Eight insecticidal crystal proteins of Bacillus thuringiensis, CrylAa, CrylAb, CrylAc, CrylB, Cry2Aa, CrylC, CrylDa and Cry 1Ea were assessed for toxicity against 1 st instar larvae of rice leaf folder, Cnaphalocrocis...Eight insecticidal crystal proteins of Bacillus thuringiensis, CrylAa, CrylAb, CrylAc, CrylB, Cry2Aa, CrylC, CrylDa and Cry 1Ea were assessed for toxicity against 1 st instar larvae of rice leaf folder, Cnaphalocrocis medinalis （Guenee） at 48 HAT and 72 HAT. Bioassay results depicted CrylAa was the most toxic （LCso 2.35 ppm） followed by CrylBa （LCso 8,50 ppm） and CrylAb （LCso 8.73 ppm） at 48 HAT, whereas, at 72 HAT CrylAb proved to be highly toxic （LC50 0.50 ppm） followed by CrylAa （LCso 4.07 ppm）, CrylAc （LCso 4,84 ppm） and CrylBa （LCso 6.42 ppm）. Toxins Cry2Aa, CrylCa, CrylDa and CrylEa did not resulted in any mortality at 48 HAT and 72 HAT, respectively. Baseline estimates for CrylAb against 1st instar larvae of C. medinalis sampled from seven geographical locations revealed variation in LC50＇s from 0.37 ppm to LC50 16.25 ppm at 48 HAT and LC50 0.50 ppm to LC50 6.49 ppm 72 HAT, respectively with relative resistance ratios of 44-fold and 13-fold at 48 HAT and 72 HAT over the susceptible population.展开更多

This part of Namibia has both arid and semi-arid climates. These climates require the growing of drought-resistant fodder trees to aid in the provision of animal feed or supplement. This is paramount to livestock farmers who are striving to meet the feed demand of their animals especially during winter and drought periods. It is upon this background that both Moringa species were grown to evaluate their field growth performances. Moringa oleifera grew faster with 224.9 cm and 281.45 cm heights than Moringa ovalifolia that had 77.025 cm and 113.2 cm heights in 2014/2015 summer season (October 2014 to April 2015) and 2015/2016 summer season (October 2015 to April 2016), respectively, although Moringa ovalifolia is native to Namibia. In Namibia, summer usually starts October and ends April the follow year after which winter follows. Moringa oleifera grew significantly higher (P Moringa ovalifolia, though they belong to the Moringaceae family and were grown under the parallel conditions. Therefore, Moringa oleifera would serve as a better alternative for improving rangelands’ productivity under these adverse climatic and environmental conditions since it can grow faster than Moringa ovalifolia, whose characteristic leads to the rapid establishment of trees and large quantity of leaf-biomass production.展开更多
