Abstract:Data on seed yields from cones of slash pines, Pinus elloittii Englem, and loblolly pines, P. taeda L., infested with Dioryctria amatella(Hulst) larvae were obtained from 2 seed orchards in Mississippi. Infested cones of slash pine yielded an average of 4.96 seeds per cone as compared with an average yield of 37.76 seeds per non- infested cone. Infested loblolly cones yielded an a\'el'- age of 11.80 seeds per cone and noninfested cones yielded an average of 54.31 seeds per cone. The differences in yields were statistically significant at the 0.01% level of probability.
