Abstract
The developmental history, longevity and fecundity ofPteroptrix smithi (Compere) are described and discussed. Both sexes develop as primary parasites ofChrysomphalus aonidum (L.). Developmental duration at 26°C averages 25 days and the average fecundity at this temperature is 26.5 eggs for unmated and 21.4 eggs for mated females. Under laboratory conditions 50–80% of the eggs are laid during the first few days of adult life. Longevity of females ranges from a maximum of 44 days at 20°C to a minimum of 15 days at 32°C. Male longevity does not differ significantly.
Résumé
Les deux sexes sont parasites primaires de la CochenilleChrysomphalus aonidum L. La durée du développement à 26°C est en moyenne de 25 jours et la fécondité moyenne à cette température est de 26,5 œufs chez les femelles vierges et 21,4 œufs chez les femelles accouplées. Au laboratoire 50 à 80% des œufs sont déposés au cours des tout premiers jours de la vie imaginale. La longévíté des femelles varie de 44 jours à 20°C à 15 jours à 32°C, celle des mâles n'est pas significativement différente.
