Wakil, W. and Ghazanfar, M. U 2010. Guidelines for Pest Management Research to Reduce Stored Food Losses Caused by Insects and Mites. In the storage facility, osmophilic secondary flora is generated, which multiplies at water activities >0.7. Eggs are laid near or on the grain. Eggs and adults of a major grain pest, Rhyzopertha dominica, living inwheat (12% m.c. Reproduced with permission of FrigorTec GmgH. Eggs of the Indian mealmoth were inactivated at 110 kV. Horticultural methods: Cleaning grain stores and keeping them airtight, maintaining low temperatures (below 20°C) and hermetically sealed packaging can conserving seed viability. A review of the biology and control of Rhyzopertha dominica (F.) the lesser grain borer. In this study, samples of rough long grain rice were infested with R. … Adults of this species can live for many months or even years under optimal conditions of temperature (35 °C) and relative humidity (75%). Admixing with a grain protectant can also effectively protect sorghum and millet kernels for a relatively long time (McFarlane, 1989). The activity of these insects depends on the temperature during the storage. R. dominica is thought to originate from the Indian subcontinent, but now has a cosmopolitan distribution. Canberra, Australia, pp. Oxford: Academic Press, pp. Optimum condition for larvae is 34°C in relative humidity of 70% and moisture content of seed 14%. It is also found in temperate countries, either because of its ability for prolonged flight or as a result of the international trade in food products. 22. Interpretive Summary: The lesser grain borer, a serious pest of stored wheat, is currently managed with routine pesticide applications or … This development is prevented in the storage facility by drying and cooling rough rice. Infestations by grain weevils and Angoumois grain moth are the most reported with infestation usually commencing in the field (McFarlane, 1989; Beta et al., 2016). The Hebrew University of Jerusalem, This site is Adult weevils feed on the starch in the endosperm and larvae feed on protein and vitamin of the germ; consequently these kernels lose their germination power. Common name: Lesser grain borer, rice weevil. and Throne, J.E. The rusty grain beetle is more tolerant to cold. We use cookies to help provide and enhance our service and tailor content and ads. During processing they are typically not broken down chemically nor rendered harmless. Also, each residual insecticide is registered for certain commodities or applications. (Ed.) Contamination of food stuffs with frass, cast skins, pupal cases, and dead moths. Economic importance: This borer is a major pest of stored products throughout the tropics, subtropics, Australia and the USA. Larvae whitish with a brown head, thoractic segments broad, posteriorly narrow, elderly larvae with head and thorax recurved ventrally, about 5 mm long. Killing of insects is by freezing at −18°C or heating up to 54–66°C. The development of fungi depends on the temperature, humidity, and the grain moisture content (Fig 16.5). Table 4.5. Infestations of internal feeders such as Rhyzopertha dominica cause damage to stored grains, including rice. An adult female weevil bores a hole in the grain and lays an egg inside the kernel (McFarlane, 1989; Beta et al., 2016). Females of the maritime pine scale (Matsuccocus feytaudi) use (3S,7R)-(51) as the sex pheromone. Feed on damaged grain only, fairly resistant to high temperature, largely damaged grain turns into gray yellowish color with a moldy smell. The lesser grain borer is found throughout the tropical and also in temperate countries. Griffiths G. Atungulu, ... Z. Mohammadi Shad, in Rice (Fourth Edition), 2019. The parental culture of R. dominica emerged from paddy grains were procured from Agricultural Research Institute (ARI), Rajendranagar, Hyderabad. Primary insects are more destructive because they penetrate the grain and feed inside the grain. 22. Elisabeth Röder, ... Cornel Adler, in Reference Module in Food Science, 2017. There is little evidence that R. dominica infests wheat in the field Holes in grain and other commodities indicate insect presence, but not their specific identity. An account is given from the literature of the systematic position and distribution of the Bostrychid, Rhizopertha dominica [Rhyzopertha dominica], F., with a list of the records of its occurrence classified under zoogeographical regions. Besides aflatoxin, other mycotoxins including, citrinin, cyclopiazonic acid, fumonisins, fusarin, gliotoxin, moniliformin, ochratoxin A, patulin, sterigmatocystin, trichothecenes, and zearalenone have been reported to have contaminated rice in different studies all over the world (Lee et al., 2001; Mannaa et al., 2016). This residual insecticide has been used in several countries but is not registered for use in the United States against stored-product insects. Often multiwall paper packages or laminates of more than one material are used. It is also always accompanied with other insects such as the rice weevil, which provides entry for this insect to the grain. Geographical distribution: Cosmopolitan. Different Storage Containers and