Abstract:
The Sterile Insect Technique (SIT) consists of the mass-production, sterilization and release of target pest insects in an affected area. Once released, sterile males mate with wild females rendering them infertile. The effectiveness of SIT depends on sterile males performing both pre-copulatory and post-copulatory behaviours in order to compete with wild males. In SIT controlled Tephritid flies, attention has been focused on pre-copulatory behaviours with relatively fewer studies on post-copulatory behaviours such as sperm transfer and the ability of males to inhibit females from remating. Here I review ejaculate dynamics in tephritid flies of economic importance, and focus on the factors that can modulate post-copulatory mating behavior.
Speaker Bio:
Bio: Diana Pérez-Staples is a Research Professor at the Universidad Veracruzana in Xalapa, Veracruz, Mexico, where she has been a faculty member since 2008. Previously she was a postdoc at Macquarie University, Australia. Diana completed her PhD at the Institute of Ecology (INECOL, Mexico), and her masters at the National Autonomous University of Mexico (UNAM). She received her undergraduate degree from Reed College, USA. Her research is focused on the sexual behaviour of tephritid fruit flies and other insect pests, and on improving current control methods. Diana has received the L’Oréal-UNESCO fellowship for Women in Science and the Kathleen S. Anderson Award for Promising Biologists. She is currently based in Kavita Isvaran´s laboratory as a visiting professor during her sabbatical.
