Abstract

The effect of temperature and relative humidity on mating and commencement of oviposition in Plodia interpunctella (Hubner) was studied in the laboratory. Mating was most successful at 20 and 30°C and was less so at temperatures of 15 and 35°C. Increased relative humidity appeared to have favoured mating at higher temperatures investigated which were 30 and 35°C.

The onset time for mating was higher at 30 and 35°C than at 15 and 20°C. Mating started earlier at the lower temperatures than at higher temperatures. The mean duration of mating was higher at 15 and 20°C than at 30 and 35°C at which high relative humidity favoured increase in mating time.

At 20 and 30°C oviposition started within the first 2 days of mating whereas at 15°C oviposition started about 8 days after mating. At 35°C oviposition commenced within 4 days. Low relative humidity caused early commencement of oviposition at 15 and 35°C.

Résumé

L'effet de la température et l'humidité relatives sur l'accouplement et le commencement de l'oviparité sur Plodia interpunctella était étudié au laboratoire. L'accouplement avait réussi plus à 20 et à 30°C qu' à 15 et à 35°C. L'augmentatran de l'humidité retative paraisait avoir favorisé l'accouplement aux températures plus hautes de la recherche. C'est-à-dire à 30 et à 35°C. Le nombre du temps d'oviparité au debut de l'accouplement était plus à 30 et à 35°C qu'à 15 et à 20°C. L'accouplement avait commencé plus tôt aux températures plus bases.

La durée moyenne d'accouplement était plus haute à 15 et à 20°C qu'à 30 et à 35°C. C'était aux les deux dernièves températures que l'humidité rélative a favorisé des hausement du temps d'accouplement.

A 20 et à 30°C, l'oviparité avait commencé dans les deux jours précedents de l'accouplement tandis qu'à 15°C, l'oviparité avait commencé presque huit jours après l'accouplement. A 35°C, l'oviparité avait commencé dans quatre jours. L'humidité relative base avait produit l'effet d'une oviparité tôt à 15 ot à 35°C.
