Unlike their fastidious cousins, stink bugs feed on some 300 species of plants, including figs, mulberries, corn, and citrus fruits as well as soybeans, legumes, and weeds. Although they do little damage to the plant itself, they make the fruits and vegetables unmarketable. For this reason, stink bugs pose the most serious threat to the big agriculturalists and macro farm operators. Macro farmers have more invested in their produce, and therefore have more to lose.
