BIOSIS COPYRIGHT: BIOL ABS. The impact of delaying soybean (Glycine max (L.) Merr.) planting following the incorporation of a living, green cover crop and using various insecticide management practices on seedcorn maggot (Delia platura (Meigen)) populations was evaluated. Phorate soil insecticide in a 15.8 cm band and Agrox D-L Plus seed treatment (a mixture of diazinon (0.33% w/w), lindane (15.0% w/w), and captan (14.67% w/w)) were applied at planting immediately after, and 1.5 or 3 weeks after, cover crop incorporation that occurred in early May. Seedcorn maggots were sampled with adult emergence traps, and subsequent soybean injury to plumules were estimated. The number of days following tillage that soybean was planted had little effect on maggot numbers collected, but injury was lowest on soybean planted 3.5 weeks after incorporation of the cover crop. Thermal unit accumulations indicated that seedcorn maggot oviposition occurred at the time of tillage, and that the majority of insects were
