Field and laboratory methods were used to study population growth and feeding damage of Lygus hesperusKnight (a major cotton pest) on isogenic lines of glandless and glanded cotton, Gossypium spp. In no‐choice field cages, a glandless genotype had 2.5 times more L. hesperusand 57% fewer bolls compared to its glanded equivalent. The larger lygus bug population on glandless cotton was attributed to a two‐fold increase in growth rate and survival of nymphs. Thus glandless cotton may require more intensive control of L. hesperusthan normal glanded cotton, to minimize losses in yield and quality. |
