When an invasive cockroach species is introduced into a new environment, many questions arise, including “What impact will they have on the established pest species?” In many areas of the western USA, oriental cockroaches (Blatta orientalis) are being displaced by Turkestan cockroaches (Periplaneta lateralis, aka Shelfordella lateralis and Blatta lateralis). What should PMPs know about this new cockroach species? How are PMPs and the research community adapting? Andrew Sutherland, Ph.D, BCE, from the University of California, will do a deep dive into biology, ecology, and management of the Turkestan cockroach and will also review some other invasive cockroach species.
