Abstract: Solid particle-form, polymerizable or cross-linkable, multi-functional polymeric material containing blocked isocyanate groups wherein the blocked isocyanate groups making up said polymeric material comprise only a portion of the total isocyanate groups to produce said polymeric material, such as extrudable, thermosettable powdered blocked polyurethane (PBP) has been prepared. This material is useful per se for the manufacture of articles and may be added in combination with other materials, such as thermoplastic resin, e.g. polyethylene, polyvinyl cloride, for improving the usefulness, versatility and physical and/or chemical properties thereof. The polymeric material, such as PBP, is useful as a coating on metal and non-metallic surfaces, e.g. glass or fibrous surfaces, either as a protective coating or for the purpose of laminating such surfaces to another surface.

Abstract: The sex pheromone of the pink bollworm (Pectinophora gossypiella) is an approximate 1:1 mixture of (Z,Z)- and (Z,E)-7,11-hexadecadienyl acetate; this sex pheromone, the above-identified mixture of isomers, is known as Gossyplure. A component of Gossyplure, (Z,E)-7,11-hexadecadienyl acetate, is the sex pheromone of the Angoumois grain moth (Sitotroga cerealella) and is known as Angoulure. An isomeric component of Gossyplure, the Z,Z isomer, elicits no response from the male Angoumois grain moth and it appears that the relatively large amount of the Z,Z isomer in Gossyplure interferes with the Z,E isomer such that Gossyplure cannot be used as a substitute for Angoulure.

Abstract: A boll weevil trap comprises a support means, preferably colored or painted daylight fluorescent yellow, an open-ended hollow guiding means releaseably mounted on the upper end of said support means, perforated hollow trapping means detachably affixed at its open lower end to about the open upper end of said guiding means, said guiding means being adapted at about its open lower end to be releaseably affixed to the upper end of said support means to provide an annular space between the outside of said support means and the inside of the open lower end of said guiding means, the opening provided at the upper end of said guiding means being substantially smaller than the opening provided at the lower end of said guiding means, the opening at the upper end of said guiding means extending within the interior space of said trapping means.
