Research Activities & Interests

Based at a remote research station 2.5 hours away from campus, my research focuses on developing IPPM programs in tree fruits that utilize selective insecticides (i.e., IGR's, Bt's, pheromone disruption) to control lepidopteran pest species while promoting biological control of secondary pests. Bee and syrphid identification and natural history in orchards and surrounding landscape has been a major focus over the last 10 years with over 200,000 bee collected (approximately250 species) and data-based as baseline information over time to measure biodiversity losses due to climate change, pesticide use, or possibly conserved through IPPM practices such as changes in pesticide recommendations or the inclusion of floral resource plantings into the landscape around orchards.  In this I work closely with the Frost Entomological Museum on campus. I manage large populations of the introduced Japanese Orchard Bee (Osmia cornifrons) that we use as a surrogate for non-Apid bee in understanding pesticide effects. We are measuring field realistic doses of insecticides and fungicides in orchards using typical fruit grower equipment on the 80 acres of commercial fruit plantings at the station.  We use this information to modify application timing or pesticide selection to better protect the wild pollinators that provide most of the pollination of Pennsylvana's 22,000 acres of apple and 3,500 acres of peach.  In my lab, using these realistic doses we measure in the orchards, we are testing the lethal and sublethal effects of pesticides on this bee in comparison to the honey bee to better understand variable toxicity between the two species and the mechanisms involved.  With regular introduction of invasive species that affect orchards (e.g. brown marmorated stink bug, spotted wing drosophila, spotted lanternfly and others), I became increasingly involved with the search for native predators and parasitoids to host shift and help control these pests in addition to testing various insecticides for efficacy and integrating them into existing IPPM programs for multiple crops.