Associated Pest Control Methods. Development of various microorganisms as a function of relative (Rel.) style based on spf13 However, the insect larvae develop only inside the grain. Cribs, bins, sealed bunkers, pits, pots, bags, Underground pits, bins, tightly stacked bags. In addition, there is the metabolic activity of the pests themselves, which further promotes heat and humidity. D.S. Larvae can produce large amount of webbing and frass, which binds food together and makes it unsuitable for sale. Fumigation instantly causes pest mortality when carried out with penetrating gases for disinfestation during storage. Effects of short exposures to spinosad-treated wheat or maize on four stored-grain insects. It is not covered by patents, and the composition varies among manufacturers. Larva of this insect is very mobile and does not stay in one spot. In addition to insect resistance, many other factors need to be considered in choosing a package (see recommended reading by Brody). sci. ), Encyclopedia of Food Grains, second ed. A computer system is used for image acquisition and postprocessing. Experiments were carried out with defined developmental stages of the granary weevil (Sitophilus granarius), the lesser grain borer (Rhyzopertha dominica), as well as eggs of the Indian mealmoth (Plodia interpunctella). The male spined citrus bug (Biprorulus bibax) produces (3R,4S)-(7) as the aggregation pheromone. Most mycotoxins are heat stable and very resistant. These are insects that feed from the outer layer of the grain, though it is possible that feeding from the outside they can reach to the inside of grain (IRRI, 2013). With regard to rice, 5% of the global production is lost every year due to insect pest infestation (Xu et al., 2017). Soft electron treatment may be used to control pest insects in stored products. air humidity, temperature, and grain's moisture content (Lacey et al., 1980). X-ray images can be acquired at different voltage and current settings based on the density of the objects. 1112-1115. Attacks stored grains; is one of the most destructive and prevalent insect pests. Outdoor flight activity and immigration of Rhyzopertha dominica into seed wheat warehouses. Infestation causes distinctive off-smell in the rice. It is estimated that 1% of total rice production in the United States’ major rice growing states of Arkansas, Louisiana, Texas, Mississippi, and California is lost annually due to infestation by insects (Handbook, 1964). Controlled Atmosphere Storage of Grains, Proceedings of the International Symposium, Elsevier, Amsterdam, pp. The infestations by C. ferrugineus pupae and adults were identified with more than 96% accuracy, and 97% of kernels infested by P. interpunctella larvae were identified by both the linear-function parametric classifier and BPNN. One of the main mycotoxin-contaminating rice grains is aflatoxin, which is a toxic and carcinogenic compound produced mostly by Aspergillus flavus, Aspergillus parasiticus, and Aspergillus nomius. Damage through spinning massive amount of silk by larvae. Available at: http://gala.gre.ac.uk/10727/1/Doc-0115.pdf. Development of relevant insects dependent on temperature. Asanov, K. 1980. The adult female insect penetrates the grain and puts its seed inside the grain, then seals the hole with a gelatinous substance. Male Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae) release an aggregation pheromone consisting of a blend of two components, dominicalure 1 (D1) and Dominicalure 2 (D2). Lasioderma serricorne, Rhyzopertha dominica, and Trogoderma variabile adults and Plodia interpunctella larvae often enter packages by chewing a hole in the packaging material, while Cryptolestes pusillus, Oryzaephilus mercator, O. surinamensis, and Tribolium castaneum adults generally enter through existing holes or loose seams (see recommended reading by Cline). Astuti, L.P., Mudjiono, G., Rasminah, Ch.S. There is minimal penetration into the grain, so all but 10% of the insecticide is removed by milling and all but 1–2% by cooking. and Tribolium confusum Duv. Secondary insects can only eat on the surface of the grain. For cereals, the plastic bags inside paperboard boxes can be heat-sealed, and the glue pattern for the paperboard boxes can be chosen to maximize insect resistance. Stored product losses resulting from insect infestation are extensive and are usually associated with the occurrence of internal feeders such as lesser grain borer (Rhyzopertha dominica Fabricious) (Coleoptera: Bostrichidae) and rice weevils (Sitophilus oryzae Linnaeus) (Coleoptera: Curculionidae). These insects can cause losses in quantity and quality of the grains (Wakil et al., 2010). The pest feeds mostly on stored cereal seeds as well as on beans, ginger, cassava chips, biscuits and many others. At rural level, Neem leaves (Azadirachta indica) are also used frequently and can protect grains from over 200 insect species for up to 10 months (McFarlane, 1989). The combination of Insect growth regulators (IGRs) and entomopathogenic fungi was also effective, although some methoprene-resistant strains have been noted. Guidelines for Pest Management Research to Reduce Stored