Resistance to Seed Feeding by Southern Green Stink Bug, Nezara viridula (Linnaeus), in Soybean, Glycine max (L.) Merrill Academic Article uri icon

abstract

  • Southern green stink bug, Nezara viridula (Linnnaeus), feeds on developing seeds of soybean, Glycine max (L.) Merrill, and is an important pest of the crop in the southern US. Sixteen soybean lines were evaluated for resistance by caging adult southern green stink bugs on pods in an insectary. The resistant standard, IAC-100, had the fewest feeding punctures per seed which was not significantly different from the number for genotypes V00-0742, V00-0842, or V99-1685. When exposed to southern green stink bug, the seed weight for IAC-100 was not significantly different from that of the genotypes PI 558040, V00-0870, or PI 588053A. The percentage of seed weight loss for IAC-100 was not significantly different from that of seed weight loss of PI 558040 or V00-0870 when exposed to feeding by southern green stink bug. The genotypes IAC-100, V00-0742, V00-0842, and V99-1685 are resistant to feeding by southern green stink bug based upon a reduction in feeding punctures, while genotypes IAC-100, PI 558040, and V00-0870 may provide a source of genetic traits for resistance by minimizing seed weight loss caused by feeding by southern green stink bug.
