Females can become highly cannibalistic in the presence of other females.
Doctoral candidate Yao Hua Law (right), who studies with major professor Jay Rosenheim, UC Davis Department of Entomology, will speak on "My Neighbors Drive Me Cannibalistic: Mechanisms of Density-Dependent Cannibalistic Behavior and its Effects on Population Dynamics" at a seminar from 12:10 to 1 p.m., Wednesday, Oct. 6 in 122 Briggs Hall.
The lecture, which will be his exit seminar, will focus on the egg cannibalism behavior expressed in the generalist predator, Geocoris pallens.
It's also known as the "big-eyed bug."
G. pallens females are weakly cannibalistic when alone, but become highly cannibalistic in the presence of other females, he said. "I will discuss the possible mechanisms of this behavior, as well as the implications of this behavior for the arthropod community that G. pallens interact with," said Law, who will be introduced by Rosenheim.
Law’s lecture will be webcast live (http://uc-d.na4.acrobat.com/ucsn1/) and then archived on the UC Davis Department of Entomology website. The seminars are chaired by assistant professors Neal Williams and Louie Yang.
The fall seminars began Sept. 29 and will continue through Dec. 3. Most are held from 12:10 to 1 p.m. on Wednesdays. See schedule.
