohyncha and Apanteles can play a good control role to the larvae after the 3rd generation in outbreak year .
