Nesting Biology Of Pachymenes Ghilianii (Spinola, 1851) (Hymenoptera: Vespidae: Eumeninae: Eumenini) In Panama, Jean Carlos Abrego, Bolivar R. Garcete-Barrett, Alonso Santos Murgas

Insecta Mundi

The nesting biology of the potter wasp Pachymenes ghilianii (Spinola) (Hymenoptera: Vespidae: Eumeninae) is described based on observations made in the Cerro Turega Hydric Reserve, Penonome, Panama. The collection of building material, the architecture of the nest, the process of building a cell and cell provision with geometrid larvae (Lepidoptera: Geometridae), and the emergence time of the adults are recorded.

Phorodon Cannabis Passerini (Hemiptera: Aphididae), A Newly Recognized Pest In North America Found On Industrial Hemp, Whitney S. Cranshaw, Susan E. Halbert, Colin Favret, Kadie E. Britt, Gary L. Miller

Insecta Mundi

Phorodon cannabis Passerini (Hemiptera: Aphididae: Macrosiphini) is reported for the first time as a pest of Cannabis L. crops in North America. The insect has been confirmed from fields of industrial hemp in Colorado and Virginia and has been found present within greenhouses in at least several American states and one Canadian province. The generic position of the aphid species is discussed and other known members of the genus are ruled out. Phorodon cannabis is placed in genus Phorodon Passerini and subgenus (Diphorodon Börner). Phorodon persifoliae Shinji is transferred to Hyalopterus Koch as a nomen dubium.

Science At Engineer Cantonment, Hugh H. Genoways, Brett C. Ratcliffe, Carl R. Falk, Thomas E. Labedz, Paul R. Picha, John R. Bozell

University of Nebraska State Museum: Mammalogy Papers

Conclusions

It is our contention that Thomas Say, Titian Peale, Edwin James, and their colleagues of the Stephen Long Expedition of 1819–1820 were heavily engaged in scientific research, which took the form of the first biodiversity inventory undertaken in the United States. This accomplishment has been overlooked both by biologists and historians, but it should rank among the most significant accomplishments of the expedition. The results of this inventory continue to inform us today about environmental, faunal, and floral changes along the Missouri River in an area that is known to be an ecotone between the deciduous forests of the …

U.S. National Collection Of Scarabs At Unsm, Brett Ratcliffe

Department of Entomology: Faculty Publications

The Department of Entomology of the Smithsonian Institution (SI) National Museum of Natural History granted an Offsite Collection Enhancement Pogram (OEP) to the State Museum at the University of Nebraska (UNSM). TheOEP consists of the renewable ten-year loan of a large collection which is bound to a detailed, 19 point Memorandum of Understanding between both parties and signed off institutionally by Museum Directors. The basic idea is that if part of the U.S. National Collection has no ongoing resident active research and there exists a center of expertise at another institution, it is most prudent to allow this off-site center …

Review: Application Of Tick Control Technologies For Blacklegged, Lone Star, And American Dog Ticks, Alexis White, Holly Gaff

Biological Sciences Faculty Publications

Tick population control technologies have been studied for several decades but no method is successful in all situations. The success of each technology depends on tick species identity and abundance, host species identity and abundance, phenology of both ticks and hosts, geographic region, and a multitude of other factors. Here we review current technologies, presenting an overview of each and its effect on three common tick species in the eastern United States: blacklegged ticks (Ixodes scapularis (Say; Ixodida: Ixodidae)), lone star ticks (Amblyomma americanum (Linnaeus; Ixodida: Ixodidae)), and American dog ticks (Dermacentor variabilis (Say; Ixodida: Ixodidae)). Moreover, …

A Comparison Of Community Structure In Regulated And Unregulated Reaches In The Upper Eel River, California, Lara Stephanie Jansen

Cal Poly Humboldt theses and projects

Flow regulation of rivers by impoundments and diversions can reduce hydrological variability. As a result, densities of algae and benthic macroinvertebrates often increase, but many sensitive taxa are lost, causing shifts across the food web. In Northern California, dams that reduce winter peak floods can result in the primary consumer community becoming dominated by grazers that are relatively invulnerable to predation, which can reduce the amount of energy transferred up the trophic levels. The steeper slope of the spring hydrograph recession limb downstream of a dam can also greatly impact instream diversity of periphyton, invertebrates and fish. The dam and …

Molecular Candidates For Blocking The Transmission Of Vector-Borne Diseases, Ashish Naresh Vora

Biological Sciences Theses & Dissertations

Vector-borne diseases (VBDs) require urgent attention as they have a high mortality rate, with 700,000 people dying in a year as of 2017. So far, extremely few reliable vaccination strategies and solutions have emerged. Transmission blocking vaccines are one among many solutions available to manage the control of VBDs. These require identification of both vector and pathogen molecules that play important roles in the transmission, dissemination and establishment of VBDs. Our strategy is to characterize these candidates that play important roles in vector-host-pathogen interactions. This manuscript presents two such studies identifying the participation of two arthropod molecules in vector-host-pathogen interactions. …

Using An In Vitro System For Maintaining Varroa Destructor Mites On Apis Mellifera Pupae As Hosts: Studies Of Mite Longevity And Feeding Behavior, Noble I. Egekwu, Francisco Posada, Daniel E. Sonenshine, Steven Cook

Biological Sciences Faculty Publications

Varroa destructor mites (varroa) are ectoparasites of Apis mellifera honey bees, and the damage they inflict on hosts is likely a causative factor of recent poor honey bee colony performance. Research has produced an arsenal of control agents against varroa mites, which have become resistant to many chemical means of their control, and other means have uncertain efficacy. Novel means of control will result from a thorough understanding of varroa physiology and behavior. However, robust knowledge of varroa biology is lacking; mites have very low survivability and reproduction away from their natural environment and host, and few tested protocols of …

Diet Breadth Evolution And Diversification Of A Generalist Insect Herbivore, Mayra Cadorin Vidal

Electronic Theses and Dissertations

Insect herbivores are one of the most diverse groups of multicellular organisms, and the vast majority are specialists, which feed on only a few plant species. The factors that cause some herbivores to be specialists and others to be generalists are still unclear. It is known that the selective forces from natural enemies (top-down) and the host plants (bottom-up) influence an herbivore's diet breadth. In my meta-analysis evaluating the relative important of top-down and bottom-up forces on insect herbivore fitness, I found that herbivores usually have greater performance on better quality plants and in the absence or reduction of enemy …

Residual Contact Toxicity And Repellence Of Cupressus Lusitanica Miller And Eucalyptus Saligna Smith Essential Oils Against Major Stored Product Insect Pests, Philip K. Bett, Arop L. Deng, Joshua O. Ogendo, Samuel T. Kariuki, Maud Kamatenesi-Mugisha, Joel M. Mihale, Baldwyn Torto

All Peer-Reviewed Publications

In an effort to find eco-friendly alternatives to synthetic pesticides in grain storage, residual contact toxicity and repellence of Cupressus lusitanica and Eucalyptus saligna leaf essential oils were evaluated against adult Tribolium castaneum, Acanthoscelides obtectus and Sitophilus zeamais. In bioassays, oil was applied at 0.00, 0.05, 0.10, 0.15 and 0.20% v/w to wheat and bean grains and stored for 30–120 days after which test insects were introduced into sub-samples of treated grains. Both oils at 0.20% v/w and 120 days grain storage duration caused a mortality of 5.0–65.0% in test insects whereas in the repellence bioassay, at same doses and …
