Conelet Abortion and Seed Damage of Shortleaf and Loblolly Pines by a Seedbug, Leptoglossus corculus
Abstract:Feeding by a seedbug, Leptoglossus corculus (Say), on shortleaf and loblolly pines caused conelet abortion and drastically reduced seed yields in field-cage experiments. Conelets protected for the 1971 growing season or exposed only to adult bugs did not abort. L. corculus feeding, particularly early in the season, reduced seed yield and quality when artificially or naturally infested cone clusters were compared with clusters protected throughout the season. Loblolly pine cones protected only during the second year of development yielded 2 1/2 times as many filled seed as did cones exposed to natural bug populations, and almost 6 times as many full seed as did cones exposed to 2 weeks of bug feeding in the early treatment. Caged shortleaf pine cones yielded 12 times as many full seed as did uncaged cones. Forest Sci. 20:165-170.
