Botanical pesticides used in the control of insect pests of crops are nowadays an alternative to synthetic pesticides. This study evaluated the effectiveness of Top bio and Thevetia oil in the fight against cotton carpophagous pests. The experimental design was a Fisher Blocks with 6 treatments replicated 4 times. The six treatments were: the contr...

La préservation des prédateurs est fondamentale dans la gestion intégrée des ravageurs des cultures. Les insecticides botaniques sont de plus en plus utilisés compte tenu de leurs effets limités sur les auxiliaires. L’huile de Thevetia et un insecticide botanique à base de neem, Top bio, ont été testés à Gobé au Centre du Bénin pour l’évaluation de...

Market gardeners use synthetic pesticides in an unreasonable and uncontrolled way to protect their plots from insect pests. With the aim of finding alternative control methods to synthetic products, the efficacy of Cahew Nut Shell Liquid (CNSL) cold-applied Cahew Nut and three vegetable oils based on Tephrosia purpurea, Ricinus communis, and Thevet...

Le chou, Brassica oleracea L. (Capparales: Brassicaceae), est l’une des cultures les plus attaquées par un complexe de ravageurs dont Plutella xylostella L. (Lepidoptera: Plutellidea). L’objectif de cette étude était d’évaluer l’efficacité des huiles végétales et de la noix de cajou pour le contrôle de P. xylostella dans la production de chou. Une...

L’étude conduite dans les communes de Banikoara, Kandi, Gogounou et Ségbana au Nord-Est du Bénin a permis d’analyser les pratiques de gestion de la diversité variétale du niébé au sein de 97 ménages représentatifs de la zone d’étude. La méthodologie était basée sur des enquêtes individuelles au niveau ménage et des discussions de groupe au niveau v...

Defining effective strategies for combating crops insect pests requires to be well knowledgeable about their ecology and prevalence. This study identified on the one hand the major insect pests of biological cotton crops in the phytosanitary zones of Benin and one the other hand determined their seasonal evolution and evaluated their weight accordi...

Objectives: Insects are considered as the main vectors of Rice Yellow Mottle Virus (RYMV) in Africa. However, in Benin, little is known about the abundance and diversity of potential insect vectors of RYMV in rice fields to prevent and manage disease impact on rice production. Methodology and Results: The inventory of the potential insect vector...

Aphisgossypii is a phloem-feeding insect which remains one of the devastating pests of cotton crop. The present study assessed the effect of two different doses of cashew nut hot and cold extracts on aphids and their predators. The experimental design was a Fisher block design with six treatments each repeated four times. The treatments included: t...

The potential of four fungal biocontrol isolates (Trichoderma asperellum T-12, Pochonia chlamydosporia Pc-1, Kuklospora kentinensis BEN302, Aspergillus allahabadii BEN03) from West Africa to endophytically colonize tomato plants and provide in planta protection against root-knot nematodes (Meloidogyne spp.), was assessed in pots in the greenhouse....

MANAGEMENT OF ROOT-KNOT NEMATODES AFFECTING EGUSI MELON THROUGH APPLICATION OF TRICHODERMA ASPERELLUM AND NEEM SEED POWDER ABSTRACT The West African watermelon (Egusi melon), Citrullus mucosospermus Fursa, Cucurbitaceae, is one of the vegetable crops subjected to high pest and disease pressure, particularly root-knot nematodes. To reduce losses du...
Article
In the objective to find an alternative to endosulfan, the efficacy of profenofos and endosulfan has been studied in a complete randomized block design in experimentation station and in real environment. In station, the profenofos provides, in comparison with endosulfan, an equivalent control, and sometimes, a significantly higher (p < 0.001) contr...
Article
Objectifs: L’étude a pour objectif de réduire les doses de cyperméthrine-triazophos en culture cotonnière et d’apporter ou non les doses complémentaires en fonction du niveau d’infestation des ravageurs.Méthodologie et Résultats: La réduction de doses de cyperméthrine-triazophos a été étudiée sur la station de Gobé dans le Centre Bénin dans un disp...

This review focuses on insecticide resistance fitness cost and its consequences on resistance stability. Many cases of insecticide resistance are associated with fitness cost even though sometimes, resistance is not costly. The cost may be evidenced by different methods. Thus decrease of insecticide resistance in heterogeneous populations in the ab...
Article
The aim of this survey was to assess the costs of cypermethrin resistance in Helicoverpa armigera strains by using variation in their biological parameters such as fecundity, number of larval slough, development time, weight and survival at each stage of insect development in comparison with susceptible strains. AGB01 and AGB03 are the resistant st...

Pyrethroid resistance in Helicoverpa armigera (Hübner) field populations was investigated in Benin over several years by using third- and fourth-instar larval topicalbioassays. H. armigera was resistant to pyrethroids tested as cypermethrin, deltamethrin, bifenthrin, and fenvalerate. Pretreatment with piperonyl butoxide significantly decreased the...

Cotton is one of the most important cash crops in West Africa, contributing for more than half the income of some two million small-scale farmers cultivating on average about one hectare land. Cotton is being attacked by many pests, the cotton bollworm Helicoverpa armigera in particular, that developed high population densities in 1998 leading to y...
