Bumble Flower Beetle, Taun Beddes, Ryan S. Davis

All Current Publications

The bumble flower beetle (BFB) is a common member of the Scarabaeidae (scarab) beetle family. Its common name originated because adult BFB’s often fly close to the ground and emit a loud buzzing sound similar to that of a bumble bee. Larvae (grubs) and adults are often found in or near fermenting and/or decomposing organic matter.

Corn Earworm, Diane G. Alston, Shawn Olsen, James Barnhill

All Current Publications

In Utah, there are typically three generations of corn earworm (CEW) each year. The first generation of adults either come from overwintering pupae (southern and central Utah), or migrate into northern Utah. The adult moth is tannish brown with a 1 1/2 inch wingspan. The front wings are marked with a distinct dark spot in the center and darker bands near the outer margins. The hind wings are lighter tan, with a dark band along the outer margins. The male moths have green eyes. Moth flight occurs primarily on warm, overcast evenings. Moth populations can be monitored using pheromone or …

Wolbachia Infections That Reduce Immature Insect Survival: Predicted Impacts On Population Replacement, Philip R. Crain, James W. Mains, Eunho Suh, Yunxin Huang, Philip H. Crowley, Stephen L. Dobson

Entomology Faculty Publications

BACKGROUND: The evolutionary success of Wolbachia bacteria, infections of which are widespread in invertebrates, is largely attributed to an ability to manipulate host reproduction without imposing substantial fitness costs. Here, we describe a stage-structured model with deterministic immature lifestages and a stochastic adult female lifestage. Simulations were conducted to better understand Wolbachia invasions into uninfected host populations. The model includes conventional Wolbachia parameters (the level of cytoplasmic incompatibility, maternal inheritance, the relative fecundity of infected females, and the initial Wolbachia infection frequency) and a new parameter termed relative larval viability (RLV), which is the survival of infected larvae relative to …

Establishing Lower Developmental Thresholds For A Common Blowfly: For Use In Estimating Elapsed Time Since Death Using Entomologyical Methods, Gail S. Anderson, Jodie-A. Warren

Faculty Research, Scholarly, and Creative Activity

Forensic entomology is a science used to estimate a post-mortem interval (PMI). Larvae develop at predictable rates and the time interval for this development can be used to estimate the PMI. Environmental temperatures are not constant and fluctuate with the photoperiod. In early and late insect seasons, temperatures can drop to below threshold temperatures where development essentially ceases. Threshold temperatures differ for different species and should be determined by raising insects at the extremely low temperatures. The lower threshold temperature for Protophormia terraenovae for egg hatch is 10.3°C ; for first instar larvae to molt to second instar larvae it …

Fall Webworm, Ryan S. Davis, Vincent P. Jones

All Current Publications

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.).

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.

Discerning Prey From Predator In Dragonflies, Melanie Lolier

Honors Theses

The dragonfly is a visual predator that feeds on small flying insects. Because of their high rate of hunting success, dragonflies must have the ability to efficiently discern prey and predator from natural surroundings. In this study, we investigated the extent to which visual flight-control neurons in dragonflies are able to differentiate stimuli that simulate prey items from those that simulate predators. To do this, we presented fourteen sets of rectangular stimuli varying in height, width, speed, and moved in four directions while recording extracellular neuronal responses from the ventral nerve cord. Each of the rectangular stimulus patterns was moved …

Foliage Dwelling Insect Composition In Three Stages Of Forest Regeneration, May 2011, Isa Betancourt

Tropical Ecology and Conservation [Monteverde Institute]

The International Tropical Timber Organization (ITTO 2002) estimated that secondary forest make up 60% of all tropical forests. By definition, that means that a majority of tropical forests have gone through succession in the recent past. In the present study I looked at differences between foliage dwelling insects at different stages of succession. A total of eight sweep samples were taken from a regenerating field (RF), a new growth forest (NGF), and an old growth forest (OGF) in San Luis, Puntaranes, Costa Rica to assess the diversity and evenness during the dry season and at an altitude of around 1200 …

Brown Marmorated Stink Bug, Erin Petrizzo, Diane G. Alston

All Current Publications

Brown marmorated stink bug (Order Hemiptera: Family Pentatomidae) (BMSB) was accidentally introduced into the eastern U.S. from Asia in the late 1990s. In 2001 it was officially identified in Pennsylvania, and has since spread along the eastern seaboard and westward into the Great Lakes region.

Revision And Reclassification Of The Genera Of Phalacridae (Coleoptera: Cucujoidea), Matthew Gimmel

LSU Doctoral Dissertations

The family Phalacridae is monographed at the genus level using modern phylogenetic and classification methods. A morphological matrix of 106 characters and 2063 base pairs of aligned 18S rDNA sequence data were analyzed both separately and in a concatenated matrix, using maximum parsimony, Bayesian methods, and maximum likelihood. The phylogenetic hypotheses were used to construct a new subfamilial classification for the family. I recognize eight subfamilies, including two described as new: Biophytinae Guillebeau 1894, Eustilbinae Guillebeau 1892, Ochrolitinae Guillebeau 1894, Olibrinae Guillebeau 1892, Olibroporinae, subfam. nov., Olibrosominae, subfam. nov., Phaenocephalinae Matthews 1899, Phalacrinae Guillebeau 1892. Twenty-eight new generic synonymies are …
