Preventing Poisoning Of Pets When Using Slug And Snail Baits, Kerry A. Rood, Larry A. Sagers

All Current Publications

Slugs and snails are one of the most common garden pests in the State of Utah. Because they are so widespread and destructive, many different methods are used to keep the pests under control. Baits are frequently applied as a treatment, but using pesticides can create hazard for non-target wildlife and pets.

Controlling Slugs And Snails In Utah, Larry A. Sagers, Kerry A. Rood

All Current Publications

Slugs and snails are rated by many gardeners as the worst garden pests. Considering their competition, this is a dubious honor. These pests are not insects but are mollusks that are more closely related to shellfish, such as mussels and clams.

Natural Selection On Body Size Is Mediated By Multiple Interacting Factors: A Comparison Of Beetle Populations Varying Naturally And Experimentally In Body Size, Angela R. Amarillo-Suárez, R Craig Stillwell, Charles W. Fox

Entomology Faculty Publications

Body size varies considerably among species and among populations within species, exhibiting many repeatable patterns. However, which sources of selection generate geographic patterns, and which components of fitness mediate evolution of body size, are not well understood. For many animals, resource quality and intraspecific competition may mediate selection on body size producing large-scale geographic patterns. In two sequential experiments, we examine how variation in larval competition and resource quality (seed size) affects the fitness consequences of variation in body size in a scramble-competing seed-feeding beetle, Stator limbatus. Specifically, we compared fitness components among three natural populations of S. limbatus …

Life History Of An Exotic Soft Scale Insect Phalacrococcus Howertoni (Hemiptera: Coccidae) Found In Florida, Kaushalya G. Amarasekare, Catharine M. Mannion

Agricultural and Environmental Sciences Faculty Research

We investigated the life history of an exotic soft scale insect, Phalacrococcus howertoni Hodges and Hodgson that damages croton and several other economically important ornamental and fruit plants in Florida. There was no difference in the development, survival, and reproduction of this scale insect species when reared either on croton or on buttonwood at 27 ± 1°C, 12:12 (L:D) h and 65% R. H. The scale insect practiced ovoviviparity. We observed that eggs that came out from vulva hatched to first instars immediately. Newly hatched nymphs had a tendency stay underneath the female body for somewhat less than approximately 24 …

First Transcriptome Of The Testis-Vas Deferens-Male Accessory Gland And Proteome Of The Spermatophore From Dermacentor Variabilis (Acari: Ixodidae), Daniel E. Sonenshine, Brooke W. Bissinger, Noble Egekwu, Kevin V. Donohue, Sayed M. Khalil, R. Michael Roe

Biological Sciences Faculty Publications

Ticks are important vectors of numerous human diseases and animal diseases. Feeding stimulates spermatogenesis, mating and insemination of male factors that trigger female reproduction. The physiology of male reproduction and its regulation of female development are essentially a black box. Several transcriptomes have catalogued expression of tick genes in the salivary glands, synganglion and midgut but no comprehensive investigation has addressed male reproduction and mating. Consequently, a new global approach using transcriptomics, proteomics, and quantitative gene expression is needed to understand male reproduction and stimulation of female reproduction.This first transcriptome to the reproductive biology of fed male ticks, Dermacentor variabilis …

Pear Sawfly, Vincent P. Jones, Ryan S. Davis

Review Of The Species Described In Leptostilbus Casey In North America (Coleoptera: Phalacridae: Xanthocomus Guillebeau), Matthew L. Gimmel

Insecta Mundi

The species of Phalacridae (Coleoptera) historically included in Leptostilbus Casey, 1916, are reviewed. Leptostilbus rutilans Casey, 1916, is here designated as the type species of Leptostilbus. The genus Leptostilbus is synonymized with Xanthocomus Guillebeau, 1893, syn. nov., resulting in two new combinations, Xanthocomus concinnus (Casey, 1916) and X. rutilans (Casey, 1916). Lectotypes are here designated for these two species. Acylomus elongatulus (Casey, 1890), comb. nov., formerly placed in Leptostilbus, is excluded from Xanthocomus. A key and illustrations are provided to aid in recognition of the two species of Xanthocomus in North America, and detailed distribution maps are …

Eriophyid Mites, Bud, Blister, Gall, And Rust Mites, Ryan S. Davis, Taun Beddes

All Current Publications

Eriophyid mites are translucent, cigar-shaped microscopic mites that cause deformities on many plants species. These mites are noticed when their feeding causes abnormalities of plant tissues such as erineum, galls, brooms, leaf curling, blisters, rusts, silvering, fruit rusetting, and deformed buds, catkins, fruits, etc. Fortunately, these mites rarely cause serious harm to plants, and control is seldom needed. In fact, eriophyid mites can serve as an alternative food source for predatory mites when their primary food source is absent.

