The Efficacy Of Pepper (Capsicum Annum) In The Control Of Cowpea Weevil (Callosobruchus Maculatus) In Cowpea (Vigna Unguiculata) During Storage
ABSTRACT
The experiment lasted for a period of 3 weeks.
The insecticidal property of Capsicum annum against Callosobruchus muculatus (
cowpea weevil) was investigated in the laboratory. Mortality rate of cowpea
weevil was tested using Capsicum annum at different grams ranging from lg, 1.5g
and 2g of the powder against 20 adult cowpea weevils. The experiment was
carried out in replicates. The percentage mortality rates were 17.33 (86.65%),
18.00 (90.00%) and 19.69 (98.35%) were observed after 2 weeks of subjecting
tlie adult cowpea weevil to Capsicum annum of lg, 1.5g and 2g. The efficacy of
the plant powders on the emergence rate was also investigated within a period
of 3 weeks. The values obtained within these weeks were analyzed in means,
standard deviation and ANOV A. The mean and standard deviation values for plant
powder were (28.67) (±1.155), (2.33) (±0.577) and (0.33) (±0.577). The values
showe»significant difference at (P<0.05). It was observed that the powders
reduced the emergence rate of weevil. Therefore, the plant powders should be
used to protect stored cowpea from pest infestation.
