Efficacy of mating disruption treatment against spongy moth applied using an Unmanned Aerial Vehicle
Our objective was to develop a UAV-based mating disruption treatment method to control spongy moth, one of the most destructive forest pests in the US. Collaborating with ISCA Technologies (Riverside, CA, USA) and Aksata (Kfar Saba, Israel), we conducted a series of trial applications of spongy moth pheromone formulated as SPLAT® GM-organic.
We evaluated treatment efficacy for 10 weeks using the release-recapture method and compared it to the efficacy of the same treatment applied aerially using a piloted fixed-wing aircraft. Our findings indicate that UAV-applied mating disruption treatments achieve similar efficacy to treatments applied using piloted aircraft (with over a 90% reduction in male spongy moth catches in pheromone-baited traps compared to untreated control plots for at least 10 weeks).
Given the widespread use of the SPLAT® matrix in various formulations, our project's results may hold relevance for mating disruption control strategies targeting other pests, thereby contributing to the advancement of integrated pest management practices.

Baode Wang
Solar powered portable UV light traps for detection and surveillance of the flighted spongy moth complex
We developed portable UV-A light traps powered by solar-charged lithium-ion batteries to detect and monitor Lymantria moths. These traps effectively captured both male and female Lymantria dispar asiatica (a Flighted Spongy Moth Complex subspecies) in various locations. While less effective than pheromone traps for capturing male Lymantria dispar moths, our light traps show promise for FSMC monitoring, particularly in pinpointing smaller areas where egg-laying female moths may be present. Ongoing research aims to enhance target moth capture while reducing unintended by catch

Ann Hajek
Spongy Moth: A tale of two pathogens
The spongy moth and associated larval pathogens (a fungus and virus) and parasitoids (mainly 4 species) have all been introduced to North America. The virus was the dominant natural enemy until the fungus was first seen in 1989, and subsequently spread, outcompeting the virus. The fungus and parasitoids provide significant mortality in low density populations while in outbreaks, all three types of natural enemies are active. The virus is mass produced for spongy moth control in environmentally sensitive areas. While the fungus is not mass produced, cadavers of larvae dying from infections have been collected and moved to accelerate spread.
Dr. Hajek has been on Cornell University campus for 40 years; 10 working in a research institute and 30 as a professor in the Department of Entomology and she recently retired. Throughout her career, she conducted research on insect parasites and pathogens, principally working on fungal and viral pathogens and parasitic nematodes. Dr. Hajek has worked in a diversity of invasive insect systems but her most long-term and intensive research has been investigating pathogens of Lymantria dispar. Her work on the L. dispar system has ranged from molecular and cellular to organismal and studies of epizootiology and ecology.

The Impact of Weather on the Accuracy of Phenological Predictions for the European Spongy Moth
The accuracy of the spongy moth life stage (GLS) model has not been evaluated on a large geographic scale. Using a multi-year dataset, we tested the model's performance by comparing GLS predictions of male moth flight with observed captures across the invasion's leading edge, which includes various climatic conditions. We also examined how abiotic factors like temperature and precipitation influence the model's prediction accuracy. Our results offer insights into the model's spatiotemporal robustness and highlight factors that affect its performance. These findings have important implications for improving the effectiveness of STS interventions.
Grace Efua Amponsah is a research assistant and a master's student in the Ohio State University. She is working towards optimizing the management of spongy moths exacerbated by climate change in the United States.

Meeting citizen concerns with hard data: does Btk application reduce biodiversity? Preliminary insights from 2024 studies in Minnesota
This study examines the potential non-target effects of Bacillus thuringiensis kurstaki (BtK) applications on insect biodiversity in Minnesota. In 2024, data were collected from 16 sites—8 treated with BtK and 8 controls—focusing on lepidopteran abundance and richness, as well as arthropod populations. Preliminary analyses show no significant impact of BtK on non-target Lepidoptera or overall insect diversity. These findings suggest that BtK application does not significantly reduce biodiversity, providing evidence to address public concerns. Ongoing research will explore longer-term effects and broader ecological implications.
Sayesha Khanna’s academic journey has taken her across continents, from her Bachelor’s in India to earning a European Commission-funded scholarship in Plant Health, which allowed her to study in Spain, France, and the Netherlands. Currently, she is a PhD student in Brian Aukema’s lab at the University of Minnesota, where her research focuses on phenology of the spongy moth and investigating the non-target effects of BtK sprays used in its control. Having just entered her second year of PhD, she is eager to dive deeper into understanding how ecological systems respond to these pest management strategies.
Dylan Parry
Are lab-strain spongy moth an accurate proxy for natural populations?
Ecologists have long used the so-called New Jersey Standard Strain (NJSS) spongy moth as a surrogate for wild populations in a wide array of ecological, toxicological, and physiological experiments. This strain has been under continuous culture by USDA-APHIS for more than half a century, is highly inbred, and has undergone accidental and deliberate selection for a variety of traits advantageous in mass captive rearing, but surprisingly few studies have evaluated its suitability as a proxy for wild spongy moth. In comparisons, we found that NJSS spongy moth behavior, growth, development, phenology, and cold tolerance all departed significantly from with wild sourced populations. Despite the convenience and genetic homogeneity, researchers should more carefully consider their questions before using NJSS as a stand in for natural populations.
Dylan is an ecologist specializing in biological invasions and insect conservation. He has worked extensively with spongy moth, Sirex woodwasp, and other insect invaders as well as both woody and perennial invasive plants. Ongoing projects in his lab include efforts to understand the resurgence of browntail moth, biological control of invasive plants, linkages between invasion and climate change, synergism between exotic European and Asian earthworms and plant invaders, and efforts to understand adaptive change in spongy moth populations. He also teaches undergraduate and graduate courses on the ecology and management of invasions.
