Phylogeny Of Family Limnephilidae (Insecta: Trichoptera) With Emphasis On Tribe Limnephilini (Subfamily Limnephilinae), Tatyana Vshivkova

All Dissertations

Morphological characters of adults and immature stages of Limnephilidae were analyzed with modern phylogenetic techniques, including traditionally used characters and some that have been poorly investigated or never studied. For the first time, monophyly is inferred for the following nominotypical taxa: superfamily Limnephiloidea, family Limnephilidae, subfamily Limnephilinae, tribe Limnephilini, and Limnephilus sensu stricto. Some other higher taxa are distinguished based on high bootstrap support, unreversed synapomorphies, and/or topography, including a new family-group category for Trichoptera, 'Branch,' more inclusive than the family category and less inclusive than the superfamily category. These new taxa in Limnephiloidea are as follows: Brachycentrida New Branch …

High-Level Resistance To Bacillus Thuringiensis Toxin Cry1ac And Cadherin Genotype In Pink Bollworm, Aaron J. Gassmann, Robert W. Biggs, Jeffrey A. Fabrick, Bruce E. Tabashnick, Timothy J. Dennehy, Yves Carriere, Shai Morin

Aaron J. Gassmann

Resistance to transgenic cotton, Gossypium hirsutum L., producing Bacillus thuringiensis (Bt) toxin Cry1Ac is linked with three recessive alleles of a cadherin gene in laboratory-selected strains of pink bollworm, Pectinophora gossypiella (Saunders), a major cotton pest. Here, we analyzed a strain (MOV97-R) with a high frequency of cadherin resistance alleles, a high frequency of resistance to 10 μg of Cry1Ac per milliliter of diet, and an intermediate frequency of resistance to 1,000 μg of Cry1Ac per ml of diet. We selected two strains for increased resistance by exposing larvae from MOV97-R to diet with 1,000 μg of Cry1Ac per ml …

Department of Entomology: Faculty Publications

The sex pheromone of the scarab beetle, Phyllophaga anxia, is a blend of the methyl esters of two amino acids, L-valine and L-isoleucine. A field trapping study was conducted, deploying different blends of the two compounds at 59 locations in the United States and Canada. More than 57,000 males of 61 Phyllophaga species (Coleoptera: Scarabaeidae: Melolonthinae) were captured and identified. Three major findings included: (1) widespread use of the two compounds [of the 147 Phyllophaga (sensu stricto) species found in the United States and Canada, males of nearly 40% were captured]; (2) in most species intraspecific male …

An Overview Of The Classification And Evolution Of The Major Scarab Beetle Clades (Coleoptera: Scarabaeoidea) Based On Preliminary Molecular Analyses, Andrew B. T. Smith, David C. Hawks, John M. Heraty

University of Nebraska State Museum: Entomology Papers

We present a preliminary overview of our molecular phylogenetics research on the superfamily Scarabaeoidea. The molecular data consists of 28S ribosomal DNA sequences (mainly D2 and D3 expansion regions) for over 600 taxa and 18S ribosomal DNA sequences (mainly E17 to E35 expansion regions) for over 150 representative taxa within the lineages sampled. Based on our preliminary molecular phylogenetic results, Scarabaeoidea includes three major groups: 1) Geotrupidae, Passalidae, and Pleocomidae; 2) Lucanidae, Diphyllostomatidae, Trogidae, and Glaresidae; and 3) Hybosoridae, Ochodaeidae, Glaphyridae, and Scarabaeidae. The broad evolutionary patterns within the Scarabaeoidea are discussed with respect to phylogeny and evolution.

