Evaluation of the effect of the use of anti-insect nets on vegetable production in southern Benin

The objective of this research is to assess the effects of the use of insect nets in vegetable production. To achieve this goal, data were collected in four departments of southern Benin (Mono, Couffo, Ouémé and Plateau) using an interview guide and a structured questionnaire. A total of 223 producers chosen at random from these areas where the CRSP Horticulture Project is located were surveyed. The results of the study show that growers using insect nets have not given up using chemical pesticides. However, a significant reduction in treatment frequencies was recorded in the nursery and after transplanting for most of the pesticides identified. Similarly, a significant reduction (more than 60.0%) in pest attacks (Helicoverpa armigera, Hellula undalis, Plutella xylostella, Bemisia tabaci and cochineals) was recorded among producers using anti-insect nets at 5%. These results involve that it is necessary to sensitize farmers to the use of nets to protect plants. This will significantly reduce pest attacks and reduce the use of pesticides in production.
