The experiment was conducted to find out the efficacy of dodder vine extract as seed protectant against pulse beetle, Callosobruchus chinensis on gram seed in the laboratory of the Department of Entomology, Bangladesh Agricultural University, Mymensingh during the period of February to May, 2009. The concentrations of dodder vine extract were 5, 2 and 1% respectively. Efficacies of these treatm...

Cowpea (Vigna unguiculata [L.] Walp.) yields are considerably low in Namibia due to lack of improved varieties and biotic and abiotic stresses, notably, recurrent drought. Thus, genetic improvement in cowpea aims to develop cultivars with improved grain yield and tolerance to abiotic and biotic stress factors. The objective of this study was to identify agronomically desirable cowpea genotypes ...

the objective of the study was to evaluate chemical composition, in vitro dry matter digestibility (ivdmd), and growth performance of weanling boer-goats supplemented with cowpea seed hulls (csh) and commercial concentrate / feed (cf) with natural pasture as basal diet. weanling boer-goats (n=36) were assigned to 3 treatments comprising of 4 animals each (2 bucklings and 2 females) replicated t...

After decades of research on cowpea, significant amount of omics datasets are available and useful in understanding the genetic relationship between Vigna unguiculata ssp. unguiculata and other species belonging to the same genus as well as its genetic variation. Besides, the development of genetic map allowed the chromosome localization of molecular markers associated with disease resistance, ...

A field inoculation method was developed to produce Meloidogyne spp. infestation sites with minimal quantities of nematode inoculum and with a reduced labor requirement compared to previous techniques. In a preseason-methyl bromidefumigated site, nematode egg suspensions were delivered at concentrations of 0 or 10(x) eggs/m of row where x = 2.12, 2.82, 3.52, or 4.22 through a drip line attached...

Seed size distinguishes most crops from their wild relatives and is an important quality trait for the grain legume cowpea. In order to breed cowpea varieties with larger seeds we introgressed a rare haplotype associated with large seeds at the Css-1 locus from an African buff seed type cultivar, IT82E-18 (18.5 g/100 seeds), into a blackeye seed type cultivar, CB27 (22 g/100 seed). Four recombi...

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...

the seed beetle, stafor limbatus (horn) (col.: bruchidae), collected from bushehr and yazd provinces, iran, on acasia sp. and prosopis farcta, is newly recorded from iran. it is native to southwestern united states but distributed in various parts of the world. the beetle was identified by delobel from france.

Tree-killing bark beetles are major disturbance agents affecting coniferous forest ecosystems. The role of environmental conditions on driving beetle outbreaks is becoming increasingly important as global climatic change alters environmental factors, such as drought stress, that, in turn, govern tree resistance. Furthermore, dynamics between beetles and trees are highly nonlinear, due to comple...
