热带栖息地的特点是强烈的潮湿和干燥的季节，但季节性的成本和收益的社会性的影响在很大程度上是未知的热带昆虫。这是我们对社会生物学理解的一个重要空白，因为许多社会性蜜蜂和黄蜂都生活在热带地区。我们发现的证据表明，季节性影响的成本和收益的社会和孤独的行为在热带汗蜂Megalopta genalis.Productivity，无论是衡量每巢的育雏细胞生产，或每雌育雏细胞生产，是在旱季比雨季，可能反映花卉资源的可用性。每巢生产力更大的社会巢比孤独，但这种差异只在旱季显着。相反，人均生产力是更大的孤独比社会的巢穴，但同样只在旱季。巢失败率也较高，在雨季，虽然屋顶保护巢免受雨水并没有增加生存，这表明增加觅食的努力，面对资源下降，而不是潮湿本身导致巢失败。新发起的巢有较高的失败率比建立的巢，但这些都不受季节的影响。在繁殖基本停止后的雨季后期收集的社会巢穴表明，M。蜜蜂可以群居而不繁殖;这些蜜蜂可能一起等待，直到随后的旱季恢复供应。我们的研究结果表明，社会筑巢的生产力效益是最大的旱季，但保险为基础的社会筑巢的好处可能会更大的雨季。这表明，支持社会性的成本和收益在不同季节都是动态的，即使在热带系统中也是如此。
Tropical habitats are characterized by strong wet and dry seasons, but the effects of seasonality on the costs and benefit of sociality are largely unknown for tropical insects. This is an important gap in our understanding of sociobiology because many social bees and wasps are in the tropics. We found evidence of seasonal effects on the costs and benefits of social and solitary behavior in the tropical sweat beeMegalopta genalis.Productivity, whether measured as brood cell production per nest, or brood cell production per female, was greater in the dry season than the wet, likely reflecting floral resource availability. Per nest productivity was greater in social nests than solitary, but this difference was only significant in the dry season. Conversely, per capita productivity was greater in solitary than social nests, but again only in the dry season. Nest failure rates were also higher in the wet season, although roofs protecting nests from rain did not increase survival, suggesting that increased foraging effort in the face of declining resources rather than wetness per se led to nest failure. Newly initiated nests had higher failure rates than established nests, but these were not affected by season. Social nests collected late in the wet season after reproduction has largely ceased show thatM. genaliscan live in social groups without reproduction; these bees are likely waiting together until provisioning resumes in the subsequent dry season. Our results suggest that the productivity benefits of social nesting are greatest in the dry season, but that insurance-based benefits to social nesting may be greater in the wet season. This reveals that the costs and benefits underpinning sociality are dynamic across seasons, even in tropical systems.
