We report the results of a large-scale (six orchards) and long-term (5-yr) study on seasonal population fluctuations fruit flies (Diptera Tephritidae) in mango (2005-2009) cashew (2007-2009) orchards Borgou Department, Benin.During five consecutive years fly monitoring, 25 tephritid species were captured including three Bactrocera, 11 Ceratitis, Dacus, which is represented by 2,138,150 specimens orchards. observed significant differences Bactrocera dorsalis (Hendel) counts between "high"...
In Benin cashew plantations, yields and nut quality are lost mainly as a result of insect pests. the present study, we investigated effectiveness African weaver ant Oecophylla longinoda biocontrol agent against Beninese 2-year yield were compared among: (i) trees with ants O. longinoda; (ii) where sugar-fed; (iii) integrated pest management (IPM) combined fruit fly bait spray; (iv) control receiving no measures. All treatments showed significantly higher than control, IPM treatment leading...
Prey capture and food scavenging activities of Oecophylla longinoda were monitored through regular weekly samplings during two consecutive years (2009–2010) in a large mango orchard the Borgou Department Benin, West Africa, main production area located Sudan agro-ecological zone. In both years, interspecific competition with other ants occurred mainly dry season (January to March) resulting increased captures Formicinae, Myrmicinae Ponerinae. More prey was caught rainy (end April end...
Abstract Species of the genus Dacus are important insect pests fruits and vegetables. Two species, punctatifrons Karsch vertebratus Bezzi, as well Bactrocera dorsalis (Hendel), were reared on a liquid artificial diet, carrot ( Daucus carota L.)‐based solid natural fruit host to assess suitability diet for small‐scale rearing these species. Egg hatch, pupal production, adult emergence F 1 productivity recorded evaluate performance three species each diet. hatch diets was more than 50% D. B. ,...
In Benin, damage caused by stem borers are a threat to rice production. The present study aimed at evaluating farmer knowledge of these pests in order find participative solutions for their monitoring and control rural areas. An agronomic survey was carried out with 151 producers the regions Zou, Collines Couffo where specimens samples were exhibited farmers identification. Field visits also undertaken observe knowledge. results recorded show that Benin have good main such Sesamia calamistis...
Weaver ants, Oecophylla spp., are known to positively affect cashew, Anacardium occidentale L., raw nut yield, but their effects on the kernels have not been reported. We compared size and proportion of marketable between nuts collected from trees with without ants. Raw weaver ants were 2.9% larger than control (i.e., ants), leading 14% higher kernels. On kernel: ratio damaged by formic acid was 4.8% lower nondamaged same trees. provided three benefits cashew production increasing yields,...
Weaver ants are used for biological control of insect pests in plantation crops. To obtain proper pest control, ant densities need to be high. Food availability and nesting facilities on host plants management practices may affect performance. In the present study, we tested effect two plant species (mango cashew) three different (ants only, fed with sugar combined soft chemical insecticide Spinosad) weaver Performance was assessed over a 22 month period, as an index value based number...
Oecophylla ants are appreciated for their control of pests in plantation crops.However, the ants´ nest building may have negative impacts on trees.In this study we tested effect ant densities and leaf performance mango trees.Trees were divided into three groups: trees without ants, with low high densities.Subsequently, total number leaves, proportion leaves used construction, tree growth was compared between these groups.The percentage nests 0.42-1.2% (mean = 0.7%±0.02)and not significantly...
The historic records of ants from Benin enumerate only 22 species. Our collections, with a primary focus on the mango farm ecosystem, Mangifera indica, have brought this total to 133 species which six were recorded before. specimens for all but been checked against type images Antweb.org. Twenty recognised as distinct and raised status, explanatory notes. Four appear be new will described elsewhere.
Les mouches Tephritides en général et particulièrement la mouche de mangue sont les principaux ravageurs dans vergers manguiers au Bénin. L’utilisation des parasitoïdes lutte contre ces dernières exige disposer préalable d’un élevage sain, stable à moindre coût leurs hôtes que mouches. A cet effet, l’aptitude pomme africaine, papaye banane servir comme substrat ponte milieu développement larvaire pour l’adaptation l’élevage mangue, Ceratitis cosyra C. anonae laboratoire a été évaluée. fruits...
