2016 Scholarship Recipient
Kelsey Schall is a third year Ph.D. candidate in the Entomology Department at the University of California, Riverside. In 2009 she graduated from the University of California, Santa Barbara as a Regent’s Scholar with a B.A. in Biology from the College of Creative Studies. Her interest in insects started with a high-school entomology course and matured throughout her undergraduate studies. As a student researcher at UCSB she became fascinated by parasitic interactions, first studying them in marine life, and later through an independent insect biodiversity survey at the Carpinteria Salt Marsh Reserve. Her strong interest in parasitology and entomology made biocontrol a natural fit for a graduate-level program.
Following acceptance into the Entomology Ph.D. program at the University of California, Riverside in 2013, Kelsey began her research on biocontrol of ant-tended honeydew-producing insects infesting California’s iconic citrus crop. The most significant of these pests, the Asian citrus psyllid, Diaphorina citri, in combination with its vectored disease, huanglongbing (caused by the CLas bacterium) poses an unprecedented threat to the state’s $3-billion-a-year citrus industry. Substantial psyllid population reduction is necessary to curtail disease spread through commercial production areas. As part of a comprehensive approach aimed at long-term integrated pest management of D. citri in California, Kelsey’s research investigates the efficacy of ant control strategies for augmenting D. citri biocontrol. These strategies focus on suppression of the Argentine ant, Linepithema humile, the most ubiquitous and problematic tramp ant found in Southern California citrus.
In upcoming work she will test a novel, low-toxicity and biodegradable baiting system for L. humile in citrus. Baits and application methodologies derived from this research could be expanded to other valuable crops that suffer greatly from ant-tended pests (i.e., wine grapes and tree nuts), considerably improving biological control across California and upholding its historical precedent of strongly successful IPM programs.
Kelsey will utilize funds from the Harry Scott Smith Biological Control Scholarship to purchase ant bait stations and a field vehicle to travel to her experimental citrus groves stationed across Southern California. The award will additionally support her travel to an international academic meeting (International Congress of Entomology, Orlando 2016) as well as several industry meetings hosted by organizations such as the Professional Association of Pesticide Applicators, UC Master Gardeners, and the Citrus Research Board’s ACP BioControl Taskforce. These opportunities will allow her to continue to extend her critical, practical research findings to both members of the academic community and end-users –California’s pesticide applicators and growers.
Kelsey's scholarship is made possible in part by these 2016 donations
