Host Instar Susceptibility And Selection And Interspecific Competition Of Three Introduced Parasitoids Of The Mealybug Paracoccus Marginatus (Hemiptera: Pseudococcidae), Kaushalya G. Amarasekare, Catharine M. Mannion, Nancy D. Epsky Oct 2010

Host Instar Susceptibility And Selection And Interspecific Competition Of Three Introduced Parasitoids Of The Mealybug Paracoccus Marginatus (Hemiptera: Pseudococcidae), Kaushalya G. Amarasekare, Catharine M. Mannion, Nancy D. Epsky

Agricultural and Environmental Sciences Faculty Research

Three previously introduced parasitoids (Acerophagus papayae Noyes and Schauff, Anagyrus loecki Noyes and Menezes, and Pseudleptomastix mexicana Noyes and Schauff [Hymenoptera: Encyrtidae]) of the mealybug Paracoccus marginatus Williams and Granara de Willink (Hemiptera: Pseudococcidae) were studied for their host instar susceptibility and sex ratio, host instar selection, and interspecific competition in the laboratory. All three parasitoids were able to develop in the second instars, third-instar females, and adult females of P. marginatus. No progeny emerged from first-instar mealybugs. The proportion of female emergence was increased with increasing host size. Parasitoids selected their host instars for oviposition when they …

Sp503-I-Identifying The Flathead Appletree Borer (Chrysobothris Femorata) And Other Buprestid Beetle Species In Tennessee, The University Of Tennessee Agricultural Extension Service Apr 2010

Sp503-I-Identifying The Flathead Appletree Borer (Chrysobothris Femorata) And Other Buprestid Beetle Species In Tennessee, The University Of Tennessee Agricultural Extension Service

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.


Sp341-U-The Bagworm And Its Control, The University Of Tennessee Agricultural Extension Service Apr 2010

Sp341-U-The Bagworm And Its Control, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

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.


Sp290-C-Dogwood Borer, Infestation, Damage And Control, The University Of Tennessee Agricultural Extension Service Apr 2010

Sp290-C-Dogwood Borer, Infestation, Damage And Control, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

The flowering dogwood (Cornus florida) is one of the most popular ornamental plants in Tennessee landscapes. Native trees also flourish in the forest understory.

The dogwood tree is damaged by the feeding activity of the dogwood borer larva under the bark of the trunk and limbs. In a single year, one borer can completely girdle and kill a tree 4 inches in diameter, but death is more often brought about by the combined activity of several larvae or by successive infestations with concurrent mechanical injury or pathological problems. Cultivated trees growing in full sun are usually more heavily infested than …

Sp290-M Maple Petiole Borer, The University Of Tennessee Agricultural Extension Service Apr 2010

Sp290-M Maple Petiole Borer, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

The maple petiole borer, Caulocampus acericaulis (MacGillivray), was first introduced into the United States from Europe. This sawfly is wasp-like in appearance and is rarely seen because of its small size. Although several species of maple are subject to attack by this insect, sugar maples are preferred.

Sp341-Q Sugarcane Beetle In Field Corn, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

The sugarcane beetle is an occasional pest of field corn in Tennessee. Infestations have been spotty to date and not too damaging in terms of stand and yield losses. However, the beetle caused serious damage in corn during the 2001 and 2002 growing seasons. The fields affected were corn planted into pasture, sod or no-till and some conventional tillage corn.


W221-Mid-South Multi-State Evaluation Of Treatment Thresholds For Tarnished Plant Bug In Pre-Flowering Cotton, The University Of Tennessee Agricultural Extension Service Apr 2010

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 …
