Lure for an insect trap has pigmented carrier gel which contains pheromone located in a tubular pigmented polyethylene container

摘要

The insect lure (30) has a pigmented polyethylene tubular container (40) closed at one end and having a tightly fitting sealing plug (42) in its other end. The plug (42) is also made of polyethylene and may be pigmented. The container holds a carrier gel (44) containing a pheromone which is slowly released and permeates through the polyethylene container into the air to attract male insects into a trap. The carrier gel (44) may be pigmented, and the pigment in it and in container (30) help prevent photo-degradation of the pheromone. Different pigments may be used to impart information The pigmented carrier provides a barrier to delay degradation of the pheromone due to UV radiation. The pheromone is released over, typically a period of about 13 weeks. The gel formulation comprises an mineral oil and one or more thixotropic agents. The thixotropic agent may be modified clay.
