Evaluation of resistance in selected cocoa genotypes to the brown cocoa mirid, Sahlbergella singularis Haglund in Nigeria
The use of host-plant resistance is the most economic and ecologically sound option for the control of the most important insect pest of cocoa, Sahlbergella singularis leaving no deleterious sideExpand
Effects of cocoa tree phenology and canopy microclimate on the performance of the mirid bug Sahlbergella singularis
Fecundity as well as life table parameters varied in accordance with natural population fluctuations, suggesting that S. singularis seasonal variation might be mainly linked to variation in female fecundity. Expand
Field Evaluation of Predacious Mites (Acari: Phytoseiidae) for Biological Control of Citrus Red Mite, Panonychus citri (Trombidiformes: Tetranychidae)
All 3 phytoseiid species were effective in reducing P. citri densities on citrus, however, initial prey density may be an important factor influencing their performance. Expand
Dieback of cocoa (Theobroma cacao L.) plant tissues caused by the brown cocoa mirid Sahlbergella singularis Haglund (Hemiptera: Miridae) and associated pathogenic fungi
The effect of mirid — pathogenic fungi-associated damage could be ameliorated through effective crop husbandry practices to ensure that cocoa plant tissues are not unduly exposed to biological and mechanical injuries. Expand
Laboratory and Field Evaluation of an Indoxacarb Gel Bait Against Two Cockroach Species (Dictyoptera: Blattellidae, Blattidae) in Lagos, Nigeria
Indoxacarb gel bait was highly effective in the control of cockroaches and was toxic to both P. americana and B. germanica. Expand
Pesticidal efficacy of three tropical herbal plants' leaf extracts against Macrotermes bellicosus, an emerging pest of cocoa, Theobroma cacao L.
Ethanol enhanced/potentiated the bio-insecticidal activities of some of the plant extracts used in this study and further studies are needed to know the fractional constituents of each plant species that is insecticidal in all the plants used inThis study. Expand
Heavy Metal Accumulation and Arthropod Abundance in Leafy Vegetable Cultivation
The concentration of heavy metals from this study did not exceed safe limits, hence there was a fair abundance and diversity of insects found on the leafy vegetables. Expand
Distribution and damage characteristics of an emerging insect pest of cashew, Plocaederus ferrugineus L. (Coleoptera: Cerambycidae) In Nigeria: A preliminary report
Observations at Ochaja in 1999/2000 and at Ibadan in 2005 of “sudden death” of mature cashew trees within few weeks of infestation were indications of emergence of new pest of cashew in Nigeria, which needs urgent investigation. Expand
Bioefficacy of Skeeter Abate and Spintor on Aanopheles gambiae and Aedes aegypti Mosquitoes from insecticide resistance areas in Lagos and Oyo States, Nigeria
There is a positive correlation between resistance to permethrin in adult mosquitoes and the concentration of Spintor and Skeeter Abate required to effect 99% mortality in the larval samples, which should be conducted before embarking on mosquito control programmes. Expand
The population dynamics of the brown cocoa mirid, Sahlbergella singularis haglund in Ibadan, Nigeria
The brown cocoa mirid, Sahlbergella singularis Haglund, has been adjudged the most economically important insect pest of cocoa across West African the sub-region and the interactions between field populations of mirids and density dependent and density independent factors are presented. Expand
