A study was conducted on the assessment of seed extract of Jatropha curcas for the control of Callosobruchus maculates. Jatropha curcas seed extract was obtained by using methanol. The plant extract was prepared into different concentrations of 1w/v, 2w/v, 3w/v and were compared for their relative bioactivity against Callosobruchus maculates adult and larva in the laboratory at temperature, 29OC and the parameters assessed were mortality and rate of oviposition of Callosobruchus maculates on the treated beans. The result showed that the mortality of Callosobruchus maculates increased with exposure period and concentration of extracts and the rate of oviposition decreased seriously with an increase in concentration level. ...
