“…Red Palm Weevil (RPW), Rhynchophorus ferrugineus (Coleoptera: Curculionidae), is obnoxious to stem tissues of oil palm trees in West Africa. In Nigeria, Ottun et al (2021) inoculated larvae of R. ferrugineus with native Heterorhabitis sp. and observed that 84% of the pest died after 9 days post-inoculation.…”

Entomopathogenic nematodes (EPNs) are a type of soil-dwelling nematodes with a remarkable ability to infect insect pests. Their employment for control of pests is a means to foster sustainable agricultural practices. These environmentally safe alternatives to pesticides are being researched in Sub-Saharan Africa (SSA), but there are many gaps to be filled, which this review exposes. The systematic analysis of peer-reviewed articles from 2003 to 2022 shows that about 56% of published articles on EPNs in Sub-Saharan Africa (SSA) come from studies in South Africa. In SSA, applied pest management studies of these nematodes have focused on Lepidopteran (41.7%), Coleopteran (22.2%), and Hemipteran (18.1%) pests, withCydiasp.,Planococcussp., andThaumatotibiasp. being the most targeted genera. Many areas in SSA remain unexplored for EPNs and knowledge of their use is still experimental. There is a paucity of knowledge regarding the bacteria symbionts of indigenous EPNs in SSA, with the possibility of variations in bacterial symbionts being associated with specific ecological populations. However, promising strides have been made, and further surveys are needed to explore untapped geographies. Utilizing native EPN species holds promise in curbing the reliance on hazardous pesticides and promoting integrated pest management approaches in SSA, representing a sustainable method for pest control.

“…Elsewhere, in the complex of biological control agents, entomopathogenic fungi appear to be more effective and most successfully utilized insect pathogen, especially in the genera Aspergillus , Beauvaria , Metarhizium and Lecanicillium [ 83 ]. Preliminary work by Ottun et al, [ 84 ] revealed that there is great potentialfor the possibility of using entomopathogenic nematodes in the management of insect pests in Nigeria.…”

Insect pest infestations and damage can limit the production of vegetables in the farming systems in Nigeria. This review looks at integrated insect pest management as a possible panacea for resolving insect pest issues in vegetable crops. The main vegetable crops which include okra, tomatoes, chilli peppers, cucumbers, green amaranth, carrots and onions are highlighted. The major insect pests of the various vegetables which include foliage beetles, caterpillars, aphids, fruit flies, stink bugs, and grasshoppers are also mentioned. The various control measures that have been empirically verified for the mitigation of the impact of these insect pests, including the application of synthetic insecticides, modification of agronomic practices, use of resistant varieties, application of botanicals, biological and mechanical controls, are discussed. Studies which have been carried out attempting to integrate two or more of the control strategies for better insect pest control are also reviewed. Strategies that can be put in place for the integrated pest management of vegetable insect pests in Nigeria are considered. Among the IPM (Integrated Pest Management) practices instituted for the mitigation of pest infestations on vegetable crops in Nigeria, intercropping of suitable vegetables in combination with the application of aqueous extracts of Azadirachta indica and Piper guineense seeds under good farm hygiene and sanitation proved to be most successful.
