Abstract
The farming practices adopted by producers affect the biodiversity of the entomofauna of vegetable crops.
Natural enemies of pests are a useful indicator of the stability of ecosystems.
Cropping systems and the use of inputs are part of agricultural practices that have a greater impact on the balance of biodiversity.
The objective of this study is to assess the impact of cropping systems and the inputs use on the biodiversity of natural enemies.
Surveys are being conducted among 144 market gardeners in Casamance, Senegal.
Insects found on crops are counted and larvae are monitored in the laboratory to determine parasitoids diversity.
The results show that polycultures and the use of urea increase the number of species of natural enemies.
On the other hand, monoculture and the use of biopesticides reduce the diversity of natural enemies.
The natural regulation of pests is increased when the diversity of natural enemies is important.
Cultural practices that favour insect diversity in agro-ecosystems strengthen the ecosystem balance and reduce pest damage to crops.
