Research on the Control of Didesm ococcus koreanus in Different DevelopmentStage at the Almond Orchard in Southern Xinjiang

  • Received Date: 2007-11-28
  • In order to exp lore new and effective measures to controlD idesm ococcus koreanus in different developmentalstages, according to the morphological characteristics and biological habitats ofD. koreanus in different developmentalstages, conventionalmeasures such as paring off bark and smearing, stem injection, and mist sp raying, were used totest the effect of controlling the larva with different instars. The results of test showed that: for the method, paring offbark and smearing and mist sp rayingwere the most feasible; for the effectiveness, (1) among the pesticides p rayed inthe first nymph instar, the vinegar2salt mixture had the best effect on the first instar larva, the effectiveness was ashigh as 90%; (2) by sp raying defoliant to control second instar larva, all the defoliantswith 3 different concentrationscould control the insects indirectly, and the effectivenesswas as high as 95%; (3) among the pesticides sp rayed inthe third instar, 95% alcohol agents had the best effect, the effectiveness could reach 90%; (4) among the smearingagents for controlling the third instar larva, 20% Imidaclop rid soluble liquid (1∶10 dilution) had better effect, whicheffectivenesswas 90%.
