Schools Integrated Pest Management (Ipm) for Wasps and Bees
SCHOOLS INTEGRATED PEST MANAGEMENT (IPM) FOR WASPS AND BEES *Important Note* According to the Virginia Pesticide Control Act (Section 3.1-249.53), in order to apply ANY pesticide (including Raid, Round-Up, and other over-the-counter pesticides) in public areas of ANY educational institution, the applicator must first be certified by the Virginia Department of Agriculture and Consumer Services. In other words, it is illegal for uncertified teachers, staff, administrators, or contractors to apply pesticides on school grounds. INTRODUCTION Bees and wasps experience “complete metamorphosis”. This means that they pass Wasps and bees are both beneficial and through four different life stages: egg, larva, problematic. Wasps, being predators, play pupa, and adult (see Figure 1).

It can also cause damage to poultry housing and is suspected to be a health risk to humans in close contact with larvae and adults. Adults can become a nuisance when they move en masse toward artificial lights generated by residences near fields where beetle-infested manure has been spread (Axtell 1999). Alphitobius diaperinus inhabits poultry droppings and litter and is considered a significant pest in the poultry industry. Numerous studies have been conducted on lesser meal- worm biology, physiology, and management. Lambkin (2001) conducted a thorough review of relevant scientific literature in reference to A. diaperinus and provides a good understanding of the biology, ecology and bionomics of the pest. Bruvo et al. (1995) conducted molecular work to determine satellite DNA variants on the chromosomes of A. diaperinus. Alphitobius diaperinus is a member of the tenebrionid tribe Alphitobiini (Doyen 1989), which comprises four genera worldwide (Aalbu et al. 2002). Two genera occur Figure 1.

Eating insects is also interesting in terms of low greenhouse gas emissions and low land use. In contrast to tropical countries, where most of the 2000 edible insect species are traditionally consumed, the concept of eating insects is still new to Western culture and diet. Culture and eating habits exert a great influence on what is considered edible in the Mediterranean area, especially in Italy, where the preservation of culinary traditions is a predominant factor affecting dietary behaviour. The purpose of this narrative paper is to provide an overview of the main topics related to entomophagy. -

Darkling Beetles and Mealworms Theresa A
Darkling Beetles and Mealworms Theresa A. Dellinger and Eric R. Day, Department of Entomology, Virginia Tech Description Darkling beetles belong in the beetle family Tenebrionidae, which consists of more than 20,000 species of beetles. Adult darkling beetles widely range in shape and size, with most measuring from 2 – 19 mm (0.13” – 0.75”). Adults are usually a reddish-brown to brownish-black in color and can be shiny or dull. The elytra (the wing covers) can be smooth, grooved, or otherwise sculptured. Most do not have colorful patterns on their wing covers. Adults are most active at night and tend to avoid bright lights. Darkling beetle larvae are often referred to as mealworms or false wireworms. They are long, hard-bodied grubs with a cylindrical shape and are shiny yellow-brown to darKer brown in color. They are active crawlers. Yellow mealworm larva, top. Dark mealworm larva, bottom. Clemson University-USDA Cooperative Adult yellow mealworm, Tenebrio molitor. Extension Slide Series, Bugwood.org. Clemson University-USDA Cooperative Extension Slide Series, Bugwood.org. Life Cycle Darkling beetles have a complete life cycle with egg, larval, pupal, and adult stages. Most species of darkling beetles have a slow rate of development and may live for a year as an adult. Species living on grains or other stored products may develop faster. Habitat/Distribution Darkling beetles are found throughout the world except for places with very cold climates. They are scavengers and omnivores, feeding on decomposing plant material, dead insects, fungi, and stored products. Only a handful of darkling beetles are considered pests; the vast majority of them live in the wild and pose no harm. -
Vegetarianism and World Peace and Justice

We find ourselves in a world of conflict and war. Why do people fight? Some conflict is driven by a desire to impose a value system, some by intolerance, and some by pure greed and quest for power. The struggle to obtain resources to support life is another important source of conflict; all creatures have a drive to live and sustain themselves. In 1980, Richard J. Barnet, director of the Institute for Policy Studies, warned that by the end of the 20th century, anger and despair of hungry people could lead to terrorist acts and economic class war [Staten Island Advance, Susan Fogy, July 14, 1980, p.1]. Developed nations are the largest polluters in the world; according to Mother Jones (March/April 1997, http://www. motherjones.com/mother_jones/MA97/hawken2.html), for example, Americans, “have the largest material requirements in the world ... each directly or indirectly [using] an average of 125 pounds of material every day ... Americans waste more than 1 million pounds per person per year ... less than 5 percent of the total waste ... gets recycled”. In the US, we make up 6% of the world's population, but consume 30% of its resources [http://www.enough.org.uk/enough02.htm]. Relatively affluent countries are 15% of the world’s population, but consume 73% of the world’s output, while 78% of the world, in developing nations, consume 16% of the output [The New Field Guide to the U. -

