Download Applications of gamma rays for the control of some major stored grain pests
The gamma ray method is used in post-harvest pest control because the rays have the ability to penetrate deeply into pallet loads of food (Morrison, ).Cited by: The efficacy of 16, rads, recommended for industrial applications of gamma radiation for the control of insects in grain, is substantiated by the complete sterilisation and death of 10 million insects of a wild strain of grain weevil under conditions simulating bulk storage.
The germination of wheat grain was lowered after treatment with microwave radiation but was not affected by a dose of 1 KGy gamma ghts► A means to control grain.
Food irradiation uses radiant energy electron beams, gamma rays or x-rays to rid food of harmful microorganisms, insects, fungi and other pests, and to retard spoilage.
It does not make food radioactive. Irradiation kills pathogens and makes them incapable of reproduction. The work reported in this volume was carried out by the Entomology Group of the Wantage Research Laboratory in This group was established as part of the contribution of the United Kingdom Atomic Energy Authority to the finding of possible industrial applications of the new sources of radiation now available.
The book contains a foreword by H. SELIGMAN, an introduction by the Editor Cited by: 3. Several species of beetles and moths can attack stored grain. The damaging life stages of beetles include larvae and adults, while damage from moth pests tend to be caused by larval stages.
Proper identification of pests is essential for effective control. Some common stored grain pests are described at the end of this article. of stored grain. Almost all the insect pests of stored grain have a remarkably high biotic potential and within one season, they may destroy % of the grain and contaminate the rest with undesirable odour and residue.
Dampness of the receptacles as well as seed grain also promote the growth of certain fungi on cereals and other grains. In Montana, almost all stored-grain insects are beetles and weevils in the Order Coleoptera.
There are rare occurrences of moth pests (Lepidoptera). Members of seven other insect Orders are also found in grain storage throughout the world, but the major pests are still primarily from the. Stored Grain Insect Reference September Page 6 Granary Weevil The granary weevil, Sitophilus granarius (Linnaeus),1 is a small, moderately polished, blackish or chestnut-brown beetle (fig.
1A). The head emends into a long slender snout with a pair of stow. Published: October 3, Insect problems in stored grain are best prevented through sound grain management at the on-farm level.
Implementation of sanitation practices which reduce residual pest insect numbers in empty bins and grain handling equipment coupled with pre-harvest insecticide applications to empty bin surfaces and surrounding areas is the first step in effective.
The basic components of an irradiation unit (gamma-ray or electron) are composed of the following: (1) the control systems related to radiation source are referred as “irradiators,” (2) a product transport system, Applications of gamma rays for the control of some major stored grain pests book (3) a shielding for protecting human health and environment from radiation.
Two major types of irradiator are “self. ABSTRACT Article History Management of stored-grain insects using gamma radiation could be enhanced by other feasible control methods such as essential oils as potential alternatives to chemical.
Facts & Information on Stored Grain Insects. Stored Grain Management Options-- From K-State Research and Extension; Top 10 Stored Grain Management Tips-- From Joe Harner, Extension Engineer; Stored Grain Advisor (SGA) is a decision support system for stored grain helps you make decisions about managing insect pests in stored wheat.
The gamma ray method is one of most commonly used in postharvest pest control because of the gamma ray ability to deeply penetrate pallet loads of food. Nuclear energy also can be used for development of new quality product which can give more throughputs and quality product.
Biological control of stored product pests: Biological control is an over-looked component of integrated pest management of stored product pest (Flinn et al., ). Many species of insect natural enemies occurs in stored product ecosystem (Brower et al., ) and these species represent potential biological control agents for the desired pests.
the target insect. Traps for some pests are coated with an adhesive that also contains the chemical attractant. Stored-product insects can be detected with a variety of traps, some using food attractants or synthetic insect pher-omones (Vick et al., ). Three stored-product insects that commonly occur together, and for which pheromones.
There are about different pests that are associated with stored products, mostly from two different orders: Lepidoptera (butterflies and moths) and Coleoptera (beetles) (Boyer et al. ; Sallam ).Coleopterans are some of the main pests of stored products (Stejskal et al.
), feeding on the product throughout both larval and adult stages, which results in great economic losses. Insect infestation in stored grain is fostered by moisture, moderate heat, and damaged kernels. Not only does high moisture content in grain and processed food provide a favorable physical environment for development of many pest species, it also fosters the development of the molds on which some.
Stored products of agriculture and animal origin are attacked by more than species of beetles, 70 species of moths, and about species of mites, causing huge quantitative and qualitative losses and insect contamination in food commodities.
This is an important quality control problem. This book, Insect Pests of Stored Grain: Biology, Behavior, and Management Strategies, provides. Food irradiation is the process of exposing food and food packaging to ionizing radiation, such as from gamma rays, x-rays, or electron beams, without direct contact to the food product.
