For the vast majority of Lepidopterous pests of field crops, rice and vegetables the most appropriate trapping device is the AgriSense Funnel Trap. Certain smaller moths, primarily Tortricids (tortrix moths and leaf rollers), Gelechids, like pink bolIworm and potato tuber moth and Plutellids, such as diamond back moth are usually caught using the more sensitive Easiset Delta Traps. However, in areas where dust is a problem, funnel traps may be preferable for these smaller species even though they may be somewhat less effective.

Easiset Delta Traps are effective for many Noctuids too, although due to the size of these moths, Funnel Traps are more appropriate particularly when large populations are present and the sticky boards of Delta Traps become rapidly covered. Delta Traps are also appropriate for monitoring the effectiveness of mating disruption treatments against moth pests. Insects are only caught when the treatment loses effect, while the treatment is working no moths are caught.

An economical variant of the Delta Trap is the Trident Trap, which is specifically used for monitoring pink bollworm in cotton. The Trident Trap is a waxed-card delta trap, ready glued on 3 internal sides. For information on trap selection please see Technical Support