A Review Of The Family-Group Names For The Superfamily Scarabaeoidea (Coleoptera) With Corrections To Nomenclature And A Current Classification, Andrew B. T. Smith

University of Nebraska State Museum: Entomology Papers

For the first time, all family-group names in the superfamily Scarabaeoidea (Coleoptera) are evaluated using the International Code of Zoological Nomenclature to determine their availability and validity. A total of 383 family-group names were found to be available, and all are reviewed to scrutinize the correct spelling, author, date, nomenclatural availability and validity, and current classification status. Numerous corrections are given to various errors that are commonly perpetuated in the literature. A reversal of precedence is used to preserve the prevailing usage of the following family-group names: Eupariini Schmidt, 1910 (over Ataeniini Harold, 1868); Pachydemini Burmeister, 1855 (over Elaphocerini Blanchard, …

Laboratory Environment Effects On The Reproduction And Mortality Of Adult Screwworm (Diptera: Calliphoridae), Dennis Berkebile, Agustin Sagel, Steven R. Skoda, John E. Foster

Department of Entomology: Faculty Publications

The New World screwworm, Cochliomyia hominivorax Coquerel, is mass reared for screwworm eradication initiatives that use the sterile insect technique. New methods for rearing have helped to reduce the cost of the eradication program. We examined the effect and interaction of three temperatures (24.5, 29.5 and 34.5ºC), two diets (2% spray-dried blood plus 0.05% vitamins and corn syrup carrageenan) and three population densities (300, 400, and 500 flies/cage) on egg production, egg hatch, number of observable fertilized eggs, mortality (male and female) and ovarian development. The three population densities did not affect any of the parameters monitored. Using the protein …

Scarab Beetles In Human Culture, Brett C. Ratcliffe

University of Nebraska State Museum: Entomology Papers

The use of scarab beetles (Coleoptera: Scarabaeidae) by primarily pre- and non-industrial peoples throughout the world is reviewed. These uses consist of (1) religion and folklore, (2) folk medicine, (3) food, and (4) regalia and body ornamentation. The use of scarabs in religion or cosmology, once widespread in ancient Egypt, exists only rarely today in other cultures. Scarabs have a minor role in folk medicine today although they may have been more important in the past. The predominant utilization of these beetles today, and probably in the past as well, is as food with emphasis on the larval stage. Lastly, …

Pb1764-Managing Pests In Childcare Facilities, The University Of Tennessee Agricultural Extension Service

Insects, Pests, Plant Diseases and Weeds

Everyone agrees it is important to protect children and childcare workers from needless contact with products used to manage pests. It is equally as important to make sure children and workers are not harmed or made sick by coming in contact with pests. For example, many people do not know that cockroaches can make people sick. German cockroaches are the most common pests in kitchens. They, along with flies and other pests, can spread germs that can cause food poisoning. Cockroaches can even cause someone with asthma to have an attack. Mosquitoes, ticks, rodents and birds can transfer organisms that …

Comparative Sensitivity Of Freshwater Algae To Atrazine, C. K. Lockert, Kyle D. Hoagland, Blair D. Siegfried

Department of Entomology: Faculty Publications

Widespread use of environmentally persistent herbicides has led to increasing concern over their impact on aquatic ecosystems and nontarget organisms. The triazine herbicide atrazine (6-chloro-N-ethyl-N ¹1-[1-methylethyl]-1,3,5-triazine-2,4- diamine) remains one of the most heavily used pesticides worldwide, and was the second most commonly used conventional pesticide in the U.S. agricultural market in 2001. Atrazine is an S-triazine herbicide that targets the photosynthetic process to control broadleaf weeds. Due to the moderate solubility (33 mg/L at 22°C) and relative persistence of atrazine in water (Solomon et al. 1996), contamination of surface waters as a result of non-point source …

Acute Contact Toxicity Of Oxalic Acid To Varroa Destructor (Acari: Varroidae) And Their Apis Mellifera (Hymenoptera: Apidae) Hosts In Laboratory Bioassays, Nicholas P. Aliano, Marion D. Ellis, Blair D. Siegfried

Department of Entomology: Faculty Publications

Laboratory bioassays were performed to characterize the acute contact toxicity of oxalic acid (OA) to Varroa destructor (Anderson & Trueman) and their honey bee hosts (Apis mellifera L.). Specifically, glass-vial residual bioassays were conducted to determine the lethal concentration of OA for V. destructor, and topical applications of OA in acetone were conducted to determine the lethal dose for honey bees. The results indicate that OA has a low acute toxicity to honey bees and a high acute toxicity to mites. The toxicity data will help guide scientists in delivering optimum dosages of OA to the parasite and …

