Laboratory evaluation of imported sex pheromone lures used for monitoring three lepidopterous pests in Egypt [electronic resource].

Includes references.

Three imported pheromone lure types used for monitoring cotton leaf Worm, Spodoptera littoralis, black cutworm, Agrotis ipsilon, and American bollworm, Heliothis armigera were evaluated in this study. Gravimetric analysis indicated that the three tested lures have low tendency to absorb humidity from environment. Residual analysis by gas chromatography showed that the three lure types contain proper type and ratio of pheromone isomers specific for each pest. However, S. littoralis lures aged in field for 30, 60 and 90 days were the most efficacious in releasing pheromone isomers with a proper ratio followed by A. ipsilon. H armigera lures were the least efficient at releasing their pheromone contents. The overall results suggested that for success of using pheromone for pest monitoring as a component of IPM in Egypt, more careful studies on performance of the range of imported commercial pheromone lures under Egyptian environments are needed.
