Download or read book Weather and the Epidemiology of the African Armyworm Spodoptera Exempta written by M. R. Tucker and published by Hyperion Books. This book was released on 1993 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summarizes work carried out in the African armyworm seasons during 1972-88 in relation to frequency of outbreaks and weather conditions. The use of trajectory analysis in estimating the migration paths of windborne moths during the season is discussed together with the importance of rainstorms in concentrating the moths to cause an outbreak. Of interest to those working in the field of predictive techniques in migration research, and those planning control operations against this serious pest.

Book excerpt: The African armyworm, Spodoptera exempta (Walker) (Lepidoptera: Noctuidae is a serious migratory pest of cereal crops and grasslands. It can impact upon the livelihoods of farmers in many countries of sub-Saharan Africa, Yemen, some Pacific islands and parts of Australia. Containing as much up-to-date information as possible on the biology, ecology, epidemiology and management of this pest as well as containing an extensive list of useful references, this handbook will be of interest to those working in the agricultural sector, particularly those reponsible for the control of migrant pests.

Available in PDF, EPUB and Kindle. Book excerpt: Knowledge of the flight behaviour of migrant insect pests is essential for an understanding of their population dynamics, which in turn determine the design of efficient management strategies. This bulletin provides a detailed review of the development of radar entomology, spanning the last 30 years, and its contribution to the study of major insect pests of agriculture and human health in the developing world. Pests include grasshoppers and locusts, the African armyworm, rice brown planthopper and other rice pests, the old world bollworm and some mosquito vectors of human diseases.

Download or read book Agroclimatology written by Jerry L. Hatfield and published by John Wiley & Sons. This book was released on 2020-01-22 with total page 656 pages. Available in PDF, EPUB and Kindle. Book excerpt: Can we unlock resilience to climate stress by better understanding linkages between the environment and biological systems? Agroclimatology allows us to explore how different processes determine plant response to climate and how climate drives the distribution of crops and their productivity. Editors Jerry L. Hatfield, Mannava V.K. Sivakumar, and John H. Prueger have taken a comprehensive view of agroclimatology to assist and challenge researchers in this important area of study. Major themes include: principles of energy exchange and climatology, understanding climate change and agriculture, linkages of specific biological systems to climatology, the context of pests and diseases, methods of agroclimatology, and the application of agroclimatic principles to problem-solving in agriculture.
