Abstract
The cultivation of okra (Abelmoschus
esculentus) has many constraints, including those related to bio-aggressors
that are often eliminated by chemical pesticides that are dangerous for the
environment, human health and cause resistance in insects. To avoid the
consequences of pesticide use, farmers are using pesticides. It is in this
context that this study was proposed and has as its general objective to know
the entomological fauna on the cultivation of okra and to determine the effect
of neem and garlic-based bio-pesticides on the incidence of these insects on
okra plants. To this end, an experimental system consisting of nine [9] beds
11 m long and 1.10 m wide with paths 50 cm in length was set up. Of the nine [9]
beds, three were treated with a neem-based bio-pesticide, three with a
garlic-based bio-pesticide, and the remaining three represented the control.
Mainly 3591 individuals, divided into six [6] orders (Orthoptera,
Hemiptera, Hymenoptera, Lepidoptera, Diptera and Coleoptera), seven [7]
families (Ainidae, Coccidae, Aphidoidea, Fourmicidae, Geometridae, Aleyrodidae,
Coccinellidae) and eight [8] species, have been identified in the
experimental area. Analysis of the results shows that Aphis gossypii, Pseudococcus
viburni and Formica sp. were present consistently with a frequency
of occurrence of 100% and incidences of 30%, 42% and 35% respectively. Analysis
of the results shows that Aphis gossypii, Pseudococcus viburni
and Formica sp. were present consistently with a frequency of occurrence of 100% and
incidences of 30%, 42% and 35% respectively. The effect of the treatment is
significant on leaf attack; there are fewer leaves attacked on plots treated
with garlic solution. Results of the treatment on the weight of the attacked
fruits as well as on the yield of the production were not significant.
