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 colour photograph. The notes for each species tell the nature of the pest or beneficial and the commodity affected; temperature and humidity conditions at which the species can survive; optimum conditions at which eggs take the shortest time to develop into adults; and maximum population growth rate per month. This new edition has twice as many species in it and more detail on distribution, host range and pest status than the previous edition. Short introductory sections on insect biology, principles of control and concepts of pest status evaluation have also been added.

Cereals are an essential part of the diet of Homo sapiens. Since late Neolithic times, with the transition to sedentary farming, working with grain (growing, storing, processing, cooking food) has become a traditional type of professional human activity. As part of the accumulated historical experience, numerous technological processes have been developed and optimized for this type of activity. The relevant technologies evolved in close correlation with the changing conditions of life, literally under the pressure of Darwinian natural selection, because they were directly related to the survival of the Homo sapiens. Further development of grain-processing technologies remains invariably urgent today, as evidenced by the report [1] presented by the UN on the state of food security and nutrition in the world - with horrifying figures depicting the need and misery of the wide masses of the population of the planet. An important component of grain processing is the technology associated with the storage of grain products. Part of the stored grain products is used as seed stock for a new cycle of grain sales, the other - a significant part - for processing into food products. At the same time, new developed (optimized, improved) grain storage technologies must be safe, low-cost, maximally compatible with previously developed (available) equipment, and scalable to large volumes of stored material. Of course, the technology must ensure proper efficiency, an indicator of which should be a reduction in the percentage of grain product losses. In this regard, management methods used in the technological processes of grain products storage are substantially important, as well as methods of control over the current state of grain products for the correct organization of the technological processes. In particular, methods using elements of artificial intelligence are of high interest. Among them, neural networks are promising, especially those capable of learning "without a teacher" - Kohonen Maps (KK). Modified KK algorithm [2] implements reduced learning time[3], which is relevant in the implementation of adaptive procedures for processing the results of measurements of controlled parameters. The purpose of this paper is to consider the principles of using modified Kohonen maps to classify situations with applicability to remote quality control of grain products storage.

Growth And Reproduction

Hot spots may develop quickly in farm stored grain under Canadian winter conditions. Heavy infestations of mites, insects and fungi may accompany such hot spots (Stirrett and Arnott, 1933; Watters, 1955). Once the heating process is initiated, whatever its cause, it brings about a rapid deterioration of grain, tluough charring of kernels, and reduction of their germinability, and by providing optimum conditions for the growth and reproduction of storage fungi, insects and mites.

Mungbean is one of the most important grain legumes with high-quality dietary protein in India as well in many other Asian countries. But the crop is severely affected by bruchids (Callosobruchus spp.) from field to storage condition. These storage pests not only affect the yield but also reduce the market value and quality of the crops. The chemical method of bruchid management is not economical and environmentally unsafe. So, the host-plant resistance to bruchids would be the best alternative and most sustainable way to control the bruchid. A very limited number of wild accessions and cultivated genotypes are available for the transfer of bruchid resistance gene through conventional breeding. Thus, insights into the molecular mechanism of resistance will help to find out the resistance genes/QTLs easily with the support of available genome sequence and that can be introgressed to the cultivated varieties through marker-assisted backcross breeding (MABB) approach. Therefore, in this review, we focused on QTL mapping, identification of novel QTLs, marker assisted-selection, genomics and transcriptomics study by using advanced molecular tools which will be very helpful for genomic-assisted breeding in mungbean for bruchid resistance.

Pteromalus Cerealellae

Consumers are increasingly demanding pesticide-free grain/legumes and processed foods. Additionally, there are more restrictions, or complete loss, of insecticides labelled for use in managing stored grain insects in post-harvest ecosystems. Suppression of post-harvest pests using parasitic wasps is a more sustainable alternative than chemical pesticides. Habrobracon hebetor (Say) (Hymenoptera: Braconidae) and Pteromalus cerealellae Ashmead (Hymenoptera: Pteromalidae) are two important parasitoids that limit economically important pests of stored products. Host searching ability and reproductive performances of H. hebetor and P. cerealellae depend on a wide range of factors, such as host species, commodities, and environmental conditions. Further, use of entomopathogens can complement the ability of parasitoids to regulate pest populations. This review provides information on aspects of H. hebetor and P. cerealellae biology and successful regulation of post-harvest pest populations.

Abstract A description is provided for Mucor pusillus[Rhizomucor pusillus]. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On soil, air, mushroom compost, stored barley, fermenting cacao, bagasse, birds' nests and pathogenic to man and other warm-blooded animals (causing mycoses). DISEASE: Plants: causes storage rot and subsequent loss of stored grain which can be controlled by preventing heating of grain by adequate drying and ventilation and prevention of storage pests which often initiate heating and subsequent moulding. Man and animals: A commonly reported cause of phycomycosis in man and other warm blooded animals. It has been recorded from infections of many organs of the body including the alimentary tract, brain, heart, lungs, lymph nodes and nasopharynx of various hosts. The host range includes man (RMVM 2, 690; 9, 984, 469), cattle (RMVM 9, 473; 10, 1970), dog, harp seal (RMVM 3, 1664), horse (RMVM 3, 1249), pig, sheep (Borodenok, 1961) and wild fowl. It also causes mycotic abortion in cattle. It has been used in studies on experimental phycomycosis in mice (RMVM 3, 1566; 2, 1916), rabbits (RMVM 7, 4027; 2, 690), guineapig (RMVM 2, 690) and fowl (RMVM 7, 863). GEOGRAPHICAL DISTRIBUTION: Probably world-wide. TRANSMISSION: By air-borne spores.

Pest Status

A survey determined the extent and severity of the infestations of four species of Carduus thistles in the United States. In the mainland United States, 360 counties of 3068 have economically important infestations of musk thistle (Carduus nutans L.), the Appalachian and midwest regions harboring the greatest infestations. Plumeless thistle (Carduus acanthoides L.) and Italian thistle (Carduus pycnocephalus L.) are of economic importance, but have limited distribution. Welted thistle (Carduus crispus L.) is approaching pest status only in Virginia.
