Investigation of the sex pheromone of raspberry cane midge - HH3124SSF

Description
Raspberry cane midge is an important pest of raspberry, controlled currently by routine sprays of chlorpyrifos in spring. The purpose of the proposed research is to undertake a preliminary investigation of the identity of the sex pheromone of the raspberry cane midge. The pheromone, which is emitted by females to attract males for mating, may be used for monitoring the pest to determine if and when to spray. If the pheromone is sufficiently attractive and stable and inexpensive to synthesise, it may prove cost-effective to use it for control by mating disruption, mass trapping or lure and kill approaches. This will reduce raspberry grower’s dependence on chlorpyrifos, an OP insecticide residues of which occur in 22% of samples of UK produced raspberry fruit (KG Fruits residues data). However, the purpose of this project is only to make a preliminary identification of the cane midge’s sex pheromone. In an ongoing Defra funded project (HH3114TTF), East Malling Research (EMR) and Natural Resources Institute (NRI) have very recently identified the sex pheromone of the apple leaf curling midge, a novel pheromone chemical group which has proven highly attractive to apple leaf midge males. The identification of this new group of pheromones will make it easier to identify the pheromones of these other species We are also close to completing the identification of the sex pheromone of the blackcurrant leaf midge.
Objective
1. To conduct a preliminary investigation to determine the feasibility of identifying the sex pheromone of the raspberry cane midge.
2. To determine the chemical structures of any active compounds detected.
