(Chilli) as protectants of cowpea (Vignaunguiculata) against Callosobruchusmaculatus during storage. The powders were obtained as described by Asawalan and Arukwe (2004). Uninfested cowpea seeds were sterilized for two (2) weeks to kill prior infestation. 50g of sterilized cowpea in plastic containers were treated with 1g, 2g and 3g of chilli and orange powders respectively. These were then infested with five (5) adult weevils comprising three (3) females and two (2) males obtained from the insect culture. Highest mortality was recorded on cowpea treated with 3g chilli powder with a mean of 5.00 (33.33%) and cowpea treated with 2g and 3g orange peel powder respectively. Few eggs were laid on cowpea treated with chilli powder and orange peel powder with mean of 18.00 and 7.33 respectively compared to the control 11.33- 20.67. Highest percentage emergence was recorded on cowpea treated with 3g chili powder (72.57%) and the lowest percentage emergence was recorded on cowpea treated with 1g orange peel powder (22.78%) ...Preview Download Preview +Other Science Technology project topics and materials you might be interested in»Design and construction of cell phone charger»Bacteriological qualities of food thickener deuterium microcarpum (ofor) and brachystegia eurcycoma (achi) sold in Owerri main market»Physiochemical assessment of soil samples from Nwambe Reserve Forest, Ndubia Igagu Izzi L.G.A, Ebonyi State.»Obstacle detection robot with ultrasonic sensor»Antitrypanosomal activity of ethanol extract of Tridax Procumbent leaf and whole flower on T.
