Effect of different crops on the cuticle length, weight and total body weight of Kraussaria angulifera (krauss) in Sahel and Sudan Savanna Zones of Borno State, Nigeria
Abstract
The experiment was conducted in a screen house in Jere (130 9N, 110 4E) and Maiduguri (120 8N, 120 5E) of Borno State in 2015 to evaluate the effects of different crops on the cuticle and body weight of Kraussaria angulifera (Krauss) in the Sahel and Sudan Savanna zones. The experiment was laid in a completely randomized block design. Experimental cage of 6˟4.5˟1m, was divided into 6 compartments of 1x1.5x1m planted to 6 crop treatments of maize, sorghum, millet, maize and sorghum, sorghum and millet, millet and maize and replicated 3 times. Seven day old F1 nymphs were introduced into each compartment. Data collection was done every week for the above variables. The results obtained in the two zones revealed that nymphs fed on millet had the longest (36.17) mean length of cuticle at instar five when compared to the other treatments. Nymphs fed on maize had the least (33.17) mean length of cuticle. The weight of cuticle also showed that nymphs fed on millet had the highest (0.065g) weight of cuticle while nymphs fed on maize had the least (0.063g). Data on total body weight showed that nymphs fed on crop mixture from nymph IV to adult recorded the highest total weight than those fed on sole crop.
