W221-Mid-South Multi-State Evaluation Of Treatment Thresholds For Tarnished Plant Bug In Pre-Flowering Cotton, The University Of Tennessee Agricultural Extension Service
W221-Mid-South Multi-State Evaluation Of Treatment Thresholds For Tarnished Plant Bug In Pre-Flowering Cotton, The University Of Tennessee Agricultural Extension Service
Field & Commercial Crops
Prior to bloom, the primary hemipteran pest of cotton in the Mid-South is the tarnished plant bug (TPB). Cotton fleahopper and clouded plant bug are other hemipteran pests that are occasionally observed. These pests reduce yields by feeding on squares (flower buds), which often shed. Mid-sized or larger squares may not shed, but feeding injury is generally evident in the form of yellow staining on the surface of the square and damaged anthers in flowers (i.e., dirty blooms). Square loss can delay maturity and sometimes reduce yield. Delays in crop maturity, even when not causing yield loss, can increase mid-and …

Sp290-Z-Commercial Sources Of Predators, Parasitoids & Pathogens, The University Of Tennessee Agricultural Extension Service
Commercial Horticulture
The Agricultural Extension Service receives numerous inquiries for information about where insect predators and parasitoids can be purchased. These insects are intended for use by both homeowners and commercial growers as biological control agents.
Biological control uses beneficial organisms rather than insecticides to reduce insect populations. Almost all insect groups include some benefi cial members. The use of beneficial organisms is particularly important where chemical residues are undesirable. Beneficial organisms can be predators, such as ladybugs, lacewings and praying mantids that feed on other insects. Others, such as some species of nematodes and wasps, including Trichogramma, are parasitoids with …

Sp341-W-Insects In Grain Bins, The University Of Tennessee Agricultural Extension Service
Field & Commercial Crops
One of the most common insects in stored grain is the Indian-meal moth, Plodia interpunctella (Hubner). These moths are called “flour moths” in Tennessee because they feed on flour or milled products. In farm grain bins, they prefer broken grains or grains damaged by other pests and seldom attack sound grain kernels. They cause problems by spinning webbings as immature. This causes lower quality in stored grain.
Sp290-K The Hessian Fly In Wheat, The University Of Tennessee Agricultural Extension Service
Sp290-K The Hessian Fly In Wheat, The University Of Tennessee Agricultural Extension Service
Field & Commercial Crops
The Hessian fly is a pest of winter wheat in Tennessee and other wheat-growing states. This pest caused disastrous losses in Tennessee wheat in the mid- 1980s. Later planting of wheat and the use of wheat varieties resistant to Hessian fly minimized economic losses from this pest. In the coming years, potential economic losses from Hessian fly could increase due to the lack of resistance varieties.
In 2009, very little attention was given to Hessian fly infestations. However, there are some varieties with moderate resistance to biotype L Hessian fly. None are completely resistant. Some of the better methods to …

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.

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.

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.”

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.

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.

Sp290-N The Greenbug In Grain Sorghum, The University Of Tennessee Agricultural Extension
Field & Commercial Crops
Greenbugs are small (1.6 mm long), soft-bodied insects that are oval in shape. Greenbugs usually feed in colonies by sucking sap from leaves. Feeding may cause mottling and discoloration of the plant. Heavily infested leaves turn red or yellow, shrivel and die. Damaging levels of greenbugs can result in the destruction of entire grain sorghum fields.

Sp341-A-Protect Farm-Stored Grain, The University Of Tennessee Agricultural Extension Service
Field & Commercial Crops
Several insect species attack stored grain, resulting in both direct and indirect losses. Direct losses from insect feeding result in reduced grain weight, loss of nutrients and decreased germination. Indirectly, the presence of insects causes a deterioration and contamination of grain. This results in a poorer grade of grain and lower market value.
Sp341-F-Periodical Cicadas, The University Of Tennessee Agricultural Extension Service
Sp341-F-Periodical Cicadas, The University Of Tennessee Agricultural Extension Service
Home Garden, Lawn, and Landscape
The periodical cicada, Magicicada species, has the longest developmental period of any insect in North America. There is probably no insect that attracts as much attention in eastern North America as does the periodical cicada. Their sudden springtime emergence, filling the air with their high-pitched, shrill-sounding songs, excites much curiosity.
Two races of the periodical cicada exist. One race has a life cycle of 13 years and is common in the southeastern United States. The other race has a life cycle of 17 years and is generally more orthern in distribution. Due to Tennessee’s location, both the 13- year and …
