资源缺口是熊蜂在建立蜂群阶段面临的最大威胁

支持野生传粉昆虫减少的一种常见管理干预措施是 "传粉昆虫种植"。然而，尽管多年来传粉昆虫一直被纳入保护计划，但全球传粉昆虫数量仍在持续减少。我们利用基于代理的 BEE-STEWARD 模型和两个示例物种：Bombus terrestris (L. 1758) 和 B. pascuorum (Scopoli, 1763)（膜翅目：鳞翅目），探索了一年中什么时候大黄蜂的资源需求最大，以及这与蜂群组成（卵、幼虫、蛹和成虫数量）的季节性变化有何关系。然后，我们研究了为期两周的全年资源匮乏期的影响。最后，我们将探讨用早春开花的草本植物或树木来提高蜂群的存活率和蜂王产量会产生怎样的变化。在英国，熊蜂在三月至四月的飞行高峰期之前有一个以前未被充分认识到的 "饥饿缺口"，其驱动因素是幼虫对蛋白质和蜂群体温调节的需求，而不是成蜂的数量。在此期间，如果饲料供应出现两周的缺口，子蜂王的产量就会下降 50%-87%。在模型中加入早花种对蜂群存活率和子蜂王产量有显著的长期积极影响。国家和国际保护计划中的授粉者种植措施需要包括在目标社会授粉者物种的成虫在田间显现前 1 个月，即幼虫主宰蜂群期间开花的植物。这种方法有可能提高蜂群存活率和蜂王产量，有助于阻止和扭转全球授粉者减少的趋势。
