Table 4.
Active Trichogramma females (%) (=parasitizing at least one T. absoluta or one S. cerealella egg in 2 h) during the host preference test. Five eggs of the target host T. absoluta and five eggs of the rearing host S. cerealella were simultaneously offered to each Trichogramma female. Arithmetic means ± SE are calculated from three trials per strain, each with 10 females.
