Infestation of crop fields by Striga species in the savanna zones of northeast Nigeria

Autor: Dugje, I.Y. Kamara, A. Omoigui, L.O.

Parasitism of crop plants by Striga species is a major constraint in the savanna zones of West Africa. Farmers ranked Striga as a leading constraint during a livelihood analysis of 30 communities in northeast Nigeria. A field survey was conducted to ascertain the extent of infestation by Striga s...

Effect of planting date on incidence and damage by Sesamia calamistis (Lepidoptera: Noctuidae) in maize in southern Benin

Autor: Adda, C. Atachi, P. Hell, K. Korie, S. Tamo, M.

Stem and cob borers cause substantial damage to maize and affect the quality and economic value of maize in West Africa. Manipulation of planting dates is considered a possible mechanism for averting the overall impact of borers and their damage to the crop. Experiments were carried out in southe...

Nitrogen effects on Striga hermonthica infestation, grain yield and agronomic traits of tolerant and susceptible maize hybrids

Autor: Kim, S.K. Adetimirin, V.O. Akintunde, A.Y.

phytoparasite, Striga hermonthica (Del.) Benth., infests millions of hectares of cultivated fields of cereal crops in sub-Saharan Africa. Yield losses are often 70 but can be as high as 100% and farmers often abandon infested fields and move to new areas. The objectives of this study were to inve...

Genetic loci controlling carotenoid biosynthesis in diverse tropical maize lines

Autor: Azmach, G. Menkir, A. Spilane, C. Gedil, M.

The discovery and use of genetic markers associated with carotenoid levels can help to exploit the genetic potential of maize for provitamin A accumulation more effectively. Provitamin A carotenoids are classes of carotenoids that are precursors of vitamin A, an essential micronutrient in humans....

Autor: Asanzi, C.M. Bosque Pérez, N.A. Nault, L.R.

The movement of Cicadulina storeyi China (Homoptera: Cicadellidae), vector of maize streak geminivirus, within maize (Zea mays L.) fields was studied using mark, release and recapture experiments. Cicadulina storeyi, marked with fluorescent dye, were released at dusk and monitored for 14 days usi...

Autor: Ndemah, R. Schulthess, F. Korie, S. Borgemeister, C. Cardwell, K.F.

Geographic distribution, relative importance, and effect of lepidopterous stem and ear borers on maize, Zea mays L., were studied in the humid forest and the mid-altitude zones of Cameroon from 1994 to 1997. Six villages were chosen in the forest zone and grouped into three blocks representing gr...
