Journal Article 1992

Autor: Bottenberg, H. Irwin, M.E.

Aphid landing rates were monitored with horizontal mosaic green pan traps in monocultures of soybean, Glycine max (L.) Merrill, and in additive mixtures of soybean with dwarf or tall isolines of sorghum, Sorghum bicolor (L.) Moench. Rhopalosiphum maidis (Fitch) colonized sorghum whorls and was th...

Rhopalosiphum maidis (Fitch) dominated the aerial aphid plankton in bean (Phaseolus vulgaris L.) monocultures and mixed cultures of bean with corn (Zea mays L.) in Illinois. It was also the most common species landing on bean plants in this study during the summer of 1987. More flight activity wa...

The population dynamics of major cowpea pests was studied in northern Nigeria during 1992-95 in both the wet and dry seasons. Rainfall cowpea is grown as a subsistence crop, mixed at low densities with cereals. Dry-season cowpea is irrigated or grown on residual moisture in monocultures as a cash...

Biological control, as a key component of biointensive IPM in cowpea, is evaluated for its practical feasibility. The case study of one of the major insect pests, the bean flower thrips Megalumthrips sjosredti (Trybom) (Thysanoptera, Thripidae), is used to indicate the most important criteria for...

Autor: Bottenberg, H.

Farmers of rainfed cowpea/groundnut/millet/sorghum cropping systems in Kano, Nigeria, ranked arthropods as the major production constraint in cowpea and groundnut in 1991 and 1992. At least 25% of the farmers also reported severe infestations by Striga gesneroides a parasitic weed of cowpea. Drou...
