Anopheles arabiensis breeding was studied during March 1999-June 2000 in New Halfa town. Of 3642 anopheline larvae collected, 3633 (99.75%) were A. arabiensis: 82.49%, 11.56%, 3.08% and 2.88% of the larvae were collected from shallow sunlit pools resulting from pipes leakages, rain pools, irrigation canals and man-made pools respectively. The overall mean density was 24.34 larvae/10 dips: 40.73...

Cross-sectional entomological surveys were carried out during the 2006 dry and rainy seasons in Lagdo, Cameroon to measure the impact of rice cultivation on malaria transmission and to monitor vector susceptibility to insecticides. Adult anopheline mosquitoes were captured on human volunteers and by pyrethrum spray collections. A total of 4740 mosquitoes was collected during the study. Anophele...

Tomato is sensitive to a number of environmental stresses, especially extreme temperature, drought, salinity and inadequate moisture stresses (Kalloo, 1993). In Bangladesh, lack of irrigation and drought resistant cultivars are the central problems for tomato cultivation. In the dry season with high temperature, flower abortion occurs and fruits drop frequently, which causes very poor yield of ...

Proso millet (Panicum miliaceum L.) is a warm season grass with a growing season of 60-100 days. It is a highly nutritious cereal grain used for human consumption, bird seed, and/or ethanol production. Unique characteristics, such as drought and heat tolerance, make proso millet a promising alternative cash crop for the Pacific Northwest (PNW) region of the United States. Development of proso m...

Commercial floriculture is an emerging profitable agro industry in the world with great demand of cut flowers but a constraint to regulate supply for longer duration markets. The off-season plucked get better price, as glut during peak season affects profits. This could be achieved by cultivating varieties over wide range planting times which demands evaluation varietal performance under differ...

Abstract The objective of this work was to simultaneously select pre-commercial grain sorghum hybrids with high adaptability and yield stability, through mixed modeling, in 20 environments, during six years. evaluated plant material consisted 57 commercial hybrids. In all experiments, were arranged a triple lattice design; some experiments used 6x6 lattice, others, 5x5 lattice. Adaptability sta...
