The tested materials could be arranged according to their toxicity (initial kill) and residual effect on the field honeybee workers in the following ascending order: The initial kill of these insecticides were: 59.35%, 64.15% and 69.41% for Helban, Icton and Teleton, respectively. The residual effect of these insecticides were (32.02%, 40.82% and 40.56% after 14 days from the treatments, respectively. From the obtained results, it could be recommended to beekeepers to protect their colonies from the use of pesticides on cotton during at least the first 10 days of spraying- conduct spraying operations in coordination with the control field official and beekeepers in the early morning or end of the day, with the closure of the hives and put ventilation box or moved away from direct spray. in case of the time spraying | ||||
