Population Dynamics and Management of Pod Borer Complex in Pigeonpea


Book Description

Investigation on population dynamics and management of pod borer complex in pigeonpea were carried out at Anand Agricultural University, Anand during Kharif 2007-08 and 2008-09. The studies on population dynamics indicated the significant negative association between larval population of Helicoverpa armigera (Hub.) as well as Exelastis atomosa (Wals.) and bright sunshine hours as well as evaporation. The significant positive association was found between larval population of Melanagromyza obtusa Malloch and wind speed. Whereas, significant negative association was found between larval population of M. obtusa and maximum and minimum temperature, morning and evening vapour pressure and evaporation. There were non-significant effects of weather parameters on larval population of Lampides boeticus L. The early maturing determinate cultivars with green pods and high total soluble sugar, protein, amino acids and chlorophyll as well as low phenol and tannin were found more susceptible to H. armigera, E. atomosa and L. boeticus. Early maturing determinate types cultivars with brown striped pods were found less susceptible to M. obtusa. Early sown pigeonpea was more proned to H. armigera.




Studies On Population Dynamics & Management Of Heliothis In Chickpea


Book Description

The higher acreage and low productivity in chickpea depends on number of constraints, among them insect-pest has been recognized as one of the constraints. Among various insect-pests of chickpea Helicoverpa armigera is one of the most important biotic constraint, the damage caused during flowering and pod formation stages results in substantial yield loss. Chickpea is most preferred host of H. armigera, and it suffers losses to the tune of 20-80 % The pest can be managed by spraying the insecticides at the economic threshold level. As such, some modern trends are aimed for finding effective but safer insecticides that can be used in conjugation with bio-agents (NPV, Bt.), botanical insecticides (NSKE, Azadirachtin) so as to regulate pest population within economic limit and In order to minimize the adverse consequences of the pesticides there is dire need to develop eco-friendly management practice for this pest, which could be done by studying the seasonal incidence of the pest on chickpea. In the present study both the aspects of managing Helicoverpa had been undertaken, so that in future we may develop an integrated approach towards management of this noxious polyphagous pest.

Antimicrobial Resistance in Agriculture and its Consequences


Book Description

This book offers comprehensive coverage of all manifestations of resistance in combating infectious diseases and explores advances in antimicrobial resistance in agriculture and their applications in the fight against microbes. It discusses and compares biological, biochemical, and structural aspects of resistance and its evolution. This is a comprehensive tool covering all manifestations of antimicrobial resistance and microbial resistance genes. In addition, it also provides a variety of photographs, diagrams, and tables to help illustrate the material. Novel strategies to combat antimicrobial resistance are also described, emphasizing collaborative measures of control. The underlining molecular mechanisms, which depend not only on the microbe but on the specific drug (target) molecule, are highly diverse and are covered in great detail. Students, researchers, scientists, practitioners, academics, computational biologists, stakeholders, and policymakers can benefit from using Antimicrobial Resistance in Agriculture and its Consequences as a resource that addresses microbial biotechnology, microbiology, ethnopharmacology, toxicology, medicinal plant products, and all disciplines related to antimicrobial research. Features of the book: Covers antimicrobial resistance in agriculture with up-to-date research Includes recent references on each plausible antimicrobial resistance in agriculture Details the possible spread of antibiotic resistance bacteria from animals to humans Provides several perspectives in the resistance flux with modern agricultural practices Describes the public health impact of the use of antibiotics in agriculture Presents cutting-edge research on epigenetics, nanotechnology, and emergent antimicrobial technologies Outlines recent laws and regulatory guidelines in the federal agency, responsibility, and authority







Pests and Their Management


Book Description

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.




Management of Gram Pod Borer in Chickpea


Book Description

Chickpea (Cicer arietinum L.) the most common pulse crop, is exposed to attack by many insect pests, amid them Helicoverpa armigera is the major limiting factor for higher yield of the crop. Thereby a field experiment has been carried out to develop an effective pest management strategy for the crop. Side by side a laboratory experiment has also been conducted to study the growth and development of 3rd instar larvae of H. armigera along with the level of parasitization at natural condition. The finding revealed no significant difference in mean larval length, larval and pupal phases as well as pupal weight in different chickpea cultivars. The varietal screening for both years of the study revealed that BG-256 was less vulnerable to H. armigera. The efficacy of different bio-pesticides was evaluated against H. armigera in chickpea. The larval population was significantly lower in spinosad 2.5 SC @ 0.5 ml/l. The field experiment on the relative ability of various insecticides against H. armigera revealed that indoxacarb 14.5 SC @ 0.5 ml/l as the most effective one. Intercropping chickpea with linseed (2:2) resulted in lower larval populace and less pod damage for both years of study.
