The Experiment of Using Bacillus thruringlensis Controlling Dendrolimus punctatus in Forests

    Graphical Abstract
    • Abstract
  • Some different consistencies of spraying Bacillus thruringlensis were tested in forests to control larvae of Dendrolimus punctatus.The rusult of the experiment showed that the consistence effects of 1 000,1 500,2 000,2 500 times all exceeded 80.6 percent.Among them,the effect of 1 500 times consistency was 96.5 Percent,being suitabl for controlling large areas for forestry production.
