Abstract The seedcorn maggot, Delia platura (Meigen; Diptera: Anthomyiidae), is a polyphagous pest that feeds on decaying organic matter, seeds, and seedlings of several crops, including corn ( Zea mays L.; Poaceae). In corn and soybeans, D . platura is a sporadic pest. To make recommendations as to which sticky trap color is more effective at trapping D. platura , we sampled 52 corn fields in four regions across New York State with blue and yellow sticky cards. More adults were caught with blue (77.6 %) than yellow cards (22.4 %). The same pattern was observed when all individuals were combined and separated by females and males. The higher captures with blue sticky cards were consistent across space and time, indicating the effectiveness of trapping adults and monitoring them at a regional scale.