Prevalence And Association Of The Laboulbenialean Fungus Hesperomyces Virescens (Laboulbeniales: Laboulbeniaceae) On Coccinellid Hosts (Coleoptera: Coccinellidae) In Kentucky, Usa, James D. Harwood, Carlo Ricci, Roberto Romani, Kevin M. Pitz, Alex Weir, John J. Obrycki

Entomology Faculty Publications

The laboulbenialean fungi occur throughout the world and are closely associated with a range of arthropods, including many coleopteran hosts. Throughout the summer of 2004, coccinellids were collected from a Bluegrass savanna woodland ecosystem, dominated by blue ash Fraxinus quadrangulata and Chinkapin Oak Quercus muehlenbergii, and the adults were examined for the presence of Hesperomyces virescens using binocular and scanning electron microscopy. Over 80% of adult Harmonia axyridis, a species previously reported as having a persistent association with the fungus, were infected. No significant differences were observed in incidence on male and female hosts, however, the distribution of …

Pb726-Common Ticks Of Tennessee And Their Control, The University Of Tennessee Agricultural Extension Service

Insects, Pests, Plant Diseases and Weeds

Ticks are external parasites of mammals, birds and reptiles and feed only on the blood of their hosts. They can be distinguished from insects and spiders because the head, thorax and abdomen are fused into a single, sac-like body region. They have four pairs of jointed legs and no antennae. Ticks are found walking on or attached to their hosts or in areas frequented by their hosts. These areas include woodlands, weedy or brushy areas, lawns, dag kennels an dog runs. Ticks frequently wait for a host on vegetation along trails and paths traveled by people or animals.

Insects, Pests, Plant Diseases and Weeds

Ever wondered about those big, black ants in your house? You know, the ants you spray every time you see them in the kitchen and bathroom — but they keep coming back. Or, maybe it took the occurrence of a mating flight of the winged forms (usually in the spring or summer) to alert you to their presence, since the worker ants (no wings) are most active at dusk or in the evening. This publication will help you deal with this challenging pest problem.

Pb1596-Chemical And Nonchemical Management Of Fleas, The University Of Tennessee Agricultural Extension Service

Insects, Pests, Plant Diseases and Weeds

The cat flea, Ctenocephalides felis (Figure 1), is the most common flea found on cats and dogs in Tennessee. These fleas are about 1/16 inch long and are reddish-brown in color. Fleas have bodies flattened from the sides with backward projecting spines so they can easily walk through animal hair. Parts of the legs are enlarged for jumping, which allows an adult flea to jump almost 200 times its height.

Most of us are well aware of the flea and the itch produced by its bite. Not only are flea bites irritating, but fleas can also transmit several disease-causing organisms …

Sp341-S-Head Lice, The University Of Tennessee Agricultural Extension Service

Insects, Pests, Plant Diseases and Weeds

In the United States, approximately 10 – 12 million people, mostly children, are infested annually with head lice, Pediculus humanus capitis DeGeer. The first indication of an infestation is the itching and scratching caused by these bloodsucking insects. Examination of the hair and scalp will usually reveal the white or grayish crawling forms (about the size of a sesame seed) and yellowish- white eggs (nits) attached to the hair shafts close to the scalp.

Lice are usually transferred by the sharing of combs, brushes, hats or bedding, or resting one’s head on upholstered furniture or pillows recently used by an …

The Beetle Fauna Of Dominica, Lesser Antilles (Insecta: Coleoptera): Diversity And Distribution, Stewart B. Peck

Insecta Mundi

The beetle fauna of the island of Dominica is summarized. It is presently known to contain 269 genera, and 361 species (in 42 families), of which 347 are named at a species level. Of these, 62 species are endemic to the island. The other naturally occurring species number 262, and another 23 species are of such wide distribution that they have probably been accidentally introduced and distributed, at least in part, by human activities. Undoubtedly, the actual numbers of species on Dominica are many times higher than now reported. This highlights the poor level of knowledge of the beetles of …
