| Abstract | ||||
| Mulberry trees suffer from many pests’ infestation. To control these pests some natural materials such as Techno Oil and Top 9 and some other chemicals such as Mospilan® and Chinook® could be used. Mulberry trees, Morus nigra were treated with three different concentrations of each of Chinook, Techno Oil® and Top 9® to reduce infestation with Icerya sp. and Ferrisia virgate. A high reduction rate of more than 90% occurred when using these pesticides. On the other hand, the corrected mortality of larvae of mulberry silkworms was 93.3%, 0.0% and 6.7% after 8 days of treatment with Chinook, Techno Oil and Top 9, respectively. When treating mulberry trees Morus alba with two different concentrations of each of the pesticides; Mospilan and Techno Oil against whitefly, the average rate of reduction in infestation was 100% and 94.94%, respectively. The corrected mortality of larvae of mulberry silkworms was 100% and 0.0% after 8 days of treatment with Mospilan and Techno Oil, respectively. This study suggests that natural materials could be used safely -instead of chemical pesticides- to reduce pest population without affecting the life of silkworm larvae or cocoon properties. | ||||
