The efficacy of heat treatment for drywood termite management
In collaboration with a local heat remediation company, we develop and evaluate a step-by-step guidelines for managing drywood termites using heat technology. The case study is conducted in a condominium unit in Honolulu, Hawaii.
Physical barriers for subterranean termite management
We evaluate the efficacy of a physical barrier against subterranean termites under laboratory conditions. We are hoping to continue the theme of “least-toxic termite control” which was begun by Dr. Minoru Tamashiro (Professor Emeritus, PEPS, CTAHR, University of Hawaii).
Novel ant control techniques
In 2017, at UC Riverside, we developed and evaluated biodegradable hydrogel bait made from alginate, which comes from brown seaweed, that could potentially revolutionize ant management in different environmental settings, i.e., agricultural, urban, natural settings. Hydrogel bait encapsulates sucrose solution containing tiny amounts of pesticide, allowing ants to feed from the hydrogel surface. Compared to conventional sprays, the use of this novel baiting technique dramatically reduced the amount of pesticides applied to the environment.

The roles of the queen, brood and worker castes in the colony growth dynamics of the pharaoh ant, Monomorium pharaonis

We conducted studies on ant social regulation (caste influences), nest relocation behavior in response to a variety of disturbances to a nesting site, and the effects of a juvenile hormone analogue on egg production, and microscopic morphology in the ovaries of the Pharaoh ant, Monomorium pharaonis, one of the most successful invasive pest ants. We also conducted studies on the necrophobic behavior of Asian subterranean termite, Coptotermes gestroi.
