Impacts Of Invasive Rats On Hawaiian Cave Resources, Francis G. Howarth, Fred D. Stone 2020 Bernice P. Bishop Museum

Impacts Of Invasive Rats On Hawaiian Cave Resources, Francis G. Howarth, Fred D. Stone

International Journal of Speleology

Although there are no published studies and limited data documenting damage by rodents in Hawaiian caves, our incidental observations during more than 40 years of surveying caves indicate that introduced rodents, especially the roof rat, Rattus rattus, pose significant threats to vulnerable cave resources. Caves, with their nearly constant and predictable physical environment often house important natural and cultural features including biological, paleontological, geological, climatic, mineralogical, cultural, and archaeological resources. All four invasive rodents in Hawai‘i commonly nest in cave entrances and rock shelters, but only the roof rat (Rattus rattus) habitually enters caves and utilizes areas in total ...


Utilizing Twitter To Communicate Risk After A Natural Disaster, Taylor K. Ruth, Teresa Suits, Ashley McLeod-Morin, Ricky W. Telg 2020 University of Nebraska-Lincoln

Utilizing Twitter To Communicate Risk After A Natural Disaster, Taylor K. Ruth, Teresa Suits, Ashley Mcleod-Morin, Ricky W. Telg

Journal of Applied Communications

Hurricane Michael hit the Florida panhandle as a category five hurricane on October 10, 2018. One of the risks after a hurricane is the spread of mosquito-borne disease due to standing floodwaters, which provide perfect breeding grounds for mosquitoes. People often turn to social media during times of crisis to receive up-to-date information. Therefore, there is a need to understand how to use social media to communicate about risks after a natural disaster. The purpose of this study was to explore how Twitter was used to communicate about mosquito control before and after Hurricane Michael and was guided by the ...

Cotton is an important crop that has made significant gains in production over the last century. Emerging pests such as the reniform nematode have threatened cotton production. The rare African diploid species Gossypium longicalyx is a wild species that has been used as an important source of reniform nematode immunity. While mapping and breeding efforts have made some strides in transferring this immunity to the cultivated polyploid species, the complexities of interploidal transfer combined with substantial linkage drag have inhibited progress in this area. Moreover, this species shares its most recent common ancestor with the cultivated A-genome diploid cottons, thereby ...


A Synergism Between Dimethyl Trisulfide And Methyl Thiolacetate In Attracting Carrion-Frequenting Beetles Demonstrated By Use Of A Chemically-Supplemented Minimal Trap, Stephen T. Trumbo, John Dicapua III 2020 University of Connecticut at Waterbury

A Synergism Between Dimethyl Trisulfide And Methyl Thiolacetate In Attracting Carrion-Frequenting Beetles Demonstrated By Use Of A Chemically-Supplemented Minimal Trap, Stephen T. Trumbo, John Dicapua Iii

EEB Articles

Volatile organic compounds derived from microbes recruit insects to carrion, shaping community assembly and ecological succession. The importance of individual volatiles and interactions between volatiles are difficult to assess in the field because of (1) the myriad compounds from decomposing animals, and (2) the likelihood that complex component blends are important for the final approach to carrion. On the assumption that searching insects may use simpler volatile cues to orient at a distance, we employed a chemically-supplemented minimal trap that uses test chemicals to attract from a distance and a minimal carrion bait to induce trap entry. Traps supplemented with ...


Lymesim 2.0: An Updated Simulation Of Blacklegged Tick (Acari: Ixodidae) Population Dynamics And Enzootic Transmission Of Borrelia Burgdorferi (Spirochaetales: Spirochaetaceae), Holly Gaff, Rebecca J. Eisen, Lars Eisen, Robyn Nadolny, Jenna Bjork, Andrew J. Monaghan 2020 Old Dominion University

Lymesim 2.0: An Updated Simulation Of Blacklegged Tick (Acari: Ixodidae) Population Dynamics And Enzootic Transmission Of Borrelia Burgdorferi (Spirochaetales: Spirochaetaceae), Holly Gaff, Rebecca J. Eisen, Lars Eisen, Robyn Nadolny, Jenna Bjork, Andrew J. Monaghan

