Incidence, abundance and damage by the sweet potato butterfly (Acraea acerata Hew. and the African sweet potato weevils (Cylas spp.) across an altitude gradient in Kabale district, Uganda

Insights on the effects of temperature variation on insect pest damage characteristics gained in the present study suggest a possible geographical shift by the pests to higher altitudes due to global warming.

Guilty by association: an evaluation of millipedes as pests of carrot and sweet potato

This study is the first North American survey of millipedes on arable soils and the first evaluation of North American millipede damage to sweet potatoes and carrots and concluded that the majority of field‐observed damage was caused by wireworms.

Effectiveness of cultural practices and sweet potato varieties (Ipomoea batatas Lam) in managing sweet potato weevil (Cylas spp) in Zanzibar

The results show that varieties, vine portion and cultural practices have significant effect on sweet potato weevil incidence and severity, and Mayai was significantly (p<0.05) higher than Mbirimbi and Shangazi in variety.

Reaction of sweet potato genotypes to sweet potato weevils (Cylas puncticollis (boheman) and Alcidodes dentipes (olivier), coleoptera: curculionidae) and viruses in Eastern Hararge, Oromiya, Ethiopia

It is concluded that the resistant sweet potato genotypes identified for SPW and SPVD could be utilized in integrated sweet potato production for the locations where the pests are major production bottleneck, like in Eastern Hararge.

Development of efficient integrated management package against sweet potato weevil (Cylas formicarius [Fabricius, 1798])

The sweet potato weevil (Cylas formicarius, 1798) is one of the most damaging sweet potato pests. To prevent an economic crop loss, it is very important to develop a suitable and efficient integrated

Pest Status of Acraea acerata Hew. and Cylas spp. in Sweetpotato (Ipomoea batatas (L.) Lam.) and Incidence of Natural Enemies in the Lake Albert Crescent Agro-ecological Zone of Uganda

The present study presents the results of farmers’ field surveys of the sweetpotato butterfly, Acraea acerata Hew., and the two African sweetpotato weevils, Cylas puncticollis Boheman and C. brunneus

The Major Sweet Potato Weevils; Management and Control: A Review

Sweet potato is an important food crop, grown commonly in tropical and subtropical regions, but production has been subjected to less research worldwide, compared to the major staple crops. Sweet



Soil Pests of Groundnut in West Africa—Species Diversity, Damage and Estimation of Yield Losses

Among the major arthropods in soil and plant samples taken from groundnut farms during the 1996 cropping season in Mali, Burkina-Faso, Niger, and Nigeria, termites in the genus Microtermes (Isoptera:

Termite Damage and Crop Loss Studies in Nigeria—a Survey of Damage to Groundnuts

The chemical control of termites is economically viable on mechanised farms in the Sudan savanna, but cannot be justified on peasant farms, where yields are too low.

Termite Damage and Crop Loss Studies in Nigeria—the Incidence of Termite-Scarified Groundnut Pods and Resulting Kernel Contamination in Field and Market Samples

The incidence of termite-scarified groundnut pods and resulting kernel contamination in field and market samples were studied in northern Nigeria and found that scarification was more common in the Sudan Savanna vegetation zone.

Pests and diseases of groundnuts in Malawi. II. Disorders of pods, kernels and seedlings.

Diseases of pods, kernels and seeds and their prevention and control are described. Fungi isolated from pod rots and surface-sterilized kernels are listed. Fusarium oxysporum and F. solani f.sp.

The influence of the testa, damage and seed dressing on the emergence of groundnut (Arachis hypogea)

There was a high correlation between the number of seedlings which emerged in these trials and the resistance or susceptibility of the seed to invasion by the fungus Aspergillus flavus, as assessed by laboratory tests.

Water Relations and Desiccation Tolerance of Migrating Garden Millipedes (Diplopoda: Paradoxosomatidae)

The water relations and desiccation tolerance of migrating adult garden millipedes, Oxidus gracilis Koch, were examined and a biologically based cultural control strategy is presented.
