THE LIFE HISTORY OF TOUMEYELLA PINI (KING) (HOMOPTERA: COCCIDAE) IN LOBLOLLY PINE SEED ORCHARDS IN GEORGIA

Abstract

AbstractThe striped pine scale, Toumeyella pini (King), had three generations per year in south Georgia. Females developed on snoots and males developed on needles of loblolly pine, Pinus taeda L. Generations overlapped and crawlers were most abundant in May, mid-July to early August, and late October to early November. The average fecundity was 1865 crawlers per female. Parasitism averaged ca. 15%, but the predation rate reached 50%. Coccophagus lycimnia Walker (Hymenoptera: Aphelinidae) was the most common parasitoid reared from both males and females. A pyralid larva, Laetitia coccidivora (Comstock), was a frequent predator of females.