Biological Sciences Faculty Publications

Lyme disease is the most commonly reported vector-borne disease in the United States, and the number of cases reported each year continues to rise. The complex nature of the relationships between the pathogen (Borrelia burgdorferi sensu stricto), the tick vector (Ixodes scapularis Say), multiple vertebrate hosts, and numerous environmental factors creates challenges for understanding and predicting tick population and pathogen transmission dynamics. LYMESIM is a mechanistic model developed in the late 1990s to simulate the life-history of I. scapularis and transmission dynamics of B. burgdorferi s.s. Here we present LYMESIM 2.0, a modernized version of LYMESIM, that includes ...


Terpenoid-Induced Feeding Deterrence And Antennal Response Of Honey Bees, NIcholas R. Larson, Scott T. O'Neal, Ulrich R. Bernier, Jeffrey R. Bloomquist, Troy D. Anderson 2020 Virginia Tech

Terpenoid-Induced Feeding Deterrence And Antennal Response Of Honey Bees, Nicholas R. Larson, Scott T. O'Neal, Ulrich R. Bernier, Jeffrey R. Bloomquist, Troy D. Anderson

Faculty Publications: Department of Entomology

Multiple interacting stressors negatively affect the survival and productivity of managed honey bee colonies. Pesticides remain a primary concern for beekeepers, as even sublethal exposures can reduce bee immunocompetence, impair navigation, and reduce social communication. Pollinator protection focuses on pesticide application guidelines; however, a more active protection strategy is needed. One possible approach is the use of feeding deterrents that can be delivered as an additive during pesticide application. The goal of this study was to validate a laboratory assay designed to rapidly screen compounds for behavioral changes related to feeding or feeding deterrence. The results of this investigation demonstrated ...

Do The Quality And Quantity Of Honey Bee-Collected Pollen Vary Across An Agricultural Land-Use Gradient?, Michael P. Simanonok, Clint R. V. Otto, Matthew D. Smart 2020 USGS, Northern Prairie Wildlife Research Center

Do The Quality And Quantity Of Honey Bee-Collected Pollen Vary Across An Agricultural Land-Use Gradient?, Michael P. Simanonok, Clint R. V. Otto, Matthew D. Smart

Faculty Publications: Department of Entomology

Pollen is the source of protein for most bee species, yet the quality and quantity of pollen is variable across landscapes and growing seasons. Understanding the role of landscapes in providing nutritious forage to bees is important for pollinator health, particularly in areas undergoing significant land-use change such as in the Northern Great Plains (NGP) region of the United States where grasslands are being converted to row crops. We investigated how the quality and quantity of pollen collected by honey bees (Apis mellifera L. [Hymenoptera: Apidae]) changed with land use and across the growing season by sampling bee-collected pollen from ...

Pereira, Premchand Gandra, Meghan L.F. Frey, Sarah Worden, Shannon Whitlock, Wendy Lo, Karl D. Schnelle, Jamie R, Lutz, Kenneth E. Narva, Blair Siegfried

Faculty Publications: Department of Entomology

Background: RNA interference (RNAi) triggered by maize plants expressing RNA hairpins against specific western corn rootworm ( WCR) transcripts have proven to be effective at controlling this pest. To provide robust crop protection, mRNA transcripts targeted by double-stranded RNA must be sensitive to knockdown and encode essential proteins.

Results: Using WCR adult feeding assays, we identified Sec23 as a highly lethal RNAi target. Sec23 encodes a coatomer protein, a component of the coat protein

(COPII) complex that mediates ER-Golgi transport. The lethality detected in WCR adults was also observed in early instar larvae, the life stage causing most of the crop ...