Male Mating Competitiveness Of A Wolbachia-Introgressed Aedes Polynesiensis Strain Under Semi-Field Conditions, Eric W. Chambers, Limb Hapairai, Bethany A. Peel, Hervé Bossin, Stephen L. Dobson

Entomology Faculty Publications

BACKGROUND: Lymphatic filariasis (LF), a global public health problem affecting approximately 120 million people worldwide, is a leading cause of disability in the developing world including the South Pacific. Despite decades of ongoing mass drug administration (MDA) in the region, some island nations have not yet achieved the threshold levels of microfilaremia established by the World Health Organization for eliminating transmission. Previously, the generation of a novel Aedes polynesiensis strain (CP) infected with an exogenous type of Wolbachia has been described. The CP mosquito is cytoplasmically incompatible (i.e., effectively sterile) when mated with wildtype mosquitoes, and a strategy was proposed …

Ecology And Management Of The Woolly Whitefly (Hemiptera: Aleyrodidae), A New Invasive Citrus Pest In Ethiopia, Difabachew K. Belay, Abebe Zewdu, John E. Foster

Department of Entomology: Faculty Publications

Distribution and importance of woolly whitefly (Aleurothrixus floccosus) (Maskell) (Hemiptera: Aleyrodidae), was studied in Ethiopia with an evaluation of treatments against it. Results showed that the pest is distributed in most citrus-growing parts of the country equally infesting all types of citrus crops. Only one pupal parasitoid, Amitus sp., was recorded at Melkaoba. During 2006–2007, eight treatments gave better control of woolly whitefly compared with the control: endod (Phytolacca dodecandra L’Herit) berry extract, white oil 80%, neem oil, omo detergent soap, band application of gasoline, cyhalothrin (karate) 5% EC, selecron (profenofos) 500 EC, and rimon (novaluron) 10 EC. …

Large-Scale Rnai Screen Of G Protein-Coupled Receptors Involved In Larval Growth, Molting And Metamorphosis In The Red Flour Beetle, Hua Bai, Fang Zhu, Kapil Shah, Subba R. Palli

Entomology Faculty Publications

BACKGROUND: The G protein-coupled receptors (GPCRs) belong to the largest superfamily of integral cell membrane proteins and play crucial roles in physiological processes including behavior, development and reproduction. Because of their broad and diverse roles in cellular signaling, GPCRs are the therapeutic targets for many prescription drugs. However, there is no commercial pesticide targeting insect GPCRs. In this study, we employed functional genomics methods and used the red flour beetle, Tribolium castaneum, as a model system to study the physiological roles of GPCRs during the larval growth, molting and metamorphosis.

RESULTS: A total of 111 non-sensory GPCRs were identified in …

Beneficial True Bugs: Damsel Bugs, Ricardo Ramirez, Ron Patterson

All Current Publications

Predatory insects can provide natural pest control by eating unwanted pests. This beneficial service is known as biological control. Predatory insects are one factor that maintains pest populations at non-damaging levels. By conserving and encouraging predatory insect populations, plants can be protected from pest attack and excessive damage.

European Earwig (Forficula Auricularia), Diane G. Alston, Andrew Tebeau

All Current Publications

The European earwig (Order Dermaptera, which means “skin wings” to describe their leathery wings) (Fig. 1) is native to Europe, western Asia, and parts of Africa. The common name “earwig” comes from a myth that the insect would climb into the ears of humans and chew into the brain, but this is false. The European earwig was first introduced into Utah in the early 1900s. Establishment and population growth have been remarkably successful in northern Utah.
