Research Project: Efforts to Disrupt Winterform Re-entry Using Repellents or Attractants

Location: Temperate Tree Fruit and Vegetable Research

Project Number: 2092-22430-001-39-T
Project Type: Trust Fund Cooperative Agreement

Start Date: Jul 1, 2012
End Date: Jun 30, 2014

Test repellent and attractant as means to disrupt colonization of pear orchards by overwintered pear psylla, and to disrupt or delay mating of overwintered psylla.

Laboratory and field trials will be done using a psyllid repellent being developed by ISCA Technologies, to determine if the product is repellent to pear paylla. Laboratory assays will be done using a sex pheromone attractant of pear psylla to determine whether saturation of the air with this product leads to delays in males locating females, and in inseminating females.
