尽管有效的长效驱虫蚊帐和/或室内滞留喷洒的覆盖率很高，但疟疾的残留传播可能会持续下去，因为许多病媒蚊子通过以动物为食、在户外觅食、在户外休息或在进入房屋后迅速离开来躲避它们。然而，许多这些行为使病媒对室内滞留喷雾杀虫剂和长效驱虫蚊帐的控制具有抵抗力，但也使它们容易受到一些新出现的替代干预措施的影响。此外，针对蚊子偏好行为的病媒控制措施往往迫使它们表现出以前罕见的其他行为，然后可以用这些补充性的新干预措施来针对这些行为。例如，针对以往主要在室内以人类为食的病媒部署长效驱虫蚊帐，通常会导致通过在室外以人类和动物为食而存活的残余种群持续传播，然后它们可能分别成为气相杀虫剂和兽用杀虫剂的目标。因此，虽然蚊子表现出替代行为的能力限制了长效驱虫蚊帐和室内滞留喷雾杀虫剂的影响，但它也为部署补充性额外方法创造了可衡量的和前所未有的机会，否则这些方法将无效。现在终于有了更多样化的病媒控制方法，国家疟疾控制方案应充分利用已确立的调查成蚊行为的昆虫学实地技术，合理和适应性地规划新的机会，以有效利用这些技术。
Residual malaria transmission can persist despite high coverage with effective long-lasting insecticidal nets (LLINs) and/or indoor residual spraying (IRS), because many vector mosquitoes evade them by feeding on animals, feeding outdoors, resting outdoors or rapidly exiting from houses after entering them. However, many of these behaviours that render vectors resilient to control with IRS and LLINs also make them vulnerable to some emerging new alternative interventions. Furthermore, vector control measures targeting preferred behaviours of mosquitoes often force them to express previously rare alternative behaviours, which can then be targeted with these complementary new interventions. For example, deployment of LLINs against vectors that historically fed predominantly indoors on humans typically results in persisting transmission by residual populations that survive by feeding outdoors on humans and animals, where they may then be targeted with vapour-phase insecticides and veterinary insecticides, respectively. So while the ability of mosquitoes to express alternative behaviours limits the impact of LLINs and IRS, it also creates measurable and unprecedented opportunities for deploying complementary additional approaches that would otherwise be ineffective. Now that more diverse vector control methods are finally becoming available, well-established entomological field techniques for surveying adult mosquito behaviours should be fully exploited by national malaria control programmes, to rationally and adaptively map out new opportunities for their effective deployment.
