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 (r_m) 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.
