A PRELIMINARY REPORT ON THE CONTROL OF SELEPA CELTIS MOORE WITH SEVERAL INSECTICIDES

  • Received Date: 1989-08-29
  • Selepa celtis Moore is a pest of Duabanga grandiflora and other species of trees and crops. In the field, its generations are overlapping. It has about 7~8 generations each year in Guangzhou, Guangdong Province. The females lay their eggs in masses of 30~100 on the leaves where the larvae eat the leaves of the trees, but they are skeletonizers throughout their larval life. There are 4~5 larval instars. When mature, they drop to the ground spinning their cocoons to pupate. During summer and fall, the egg, larval and pupal stages last 6~9, 13~19 and 8~13 days, respectively.The effective control of larvae are spraying with Dipterex, Dichlorvos, Malathion,Fenitrothion, Carbaryl or Pyrethrins, or destroying infested leaves and them.

  • 1. South China Agricultural University

Abstract: Selepa celtis Moore is a pest of Duabanga grandiflora and other species of trees and crops. In the field, its generations are overlapping. It has about 7~8 generations each year in Guangzhou, Guangdong Province. The females lay their eggs in masses of 30~100 on the leaves where the larvae eat the leaves of the trees, but they are skeletonizers throughout their larval life. There are 4~5 larval instars. When mature, they drop to the ground spinning their cocoons to pupate. During summer and fall, the egg, larval and pupal stages last 6~9, 13~19 and 8~13 days, respectively.The effective control of larvae are spraying with Dipterex, Dichlorvos, Malathion,Fenitrothion, Carbaryl or Pyrethrins, or destroying infested leaves and them.
