摘　　要：Comparative study was conducted on fresh and dried portions of Hyptis suaveolens plant, to control mosquito population, and determine which portion has the highest efficacy in killing the vector. The study was conducted in Nigeria Police Academy, Wudil, Kano State Nigeria. The result revealed that both portions of the test plant (Hyptis suaveolens) have toxic effect on mosquitoes. During the study, three (3) experimental units were established and nine (9) sub units were made, three within each of the major units at different locations within the study area. Mosquitoes were reared at all units and various quantities test plant (both fresh and dried portions) were introduced at different quantities and observed at different times of the day (Morning, Afternoon and Evening) within 24 hours in order to test their efficacy on mosquitoes. A total of two hundred and fifty three (253) death rate (DR) with a total % mortality rate (% M.R) of 217.9 mosquitoes were recorded from the three different experimental units with the highest % MR from the cadets hostels. There was a gradual overall mortality rate increase in every experimental unit as the quantity (concentration) of the test plant (Hyptis suaveolens) introduced into the units increased. More so, a resultant highest cumulative death rate of 119 was recorded in the evening. Comparatively, fresh portion of the test plant was more effective for killing the adult mosquitoes during the study. Statistically, it also shows that, there was a strong correlative relationship (r = 0.9832) between the quantity (concentration) of the test plant (H. suaveolens) and the death rate of mosquito vectors.Comparative study was conducted on fresh and dried portions of Hyptis suaveolens plant, to control mosquito population, and determine which portion has the highest efficacy in killing the vector.
