Bean leaf beetle abundance increased with the increase of soybean production in the 20th century, but their spread northward was prevented by the inhospitality of northern climates. [3] The availability of soybean is the primary constraint for the beetles, so the beetles can’t live in an area that doesn’t have soybeans. [3]
