This invention relates to novel methods and compositions for attracting and controlling the Douglas-fir tussock moth (DFTM). More specifically, this invention pertains to the use of novel pheromone combinations and methods to attract and control DFTM which is a major defoliator of Douglas-fir and other true firs. A composition for manipulating the behaviour of Douglas-fir tussock moths comprising: (a) Z6-heneicosen-11-one (Z6); and (b) one or more compounds from the group consisting of: (Z)6,(E)8-heneicosadien-11-one; (Z)6, (E) 9-heneicosadien-11-one; and (Z)6,(Z)9-heneicosadien-11-one.

Method and composition of chemicals for attracting and controlling the

This invention relates to a composition and procedure for manipulating the behaviour of nun moth, Lymantria monacha (L.) and gypsy moth, Lymantria dispar (L.). More particularly, this invention relates to the preparation and use of chiral and racemic disparlure, chiral or racemic cis-7,8-epoxy-octadecane, 2-methyl-Z7-octadecene and Z7-octadene for manipulating the behaviour of nun moth and gypsy moth. A composition of chemicals for manipulating the behavior of nun moth and/or gypsy moth, said composition comprising two or more chemicals selected from the group consisting of: (a) 2-methyl-7R,8S-epoxy-octadecane (RS-disparlure); (b) 2-methyl-7S,8R-epoxy-octadecane (SR-disparlure); (c) 7R,8S-epoxy-octadecane; (d) 7S,8R-epoxy-octadecane; (e) 2-methyl-Z7-octadecene; and (f) Z7-octadecene.

A novel combination of five queen-produced mandibular gland substances which can be used for controlling worker retinue formation around or in place of a honey bee queen Apis mellifera L. is disclosed. The composition comprises: 9-keto-2(E)-decenoic acid, R-(-)- and S-(+)-9-hydroxy-2(E)-decenoic acid, methyl p-hydroxybenzoate, and 4-hydroxy-3-methoxyphenylethanol. Each component more or less is generally weakly active alone, but the blend of five compounds in a ratio corresponding to their occurrence in gland extracts imparts activity equivalent to queen mandibular extract at a level as low as 10.sup.-7 of that present in a queen. This blend of compounds initiates the retinue response, which includes the licking and antennating behaviour that signals the presence of a dominant reproductive queen, and thereby establishes and stabilizes the social fabric of the colony.
