| Abstract: | Objective] Insecticides were screened out for controlling Acantholyda posticalis.Method] The field efficacy of different insecticides on the larvae ofA.posticalis was studied by plot test.Result] After 72 hours,the best control effects of thiacloprid against A.posticalis of the 1st instar larvae were between 94.7％ and 96.9％.For the 2nd instar larvae,the best control effects of thiacloprid against A.posticalis were between 89.7％ and 93.0％.For the 3rd instar larvae,the best control effects of thiacloprid against A.posticalis were between 88.9％ and 91.0％.Conclusion] Thiacloprid can be applied for controlling the larvae of A.posticalis.And the best control period of A.posticalis is the 1 st instar larvae. |
