Fecundity of the Lesser Cornstalk Borer, Elasmopalpus lignosellus, from Florunner and Spanhoma Peanut Cultivars¹

Pupal weights and reproductive rates were compared over a 3 year period in females of the lesser cornstalk borer, Elasmopalpus lignosellus (Zeller), from Florunner and Spanhoma peanuts. Weights of pupae from the two cultivars were quite similar. Egg production of moths emerging from pupae collected in Florunner (mean = 297/female) was significantly lower (p ≤ 0.05) than in Spanhoma peanuts (mean = 341/female). In both groups, fertility of eggs averaged ca. 94%.
