2022 Working Groups

1890 Small Farm Integrated Pest Management for Underserved Audiences Working Group

PI: Dr. Daniel Collins
Alcorn State University, Mississippi
Amount Funded: $28,915

Socially disadvantaged small farmers are more vulnerable to losses due to lack of IPM knowledge, limited resources, and challenging circumstances for managing plant pests and most IPM projects focus on large farms.  Yield losses due to sub-tropical climate conditions, weather extremes (e.g., hurricanes, drought, tornados), and pest outbreaks have been substantial. Alcorn is taking the lead in organizing a multi-state-territory interdisciplinary IPM working group of 1890 Land-Grant Universities and uniting with a diverse group of small farmers, entrepreneurs, students, and agricultural alliances to address key agricultural problems and identify IPM research and extension needs of small farmers to help facilitate the economic development of small farmers. 

Emerging Viruses in Cucurbits Working Group

PI: Dr. Rebecca Melanson
Central Mississippi Research & Extension Center
Amount Funded: $38,000

During the past 25 years, viruses infecting cucurbit crops, including cucumbers, melons, pumpkins, squashes, and watermelons, have emerged in the cucurbit producing areas of the United States at an alarming rate. The Emerging Viruses in Cucurbits Working Group is improving communication and virus knowledge across the industry as well as developing strategies to successfully identify and mitigate virus threats to cucurbit production in the United States and includes regional, national, and international members from all sectors of the cucurbit industry.

Mosquito BEACONS - Biodiversity Enhancement And Control of Non-native Species

Dr. Yoosook Lee
University of Florida – Florida Medical Entomology Laboratory
Amount Funded: $40,000

In the southeastern United States, several mosquitoes of medical and veterinary importance are invasive mosquito species and their presence increases the risk of arbovirus transmission to humans and livestock. This continuing working group – Mosquito BEACONS: Biodiversity Enhancement And Control of Non-native Species – implements an IPM approach for the monitoring and control of invasive mosquito species in the Southern region by bringing together mosquito control, public health, private pest control, and academics to raise awareness of invasive mosquito species issues in the southern region. BEACONS is working to improve communication and collaboration opportunities, describe the surveillance capacity for invasive and non-native taxa, and train a cadre of IPM professionals across the southern region.

2022 Capstone Projects

Integration of Natural Enemies into Sugarcane Aphid IPM in Sorghum Using Spatial Modeling to Forecast Risk and Guide use of IPM tools

Dr. Blake Elkins
Texas A&M
Amount Funded: $30,000

The sugarcane aphid (Melanaphis sorghi) is an important and outbreak-prone insect pest of sorghum. This project aims to synthesize previously acquired spatial data on sugarcane aphid and its natural enemies to develop a quantitative spatially explicit model to forecast risk and guide use of IPM tools. This project links to a recent course (regional scale) model designed to assign region-specific outbreak risk of sugarcane aphid as affected by natural enemies and influences by agro-landscape and weather conditions. This project will produce a region-specific IPM guidance document and a more local risk/guidance tool as data allows. 

Conservation Biological Control of Crapemyrtle Bark Scale through Education and Demonstration

Dr. David Held
Auburn University, Alabama
Amount Funded: $30,000

Crapemyrtle bark scale (CMBS), is an invasive scale that reduces the aesthetic value of crapemyrtle, decreasing its bloom size and vigor, causing branch dieback, and producing honeydew which leads to trunks and branches darkened with sooty mold. This Capstone project will combine the outcomes of Held Lab’s recent research with visual attractants and low risk alternative controls for management of CMBS in urban landscape with a goal to produce an innovative and actionable alternative to systemic insecticides for CMBS management, reducing preventive and indiscriminate use of neonicotinoid insecticides in urban landscapes for CMBS management.

