- Abstract: Background: Camphor has a long-term application history in the control of insect pests and their mixture with kerosene is not an exception in the control of mosquitoes. Objectives: Due to differences in larval biology and positioning in breeding sites, this study was designed to reassess the potency of camphor mixed with kerosene against the emergence of Anopheles mosquitoes in order to ascertain that efficacy of a treatment may not differ greatly with different mosquito species. Methodology: Larvae and pupae of Anopheles mosquitoes were collected from Ndokwa West Area of Delta State, Nigeria using standard World Health Organization method and left to acclimatize for 6 h in the Insectary before exposure. Mosquitoes were confirmed as Anopheles gambiae. Camphor (2 g) and its mixture with kerosene in equal ratio were introduced into 100, 200, and 400 mL of water which equated 0.02%, 0.01%, and 0.005%, respectively. Anopheles mosquitoes exposed to only water served as control for the experiment. Twenty larvae and pupae in their third stage of larval development was first sorted into 1000 mL glass beaker and then introduced into various treatment concentrations in 3 replicates. Results: Highest mortality was recorded in larvae exposed to 0.02% of camphor mixed with kerosene. Pupae exposed to same concentration compared favorably. Lethal dosage (LD50 and LD95) of camphor exposed to Anopheles larvae and pupae ranged from 0.002% to 0.004% and 0.021% to 0.491%, respectively. More so, values were 0.002% and range from 0.010% to 0.021% in camphor mixed with kerosene, respectively. Conclusion: Therefore, the intensification in the use of camphor mixed with kerosene among the population in mosquito breeding sites would reduce the mosquito biting activities and diseases in the locality.
