Which pest is more commonly a problem during a cold, wet spring?

Seedcorn maggot is more commonly a problem during a cold, wet spring due to its biology and life cycle. These pests thrive in conditions that are less favorable for many crops. Cold, wet soils create an environment that delays seed germination and root development, making seeds and young seedlings more vulnerable to damage.

The seedcorn maggot lays its eggs in or near germinating seeds, particularly in moist soil where decaying organic matter is present, which serves as an ideal food source for the larvae once they hatch. The presence of excessive moisture can lead to slower seed germination while also prolonging the emergence period, thereby increasing the likelihood of crop damage by these pests before the plants become established and resilient.

In contrast, other pests listed may not have the same peak activity or might be adversely affected by wet and cold conditions. For example, wireworms typically favor drier conditions since they are soil-dwelling and can be more damaging during warmer, dryer springs. Flea beetles and stalk borers may be less active or present in lower numbers during colder conditions when crops are not growing as robustly. Thus, the seedcorn maggot's life cycle aligns closely with cold, wet springs, making it the more problematic pest during these conditions
