NONATO DE OLIVEIRA, Harley et al. LIFE TABLE OF THE TRICHOGRAMMA EXIGUUM (HYMENOPTERA: TRICHOGRAMMATIDAE). Idesia [online]. 2007, vol.25, n.1, pp.73-76. ISSN 0718-3429.  http://dx.doi.org/10.4067/S0718-34292007000100008.

Trichogramma it is one the most important natural enemies and has been successfully utilized for biological control of several pests world-wide. The objective was to construct a life table of Trichogramma exiguum in different generations, when reared on eggs of Anagasta kuehniella and Sitotroga cerealella. The research was development at 25 ± 1°C, 70 ± 10% relative humidity and 14 hours of photophase and were evaluated the duration of a generation (T), liquid reproductive rate (Ro), infinitesimal rate of increase (rm) and finite rate of increase (λ). The results showed that T. exiguum were more efficient in eggs of A. kuehniella, showing to be these insect the most indicated to establish a massal rearing.
