Dermestid Beetle C ontrol • Do not accumulate woolens or articles made of animal by-products unless they are extremely important to you. • Do not keep or store woolens that are not used regularly. • During non-use seasons, store woolen clothing in tightly-sealed containers or "moth-proof" bags. In most cases the inclusion of mothballs is advised. • Since these beetles can develop in stored foods, be especially watchful for infestations that start there…
Lady beetles (Coccinellidae) • Also known as Ladybird beetles. • Adults are rounded, and range in size from tiny to ¼ inch long. Color ranges from black to brightly colored. • Larvae are active and elongate with long legs, and look like tiny alligators. • Adults very mobile; will leave to find pest. • Feed on scales, eggs of larvae and other soft- bodied insects and mites • 5,000 aphids in a lifetime!

Oder Diptera: Flies, Mosquitoes, Gnats, Midges Order Diptera – “two wing” • One pair of wings. - second wing is haltere (gyroscope) • Complete Metamorphosis. • Larvae have chewing mouthparts or mouth hooks. • Adults with sucking mouthparts. • Greater economic impact than any other insect group - Pests and vectors of disease. • Beneficial - pollinate flowering plants. - assist with decomposition of organic matter. - biocontrol agents of insect pests.
Flies
Leaf miners • Tunnel between the upper and lower leaf surface feeding on the soft inner tissues. • Tolerated by plants unless infestations precipitate high levels of leaf damage. • Cosmetic pest. Chrysanthemum leaf miner

Syrphid flies, flower flies, hover flies (Syrphidae)
Predator Syrphid flies, flower flies, hover flies (Syrphidae) • Large group of flies. • 1/4 to 3/4 inch long. • Most adults eat pollen and nectar (good pollinator). • Adults are black and yellow, often hover around flowers, and look like bees (but do not sting). • Larvae feed on aphids, leafhoppers, mealybugs, scale insects, and thrips.
Predator Syrphid flies, flower flies, hover flies (Syrphidae) • Good for slow moving, soft bodied insects. • Early in the growing season. • Single individual can consume up to 400 aphids in a life time.
Order Hymenoptera Wasps, Bees, Ants, Horntails, Sawflies Order Hymenoptera – “membrane wing” • Complete Metamorphosis. • Two pairs of membranous wings. • Chewing mouthparts. • Important pollinators! • Beneficial. • Social.
Ants • Social insects. • Usually live underground. • Some ants will eat soft bodied insects. • Often times considered a nuisance in homes and/or a pest in the garden. Right: Red imported fire ants ( Solenopsis invicta ) with cerambycid larvae.

Hornets, paper wasps (Vespidae Polistes ) Solitary/Hunting Wasps Paper Wasps • Adults eat mainly caterpillars and feed their larvae beetles, flies, true bugs, and other wasps. • Adults switch to feed on sugar in late summer. • Yellow and black markings. • Some are more aggressive than others.

Honey Bees Like to Dance!
Honey Bee “Waggle Dance” Waggle dance is a term used in beekeeping for a particular figure-eight dance of the honey bee.

World Crop Production Of the 100 crops that provide 90 percent of the world's food, over 70 are pollinated by bees. Honey bees account for a third of the $3 trillion worth of agricultural produce sold each year!

Bee – Economics 101 & Supply and Demand “In the next 20 years the cost of Honey Bee pollinated foods could double or triple as bees continue to DIE off.”
What? Could It Be True, No More Honey Bees??? Population In the last 20 years the domesticated honey bee population has shrunk by 30-50% in the U.S.

Varroa destructor – Single Biggest Issue
The biggest killer? Mites & Parasitic Fungus Varroa mites - These tiny parasites from Siberia have now spread around the world. Attack both larvae and adult bees and reduce bees’ resistance to viral infection. Tracheal mites – Introduced in the early 1980s, attack the Varroa mite respiratory system of adult bees causing them to choke and can wipe out a colony in a day. Nosema – A single celled fungal parasite that spread from the Asian honeybee. The bees’ digestive track is destroyed inhibiting the digestion of pollen causing the bees to starve to death. Nosema also affects the Queen’s ability to lay eggs. Tracheal mites In a recent study at Oregon State University of 247 samples from across the state, 137 (55%) of those samples had the Nosema parasite present and 234 (94%) had Varroa mites present. Nosema Infection
Pesticides Using pesticides on plants kills insects - the bad insects as well as the good insects. When the honey bee collects pollen or nectar, they may become contaminated with the pesticide which could be carried back to the hive; thus potentially killing nest mates. Neonicotinds (a class of chemical found in recently developed pesticides) have already been outlawed in France since it damages the bees’ ability to navigate.
Why are Native Bees in Decline? Competition with introduced species (about 28 new species in North America) Climate Change Habitat Loss and Lack of Nutrition
