Identifying Avian Malaria Vectors: Sampling Methods Influence Outcomes, Jenny S. Carlson, Erika Walther, Rebecca Trout Fryxell, Sarah Staley, Lisa A. Tell, Ravinder N.M. Sehgal, Christopher M. Barker, Anthony J. Cornel

Entomology & Plant Pathology Publications and Other Works

Background

The role of vectors in the transmission of avian malaria parasites is currently understudied. Many studies that investigate parasite-vector relationships use limited trapping techniques and/or identify potential competent vectors in the field in such ways that cannot distinguish between an infected or infectious vector. Without the use of multiple trapping techniques that address the specific biology of diverse mosquito species, and without looking at the infection status of individual mosquitoes, it is not possible to make dependable conclusions on the role of mosquitoes in the transmission of avian malaria parasites.

Methods

We conducted two years of mosquito collections at …

Plant Sciences Publications and Other Works

Following compilation of distribution records and seasonal flight activity information for 106 metallic wood-boring beetle (Coleoptera: Buprestidae) species for Tennessee, maps were updated to provide county-level collection notations for 10,543 published records and specimen collections made from 1934 to 2013. County collection tallies across the ecoregions in Tennessee are also presented. Maps for individual species highlight gaps in key geographic areas where specimens have not been collected and can be valuable for future biosurveillance, monitoring and management efforts for these economically and ecologically important insects.

Reduced Levels Of Membrane-Bound Alkaline Phosphatase Are Common To Lepidopteran Strains Resistant To Cry Toxins In Bacillus Thuringiensis, Juan Luis Jurat-Fuentes, Lohitash Karumbaiah, Sova Rama Krishna Jakka, Changming Ning, Chenxi Liu, Kongming Wu, Jerreme Jackson, Fred Gould, Carlos Blanco, Maribel Portilla, Omaththage Perera, Michael Adang

Entomology & Plant Pathology Publications and Other Works

Development of insect resistance is one of the main concerns with the use of transgenic crops expressing Cry toxins from the bacterium Bacillus thuringiensis. Identification of biomarkers would assist in the development of sensitive DNA-based methods to monitor evolution of resistance to Bt toxins in natural populations. We report on the proteomic and genomic detection of reduced levels of midgut membrane-bound alkaline phosphatase (mALP) as a common feature in strains of Cry-resistant Heliothis virescens, Helicoverpa armigera and Spodoptera frugiperda when compared to susceptible larvae. Reduced levels of H. virescens mALP protein (HvmALP) were detected by two dimensional differential …

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

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

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 …

Sp547 Common Tree Borers In Tennessee, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

Many types of insect and mite pests can attack trees in home landscapes. Although feeding damage from most of these pests is aesthetically displeasing, it does not cause severe damage to the tree. Even after total defoliation by caterpillars, most trees will put out a new flush of foliage. Several consecutive years or more of defoliation are needed to cause a serious decline or death of most trees. Also, defoliation late in the growing season is much less detrimental to tree health than that occurring in spring or early summer.

Conversely, some pests can routinely cause significant damage and even …

Sp482 The Southern Pine Beetle, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

The Southern Pine Beetle (SPB) inhabits Tennessee forests, and as forest landowners, we should be prepared to deal with the insect. Each year SPB causes thousands of dollars worth of damage to stands of Southern yellow pines, e.g., Loblolly, shortleaf and Virginia pines. Landowners living near or on their property can reduce losses to SPB by knowing the symptoms of a SPB attack, what to do about it and how to prevent it.

Sp290-U Nantucket Pine Tip Moth, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

The Nantucket pine tip moth, Rhyacionia frustrana (Comstock), is a pest of pines in the Eastern, Central and Southern states. Host trees attacked include Scotch, Austrian, Virginia, red, loblolly and shortleaf pines. Longleaf, slash and eastern white pines are rarely attacked.

During recent years, the Nantucket pine tip moth has become an increasingly destructive and abundant pest because of the increase in acreage of pine plantations and seed orchards. Larvae of this moth kill and deform shoots of infested trees. This damage results in a reduction in height, forking or crooking of main stems and, occasionally, death of the tree. …

Sp290-P White Pine Aphid, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

The white pine aphid, Cinara strobi (Fitch), occurs wher ev er Eastern white pines are grown. This pest uses its needle-like mouthparts to suck sap from twigs and branch es. Severely infested parts of trees turn yellow and drop their needles.

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

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 …
