Species-Specific Manipulation Of Microbially-Derived Volatiles By Burying Beetle Parents, Stephen T. Trumbo

EEB Articles

1. Hosts and microbes interact in dynamic relationships that can alter the volatile profile emitted by the microbial community. The extent to which closely related species diverge in these relationships is not well known.

2. Burying beetles associate with a rich microbial community that is present on their breeding resource, a small vertebrate carcass. Prior work demonstrated that Nicrophorus orbicollis manage the microbial community during parental care to alter the volatile profile emanating from the nest, reducing cues for competitors that would usurp the resource.

3. The present study extended this work to N. marginatus to first determine the distinctive …

Environmental Conditions Influencing Seasonal Population Dynamics Of Drosophila Suzukii (Diptera: Drosophilidae) In A Mid-Latitude Organic Farm Data, Eleanor Mccabe, Nicholas M. Teets, Jack J. Devlin, Megan E. Mccabe

Entomology Research Data

1. The local population dynamics of an invasive species are important for predicting impacts and determining proper management approaches. Temporal and spatial distribution can influence monitoring and treatment decisions and understanding climatic variables that affect population size can help predict peak population numbers.
2. Drosophila suzukii (Matsumara, 1931) is an invasive fruit pest, and its seasonal dynamics vary across its range. In this study, we conducted a three-year trapping study in conjunction with various modeling approaches to determine the environmental variables that influence population dynamics of D. suzukii across all seasons in central Kentucky.
3. Both male and female flies …

Data For "Linking Previous Experiences To Behavior And Health In The Honey Bee (Apis Mellifera)"", Rebecca R. Westwick, Clare C. Rittschof, Gavin P. Brackett, Cameron E. Brown, Bethany J. Ison, Zainulabbeudin Syed, Anna M. Foose

Entomology Research Data

An organism’s ability to respond to changing conditions can be vital to its success. Indeed, plasticity is a common feature of living organisms. Much of the research in this area, though, has focused on effects caused by environmental conditions. What has received relatively less attention is how social experiences and broader features of an organism’s social environment can lead to long-lasting changes in health and behavior. This knowledge gap exists despite the well-documented existence of health and behavioral effects after social interactions in certain taxa such as humans.

Social insects such as honey bees provide an excellent opportunity to better …

Caching Behavior In Burying Beetles, Stephen T. Trumbo

EEB Articles

Being the first to discover a resource can provide a competitive advantage (priority effect), even for an animal that is inferior in aggressive contests. Nicrophorus spp. (burying beetles) are known for caching a small vertebrate carcass as provision for their young, reducing volatile cues available to rivals by burying the carcass (vertical movement) and by altering the microbial community. A decomposing carcass, however, can leave cues (residues of decay) on soil and leaf litter that a burying beetle has less opportunity to neutralize. I investigated whether horizontal movement of the carcass by burying beetles, separating the carcass from soil at …

Suitability Of Native Milkweed (Asclepias) Species Versus Cultivars For Supporting Monarch Butterflies And Bees In Urban Gardens [Research Data], Daniel A. Potter

Entomology Research Data

Public interest in ecological landscaping and gardening is fueling a robust market for native plants. Most plants available to consumers through the horticulture trade are cultivated forms that have been selected for modified flowers or foliage, compactness, or other ornamental characteristics. Depending on their traits, some native plant cultivars seem to support pollinators, specialist insect folivores, and insect-based vertebrate food webs as effectively as native plant species, whereas others do not. There is particular need for information on whether native cultivars can be as effective as true or “wild-type” native species for supporting specialist native insects of conservation concern. Herein …

Predation On Stink Bugs (Hemiptera: Pentatomidae) In Cotton And Soybean Agroecosystems [Predator Gut Contents], Kacie J. Athey, John R. Ruberson, Dawn Olson, James D. Harwood

Entomology Research Data

Stink bugs (Hemiptera: Pentatomidae) are significant pests of cotton and soybeans in the southeastern United States with annual control costs exceeding $14 million in these crops. Three of the most prominent stink bug pests are the southern green (Nezara viridula), brown (Euschistus servus) and green (Chinavia hilaris) stink bugs. To determine trophic linkages between generalist arthropod predators and these pests, species-specific 16S molecular markers were designed and used to detect the presence of prey DNA in predator gut-contents. Over 2700 predators were collected over two growing seasons in cotton and soybean in southern Georgia …
