| Abstract: | Pseudaulacaspis pentagona Targioni has two or three generations each year on apricot trees grown in greenhouse in Zhengzhou area,Henan province. Practice proved the best time for insecticide spraying was at the majority eggs hatching and nymphae spreading stage. Avermectin + chlorpyrifos 24EC 160-240 mg/L,or avermectin + mineral oil 24.5EC 163.3 mg/L was efficient and safe for spraying in early and middle April. When at the second nymphae spreading stage, Avermectin + chlorpyrifos 24EC 160-240 mg/L or chlorpyrifos 48EC 480 mg/L could be used for control. When the trees are in dormancy,methidathion 40EC 500-666.7 mg/L would be recommended. |
