Field Control Experiments and Toxicity of 6 Pesticides to Asian Citrus Psylla(Diaphorina citri Kuwayama)
Citrus psylla (Diaphorina citri) has become the most important pest in Huanglongbing (HLB) areas. Up to now; the assay was yet not reported. By means of dipping, the laboratory toxicity of 6 pesticides to adult psylla was conducted out in 2008. The LC<,50> of carbosulfan, phenthoate,bifenthrin,imidacloprid, quinalphos,Piri-miphos-methyl was 4.1mg/kg, 44.3 mg/kg, 44.3 mg/kg, 60.1 mg/kg, 73.5 mg/kg, 192.8 mg/kg, respectively. Af-ter treating of 24 h, 3d and 7 d, the adult psyUid field control efficiency of bifenthrin plus azone 12.5 mg (a.i)/kg was all 100%. the adult psyllid control efficiency of phenthoate 333 mg(a.i)/kg,quinalphos 250 mg(a.i)/kg, carbo-suffan plus azone 200(a.i)/kg was all over than 95%, while that of pirimiphos-methyl 500 mg(a.i)/kg less 80%. The adult psyllid field control efficiency of carbosulfan plus azone 200(a.i)/kg was better than that of carbosul-fan 250(a.i)/kg.
