Fatty acid composition of extracted oils from 58 lines of cowpea (Vigna unguicuiata (L) Walp) was investigated by gas‐liquid chromatography (GLC). Considerable variability was observed in the fatty acid profile, though palmitic (16:0), linoleic (18:2) and linolenic (18:3) acids were the dominant ...

Aphid (Aphis craccivora Koch) is a major pest of cowpea [Vigna unguiculata (L.) Walp.] particularly in the drier regions of the tropics. It causes direct damage by feeding on the plants and also transmits viruses. Several sources of resistance to cowpea aphid have been identified and efforts are ...

Journal Article 1992

Autor: Mesfin, T. Thottappilly, G. Singh, S.R.

The feeding activity of Aphis craccivora (Koch) was monitored on cowpea plants of aphid‐susceptible (Vita 7) and aphid‐resistant (TVu 801) cultivars, using an AC electronic feeding monitoring system. Waveforms corresponding to salivation, phloem ingestion and non‐phloem ingestion were observed. A...

Twelve cowpea cultivars were screened for reactions to infection by Colletotrichum lindemuthianum and C. truncatum, causal agents of anthracnose and brown blotch diseases, respectively. Three different inoculation techniques were used: spraying a spore suspension on leaves of seedlings, injecting...

The most damaging storage pest in cowpea [Vigna unguiculata (L.) Walp] is Callosobruchus maculatus (F.), commonly known bruchid. Therefore, concerted efforts are being made at the International Institute of Tropical Agriculture (IITA) to develop bruchid-resistant cowpea varieties. By systematic s...

This study was undertaken to elucidate the nature of inheritance of resistance to bruchids [Callosobruchus maculatus. (F.)] in cowpea [Vigna unguiculata (L.) Walp.]. The parental F1, F2, and backcross populations involving three resistant and two susceptible parents were bioassayed in the laborat...