It would appear to be a strategic alternative in the future of human diet to face the challenge of ensuring food security for a growing world population, using more environmentally sustainable production systems than those required for the rearing of other animals. Tenebrio molitor, called yellow mealworm, is one of the most interesting insect species in view of mass rearing, and can be processed into a powder that ensures a long shelf life for its use in many potential products. -
Insects for Human Consumption
Chapter 18 Insects for Human Consumption Marianne Shockley1 and Aaron T. Dossey2 1Department of Entomology, University of Georgia, Athens, GA, USA, 2All Things Bugs, Gainesville, FL, USA 18.1. INTRODUCTION The utilization of insects as a sustainable and secure source of animal-based food for the human diet has continued to increase in popularity in recent years (Ash et al., 2010; Crabbe, 2012; Dossey, 2013; Dzamba, 2010; FAO, 2008; Gahukar, 2011; Katayama et al., 2008; Nonaka, 2009; Premalatha et al., 2011; Ramos- Elorduy, 2009; Smith, 2012; Srivastava et al., 2009; van Huis, 2013; van Huis et al., 2013; Vantomme et al., 2012; Vogel, 2010; Yen, 2009a, b). Throughout the world, a large portion of the human population consumes insects as a regular part of their diet (Fig. 18.1). Thousands of edible species have been identified (Bukkens, 1997; Bukkens and Paoletti, 2005; DeFoliart, 1999; Ramos-Elorduy, 2009). However, in regions of the world where Western cultures dominate, such as North America and Europe, and in developing countries heavily influenced by Western culture, mass media have negatively influenced the public’s percep- tion of insects by creating or reinforcing fears and phobias (Kellert, 1993; Looy and Wood, 2006). Nonetheless, the potentially substantial benefits of farming and utilizing insects as a primary dietary component, particularly to supplement or replace foods and food ingredients made from vertebrate livestock, are gain- ing increased attention even in Europe and the United States. Thus, we present this chapter to -

Preventing Pests and Pathogens in Honey Bee Colonies
BestBest ManagementManagement PracticesPractices toto PreventPrevent thethe SpreadSpread ofof PestsPests andand PathogensPathogens inin HoneybeeHoneybee ColoniesColonies Photos by Rob Snyder (used with permission) Many pest and disease problems in managed honeybee hives can be avoided by practic- ing good sanitation and cultural controls. Prevention is the first and best line of defense against organisms that can harm your colonies. Sanitation Tools should be sterilized with flame and scrubbed with isopropyl alcohol after working in or inspecting a hive. Avoid using other beekeeper’s tools that have not been properly cleaned. Clothing and gloves that are exposed to a hive where disease is suspected needs to be scrubbed and disinfected with 10% bleach solution or disposed. If not using gloves, rinse hands with rubbing alcohol then scrub with soap and water after working in a hive that appears to have been infected with disease. When disease is suspected, practice the previously mentioned steps between working hive to hive in the same beeyard. Cultural Controls When purchasing a bee colony, find out if the seller has been treating with antibiotics for patho- gens. Treated colonies could already be infected with disease, even in the absence of symptoms. Never switch frames from a box that is suspected to have pests and pathogens to a box without such problems. Do not purchase or accept used frames, boxes, or other beekeeping equipment that have not been inspected and certified by your county’s bee inspector. Boxes infected with American Foulbrood should be marked with the letters “AFB” followed by the year to prevent unintentional contamination. Equipment that has been infected with American Foulbrood must be treated or burned and buried. -
PESTS of STORED PRODUCTS a 'Pest of Stored Products' Can Refer To
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. Technically, these pests can include microorganisms such as fungi and bacteria, arthropods such as insects and mites, and vertebrates such as rodents and birds. Stored product pests are responsible for the loss of millions of dollars every year in contaminated products, as well as destruction of important documents and heritage artifacts in homes, offices and museums. Many of these pests are brought indoors in items that were infested when purchased. Others originate indoors when susceptible items are stored under poor storage conditions, or when stray individual pests gain access to them. Storage pests often go unnoticed because they infest items that are not regularly used and they may be very small in size. Infestations are noticed when the pests emerge from storage, to disperse or sometimes as a result of crowding or after having exhausted a particular food source, and search for new sources of food and harborage. Unexplained occurrences of minute moths and beetles flying in large numbers near stored items, or crawling over countertops, walls and ceilings, powdery residues below and surrounding stored items, and stale odors in pantries and closets can all indicate a possible storage pest infestation. Infestations in stored whole grains or beans can also be detected when these are soaked in water, and hollowed out seeds rise to the surface, along with the adult stages of the pests, and other debris.
