Abstract： The control effects of several new pesticides on Calacarus carinatus were determined by the pot and laboratory experiments. The results show that the control efficacies of 99% mineral oil  emulsion （100～200 times） and 0.6% matrine aqueous solution （1 000～2 000 times） and 0.3% azadirachtin  aqueous solution （500 times） and 1.5% pyrethrin aqueous emulsion （500 times） were all above 90% on the 7th day after spray. The mineral oil and the three plant pesticides tested had good control effects on Calacarus carinatus.
