Larvae of a soybean stem borer, Dectes texanus texanus LeConte, cause economic loss in soybeans by girdling the stem prior to harvest. Chemical control is complicated because larvae spend ca. 10 months inside the stem or in stubble. Insecticide granules and sprays were ineffective against larvae. Multiple insecticide applications would be required for adult control. Cultural control by winter burial of stems with deep plowing or row bedding methods proved effective in reducing larval survival and adult emergence. Burial of stems at a depth of 2 in. was sufficient to decrease larval survival and adult emergence.
