Home Garden, Lawn, and Landscape

The flatheaded appletree borer, Chrysobothris femorata (Olivier) (FHATB) is a well-documented, native pest of deciduous trees. It has a wide host range and is particularly problematic in commercial nurseries and urban landscapes, where it can cause rapid decline of economically important hosts. When infestations are high, FHATB has been known to attack healthy trees as well as those stressed by drought, plant disease, mechanical injury and other environmental factors. Its distribution is ubiquitous, covering the entire continental United States and extending into Canada.

The bagworm, Thyridopteryx ephemeraeformis (Haworth), is one of the more curious and interesting insect pests of trees and shrubs. Its carrot-shaped bag is constructed of bits of material from the plant upon which it is feeding and is enlarged as the bagworm grows. The bag is carried wherever the worm goes. When disturbed, the bagworm merely pulls its head back into the bag for protection.

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 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 …

Pb595-You Can Control Garden Insects, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

Insect infestations reduce yields and lower the quality of harvested garden vegetables. Three to seven generations of many insect pests attack garden vegetables during the growing season. All plant parts may be injured by insects. Some insects bore into roots, seeds or stems. Many suck large quantities of plant sap. Others destroy crops by chewing on the succulent foliage, stems or fruits. Plant diseases are carried by certain insects.

Safe, effective and economical control measures can minimize the loss from insects. Control can be maintained all season by a combination of cultural practices, mechanical control, biological control and chemical applications. …

Pb1622-Disease And Insect Control In Home Fruit Plantings, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

Growing fruit in the home garden can be an interesting, fun and rewarding hobby. Many novices dream of plucking perfect fruit off trees in their yards.

Sp341-H-Boxelder Bugs And Red-Shouldered Bugs, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

Boxelder bugs, Boisea trivittata (Say), are a nuisance, especially during the cool autumn months when they cluster in large numbers on the sides of trees, houses and other structures. This pest enters buildings through cracks and openings and spends the winter hibernating behind exterior siding and in attics, soffits, wall voids, window/door casings and similar protected areas. Boxelder bugs may also take refuge in soil and leaf litter next to foundations. With the onset of warmer weather in late winter and spring, these bugs become active and emerge from their overwintering sites. As they attempt to escape to their natural …

Pb1215-Disease Control In The Home Vegetable Garden, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

Control of vegetable pests (diseases, insects, weeds) involves a total production program that includes both chemical and non-chemical means of pest control. The establishment of a healthy, vigorous crop is central to a successful pest control program. Production practices such as maintaining proper soil pH and fertility are helpful in reducing potential losses from all types of pests.

This publication deals mainly with chemical and biological pest control, because these recommendations change more often than do cultural practices. Cultural practices of pest control are extremely important and are addressed throughout the publication.
