Atlas of Stored-Product Insects and Mites

Chapter 1


As well as a bound collection of maps, an atlas can be defined as a book of photographs or tables covering any subject. High quality insect photographs in Atlas of StoredProduct Insects and Mites will be useful in making an initial insect identification so that an appropriate taxonomic key can be selected to confirm the identification of an insect species. The book has 7 chapters. Chapter 2 has insect photographs and summary information for each of the 235 insect species that add to the photographs given in Nawrot and Klejdysz (2009) book and the information in Hagstrum and Subramanyam (2009a). The insect species photographed were 235 out of 1663 species that were ranked highest as stored-product insect pests. Chapters 3, 4 and 5 expand upon the summaries in Chapter 2. Chapter 6 provides summary information for 280 species of mites (Acari) reported to be associated with stored products similar to the summary information provided for insects. Chapter 7 discusses tools and information that need to be considered when developing a pest management program for stored-product insect pests and shows where additional information can be found. For a good example of a monitoring-based pest management program developed for stored wheat insect pests see Hagstrum et al. (2010). Popular literature which is infrequently cited in the scientific literature can be more user friendly and provide an industry perspective of pest problems and solutions. For an overview of useful popular literature on stored-product insect pests and their management see Hagstrum and Subramanyam (2009b). The Atlas will be useful to students, extension personnel, consultants, food industry sanitarians and managers, legislators, regulators, plant quarantine inspectors, storedproduct entomologists, urban entomologists, seed technologists and pest management professionals, and will be an

essential desk reference for anyone working with storedproduct insects or mites. Atlas of Stored-Product Insects and Mites includes more stored-product insect and mite common names, synonyms for stored-product insects and mites scientific names, geographic distribution records and literature citations for life histories studies than other books. The commodities infested by insect species are classified into 28 categories and research on the suitability of commodities as insect food is summarized. Literature references are provided for each record of a commodity infested by an insect species. These literature references may help the readers decide whether a commodity is likely to be a suitable host for a pest species. Atlas of Stored-Product Insects and Mites shows the diversity and geographic distribution of stored-product insect and mite species, and will make solving stored-product pest problems easier by making essential information more readily available.

Chapter 2

Stored-Product Insects

A full listing of the abbreviations used in Table 2.2 is given in Table 2.1. Photographs of the adults of 235 species storedproduct insects and information on these species are included in Table 2.2. For a few of these species, pictures of male and female are included to show the sexual dimorphism. Wingspan is given for most Lepidoptera and body length is given for the other species. Much of the text in Table 2.2 is from Hagstrum and Subramanyam (2009) with some summarization and updating. In addition to English common names, French (F), German (G), Russian (R) and Spanish (S) common names are provided for many species. Common names are reported for 26.8% of the the 235 species of insects. Table 2.3 shows the countries or islands in each of seven geographical regions for which insect records are reported here (see Hagstrum and Subramanyam 2009 for a list of countries for each species). More countries or islands are included for some regions than for others, i.e., Africa (Af, 61), Asia and Middle East (As, 58), Central America and Caribbean (C, 34), Europe (E, 65), North America and Mexico (N, 3), Oceania (O, 24), South America (SA, 18). The extensive geographical distribution records provided in LÜbl and Smetana (2003, 2004, 2007, 2008, 2010) for Coleoptera and Roesler (1973) for Lepidoptera have resulted in disproportionately more records for Europe, North Africa and Asia. Published records are likely to be incomplete and may underestimate a species’ geographic distribution. Also, more studies have been done in some countries than in others. Some of the records may be in error, and in other cases, a species may be present only for a limited time and may not become permanently established. Many of the localities with low numbers of species reported are small, sparsely populated islands or small countries. This may be the result of less international trade. Among geographical regions, the average number of species reported per country was highest for the North

American region (132.0) and lowest for South American islands (1.4) (Table 2.3). Records from 158 mainland countries and 106 islands are included. The majority of these records (7710 out of 9262) were from mainland countries. The numbers of species reported for mainland countries were generally two or more times higher than those reported for islands. The number of species reported for Japan, New Zealand and United Kingdom (England, Ireland, Scotland and Wales) were more like those reported for mainland countries than those reported for islands, so these islands were included with the mainland countries. Some records reported species to be present in Indonesia or West Indies, while others reported their presence on individual islands of these island groups, so both kinds of records are included. Also, some records report species to be present in Yugoslavia, while others report their presence in countries into which this country has been divided, so both kinds of records are included. The species list for nine countries that have reported large numbers of stored-product insect species are compared (Table 2.4). The countries with the largest number of species on each continent were selected because they are likely to be the countries in which stored-product insects have been most thoroughly studied. Egypt and Nigeria represent northern and southern Africa. England and Italy represent different parts of Europe. Twenty three species have been reported for all nine countries, 52 from eight, 82 from seven, 110 from six, 139 from five, 174 from four, 194 from three, 212 from two and 234 from one. Pharaxonotha kirschii was not reported in any of the nine countries. The largest number of species has been reported for the USA and these 177 species are 75.6% of the 234 species. Many of the species found in 7 or 8 countries may be present in the other 1or 2 countries, but have not been reported in the literature cited in this book. 3

4     chapter


In this chapter, only the percentages are given for the commodities in each of 28 categories found to be infested by a species. Commodity suitability information from Table 4.1 and Hagstrum and Subramanyam (2009) is included in Table 2.2. The letters s, m or u in parentheses after each commodity indicates whether a commodity is suitable, marginal or unsuitable for insect development, reproduction and/or population growth. In Table 5.1, the sources of the records for each species-commodity combinations are cited. In some cases, facilities that are commonly infested are reported instead of the commodities infested, so a list of facilities is also reported. Under the life history heading, references to studies on insect developmental times over a range of temperatures have been included. The relation between life history and environment are important because these determine the rate of population growth. Some of the variation in developmental times is a result of some individuals going through additional instars (Esperk et al. 2007). Many of these studies include immature mortality. Some studies also consider the effects of commodity moisture content and equilibrium humidity. References to additional

life history studies on the effect of diet can be found in Chapter 4. Most of the life history studies were done in the laboratory. However, some studies report data collected in the field (Bruchus pisorum, Callosobruchus maculatus, Hypothenemus hampei). Fewer studies are available on adult longevity and egg production. Diapause allows pests to evade pest management and survive during periods when commodity is not stored in a facility. Bell (1994) provides a list of stored-product insect species that diapause. For a few species, the literature on their life histories has been reviewed, i. e., Corcyra cephalonica (Hodges 1979), Ephestia elutella (Ashworth 1993a), Hypothenemus hampei (Damon 2000), Lasio­ derma serricorne (Ashwoth 1993b), Nacerdes melanura (Pitman et al. 2003), Plodia interpunctella (Mohandass et al. 2007), Prostephanus truncatus (Nansen and Meikle 2002), Rhyzopertha dominica (Edde 2012) and Sitophilus spp. (Longstaff 1981). Life history data are available for only 40% of the 235 stored product insect species considered in this book. The lists of recorded species of natural enemies are from Hagstrum and Subramanyam (2009) and additional information can be found there.