2022 Seed Projects

Integrating Pest and Pollinator Management Strategies for Ornamental Plant Production

Dr. Bernadette Mach
University of Florida
Amount Funded: $29,774

Many IPPM strategies rely on comprehensive toxicological data to understand the susceptibility of pollinators to insecticides, the severity of potential adverse impacts, and the duration of hazardous effects with most pollinator toxicological data focusing on bee species. Lepidopterans (i.e. butterflies and moths) pollinate plants as adults, fulfill important ecological functions as herbivores, and play a major role in supporting food webs as larvae. Using the monarch butterfly-oleander aphid-milkweed system is an ideal model for developing IPPM strategies for beneficial lepidopteran conservation, this project will identify insecticide active ingredients, application rates, treatment windows, and management programs that are compatible with beneficial insect conservation, but control key pests.

Developing Cultivar Resistance as a Management Tool Against Aerial Blight on Soybean

PI: Dr. Alejandro Del Pozo-Valdivia, Virginia Tech

Amount Funded: $30,000

Mealybugs have become a key pest for open-field nurseries growing ornamental plants in Virginia. Hundreds of thousands of dollars have been lost due to the inability to sell mealybug infested ornamental plants, especially when selling them across State lines. In addition, nursery growers are spending significant amounts of money on their pest management budgets to control this insect during the past three years. Nursery growers in Virginia and elsewhere have a need for science-based solutions to successfully manage this insect. 

This seed project is proposing using boxwood as a case study to promote the scouting of this key pest in the field, as well as understanding the preference of mealybugs for different boxwood cultivars. Having an established monitoring method for this pest will impact insecticide use, reducing non-target effects on the beneficials in affected systems. Knowing what cultivars are more susceptible to mealybugs will also inform growers on how to prioritize monitoring by scouting the most susceptible boxwood cultivars first. And, to maximize chemical control of this pest, one additional goal of this project is to evaluate the efficacy of several insecticide active ingredients and regimes under field conditions to reduce mealybugs populations in boxwood. Ultimately, generated information from this proposal will inform mealybug management programs for nurseries in Virginia and across the region.

Investigating Insecticide Concentrations in Peach Extrafloral Nectaries

PI: Dr. Brett Blaauw
University of Georgia
Amount Funded: $23,897

While most peach varieties are self-pollinating, many varieties of peaches have nectar producing lobes on their leaves, known as extra-floral nectaries (EFNs) that are attractive to insects and lure pollinators into the orchards even after crop bloom. This subsequently has the potential to subject the EFN visiting pollinators to commonly used systemic insecticides. The increased risk to insects visiting peach orchards may affect the insect community of other pollinator-dependent crops nearby within the region. This project aims to determine whether neonicotinoids are present in EFN of peaches when applied at standard dose rates over time, improving the sustainability of insect management programs and mitigate non-target effects on pollinator communities.

Herbicide Injury Symptoms, Diagnostics and Continuing Education

PI: Dr. Wesley Everman
North Carolina State University
Amount Funded: $29,837

Non-target herbicide injury has become increasingly problematic in agronomic and horticultural crops, and in urban landscapes. Crop injury results from drift, contaminated compost and hay, manure, composts, grass clippings, contaminated irrigation water, and misapplication. Content including an overview of herbicide injury diagnostic procedures, herbicide modes-of-action and symptomology, common routes of exposure, and response strategies for growers will be disseminated through in-person events for Cooperative Extension agents and Department of Agriculture pesticide inspectors while also offering public asynchronous content.

Using Boxwoods as Case Study for Implementing Japanese Maple Scale IPM

PI: Dr. Alejandro Del Pozo-Valdivia
Virginia Tech
Amount Funded: $30,000

The Japanese maple scale, or JMS, is a key pest for open-field nurseries growing ornamental trees and shrubs in Virginia. Hundreds of thousands of dollars have been lost due to the inability to sell JMS infested ornamental plants, and nursery growers are spending significant amounts of money on their pest management budgets to control this insect. This seed project uses boxwood as a case study to promote the use of the tape method for monitoring JMS crawlers, as well as understanding the preference of JMS for different boxwood cultivars as Nursery growers in VA and elsewhere have a need for science-based solutions to successfully manage this scale.
