Some Like It Hot: The Influence And Implications Of Climate Change On Coffee Berry Borer (Hypothenemus Hampei) And Coffee Production In East Africa, Juliana Jaramillo, Eric Muchugu, Fernando E. Vega, Aaron Davis, Christian Borgemeister, Adenirin Chabi-Olaye

All Peer-Reviewed Publications

The negative effects of climate change are already evident for many of the 25 million coffee farmers across the tropics and the 90 billion dollar (US) coffee industry. The coffee berry borer (Hypothenemus hampei), the most important pest of coffee worldwide, has already benefited from the temperature rise in East Africa: increased damage to coffee crops and expansion in its distribution range have been reported. In order to anticipate threats and prioritize management actions for H. hampei we present here, maps on future distributions of H. hampei in coffee producing areas of East Africa. Using the CLIMEX model we relate …

Three New Species Of Goera Stephens (Trichoptera: Goeridae) From Sulawesi, Indonesia, Brian J. Armitage, Tatiana I. Arefina-Armitage

Insecta Mundi

Three new species of the caddisfly genus Goera Stephens (Trichoptera: Goeridae) are described from the Indonesian island of Sulawesi. Goera neboissi sp. n., G. jolanda sp. n., and G. higleri sp. n. were found to be related to G. skiasma Neboiss, which is the only previously recorded species from Sulawesi. These species share the following combination of characters: an upright IXth segment; the absence of the median dorsal process of tergum X; a long, mesal process of the inferior appendage with a subbasal projection; and, the absence of parameres.

Taxonomy, Identification, And Phylogeny Of The African And Madagascan Species Of The Tiger Beetle Genus Chaetodera Jeannel 1946 (Coleoptera: Cicindelidae), Jonathan R. Mawdsley

Insecta Mundi

The taxonomy of the African and Madagascan species of the tiger beetle genus Chaetodera Jeannel 1946 (Coleoptera: Cicindelidae) is reviewed based on studies of primary types and additional museum specimens.

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 …

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 …

Vegetation And The Importance Of Insecticide-Treated Target Siting For Control Of Glossina Fuscipes Fuscipes, Johan Esterhuizen, Basilio Njiru, Glyn A. Vale, Michael J. Lehane, Stephen J. Torr

All Peer-Reviewed Publications

Control of tsetse flies using insecticide-treated targets is often hampered by vegetation re-growth and encroachment which obscures a target and renders it less effective. Potentially this is of particular concern for the newly developed small targets (0.25 high × 0.5 m wide) which show promise for cost-efficient control of Palpalis group tsetse flies. Consequently the performance of a small target was investigated for Glossina fuscipes fuscipes in Kenya, when the target was obscured following the placement of vegetation to simulate various degrees of natural bush encroachment. Catches decreased significantly only when the target was obscured by more than 80%. Even …

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 …

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 …

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.

Elm Bark Beetles And Dutch Elm Disease, Ryan S. Davis

All Current Publications

Bark beetles (Family Curculionidae, Subfamily Scolytinae) are some of the most devastating insect pests in the world. Closely related to weevils, there are almost 500 species of bark beetles in North America alone, each with unique host plants, habits, and life cycles. It is crucial to accurately identify a suspect bark beetle before you consider treatment options.

The fall webworm, Hyphantria cunea, is a common defoliator of ornamental and fruit trees in Utah. Starting around late July, the caterpillars, webbing, and damage become noticeable, particularly in some of the canyons adjacent to populated areas (Little Cottonwood canyon, Logan canyon, Provo canyon, etc.).

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

All Current Publications

The pear sawfly, which is actually a wasp, is a common pest on pear, cherry, and hawthorn in Utah. The slug-like appearance of the larval stage has prompted this insect to also be referred to as the pear or cherry slug in various parts of the country.

The 2007 Rift Valley Fever Outbreak In Sudan, Osama Ahmed Hassan, Clas Ahlm, Rosemary Sang, Magnus Evander

All Peer-Reviewed Publications

Rift Valley fever (RVF) is a neglected, emerging, mosquito-borne disease with severe negative impact on human and animal health and economy. RVF is caused by RVF virus (RVFV) affecting humans and a wide range of animals. The virus is transmitted through bites from mosquitoes and exposure to viremic blood, body fluids, or tissues of infected animals. During 2007 a large RVF outbreak occurred in Sudan with a total of 747 confirmed human cases including 230 deaths (case fatality 30.8%); although it has been estimated 75,000 were infected. It was most severe in White Nile, El Gezira, and Sennar states near …

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 …
