Pb1768 2010 Insect Control Recommendations For Field Crops –, The University Of Tennessee Agricultural Extension Service
Field & Commercial Crops
An Integrated Pest Management (IPM) program integrates control tactics including cultural practices, variety selection, biological control and insecticides to manage insect pest populations so that economic damage and harmful environmental side effects are minimized. Insecticides should only be used on an as-needed basis; therefore, insect scouting must be conducted regularly throughout the season to determine if an insecticide application is warranted.
Bed Bugs: For Pest Control Operators, Ryan S. Davis
Bed Bugs: For Pest Control Operators, Ryan S. Davis
All Current Publications
Over the past decade reports of bed bug infestations (Cimicidae: Cimex lectularius) throughout North America and abroad have been on the rise. Accordingly, bed bug submissions to the Utah Plant Pest Diagnostic Lab have also been increasing.
The Chemistry Of Lipid Signal Molecules In Insects, Sean M. Putnam
The Chemistry Of Lipid Signal Molecules In Insects, Sean M. Putnam
Department of Entomology: Dissertations, Theses, and Student Research
I report on the chemical identification of lipid signaling molecules in three species of insects and describe the chemical isolation of a bacterial product that inhibits eicosanoid biosynthesis. Chapter 2 reports that eicosanoids mediate nodulation reactions to bacterial infection in newly-emerged, but not forager honeybees. Cyclooxygenase and lipoxygenase inhibitors attenuate nodulation, which is reversed in the presence of arachidonic acid. Older adult honeybees do not produce bacterial-induced nodules, and they have fewer circulating hemocytes, from which I infer that foraging honeybees express a physiological trade-off between maintaining a biologically expensive hemocytic immune system and flight activity associated with foraging.

Pb1395-Insects In Farm-Stored Grain: 2009 Prevention And Control, The University Of Tennessee Agricultural Extension Service
Field & Commercial Crops
Insects damage stored grain in two ways:
1. Direct feeding damage, resulting in loss of weight, loss of nutrients, reduction in germination, reduction in grade and a lowering of market value.
2. Deterioration and contamination by their presence, resulting in downgrading of grain and lowering of market value because of foreign matter in grain (insects and insect parts), odors, molds and heat-damaged grain.

Sp290-E-Azalea Lace Bug, The University Of Tennessee Agricultural Extension Service
Home Garden, Lawn, and Landscape
Since its introduction from Japan in the early 1900s, the azalea lace bug has become a destructive pest of azaleas. Although this bug prefers evergreen azalea varieties, it will infest deciduous varieties. Mountain laurel can also become infested.

W207-Vegetable Pests - Melon Aphid, The University Of Tennessee Agricultural Extension Service
Home Garden, Lawn, and Landscape
The melon aphid, Aphis gossypii Glover, is found throughout most of the temperate, subtropic and tropic regions of the world. Although it is a cosmopolitan species, its origin is unknown. The melon aphid has a wide host range and can feed on watermelon, cucumber, cantaloupe, squash, pumpkin, asparagus, spinach, bean, beet, cowpea, tomato, pepper, eggplant, okra, citrus, cotton, hibiscus and many weeds (such as jimsonweed and pigweed). In the South, cotton is an important host, which explains the use of the second common name, “cotton aphid.”
W208-Vegetable Pests - Colorado Potato Beetle, The University Of Tennessee Agricultural Extension Service
W208-Vegetable Pests - Colorado Potato Beetle, The University Of Tennessee Agricultural Extension Service
Home Garden, Lawn, and Landscape
The Colorado potato beetle, Leptinotarsa decemlineata (Say), is found throughout most of the United States and Mexico and has been introduced into Europe and parts of Asia. Mexico is considered the center of origin for this pest. The Colorado potato beetle is an important pest of Solanaceous plants. Potato is the preferred host, but this insect pest also will feed on tomato, eggplant, pepper, tobacco, ground cherry, horse-nettle, nightshade, belladonna, thorn apple, henbane, buffalobur and other related plant species.

W206-Vegetable Pests - Pickleworm, The University Of Tennessee Agricultural Extension Service
Home Garden, Lawn, and Landscape
The pickleworm, Diaphania nitidalis (Stoll) (Family Crambidae, previously Pyralidae), is found from Canada into parts of South America, and as far west as Oklahoma and Nebraska. It is an important pest of numerous cucurbits. Summer squash is the preferred host, but it also feeds on cantaloupe, cucumber, pumpkin and winter squash. Late-planted cantaloupes are heavily attacked in some areas.
