Appl. No.:

6/610949

Inventors:

Wendell E. Burkholder - Madison WI

Assignee:

The United States of America as represented by the Secretary of
Agriculture - Washington DC
Zoecon Corporation - Palo Alto CA

International Classification:

A01M 100

US Classification:

43107

Abstract:

A poisonless trap for monitoring and control of insects, especially stored-product pests of the order Coleoptera, comprising a housing device, a pitfall chamber within the housing device, oil within the pitfall chamber, and an attractant. Insects lured into the pitfall by the attractant die by suffocation in the oil.

International Classification:

G01N 33543

US Classification:

435 721

Abstract:

The present invention involves approaches to the detection of insect contamination of foodstuffs such as grain, for example. These approaches involve the detection of biological substances characteristic of insects. One such approach is an assay for the insect exoskeleton material, chitin. This test is particularly suited to the detection of live or dead specimens of the adult or egg stages of insects and for insect parts. Another type of assay uses an immunological approach to the detection and quantitation of an insect-specific protein such as the insect muscle protein, myosin or components thereof, for example. This type of test is well suited for detecting all stages of insect development from egg to adult, whether live or dead. It should also provide an assay system that correlates well to the current insect fragment assay.

International Classification:

A01N 2500

US Classification:

424 84

Abstract:

The compound 5-hydroxy-4-methyl-3-heptanone (sitophilure) having the structural formula ##STR1## has been identified as an aggregation pheromone for both males and females of grain weevils belonging to the genus Sitophilus. The compound and compositions containing the same are useful tools for the monitoring and control of these major agricultural pests of stored grain.

International Classification:

A01M 100

US Classification:

43107

Abstract:

A contact and odor responsive device for trapping khapra beetles and their larvae in which fibrous paper or fabric strips are constructed to provide contact allowing forms containing pheromone attraction means, food attractive means and lethal means for destroying the beetles and a method of using said traps to detect and destroy the beetles and their larvae.
