Abstract

The effects of temperature on the life history of Spilostethus pandurus (Scopoli) were examined by determining the different developmental and reproductive parameters with respect to days of hatching, oviposition, and adult emergence of insects reared in field cages at Giza, Egypt. Hatching, oviposition, and adult emergence continued all year round; the average daily temperature in the coldest month (January) seemed to be above developmental thresholds for different stages. This lygaeid completed six overlapping generations in 1 year. The basic population parameters, i.e. net reproductive rate (R0), gross reproductive rate (GRR), instantaneous rate of natural increase (r), finite rate of natural increase (λ), and mean generation time (T) exhibited a more or less cyclic pattern in successive generations. The highest value of r (rmax) was considered as the intrinsic rate of natural increase of this species.

Résumé

Les effets de la température sur le cycle vital de Spilostethus pandurus (Scopoli) ont été examinés en déterminant les différents paramètres de croissance et de reproduction en rapport avec les dates d'éclosion, la ponte d'oeufs et l'émergence des adultes sur des insectes élevés dans des cages de terrain à Giza, Egypte. L'éclosion, la ponte des oeufs et l'émergence des adultes se sont poursuivies tout au long de l'année; la température journalière moyenne du mois le plus froid (janvier) a semblé être au dessus des seuils de croissance de différents stades. Ce lygaede a réalisé en une année six générations se chevauchant entre elles. Les paramètres fondamentaux de la population, c.a.d. le taux net de reproduction (R0), le taux brut de reproduction (GRR), le taux instantané de croissance naturelle (r), le taux fini de croissance naturelle (λ) et le temps moyen par génération (T) ont manifésté un caractère plus ou moins cyclique au cours des générations successives. La plus grande valeur de r (rmax) a été retenue comme taux intrinsèque de croissance naturelle de cette espèce.
