Plant volatile signatures are often used as cues by herbivores to locate their preferred hosts. Here, we report on the volatile organic compounds used by the subterranean root-knot nematode (RKN) Meloidogyne incognita for host location. We compared responses of infective second stage juveniles (J...

An expt. to study the background soil effects associated with var. resistance in bean pest populations, virus incidence and yield was carried out at the Centro Internacional de Agricultura Tropical (CIAT), Palmira, Colombia from Jan.-March, 1978. The effect of the treatments and of the var. on Em...

The development and release of Negro Huasteco 81, a black- seeded bush bean var., are described. This line was consistently the most tolerant from a total of 25 BGMV-tolerant lines and var. introduced from a collaborative project between CIAT and the Instituto de Ciencia y Tecnologia Agricolas, G...

The effect of maize/bean intercropping on Empoasca kraemeri population and damage, populations of other phytophagous insects, the parasitic action of Anagrus sp. on E. kraemeri, ambient temp. and RH, light intensity, and bean leaf temp. was observed. Two planting dates and 3 maize densities in 2 ...

Cowpea [Vigna unguiculata (L.) Walp] is an important grain legume crop grown for its protein rich grains. It is an inexpensive source of protein in the diets of people in sub-Saharan Africa. The International Institute of Tropical Agriculture (IITA) has been working on the improvement of cowpea f...

Host location, acceptance and larval success were studied in a mixed cultivar trial consisting of three East African cooking bananas, two East African beer banana and Kayinja (an exotic cultivar used for beer making). Weevil damage to the endemic cultivars was 5 to 25 times higher than that of Ka...

A field study was conducted to determine the rate of genetic improvement in grain and fodder yields and associated agronomic and physiological changes of determinate and semideterminate cowpea [Vigna unguiculata (L.) Walp.] genotypes developed in the Nigerian Sudan savannas in 1974 to 2004. Resul...

Bean diseases such as rust (Uromyces phaseoli var. typica), web blinght (Thanatephorus cucumeris) and angular leaf spot (Isariopsis griseola), not only destroy plant foliage but also cuase physiological damage. To determine yield losses, the cv. ICA-Gualì and porrillo sintetico were artificially ...

Data obtained from the international Bean Rust Nursery (IBRN) in 1975-76 showed that none of the 132 cv. and breeding lines tested was resistant to bean rust; however, some were susceptible only in specific geographical regions. CIATs bean program has concentrated its efforts on selecting rust-re...
