She says these methods have been a major reason for the successes in malaria control in recent years. But because of those successes, scientists believe there has been less need to look at other ways to fight the disease. Fewer studies have been organized.
The World Health Organization has released guidelines, suggestions, on the use of LSM. Currently the organization does not support using larvicides in rural sub-Saharan Africa unless there are conditions that limit the habitats of mosquito larvae.瞄准早期发育的蚊子对任何防控规划来说似乎都是个有价值附加方法。但是露西·塔斯汀表示决定是否使用该方法并非易事。
她说这些方法是近年来疟疾防控取得成效的主要原因。但正因为取得的这些成效，科学家们就认为寻找其他抗击疟疾的方法已经没有那么必要。该方面的研究也少有进行。
世界卫生组织已在幼虫源管理方法使用上给出指导方针和建议，目前世卫组织并不支持在撒哈拉以南非洲乡村地区使用杀虫剂，除非该地有条件限制蚊子幼虫的栖息。
