The bean pod borer, Maruca vitrata Fabricius (Lepidoptera: Crambidae), is a serious pantropical pest of grain legumes. A suitable artificial diet is desirable for producing uniform insects for commercial purposes or research. Three previously described artificial diets, 1 newly-developed artificial diet, and cowpea (Vigna unguiculata (L.) Walp. (Fabales: Fabaceae)), the natural hostplant of M. ...

This study was conducted at the Department of Crop Science and Technology Research farm, Federal University of Technology, Owerri, during 2010 cropping season. The experiment was laid out in Randomized Complete Block Design. The plant extracts were tested at four rates (0.00, 1.00, 2.00 and 3.00 ml/ plot), and Pirimiphos-methyl (Actellic 25 E. C) at the rates of 1.25, 2.50 and 3.75 ml/ plot. Th...

use of the growth indices is a method to assessment of intercropping efficiency. in order to evaluation growth indices of soybean, sweet basil and borage in intercropping with different ratios, an experiment base on randomized complete block design was conducted with 9 treatments and 3 replications at north khorasan in 2011. treatments were consisted of the plants pure culture, replacement seri...

A study to evaluate the fungitoxic and phytotoxic effects of extracts of V. amaygdalina, B. pinnatus, O. gratissimum and E. globules on the fungal pathogens inducing wilting on cowpea grown in Ago-Iwoye, South Western Nigeria. The extracts of all the botanicals used reduced Disease Infection Rate (DIR) in treated plants. Sclerotium rolfsii sacc induced wilting of between 4 and 12% on cowpea see...

The objective of this study was to identify the effect of different drying methods on vitamin A activity of formulated weaning food. Weaned foods on vitamin A activity of formulated using treated cowpea flour, locally available rice flour, banana-pumpkin, skim milk powder and sugar in the ratio 35:35:15:15:5. Treated cowpea flour consisted of original cowpea flour, 24 h germinated cowpea flour....

Development of more effective and less toxic antifungal agents is required for the treatment of dermatophytosis. Plants and their extraction preparations have been used as medicines against infectious diseases. In this research, the lemon grass [Cymbopogon citrates DC.) Stapf.], lantana (Lantana camara L.), nerium (Nerium oleander L.), basil (Ocimum basilicum L.) and olive leaves (Olea europaea...

Vigna unguiculata (L.) Walp (cowpea) is a food crop with high nutritional value that is cultivated throughout tropical and subtropical regions of the world. The main constraint on high productivity of cowpea is water deficit, caused by the long periods of drought that occur in these regions. The aim of the present study was to select elite cowpea genotypes with enhanced drought tolerance, by ap...

Quality Protein Maize is an improved variety of maize which contains higher amount of lysine and tryptophan. Cowpea is an indigenous legume widely consumed in Nigeria. Quality Protein Maize was malted by steeping, germinating, drying and milling while cowpea was dehulled, steamed, dried and milled. The resulting flours were blended to produce complementary food at ratios of 100:0; 70:30 (Qualit...

The effect of 2-tridecanone vapor on the cowpea weevil (Callosobruchus maculatus) development was determined. Seeds of cowpea were infested with adults and exposed to different doses of 2-tridecanone isolated from Pilocarpus microphyllus Stapf ex Holm, a plant species native from northeastern Brazil. The pure monoterpene was evaluated both undiluted as well as in the dilutions 1:10, 1:100 and 1...

the study investigates consumers’ preference for cowpea reflected in the nigerian markets through price discounts and premiums that consumers pay for different cowpea characteristics. the price data used for this study were obtained through a market survey. a common data collection protocol was employed. every month, between october 2009 to december 2010, five cowpea samples per seller were bou...