Food Losses Caused by Insects and Mites. The opposite (3S,4R)-isomer of the pheromone is also bioactive, indicating that B. bibax does not discriminate between the enantiomers.72 The male German cockroach (Blattella germanica) does not discriminate among the four stereoisomers of the female-produced sex pheromone, although the natural product is (3S,11S)-(52).73. Jayas, ... C. Karunakaran, in Computer Vision Technology for Food Quality Evaluation (Second Edition), 2016. Food odors emanating from small holes in packaging may cause females to lay eggs near or in these holes (see recommended reading by Mowery et al). Some rights reserved, This site is Susceptibility of milled rice varieties to the lesser grain borer (Rhyzopertha dominca F.). (Eds. The common laboratory-based x-ray imaging modalities are absorption imaging (based on density differences) and phase contrast imaging (based on refractive indices) (Mayo et al., 2010; Pelliccia et al., 2010). The lesser grain borer, Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae), a serious pest of stored cereal grains, is widely distributed and has been collected in different habitats in North America, such as those from agricultural and nonagricultural settings. Attacks grains especially rice; is common in flour mills. Predators and parasites of the lesser grain borer. During warm seasons insect populations increase more rapidly; optimum temperatures for these insects are 32–35°C. This technology may be an efficient physical alternative for stored product protection in grains, legumes and spices. Table 16.3. For insects that bury their larvae into the grain, the grain dimensions of length and thickness as well as tightness of hull are important for infestation (Juliano, 1981). The concept of automation of the system to image single grain kernels has been demonstrated (Melvin et al., 2003). Photo Courtesy: Canadian Wheat Board Centre of Grain Storage Research, University of Manitoba, Winnipeg, MB, Canada. Various insects have different abilities to bore into the kernel. At 34°C complete development requires about 3 weeks and humidity content of above 9%. Fundamentals of Stored-Product Entomology. Pirimiphos-methyl is responsible for controlling weevils and other pests through its fumigant activity, while permethrin controls the larger grain borer through its contact and stomach activity (http://www.twigachemicals.com/products/actellic-super-dust/). industr. The linear-function parametric classifier and back-propagation neural network (BPNN) identified more than 84% of infestations caused by C. ferrugineus and T. castaneum larvae (Table 16.3). A total of 57 extracted features were used to identify uninfested and infested kernels using statistical and neural network classifiers (Karunakaran et al., 2003a,b,c, 2004b,c,d,e). 79–84. Studies on the oviposition of Rhyzopertha dominica (F.) in rice and paddy - Volume 53 Issue 4 - Michael H. Breese Economic importance: This borer is a major pest of stored products throughout the tropics, subtropics, Australia and the USA. Pronotum tuberculate and elytra with punctate, parallel-sided striations. It is considered to be second in importance to Sitophilus oryzae as a destroyer of stored grain. The pest cannot develop below 20°C or above 38-40°C. Methyl eugenol was demonstrated to possess insecticidal activity against maize weevils and red flour beetles, American cockroaches (Periplaneta americana) and mold mites (Tyrophagus putrescentiae). An insect can generate several thousand offspring in 1 year. Host plants: Polyphagous, especially cereal seeds. The males produce a pheromone that attracts both genders. Optimum temperature is 35°C and relative humidity of 75%. A summary of methods used for pest control is provided in Table 4.5. The pest feeds mostly on stored cereal seeds as well as on beans, ginger, cassava chips, biscuits and many others. Images formed on the x-ray fluorescent detection screen are captured by a charge-coupled device (CCD) monochrome camera and digitized into 8-bit gray scale images at a spatial resolution unique to the system. Histogram features, histogram and shape moments, and textural features using co-occurrence and run-length matrices were extracted for each kernel from the x-ray images. Two types of x-ray imaging are generally used in the agri-food industry: soft x-rays with 10 to 0.6 nm wavelength with low energy and less penetrating power and hard x-rays with 0.6 to 0.01 nm wavelength with high energy and more penetration power. The same was multiplied on the maize hybrid, DHM - 111. Many plastic films or foils provide better insect resistance than paper or cellophane. Insect pests may also be classified based on their morphology. Inactive when it is completely dark, mainly active at dawn and dusk, attack the grain embryo and leave a thick web grain surface, can cause 10% losses or more. Differential natural performance of four Cheyletus predatory mite species in Czech grain stores. Taxonomic placing: Insecta, Holometabola, Coleoptera, Bostrychidae. Journal of Economic Entomology 103: 197-202. Optimum moisture content of the grain for development of insects is 12%–14% at temperature 26–34°C.

