| Abstract | ||
| Field experiments were conducted to evaluate the efficiency of three different application techniques of three neonicotinoids insecticides against the Florida wax scale (FWS), Ceroplastes floridensis Comstock (Hemiptera: Coccidae) and its parasitoid, Coccophagus scutellaris (Dalman). The experiments were achieved in a private farm at Nobaria district, Beheira Governorate, Egypt during the spring seasons of 2019 and 2020. For ten weeks, the leaves samples were taken weekly. The results show that, among the different methods of insecticide applications, trunk injection technique achieved the highest reduction percentages for both adults and nymphs stages of FWS, followed by soil drench and finally foliar spray technique. However among different methods of application, trunk injection application maintained more C. scutellaris population (low reduction percentages %) than the two other methods (soil drench and foliar spray). In another hands, among insecticides, imidacloprid was the most effective and caused significant reduction in the population of the FWS and its parasitoid followed by acetamiprid and finally dinotefuran. Therefore, these results concluded that the trunk injection was the most appropriate technique for control C. floridensis and could be recommended in integrated pest management programs. | ||
