considered pests, and only a few of these can be a serious menace to people. Insect pests inflict damage to humans, farm animals and crops. Insect pests have been defined by Williams () as any insect in the wrong place.

Introduction. Crop losses due to pests and diseases are a major threat to incomes of rural families and to food security worldwide [1, 2].Quantitative information on crop losses and a better understanding of their drivers have been mentioned as essential to (i) evaluating the efficacy of crop protection practices , (ii) assessing systems sustainability , (iii) making better decisions for Cited by: Globally, losses from insect pests, weeds, and diseases average 35% of potential crop yields for six major crops (Oerke, ). Losses to preharvest pests are similar in vegetable crops (Dhaliwal et al., ). With commercial vegetables being valued at over $20 billion in the United States, losses and pest control costs can exceed $10 billion Author: Alvin M. Simmons, Waqas Wakil, Mirza A.

The scope of the present paper concentrates on pre-harvest losses, i.e. the eﬀect of pests on crop production in the ﬁeld, and the eﬀect Email: [email protected] of control measures applied by farmers in order to. The demands of a growing world population GLOBAL for food and fiber require farmers to produce more crops on existing farmland. To increase these yields requires continuous improvement of agricultural technologies to minimize crop losses. The challenge is to do this while TOOLS AND STRATEGIES TO protecting the environment.

Introduction. Crop losses due to pests and diseases are a major threat to incomes of rural families and to food security worldwide [1, 2].Quantitative information on crop losses and a better understanding of their drivers have been mentioned as essential to (i) evaluating the efficacy of crop protection practices , (ii) assessing systems sustainability , (iii) making better decisions for Cited by: Crop losses, or more specifically yield losses, occur because the physiology of the growing crop is negatively affected by pests in a dynamic way over time as crop both grows (i.e., increases in biomass) and develops (i.e., passes through the different stages of its physiological development).
Following an introductory chapter by J.C. Zadoks (, 27 ref.) in which the conceptual and historical basis of crop loss assessment is considered, there are chapters on the measurement of disease and pathogens (by R. Gaunt,63 ref.), measurement of insect pest populations and injury (P. Walker,50 ref.) and modelling of crop growth and yield for loss assessment (M.

Injury – The effect that the pest has on the crop or commodity. Damage – The effect that injury has on man’s assessment of the crop’s economic value.

Conference Title: Assessment of crop losses due to pests and diseases. Abstract: This volume is the proceedings of a workshop held in September, at Bangalore, and contains some 40 papers, many of a general nature.
Among crops, the total global potential loss due to pests varied from about 50% in wheat to more than 80% in cotton production. The responses are estimated as losses of 26–29% for soybean, wheat and cotton, 37 and 40% for maize, rice and potatoes, by: crop losses due to insect pest s in certain crops.
This situat ion has risen mainly due to elimination of natural enemies, resurgence of pests, developm ent of insecticide. Crop losses caused by pests, including rodents and birds, and by diseases and weeds, are defined, and previous studies reviewed.
Information about losses is needed to monitor the effects of pests and diseases on crop production, in individual countries and worldwide, important for food policy and economic reasons; to make decisions and allocate resources on the study, management and control Cited by: per cent yield losses were computed.
The data on pest incidence and yield loss for the six years were pooled to-gether to have an overall picture of the loss in yield due to pest incidence. RESULTS AND DISCUSSION. Aphid population. In – crop season, the population of mustard aphid varied from to aphids/plant in the unpro. good initial reduction in pest population at the time of treatment.