Food irradiation is used to improve food safety by extending product shelf life (preservation), reducing the risk of foodborne illness, delaying or eliminating sprouting or ripening, by sterilization of foods.
Application of ionizing radiation using gamma rays can serve many purposes, such as eliminating organisms that cause food-borne illness, destroying organisms that cause spoilage and decomposition, controlling quarantine insects to prevent their spread, inhibiting sprouting and delaying ripening and de-contamination of food commodities.
This book, Insect Pests of Stored Grain: Biology, Behavior, and Management Strategies, provides comprehensive coverage of stored product entomology for the sustainable management of insects and other noninsect pests, such as mites, birds, rodents, and fungi, with the aim to mitigate and eliminate these losses of food from grains.
Stored grain insect infestations rarely begin in the field. Most develop from small numbers of pests already present in or around farm storage bins. An effective sanitation program can eliminate or greatly reduce the chance of having serious problems with these insects.
Equipment: Grain handling equipment should be kept clean. Once the grain temperature and the outdoor air temperature are below 45 F, monthly monitoring should be adequate. If the average grain or air temperature is above 45 F, inspect every 2 weeks.
Be observant. Many stored grain problems can be stopped in the early stages if you are paying attention. Odor is a common indicator of grain spoilage. A pocket reference that allows the non-specialist to identify major insect and arachnid pests found in stored cereal grains, grain products and grain legumes.
It describes most storage pests found worldwide and provides concise information on the biology, distribution, damage and economic importance of each species. Each entry contains at least one color photograph.
PESTS OF STORED PRODUCTS A ‘pest of stored products’ can refer to any organism that infests and damages stored food, books and documents, fabrics, leather, carpets, and any other dried or preserved item that is not used shortly after it is delivered to a location, or moved regularly.
Insects and pests constitute a major threat to food supplies all over the world. Some estimates put the loss of food grains because of infestation to about 40% of the world production. Contemporary disinfestation methods are chemical fumigation, ionizing radiation, controlled atmosphere, conventional hot air treatment, and dielectric heating, that is, radio frequency and microwave energy, and.
The current emphasis upon integrated pest management is, in effect, a reassertion of the need to put traditional good husbandry in place as the fundamental basis of pest control. In grain storage, as with other durable agricultural products, it is good commodity management and good store management which are the major prerequisites (Tables Aeration — blowing ambient air through grain storage bins — has been used for decades to maintain the quality of grain by keeping it cool, as well as to manage stored insect pests.
But few recent studies have examined whether it’s better to direct air from above or below as a means of using temperatures of 60 degrees Fahrenheit or below.
Even in cold storage (at °C) some, at least, of the important insect pests of stored grain can survive longer than one year (Wohlgemuth, ). Insects require oxygen for respiration. Living grains, when sufficiently dry (% me), are dormant and respire very little. Stored grain pests account for a significant amount of loss every year in the agricultural sector.
Handlers of dry agricultural commodities know the extent of damage that these various insects can bring, such as the lesser grain borer’s tendency to decimate stored grains or. a surface treatment for grain and to control stored product pests (Faruki et al., ).
Gamma rays from the isotopes cobalt ( and MeV) and cesium ( MeV) may be used for food. Cobalt is bred from standard (nonradioactive) cobalt (atomic weight ) via neutron irradiation.
It has a half-life of years. At the end of each major section is a list of study questions to check your Control of stored-product pests is necessary to prevent contamination/ adulteration of human foods. Persons some parts of the grain mass remains above 15˚C (60˚F) until October through January.
In general, as grain. Grain is protected from re-wetting by rain or imbibing moisture from the surrounding air. The longer the grain needs to be stored, the lower the required moisture content will need to be.
Grain and seed stored at moisture contents above 14% may experience the growth of molds, rapid loss of viability and a reduction in eating quality. Biological control methods for insect pests of stored grain in the tropics-constraints and prospects for developing countries R.

Effect of gamma radiation on the inactivation of Aflatoxin B1 in food and feed crops CASE STUDY 4 Ghanem et al., MATERIALS AND METHODS • Inoculation with the fungus • Irradiation with gamma ray-4, 6, and 10 kGy • Irradiation source-Cobalt serious pests of stored grain have become cosmopolitan in distribu bution.
Nevertheless, the civilized world insists more and more on grain delivered free from insect infestation. Grain stored in a large quantity is usually cared for better than the same amount of grain in a number of smaller lots (as on farms).
Even so, quantity storage. Hanif et al. assessed the repellent and mortality efficacy of essential oils obtained from some indigenous plants such as bakain, neem, and datura against some important stored grain pests like T.
castaneum, R. dominica, and T. granarium and found a 76% to 81% repellence to these compounds by insects and 24% to 28% mortality. SAMPLING AND BIOSTATISTICS Identifying Stored-Grain Insects Using Near-Infrared Spectroscopy F. DOWELL, J. THRONE, D. WANG, AND J.