Milkweed (Asclepias Syriaca) Plant Detection Using Mobile Cameras, Koray Ozcan, Anuj Sharma, Steven P. Bradbury, Dana Schweitzer, Teresa Blader, Sue Blodgett

Natural Resource Ecology and Management Publications

Milkweed (Asclepias spp.) are host plants of monarch butterflies (Danaus plexippus). It is important to detect milkweed plant locations to assess the status and trends of monarch habitat in support of monarch conservation programs. In this paper, we describe autonomous detection of milkweed plants using cameras mounted to vehicles. For detection, we used both aggregated channel features (ACF) for running the detectors on embedded computing platforms with central processing unit and faster region‐based convolutional neural network (Faster R‐CNN) with a ResNet architecture‐based detector that is suitable for graphics processing unit optimized processing. The ACF‐based model produced ...

Employing Very High Frequency (Vhf) Radio Telemetry To Recreate Monarch Butterfly Flight Paths, Kelsey E. Fisher, James S. Adelman, Steven P. Bradbury

Natural Resource Ecology and Management Publications

The overwintering population of eastern North American monarch butterflies (Danaus plexippus) has declined significantly. Loss of milkweed (Asclepias sp.), the monarch’s obligate host plant in the Midwest United States, is considered to be a major cause of the decline. Restoring breeding habitat is an actionable step towards population recovery. Monarch butterflies are highly vagile; therefore, the spatial arrangement of milkweed in the landscape influences movement patterns, habitat utilization, and reproductive output. Empirical studies of female movement patterns within and between habitat patches in representative agricultural landscapes support recommendations for habitat restoration. To track monarch movement at distances beyond human ...


Functional Identification Of Fatty Acyl Reductases In Female Pheromone Gland And Tarsi Of The Corn Earworm, Helicoverpa Zea, Xiaoyi Dou, Aijun Zhang, Russell Jurenka 2020 Iowa State University

Functional Identification Of Fatty Acyl Reductases In Female Pheromone Gland And Tarsi Of The Corn Earworm, Helicoverpa Zea, Xiaoyi Dou, Aijun Zhang, Russell Jurenka

Entomology Publications

Most moths utilize sex pheromones released by the female to attract a mate. Females produce the sex pheromone in the pheromone gland in a biosynthetic pathway which consists of several key enzymes. Fatty acyl-CoA reductase is one of the key enzymes, which catalyzes the conversion of fatty acyl-CoA to the corresponding alcohol, playing an important role in producing the final proportion of each pheromone component. In Helicoverpa zea, (Z)-11-hexadecenal is the major sex pheromone component in female pheromone glands and previously a large amount of hexadecanal was also found in female and male tarsi. In our previous study, we ...

Estimating Arthropod Survival Probability From Field Counts: A Case Study With Monarch Butterflies, Tyler J. Grant, D. T. Tyler Flockhart, Teresa R. Blader, Richard L. Hellmich, Grace M. Pitman, Sam Tyner, D. Ryan Norris, Steven P. Bradbury

Entomology Publications

Survival probability is fundamental for understanding population dynamics. Methods for estimating survival probability from field data typically require marking individuals, but marking methods are not possible for arthropod species that molt their exoskeleton between life stages. We developed a novel Bayesian state‐space model to estimate arthropod larval survival probability from stage‐structured count data. We performed simulation studies to evaluate estimation bias due to detection probability, individual variation in stage duration, and study design (sampling frequency and sample size). Estimation of cumulative survival probability from oviposition to pupation was robust to potential sources of bias. Our simulations also provide ...


Balancing Disturbance And Conservation In Agroecosystems To Improve Biological Control, John F. Tooker, Matthew E. O'Neal, Cesar Rodriguez-Saona 2020 Pennsylvania State University

Balancing Disturbance And Conservation In Agroecosystems To Improve Biological Control, John F. Tooker, Matthew E. O'Neal, Cesar Rodriguez-Saona

Entomology Publications

Disturbances associated with agricultural intensification reduce our ability to achieve sustainable crop production. These disturbances stem from crop-management tactics and can leave crop fields more vulnerable to insect outbreaks, in part because natural-enemy communities often tend to be more susceptible to disturbance than herbivorous pests. Recent research has explored practices that conserve natural-enemy communities and reduce pest outbreaks, revealing that different components of agroecosystems can influence natural-enemy populations. In this review, we consider a range of disturbances that influence pest control provided by natural enemies and how conservation practices can mitigate or counteract disturbance. We use four case studies to ...
