摘要

未来几十年,人类人口将不断增长,对粮食的需求也将增加。因此,预计农业生产方式将会加强。其中就包括杀虫剂的使用。然而,杀虫剂威胁到蜜蜂,进而威胁到作物授粉,最终危及我们自身的粮食安全。这种进退两难的局面使得精确量化这些威胁的严重程度成为当务之急,这样我们才能改进我们的农业管理方法。通过系统回顾和荟萃分析,我们估算了施用杀虫剂对蜜蜂及其作物授粉服务的影响大小。结果表明,农药会使蜜蜂的存活率降低近五倍。即使蜜蜂存活下来,亚致死效应也会损害作物授粉。对蜜蜂群落及其作物授粉服务造成的后果可能不会立即显现,但从长远来看会被放大。最后,我们得出结论,保护作物周围的植被和尽量减少杀虫剂的使用是保护蜜蜂和确保作物授粉的关键。此外,采用病虫害综合防治(IPM)协议最终有助于解决这一问题,实现联合国可持续发展目标 2(零饥饿)。

Pesticides put our food security at risk by reducing bee survival almost five times

Pesticides put our food security at risk by reducing bee survival almost five times

In the coming decades, the human population will grow and demand more food. Therefore, agricultural practices are expected to be intensified. Among these practices is pesticide application. However, pesticides threaten bees and, thus, crop pollination, ultimately jeopardizing our own food security. This dilemma makes precisely quantifying the magnitude of these threats urgent, so we can improve our agricultural management practices. By conducting a systematic review followed by a meta-analysis, we estimated the effect sizes of pesticide application on bees and their crop pollination service. Our results show that pesticides reduce bee survival almost five times. Even when bees survive, sublethal effects can impair crop pollination. The consequences for bee communities and their crop pollination service might not be immediately evident but can be magnified in the long-term. Finally, we conclude that conserving the vegetation surrounding crops and minimizing pesticide use are key to protecting bees and ensuring crop pollination. Moreover, the adoption of integrated pest management (IPM) protocols can ultimately contribute to solving this problem and achieving UN’s sustainable Development Goal 2 (Zero Hunger).

期刊介绍: Apidologie is a peer-reviewed journal devoted to the biology of insects belonging to the superfamily Apoidea. Its range of coverage includes behavior, ecology, pollination, genetics, physiology, systematics, toxicology and pathology. Also accepted are papers on the rearing, exploitation and practical use of Apoidea and their products, as far as they make a clear contribution to the understanding of bee biology. Apidologie is an official publication of the Institut National de la Recherche Agronomique (INRA) and Deutscher Imkerbund E.V. (D.I.B.)
