In this paper,researches were made on using 2% thiacloprid MSP to control the five main Chinese chestnut pests,including Dryocosmus kuriphilus,Dichocrocis punctiferalis Guenee,Curculio davidi Fairmaire,Characoma ruficirra Hampson and Cryllorhynobites ursulus Roelots.They belonged to the three kinds of pests,which were leaf pests,seed pests and branch tip pests.Using the method of spraying MSP among the mountains could achieve a lot of advantages,such as a lasting efficacy,reducing pesticide times,preventing many kinds of insects,low cost,and good effect.In these tests,different doses of 1.5 kg,3.0 kg and 4.5 kg per hectare were adopted and their average control effect ranged between 60.69% and 94.71%.
