Abstract

We developed techniques for examining ovarian dynamics of the seedcorn maggot, Delia platura (Meigen), and delineated detailed procedures for ovarian dissections and classifications.A three-class ovarian rating system was devised and physiological ages for each class were determined. The preovipositional period was 36 degree-days (DD) in the field and 100 DD in the laboratory. No ovarian development was observed unlessfemales had been given a protein food source. All females with ovarian development had mated.
