Device for comprehensively determining hazard extent of pesticide for pollinating bees and determination method

用于综合测定农药对授粉蜂危害程度的装置及测定方法

Abstract

The invention belongs to the field of evaluation of harmful risks of bees, and particularly relates to a device for comprehensively determining a hazard extent of a pesticide for pollinating bees and a determination method. The device comprises a first box body and a second box body which are arranged indoors and are communicated by a passage; the bottom surface of the first box body is a gauze element; a paper piece and a food source are respectively arranged both inside and outside the gauze element; the paper piece is provided with a notch. The method comprises the following steps of: S1, spreading pollen on the paper piece, and spraying the pesticide to the paper piece and the food source; S2, communicating the second box body with one end of the passage, and blocking the other end of the passage by a cork; S3,placing the pollinating bees into the second box body, removing the cork, and communicating the other end of the passage with the first box body; S4, recording a death condition of the pollinating bees at regular time, and calculating the risk of the pesticide for survival of the pollinating bees by utilizing a survival risk analysis model. The device and the method well simulate a mode that the pollinating bees contact the pesticide in nature, and scientifically, systemically, reasonably and comprehensively evaluate the hazard of the pesticide for the pollinating bees.
本发明属于蜜蜂有害风险评估领域,尤其涉及一种用于综合测定农药对授粉蜂危害程度的装置及测定方法。该装置包括设于室内并通过通道相连通的第一箱体和第二箱体;第一箱体的底面为纱网,纱网的内外两侧分别设有纸片和食物源,纸片开设有缺口。该方法包括如下步骤:S1、在纸片上撒布花粉,向纸片和食物源上喷施农药;S2、将第二箱体与通道一端连通,并用软木塞堵塞通道另一端;S3、将授粉蜂放入第二箱体内,去掉软木塞,将通道另一端与第一箱体连通;S4、定时记录授粉蜂死亡情况,利用生存风险分析模型计算农药对授粉蜂生存的风险。该装置和方法较好模拟了授粉蜂在自然界接触农药的方式,科学、系统、合理的综合评估农药对授粉蜂的危害。
