INSECT LURES

摘要

22 Novel multi-component insect lures comprising (3Z,6Z)-tridecadien -12-olide and 13-methyl-(5Z,8Z)-tetrsdecadien-13-olide together with a fungal volatile selected from the group consisting of 1-octen-3-ol and 3-methylbutanol, wherein the amount of 11-methyl -(3Z,6Z)-dodecadien -11-olide in the composition is substantially zero, and a novel method for production of these pheromones, whereby the cost of active components may be reduced to economically advantageous levels. The lures are particularly effective in attracting saw-toothed grain beetles of group Coleoptera, Cucujidae, particularly species Oryzaephilus surinamensis.
