“…The parasitism capacity of T. atopovirilia, that is, the total number of eggs parasitized (eggs that became dark) by one of Trichogramma species, was higher than that of T. pretiosum for eggs of Spodoptera frugiperda (JE Smith) (Beserra et al, 2005) and of Stenoma catenifer Walsingham (Nava et al, 2007). In general, T. galloi has a higher parasitism capacity than that of T. pretiosum for Diatraea saccharalis (Fabricius) eggs, as these eggs are rarely parasitized by T. pretiosum (Monje, 1995).…”

“…The parasitism capacity and viability of parasitoids is related to the size and nutritional quality of the host eggs (Bai et al, 1992;Cônsoli and Vinson, 2012), host age (Vinson, 2010;Zhang et al, 2014;Song et al, 2015) and physical barriers to oviposition (Beserra et al, 2005). These factors directly affect population maintenance of natural enemies, a key factor for natural or classical biological control (Flint and Driestadt, 1998).…”

“…In the case of S. frugiperda, control has been carried out through release of parasitoids of the genus Trichogramma spp. (Hymenoptera: Trichogrammatidae) (Beserra et al, 2005;Dequech et al, 2013;Figueiredo et al, 2015;Balestrin and Bordin, 2016) that are used in programs of applied biological control since these agents parasitize the egg phase of the pest and impede the emergence of caterpillars and thus does not occur their attack. In Brazil, the natural occurrence of Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) parasitizing eggs of S. frugiperda (Beserra et al, 2002;Dequech et al, 2013;Balestrin and Bordin, 2016) offers good perspectives for its application because, in addition to its ability to act on the target pest, this parasitoid is easily rearing in the laboratory conditions.…”

The possible interference of resistant pest’s populations to insecticides in natural enemies in the action thas not been clarified yet. Thus, this study aimed to evaluate Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) performance on Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) eggs with resistance frequency to the Metaflumizone over six generations of product exposure. Egg cards (2.0 x 7.0 cm) containing eggs from two populations of S. frugiperda, (resistant to Metaflumizone and the other susceptible), were exposed to T. pretiosum females for 24 hours in free-choice and no-choice testing in three generations (G1, G4, and G6). A completely randomized experimental design was used with 25 replications, each consisting of an egg card (experimental unit) containing 20 eggs. The parameters evaluated were: parasitism (%), emergence (%), sex ratio, number of emerged parasitoids per egg and males/females longevity. ANOVA and Tukey test (P≤ 0.05) were applied on the results. Results showed a reduction in parasitism [41.0% (G1) and 28.4% (G4)], egg emergence (17.5%) and parasitoids/egg [16.2 (G4) and 17.2 (G6)] in eggs originating from the population with resistance frequency. Females emerging from G6 populations eggs without exposure to Metaflumizone had greater longevity (3.5 days more) than the resistant population. The sex ratio and male longevity were not affected. The results indicate a reduction in T. pretiosum activity if S. frugiperda populations have some frequency of resistance to Metaflumizone.
