딸기용 농약의 꿀벌에 대한 급성독성 및 엽상잔류독성

다국어 초록 (Multilingual Abstract)

Lack of honey bee toxicity data for most pesticide products used for strawberry restricts to predict the adverse effects to foraging honey bee after treatment of pesticide in plastic house. This study was conducted to evaluate the actual risk of worker honey bees (Apis mellifera L.) through acute contact toxicity test， acute oral toxicity test and toxicity of residues on foliage test with 21 pesticide products. The mortality of honeybee sprayed with 6 pesticides including dichlofluanid WP showed significantly different from control at recommended application rate in acute contact toxicity test at 24 hours after treatment. Fenpropathrin EC and milbemectin EC treatment groups showed more than 25% mortalities at recommended application rate in acute oral toxicity test. In toxicity of residues on foliage test， only fenpropathrin EC treatment group showed more than 25% mortalities at 10 days after treatment at recommended application rate. It was concluded that the most toxic route to exposure for honey bee is direct contact exposure to sprayed pesticides. Safety interval for honey bee was established by concerning the results of these tests.
