Résumé :

The development of two Trichogramma species, T. cacoeciae and T. evanescens (Hym., Trichogrammatidae), parasitoids of Lobesia botrana (Lep., Tortricidae) have been observed under natural conditions in Antibes-Franc, during the fall and winter seasons, 1990/1991. It is clear that, T. cacoeciae and T. evanescens can stop their development by either quiescence or diapause, in these natural conditions. T. evanescens was more sensitive to low temperatures than T. cacoeciae
