Abstract
The objective of this study was to investigate
the impact of Moringa oleifera powders derived from different parts of
the plant on Callosobruchus maculatus in cowpea seeds under specific
environmental conditions. The experiment was conducted at a temperature of 29 ±
2°C and a relative humidity of 70 ± 5 R.H. To investigate the
effects of Moringa oleifera plant powders (leaf, stem, root, and flower)
on cowpea seeds infested with Callosobruchus maculatus adults a study
employed a fully randomized design. The results revealed significant variations
in the number of eggs laid, hatched eggs, and emerged adults among the
different treatments (P ≤ 0.05). The application of 0.5 g of Moringa
oleifera flower powder resulted in the lowest average number of eggs
(7.30), which differed significantly from the control group that did not use
any plant product. Additionally, the control group exhibited the highest number
of hatched eggs (44.33), the mean number of hatched eggs displayed a
considerable disparty (3.20 and 0.35) observed when the application of leaf and
flower powders was done, separately (P ≤ 0.05). When stem and leaf powders were
applied, the total developmental period was significantly reduced to 16.7 days
and 18.9 days, respectively, compared to the control group's period of 24.8
days. Within the first 24 hours of insect infestation, the mortality
percentages were 88% and 74%. These findings imply that Moringa oleifera
flower powder has the potential to be used as a bio-insecticide for controlling
Callosobruchus maculatus in stored cowpea seeds.
