Acetonic extracts of Akanda was tested against different parameters of the life cycle of Cryptolestes pusillus. The lowest and highest oviposition rate (0.89±0.26 and 2.67±0.33 egg/female/day), hatching rate (14.67±0.53 % and 51.11±0.59 %), adult emergence (16.89 % and 40.89 %), and longevity (male 64.78±1.01day and 105.67±1.09 day) and female (69.56 ± 0.38 day and 113.22±0.57 day) were found in doses (552.413 and 163.678µgcm -2 ) whereas in control they were 4.89±0.35 egg/female/day,
more » ... %, 88.44 %, 156.11±1.37 day and 169.67±2.52 day respectively. But highest and lowest incubation period (7.33 ± 0.33 day and 4.89±0.35 day) and developmental period (71.67±0.60 and 39.89±0.26 days) occurred in the same doses and in control these are 4.11±0.26 egg/female/day and 33.44±0.50days.
