The legume pod borer, Maruca vitrata, causes severe damage on legume crops in the tropics. The larvae are mainly controlled by synthetic insecticides but without satisfying results. Monitoring of the moths using pheromone traps can help to perform target-oriented control measures. The objective of this study was the improvement of pheromone traps for monitoring M. vitrata in tropical Asia, where synthetic pheromone lures failed to attract males so far. In addition, the sexual communication system of different M. vitrata populations was investigated, since variation in pheromone composition is a potential reason for failure of pheromone lures.

Cowpea, Vigna unguiculata (Linnaeus) Walpers [Syn. Vigna sinensis (Linnaeus)] is one of the pulses belonging to family Fabaceae/Papilionaceae and sub-family Faboidae/Papilionoidae and also known as black-eyed bean or southern pea in English while chola or choli, chavli, lobia in vernacular languages in India. It is the most versatile kharif pulse because of its drought tolerating characters, soil restoring properties and multipurpose uses. Cowpea is called vegetable meat due to high amount of protein in grain with better biological value on dry weight. Cowpea grain contains 60% carbohydrates, 22-28% protein and 1.8% fat. Moreover, it is a rich source of calcium and iron . It is grown as a green manure for soil improvement. It contains 54 kg N/ha in tops and 49 kg N/ha in roots. The crop forms excellent forage. The feeding value of cowpea is high and quite comparable to lucerne.Spotted pod borer, M. vitrata feeding on flowers, pods and leaves is one of the major insect pest of cowpea in tropics. It is reported that larval stage of insect can destroy the flowers and developing pods to an extent of up to 60% in tropics and sub-tropics

This book comprehensively compiles information on some of the major pests that afflict agricultural, horticultural and medicinal crops in particular as well as many polyphagous pests. Not only does this book deal with the pests of common globally produced crops it also addresses those of rarely dealt with crops such as seed spices, medicinal and aromatic plants. While the perspective of insect pests is largely Indian and South East Asian in context, the book does deal with globally problematic pests, particularly polyphagous ones. Not only will the readers be acquainted with the pests, their damaging potential and their life cycle but also with the latest methods of managements including ecofriendly measures being employed to keep pest populations at manageable levels. The 27 chapters in the book, are grouped into four sections primarily based on crop types, viz. pest of agricultural, horticultural and medicinal crops, and polyphagous pests, making the book easy to navigate. Each of the chapters is comprehensive and well illustrated and written by academicians who have dedicated their entire lives to the study of a particular crop-pest complex. The final chapter of this book provides an overview on the principles and processes of pest management.

This book presents state-of-the-art, authoritative chapters on contemporary issues in the broad areas of quantitative genetics, genomics and plant breeding. Section 1 (Chapters 2 to 12) emphasizes the application of genomics, and genome and epigenome editing techniques, in plant breeding; bioinformatics; quantitative trait loci mapping; and the latest approaches of examining and exploiting genotype-environment interactions. Section 2 (Chapters 13 to 20) represents the intersection of breeding, genetics and genomics. This section describes the use of cutting-edge molecular breeding and quantitative genetics techniques in wheat, rice, maize, root and tuber crops and pearl millet. Overall, the book focuses on using genomic information to help evaluate traits that can combat biotic/abiotic stresses, genome-wide association mapping, high-throughput genotyping/phenotyping, biofortification, use of big data, orphan crops, and gene editing techniques. The examples featured are taken from across crop science research and cover a wide geographical base.

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.

Since oil prices’ decline in 2014, agriculture has received renewed interest in Nigeria as a key sector for achieving sustainable growth and generating foreign exchange. One of the identified obstacles to achieving these goals is the need to improve agricultural productivity. Cowpea is one of the priority crops identified for productivity improvement. Currently cowpea yields are below 900 kg/ha, but it has been shown that with the right technology, these yields could potentially double. One of the main biotic constraints for cowpea is the infestation of the insect pod borer (Maruca Vitrata). No conventional variety has been developed to resist this pest, but with the use of biotechnology and the sustained collaboration of national and international partners over many years, there is now a genetically modified pod-borer-resistant (or more generally insect-resistant) cowpea. This paper estimates the potential economic benefits of adopting this new technology and the cost that Nigeria will incur if this adoption is delayed. The analysis is conducted using an economic surplus partial equilibrium model run with the newly developed DREAMpy software, data drawn from the Nigeria General Household Survey 2015–2016, estimations using these data, and other local sources. The estimations show that if the insect-resistant cowpea is planted in 2020, the net present-value benefits for producers and consumers would be around US$350 million, 70 percent of which would be accrued by producers. The distribution of benefits by region show that Sudan-Sahel will accrue the most benefits, given the relative concentration of cowpea in this region and the estimated higher adoption rates and yield changes. Almost half of producers’ total benefit will go to large producers, who represent only 20 percent of all cowpea producers, while small producers, representing half of all cowpea producers, will receive 24 percent of the benefit. Additionally, the analysis shows that a five-year regulatory delay will decrease the estimated benefits by around 35 percent. While Nigeria already has in place a competent biosafety system that will most likely ensure that these regulatory delays will not materialize, these estimations highlight the importance of having an evidence-based, efficient, predictable, and transparent regulatory system to ensure that the expected economic benefits are realized.
