Allison entered the Master of Science program in Entomology in 2013, but her ties to the Hoddle lab stretch back much farther. While an undergraduate, she worked in Dr. Paul de Ley's lab researching marine and freshwater nematode ecology. After receiving her bachelor's degree in 2008, she was hired by the Hoddle lab and has worked on various projects, including glassy-winged sharpshooter, gold spotted oak borer, and Asian citrus psyllid (ACP) research. Her graduate research focuses on the biology of parasitoids targeting ACP for use in biological control.

Current Projects



Asian Citrus Psyllid

Asian citrus psyllid (ACP) is an efficient vector of the citrus disease huanglongbing (HLB)... More...



Tamarixia radiata

An Eulophid wasp and primary parasitoid of Asian citrus psyllid (ACP) from Punjab, Pakistan.



Diaphorencyrtus aligarhensis 

An Encyrtid wasp and primary parasitoid of Asian citrus psyllid (ACP) from Punjab, Pakistan. 


Research Interests

For the past year, I have been working primarily on identifying various parasitoids and hyperparasitoids within the ACP ecological complex in Pakistan. In December 2013, I completed host specificity testing on the primary parasitoid Diaphorencyrtus aligarhensis, which we are intending to use as a second option for biological control of ACP in California. Additionally, I have confirmed the roles of several hyperparasitoids associated with ACP, which could have potential ramifications to current and ongoing biological control efforts. My current and future research will focus on describing the various reproductive and life history traits of the parasitoid Psyllaphycus diaphorinae, which no one (to date) has ever worked with before.
