Book Description
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.

Book Description
The economic importance of the stem borer in Africa results in their severe damage that affect directly cereal yield factors such as the density of fertile tillers and the number of effective panicles. The objective of this paper is to describe and discuss the management options of the main prevalent stem borer of cereal crops in Africa. Host plant resistance, cultural practices, biological control and reasoning chemical control are among the most encouraging options. Integrated pest management combining several compatible methods was highlighted as the most sustainable control option. This paper will served as support for the current research on cereal crops but also as relevant prospect document for entomologists and breeders from across the world.

Book Description
Stemborers are a major group of insect pests of cereals in Africa and Asia. They aggravate food insecurity of farmers. Non-chemical based pest management systems are advocated. Borer distribution and importance, effects of soil fertility, of indigenous cropping systems, and of planting times on borers were studied in two ecozones, i.e., the cool-humid and semi-arid regions of the Amhara State of Ethiopia. Chilo partellus, Busseola fusca, Sesamia calamistis, and a coleopterous borer, Rhynchaenus niger were found. The wasp Cotesia flavipes parasitized C. partellus. Unidentified nematodes parasitized medium sized B. fusca larvae. Increasing levels of N fertilizer increased borer density, plant growth, borer damage and grain yield (up to 74%) on sorghum. Grain losses decreased linearly from 49% at no fertilizer level to 36% at the highest N level. Intercropping maize with mustard (Brassica carinata Braun) lowered B. fusca numbers. Increasing soil nutrients increased borer attack, but also improved plant vigor, resulting in a net benefit for the plant and the grain yield. This book is ideal for pest managers, researchers, university professors and rural development workers.

Book Description
Pests Control and Acarology presents novel methods adopted in pest management for cereal crops and fruit trees. Each chapter was written by experts in their respective areas, and provides a rigorous review and outline of current trends and future needs, to expedite progress in the field. The book was structured in three sections as follows. The first section introduces the topics and defines concepts of Integrated Pest Management and Biological Control. The second section includes two chapters: the first one discusses a new trap barrier system for rodent pest control in rice and the second one presents methods used in the management of stem borers in cereal crops. The third section presents various topics within the area of Acarology.

Book Description
Annotation. Biological control has made a major contribution to integrated pest management (IPM) in Africa, but its documentation has been scattered and often under-reported. This book provides a review of the most important studies, including not only successes, but also on-going challenges. The focus is on arthropod pests and weeds, but diseases are also covered where significant. In 24 chapters, case studies and promising research results are presented that cover biocontrol by naturally occurring agents, by exotic agents or by seasonal manipulation. This book provides a valuable resource for scientists worldwide. It is particularly useful for pest control professionals working in Africa.

Book Description
Insect Pests of Millets: Systematics, Bionomics, and Management focuses on protecting the cultivated cereals that many worldwide populations depend on for food across the semi-arid tropics of the world. Providing coverage of all the major cultivated millets, including sorghum, pearlmillet, finger millet, barnyard millet, prosomillet, little millet, kodomillet, and foxtail millet, this comprehensive book on insect pests is the first of its kind that explores systematics, bionomics, distribution, damage, host range, biology, monitoring techniques, and management options, all accompanied by useful illustrations and color plates. By exploring the novel aspects of Insect-plant relationships, including host signaling orientation, host specialization, pest – host evolutionary relationship, and biogeography of insects and host plants, the book presents the latest ecologically sound and innovative techniques in insect pest management from a general overview of pest management to new biotechnological interventions. - Includes the most comprehensive and relevant aspects of insect systematics, including synonyms, nomenclatural history, and identification characters to quickly guide readers to desired information - Addresses aspects of insect-plant relationships, including host signaling and orientation, host specialization, pest – host evolutionary relationship, and biogeography of insects and host plant - Presents the latest research findings related to the ecological, behavioral, and physiological aspects of millet pests
