Talk at CES on 22 March 2017 at 4:00 pm titled "Ejaculate dynamics in tephritid flies" by Dr. Diana Pérez-Staples from Universidad Veracruzana, Xalapa, Mexico
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.
