摘要

The evaluation of adverse effects of pesticides, pesticide adjuvants, and their combination on honeybees is hampered by a lack of colony-level bioassays reflecting productivity and survival over longer term exposure. In the present study, the joint toxicity of acetamiprid and co-applied pesticide adjuvants (N-methyl pyrrolidone [NMP], Silwet L-77, and Triton X-100) to honeybees was determined both in the laboratory and under semifield conditions. The 3 pesticide adjuvants caused no significant acute toxicity to honeybees by themselves; however, in the laboratory tests, they significantly increased the acute contact toxicity of acetamiprid to honeybees. For the semifield tests, in the T2 group (treatment with 5% acetamiprid soluble concentrate [SL] containing 10% Silwet L-77), the mortality of honeybees was significantly higher (p 0.05) than that of the blank control on the fourth day after application (DAA + 4), that of the T1 group (5% acetamiprid SL containing 10% NMP) on DAA + 4 and DAA + 7 (seventh day after application), and that of the T3 group (5% acetamiprid SL containing 10% Triton X-100) on DAA + 4. Furthermore, the flight intensity in the T2 group on DAA + 7, the colony intensity on DAA + 28 (28th day after application), and the mean areas covered by pupae on DAA + 15 (15th day after application) were significantly lower (p 0.05) than those of the blank control. Therefore, pesticide adjuvants may be important factors in increasing the toxicity of neonicotinoids to honeybees. Measures should be taken to manage the environmental risk of pesticide adjuvants during the process of formulation development and registration. Environ Toxicol Chem 2019;00:1-7. (c) 2019 SETAC
