African Cereal Stem Borers
An assemblage of approximately twenty moth species belonging to the families Crambidae, Pyralidae and Noctuidae constitute the most important cereal pests in many parts of Africa. The caterpillars of these moths bore into the stems of maize, sorghum, millet and rice, often killing the plant, and are commonly known as stem or stalk borers. The cereals attacked are grown on small farms to feed the farmers and their families and are of great importance as the staple food for the population in most parts of Africa. Complex control measures, including the use of chemicals, are often inappropriate. This book provides the information necessary for pursuing integrated pest management of African cereal stem borers, in particular strategies using natural enemy components. The book begins by characterizing the economically important species by region and by their biology and host plants. The book then describes in detail the taxonomy and rearing techniques for the moths, their larvae and their natural enemies. It includes illustrated keys of species and lists of distributions and hosts, and it concludes with a summary of current control measures and those being investigated.
Biological Control of Rice Stem Borers
Biological control - general discussion; Feasibility of successful biological control of rice stem borers; Procedural considerations.
A Handbook of Field Methods for Research on Rice Stem-borers and Their Natural Enemies
The population of many Asian countries are dependent on rice for their staple diet and therefore any insight into the ecology of rice stem-borers and their natural enemies would not only be of scientific interest, but also of considerable economic value. This handbook presents some of the methods that might prove useful in carrying out such research, and thus makes it possible to speed up the progress of research on the insects in question in sub-tropical and tropical rice-growing areas.
Insect-resistant Maize
Many farmers in sub-Saharan Africa suffer heavily from crop losses due to stem borer pests. Insecticides are often unaffordable; therefore, maize plants must be made resistant to pests. The 'Insect Resistant Maize for Africa' (IRMA) project in Kenya was aimed at developing new maize varieties both by conventional methods and by biotechnologically incorporating the endotoxin produced by the soil bacteriumBacillus thuringiensis. The author gives an impartial and chronological account of this exemplary project between 1999 and 2008, supplemented by discussions of agricultural development policy and descriptions of Kenyan smallholders and the project team. He also takes critical and rational positions on the use of modern plant breeding techniques, biotechnology and development policy.
