Abstract

Egg parasitoids of the genus Trichogramma are used worldwide as biological control agents againstlepidopterous pests ofseveral crops.The intrinsic rate of naturalincrease (rm) and other biological parameters have been very useful in assessing parasitoids. We used life and fertility tables to estimate several population parameters of a local population of the parasitoid Trichogramma pretiosum and to explore its potential value as a biological control agent ofthe velvetbean caterpillar Anticarsia gemmatalis. All studies were performed at 25 ± 1oC, 50-70% RH and a photoperiod of 14:10 (L:D). The following results were obtained: mean adult female longevity: 6.53 d; survivorship (1x 50%) of adult females: 6 d; maximum mx : 20 / / d; r m : 0.41; R0 : 41.48 / ; T: 8.99 d. These results suggest that T. pretiosum has a great potential to be used for supression of the velvetbean caterpillar in soybean crops in Argentina.
