Description

Compositions, methods and devices for controlling and monitoring insects Technical Field The present invention relates to devices, compositions and methods for insect control, and more particularly, to multicomponent compositions for use in combination with an apparatus for releasing the composition, and to devices employing the compositions for attracting, capturing and/or monitoring insects, more particularly, beetles of the tail-biting midge (Carpophilus truncatus). Background The tail beetles are the main pests of almonds and cause serious damage to the developing nucleolus. Current "attracting and killing" strategies for controlling such pests rely on baits consisting of (i) beetle aggregation pheromones (produced by adult male loempe beetles that attack the stone fruit) and (ii) a microbial source synthetic food attractant. Recently, the tail biting armor has also been identified as pest to other nuts including walnuts and pistachios. As early as the 90 s of the 20 th century, pheromones and analogues thereof have been synthesized and discovered for various species of the genus uropus (Carpophilus), however, the uropus lutescens have not been fully studied (Bartelt et al 1990,1992;Bartelt 2010). In addition, existing baits developed to control beetles of the genus Barbary beetles attack stone fruits have poor effects on the tail-biting Barbary beetles. Common problems in developing beetle control strategies include trap type, trap arrangement, food-related odor type used by the trap, pheromone and formulation, and bait/attractant duration, in some cases, the release rate of some key attractants drops within 1 day after the bait is deployed in the field. Furthermore, targeting to specific beetle species is problematic, as the general compositions fail to achieve the required specificity and exhibit reduced efficacy in crop protection (Bartelt, 2010). Accordingly, a need exists to overcome or at least alleviate one or more of the difficulties and deficiencies associated with the prior art. Disclosure of Invention In one aspect, the invention provides a composition for attracting beetles of the class of tail-biting midge beetles (Carpophilus truncatus), the composition comprising 3,5, 7-trimethyl-2, 4,6, 8-undecamene or a geometric isomer thereof and one or more C 6-C16 aldehydes.
