The most economically significant species is D. texanus, commonly known as the Dectes stem borer or soybean stem borer, which has become an important agricultural pest of soybean and sunflower crops in the central and eastern United States. Larvae tunnel into plant stems and girdle the base before overwintering, causing lodging and yield losses. D. sayi is also associated with soybean and sunflower but prefers common ragweed (Ambrosia artemisiifolia) as a primary host.
Dectes texanus
Dectes stem borer, Texas prick, soybean stem borer
Dectes texanus is a native North American longhorn beetle (Cerambycidae: Lamiinae) that has emerged as a significant agricultural pest of soybeans and sunflowers in the Midwestern and Great Plains regions of the United States. Adults are characterized by antennae longer than their bodies and a pale gray coloration. Larvae tunnel inside plant stems from July through October, then girdle the stem base internally before overwintering, causing pre-harvest lodging and yield losses. The species has expanded its range and pest status dramatically since the 1980s, correlating with increased soybean acreage and adoption of no-till farming practices. Originally associated with wild hosts including ragweed and cocklebur, it colonized cultivated soybeans approximately 50 years ago.
