Lesser Cornstalk Borer Numbers High in Dry Summers

Lesser cornstalk borers (LCB) are soil pests that like dry weather, making them a classic indicator of drought. LCBs prefer various legumes, including peanuts and soybeans. In peanuts, LCB damage can cause crop contamination from webbing and direct yield loss if unchecked.

Four to five generations of LCBs may occur each year, with the worse cases being in areas with sandy soils. Moth numbers can often be high in central and southeast and Alabama. Currently, moth numbers exceed 3,000 from statewide traps (doubled activity since June), suggesting the scattered showers the state has received are not enough.
