Background: The use of chemical insecticides causes important damages to environment and human health and there is a need to search for alternative solutions. Objective: This study aims to investigate on the effect of Carica papaya latex gel on Anopheles gambiae sensu lato larvae tolerance in malaria vector control in Dogbo district in south-western Benin, West Africa. Methodology: Larvae of Anopheles gambiae s.l mosquitoes were collected from breeding sites using the dipping method in June 2020 during the rainy season in Dogbo district. A batch of 10 larvae of fourth instar were exposed to a mixture of Carica papaya latex gel with distilled water saturated with oxygen containing in each of five glass jars or test cups of same dimensions contained each 48 ml distilled water saturated with oxygen plus 2 ml of Carica papaya latex gel and one control jar containing no trace of Carica papaya latex gel. Larval mortality was recorded after 24 hours, 48 hours and 72hours exposure. Results: The results show that the use of Carica papaya latex gel causes full-grown Anopheles larvae to die by suffocation. After the application of this mixture, the larvae of four instars cannot breathe. The use of Carica papaya latex gel is effective method for disturbing the siphonal respiration of mosquito larvae. Conclusion: Carica papaya latex gel is effective method for mosquito larvae control.
