Anopheles mosquitoes are the most important vectors among the arthropods. Human malaria is transmitted through the bites of female Anopheles mosquitoes. It is estimated that malaria is responsible for 627000 deaths globally. The usage of natural products such as larvicides is considered as a significant method for mosquito control. Natural products have beneficial advantages including efficacy, degradability and non-toxic effects on non-target organisms. Based on laboratory and field experiences, descriptive studies or reports, six categories are considered for larvicidal activity of natural products derived from plantsincluding extremely active, highly active, active, moderately active, slightly active and non active. This guidance suggests the likely larvicidal activity of plant essential oils based on the LC50 value. We consider natural products derived from plants extremely active when its LC50 is up to 1, highly active when its LC50 is between 1-5, active when its LC50 is between 5-50, moderately active when its LC50 is between 50-100, slightly active when its LC50 is between 100-200 and non-active when its LC50 is more than 200. It seems three classes extremely active, highly active and active are required more attention, while there is no priority of research for the rest of categories.
