What scouting indication exists for Brown Marmorated Stink Bug?

The correct indication for scouting Brown Marmorated Stink Bug (BMSB) is the presence of adults. This is essential for pest management because adult bugs are typically more mobile and widespread than nymphs, making their presence a strong indicator of a potential infestation in an area. When scouting for BMSB, finding adult insects signals that they may be surveying crops for feeding or laying eggs.

The presence of adults can also provide insight into the life cycle stages and the timing of management strategies that might be necessary. Understanding where adults are located can help determine the risk to certain crops and guide the timing of control measures effectively.

Other factors like high humidity, while they may have an impact on the behavior of BMSB, do not serve as a direct indicator for their presence and activity. Ignoring wild hosts isn’t a scouting indicator either, as wild hosts can sometimes harbor BMSB populations that may move to cultivated crops. Seed damage, while a potential result of feeding by BMSB, is a consequence of their feeding rather than an indication of their presence during scouting activities.
