Determination of the effect of some pesticides on honey bees

Although the bee deaths that started in 2006 have passed for a long time, no solution has been found and even bee deaths have started to increase again in recent years. The end of winter and spring months are periods when bee deaths are seen intensely. When these periods are examined, it can be seen that many factors (disease-harmfulness, hunger, cold, etc.) cause bee deaths. One of these factors is the pesticides used in springtime in the wintering region. In this study, the effects of pesticides, which are commonly used against factors damaging agricultural crops grown in regions where bee deaths is high, on the body motor movements of the bees are investigated. The most commonly used product used for agricultural combat in pesticides used in our study and the label dose (recommended dose) used for this product was fed twice with the label dose and half by oral gavage, after 1, 4 and 24 hours, the bees were checked and some of the body parts (antenna, leg, abdomen and mouth parts) were rated according to motor movements. As a result of the study, pesticides affecting body motor movements of bees are listed as Chlorpyrifos-Ethyl, Imidacloprid, Deltamethrin, Thiacloprid, Acetamiprid, Abamectin and Tau-fluvalinate active substances from high to low. Spirodiclofen, Glyphosate Potassium Salt, and Penconazole active substance chemicals arranged in the same group with control and did not changed their body motor movements.
