Abstract

Disclosed is a method for disrupting reproductive performance of an adult arthropod pest, comprising contacting the adult arthropod pest or its environment with a sub-lethal, reproduction-disruptive amount of a carboxamide arthropodicide, its N-oxide, or a salt thereof.

Description

technical field [0001] The present invention relates to a method of disrupting the reproductive capacity of arthropod pests comprising exposing the arthropod pests or their environment to a sublethal, reproduction disrupting amount of a carboxamide arthropodicide, an N-oxide or a salt thereof. Background technique [0002] The control of arthropod pests is very important to achieve high yield of crops. Control of arthropod pests is also important in forestry, greenhouse crops, ornamental plants, nursery crops, stored food and fiber products, livestock, household goods, turf, wood products, and public and animal health. Arthropod damage to growing and stored crops can result in a significant reduction in productivity and thus increased costs to consumers. [0003] Methods of controlling arthropods generally require the application of arthropodicides to the pest or its environment in lethal amounts. Repeated exposure to the same arthropodicide may lead to selection of arthro...
