The infectivity and pathogenicity of three native entomopathogenic nematodes (Heterorhabditis (HNI 0100 and sp-CIAT) and Steinernema (SNI 0198)) were evaluated in third instar larvae of Phyllophaga menetriesi (Blanchard) under laboratory conditions. Concentrations of 7000 and 13,000 infective juv...

Chemical exclusion of predators with permethrin was used to test the effectiveness of the phytoseiid predator Amblyseius limonicus Garman and McGregor and a complex of minor predators in the biological control of tetranychid (Mononychellus spp., Tetranychus spp., and Oligonychus peruvianus McGreg...

The cassava mealybug has a defense mechanism against its natural enemy Epidinocarsis lopezi. When the female wasp lays its eggs inside the mealybug, the mealybug`s blood cells surround or encapsulate the parasitoid`s egg or larvae. This is followed by a hardening or blackening of the capsule, cal...

Damage caused by the fruit fly Bactrocera dorsalis (Hendel) (syn. B. invadens Drew, Tsuruta & White) (Diptera: Tephritidae) on mangoes in Senegal leads to production losses. A potential biological control agent against this pest is the weaver ant Oecophylla longinoda Latreille (Hymenoptera: Formi...

A total of 72 fungal endophytes were isolated from surface-sterilized roots of healthy 'Gros Michel' (AAA genome, Gros Michel subgroup) banana plants in Turrialba, Costa Rica. In vitro and in vivo tests were carried out in order to identify microorganisms with potential activity against Fusarium ...

Endophytic colonization by the fungus Fusarium oxysporum can result in increased host resistance topests and diseases, and greater biomass production. However, few studies have assessed the field performanceof this fungus for biological control of pests and diseases in banana. Further to greenhou...

On-farm augmentative releases of the parasitoid Habrobracon hebetor (Say) for controlling the millet head miner (MHM) Heliocheilus albipunctella (de Joannis) were tested in Burkina Faso, Mali and Niger from 2007 to 2009. In addition, a survey of farmers’ perceptions of insect pests, with particul...

In many African countries, the misuse of chemical insecticides is questioned with the awareness of their negative effects on ecosystems and human health. There is, therefore, constant request from consumers for alternatives to chemical insecticide in plant protection. In the present study, the ef...
