Program Information: October 2022

PAST EVENTS > OCTOBER 23-27, 2022

The workshop was held at Beit Maiersdorf, The Hebrew University, Mount Scopus, Jerusalem, Israel. All talks were held in Mandel auditorium.

PROGRAM INFORMATION

The Workshop had three distinct, primary purposes/objectives:

A. To facilitate discussion within and between the groups of experts who focus on insect seminal proteins, sperm and pheromones, on female reproductive tracts, nervous systems, and reproductive behavior with the goal of exchanging information, obtaining collegial input from a variety of perspectives and coordinating investigations and collaborations across questions and organisms.

B. To foster interaction between Israeli and non-Israeli scientists in fields including the reproductive control of insects of relevance to agriculture, or reproductive biology in organisms beyond insects.

C. To share the most up-to-date scientific knowledge, to push the frontiers of knowledge and to provide answers/guidance to current and future challenges we face in field of pest control, specifically, for invasive and emerging pests.

The invited speakers covered diverse basic and applied research fields within reproduction, selected for their unique and complementary research angles. The exchange across interdisciplinary borders allows for new overarching ideas to be developed through cross-fertilization of techniques employed and insights harbored by each field.
