Modeling evolution of resistance by Maruca vitrata (Lepidoptera: Crambidae) to transgenic insecticidal cowpea in Africa.
We created a detailed model of the Maruca vitrata (F.) and cowpea [Vigna unguiculata (L.) Walp] system to study the possible evolution of resistance by the insect to transgenic insecticidal cowpea, which is under development. We focused on population dynamics and genetics in a region of west Africa. We simulated single-toxin and pyramided (two-toxin) cowpea and emphasized conservative, worst-c...
متن کاملSex pheromone recognition and characterization of three pheromone-binding proteins in the legume pod borer, Maruca vitrata Fabricius (Lepidoptera: Crambidae)
Pheromone-binding proteins (PBPs) are essential for the filtering, binding and transporting of sex pheromones across sensillum lymph to membrane-associated pheromone receptors of moths. In this study, three novel PBP genes were expressed in Escherichia coli to examine their involvement in the sex pheromone perception of Maruca vitrata. Fluorescence binding experiments indicated that MvitPBP1-3 ...
متن کاملNew Artificial Diet for Continuous Rearing of the Bean Pod Borer, Maruca vitrata
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. ...
متن کاملProductivity of Millet / Cowpea Intercrop as Affected by Cowpea Genotype and Row Arrangement
Six cowpea genotypes (Danila, IT96D-772, IT90K-277-2, IT95K-1091-3, IT96D-740, IT96D-757) were intercropped with a local millet cultivar using four row arrangements (1:1, 1:2, 2:2 and 2:4 millet to cowpea rows) in a field experiment conducted at Minjibir near Kano in the Sudan savanna ecological zone of Nigeria during the 1999 and 2000 wet seasons. Cowpea genotypes and row arrangement had no ef...
متن کاملDifferent sowing dates affected cotton yield and yield components
This study was conducted to determine whether selecting an optimum sowing date couldimprove yield. The experiment consisted of sowing a film-covered, drip-irrigated cotton field onfour sowing dates from April to May in 2011-2012 at the Agrometeorological ExperimentalStation of Wulanwusu, which was in an arid region of north-western China. Late sowing datesproduced less yield and water-use effic...
