Two prototype trap designs and four other trap designs currently on the market were evaluated for capture of Japanese beetles, Popillia japonica Newman. The standard Japanese beetle trap manufactured by Trece (Palo Alto, CA) and a prototype trap captured consistently more beetles than other trap designs tested. Traps that used a bag for collection of beetles were not as effective because beetles were able to escape through the holes made for drainage. The new trap design allows traps to be transported more easily and stored in a smaller area because of the collapsible design. This is a significant improvement for states that use thousands of traps for monitoring Japanese beetles.
Journal of Economic Entomology is published bimonthly in February, April, June, August, October, and December. The journal publishes articles on the economic significance of insects and is divided into the following sections: apiculture & social insects; arthropods in relation to plant disease; forum; insecticide resistance and resistance management; ecotoxicology; biological and microbial control; ecology and behavior; sampling and biostatistics; household and structural insects; medical entomology; molecular entomology; veterinary entomology; forest entomology; horticultural entomology; field and forage crops, and small grains; stored-product; commodity treatment and quarantine entomology; and plant resistance. In addition to research papers, Journal of Economic Entomology publishes Letters to the Editor, interpretive articles in a Forum section, Short Communications, Rapid Communications, and Book Reviews.
