This chapter provides an overview of insect trapping and interpretation of trap captures for stored-product protection in bulk grain, food processing, and retail environments. The use of traps for detection, monitoring, and population estimation requires considerable knowledge of insect biology and appropriate trap use. Trap use is essential for development of meaningful integrated pest managem...

Onion maggot, Delia antiqua, larvae are subterranean pests with limited mobility, that directly feed on bulbs of Allium sp. and render them completely unmarketable. Modeling the spa...