Guidelines for Pest Management Research to Reduce Stored Food Losses Caused by Insects and Mites. Metwaly, M.R., Abou-Ghadir, N.M.F., Abdu-Allah, G.M. Classification accuracies of CWRS wheat kernels uninfested and infested by stored-grain insects using BPN and linear-function parametric classifier using all 57 features (Karunakaran, 2002). The importance of Rhizopertha dominica as a pest of wheat under wartime storage conditions.—J. Technical Abstract: The importance of the storage of sorghum increases as the demand grows for sorghum as a substitute for gluten-based products. 1994. The average lifespan of a weevil is about 5–6 months (McFarlane, 1989; Beta et al., 2016). Jing-Kun Miao, ... Qi-Xiong Chen, in Essential Oils in Food Preservation, Flavor and Safety, 2016. Damaging the seed germ reduces germination rates and may be followed by secondary pests and fungi. These machines can scan grain kernels at the rate of 60 g/min like a continuous machine vision system that captures color images of grain for identification (Crowe et al., 1997). CABI Distribution Maps of Pests, Series A, Agricultural Map #318, 1973. The Food and Agriculture Organization of the United Nations (FAO) recommends the use of phosphine as a fumigant for insect control. Insect in pupa stage is immobile in the grain and does not feed. 2012. Kenji Mori, in Comprehensive Natural Products Chemistry, 1999, Dominicalure 1 ((S)-(49)) (Figure 10) and dominicalure 2 ((S)-(50)) are the male-produced aggregation pheromone components of the lesser grain borer, Rhyzopertha dominica. 22. Sieving grain samples for adult presence. Athanassiou, C.G., Arthur, F.H. At 25°C and 75% relative humidity, the female insect starts laying eggs. Adults of C. pusillus, L. serricorne, O. mercator, and T. castaneum are better penetrators than larvae. A complete control is expected at 270 kV. Insects and mites multiply explosively under favorable conditions. The insects also produce bad smell in heavily infested crops, which is not acceptable by consumers. Journal of Economic Entomology 103: 977-984. 2010. Hagstrum (2001) showed that R. dominica and other stored-product pests can immigrate into grain bins through the * Edde, P.A. Copyright © 2021 Elsevier B.V. or its licensors or contributors. Powered by Hugo by It is a serious pest of stored products throughout the tropics, Australia and the USA. The insect's life cycle at 28°C and relative humidity of 70% is 35 days. The lesser grain borer Rhyzopertha dominica (Fab.) research findings on R. dominica are presented to show how these broader landscape issues might be important in understanding and managing this pest. Primary insect pests are those whose larvae feed inside the kernel. The pest is susceptible to spinosad. Entomologia Experimentalis et Applicata 121: 73-85. The But industries are at present working toward creating such a system where these machines would be able to scan singulated grain kernels to detect insect infestations (Karunakaran et al., 2004a). Adult insect can lay 45 to 285 seeds during a life cycle.

Freitas 3, Irineu Lorini and João B.R. and Rahardjo, B.T. Artificial infestations by different life stages of Cryptolestes ferrugineus (Stephens), Tribolium castaneum (Herbst), Plodia interpunctella (Hubner), Sitophilus oryzae (L.), and Rhyzopertha dominica (F.) in CWRS wheat kernels were created. From: Journal of Stored Products Research, 2012, David W. Hagstrum, Bhadriraju Subramanyam, in Fundamentals of Stored-Product Entomology, 2006. In a rice storage facility, various types of insects are encountered. Control by heat treatment: A thermal method for the disinfection of post-harvest pests consists of high temperature treatments. Fungi on the grain can produce mycotoxins, some of which have toxic effects on humans and animals. For this reason, the formation of toxins must be prevented by preventing harmful fungi from forming and proliferating on rice during storage. dedicated to the memory of Chlorpyrifos-methyl was registered for use on barley, oats, rice, wheat, and sorghum, and pirimiphos-methyl is currently registered in the United States for use on maize, popcorn, and sorghum. Adapted from McFarlane, J.A., 1989. Table 16.2. Essential Oils in Food Preservation, Flavor and Safety, Computer Vision Technology for Food Quality Evaluation (Second Edition), Mayo et al., 2010; Pelliccia et al., 2010, Neethirajan et al., 2006, 2007; Karunakaran and Jayas, 2014. and Tsiropoulos, N.G. Larval feeding inside the grains produces big holes in the grain. β-asarone also exhibited insecticidal activity against S. zeamais, R. dominica, T. castaneum, and Callosobruchus maculatus. The linear-function parametric classifier and BPNN performed better than the quadratic-function parametric and nonparametric classifiers for the identification of infested kernels by different insects.
