“…The mean number of eggs laid per nondiapaused female was 47% greater than that from diapaused females (1 199 and 804, respectively). These results generally agree with those reported by Proshold & North (1978) for tobacco budworm, Heliothis virescens; however, we determined only successful mating and oviposition, but not the presence of eupyrene sperm.…”

The effect of parental age at oviposition on the offspring of diapaused and non‐diapaused females of Heliothis zea (Boddie) (Lepidoptera: Noctuidae) was examined under laboratory conditions. Diapause was induced in the laboratory by reducing day lengths and temperatures. The number of eggs per female, duration of the egg stage, percent hatch, duration of the larval stage, percent pupation and four‐day pupal weights of progeny from diapaused and non‐diapaused adults were determined. Significantly reduced egg production and increased duration of egg and larval stages occurred in offspring of diapaused females, but no effect on hatching and pupation percentages and pupal weights were observed. The possible effects of these differences on reproductive potential and length of generation are discussed. RÉSUMÉ Influence de l'age des parents sur la descendance des femelles d'Heliothis zea diapausantes ou non Nous avons examiné au laboratoire l'influence de l'age des parents au moment de la ponte sur la descendance des femelles d'Heliothis zea Boddie diapausantes ou non. La réduction de la longueur du jour et de la température avait induit la diapause au laboratoire. L'étude a porté sur le nombre d'oeufs par femelle, la durée de l'incubation des oeufs, le taux d'éclosion, la durée du développement larvaire, le taux de nymphose et le poids des chrysalides de 4 jours chez les descendants d'adultes diapausantes ou non. Chez les descendants des femelles diapausantes, la production d'oeufs est significativement réduite; de měme, l'incubation des oeufs et le développement larvaire sont significativement prolongés; mais on n'a observé aucun effet tant sur les taux d'éclosion et de nymphose que sur le poids des chrysalides. La discussion porte sur les influences envisageables de des différences dans le potentiel reproducteur et la durée des générations.
