We develop a theory for host seeking decisions in mosquitoes that explicitly considers the tradeoffs mosquitoes face in allocation to somatic and gametic function. Specifically, we consider conditions under which mosquitoes should seek out nectar and blood hosts upon encountering host odours. Results from development of a dynamic model that considers free and crop energy states suggest that mosquitoes should seek out blood hosts under a wide variety of conditions but that decisions to seek nectar depends upon crop volume, concentration and free energy. This pattern arises because mosquitoes carrying large crop loads are constrained in their ability to obtain large blood meals due to space limitations in the abdomen. The predicted patterns of behaviour are supported by published observations of mosquito behaviour.
我们建立了一种关于蚊子寻找宿主决策的理论，该理论明确考虑了蚊子在分配到体细胞和配子功能时所面临的权衡。具体而言，我们考虑了蚊子在遇到宿主气味时应该寻找花蜜和血液宿主的条件。一个考虑了自由能和嗉囊能量状态的动态模型的发展结果表明，蚊子在各种各样的条件下都应该寻找血液宿主，但寻找花蜜的决策取决于嗉囊容量、浓度和自由能。这种模式的出现是因为携带大量嗉囊负荷的蚊子由于腹部空间限制，获取大量血餐的能力受到限制。预测的行为模式得到了已发表的蚊子行为观察结果的支持。
