Abstract
The use of semiochemicals (behaviour-modifying chemicals) as components of a control strategy for Sitona lineatus (Coleoptera: Curculionidae), was investigated in two field trials. The semiochemicals used were 4-methyl -3,5-heptanedione, the aggregation pheromone of S. lineatus, and an antifeedant formulation of neem oil, from the neem tree, Azadirachta indica (Meliaceae). The results showed that, in small-plot trials, insect damage to the crop could be decreased by the application of an antifeedant. Plots baited with pheromone had more adult and larval damage than untreated plots, indicating increased insect activity. This work demonstrated that in principle, populations of S. lineatus can be manipulated with semiochemicals when these arc deployed in a ‘push-pull’ or ‘stimulo-deterrent diversionary’ strategy. Such a strategy, in which insects are diverted from the crop by a feeding deterrent and attracted to discard areas with an attractant pheromone, could be developed for the management of this pest in arable agriculture.
