<b>Biological parameters of three <i>Trichogramma pretiosum</i> strains (Riley, 1879) (Hymenoptera: Trichogrammatidae) on eggs <i>Helicoverpa armigera</i> (Hübner, 1805) (Lepidoptera: Noctuidae)

Abstract: ABSTRACT. This project has an objective to study the biological parameters of Trichogramma pretiosum on eggs of H. armigera. The three strains of T. pretiosum were evaluated: TM, TMC and TLEM, from different places. The experimental establishing was completely randomizing with twenty repeats per treatment, being used by a female parasitoid by repetition and later on they were offered 20 H. armigera eggs. The experiment was kept on BOD cameras to 25 ± 2° C, UR 60 ± 10% and photo phase of 14 hours. Evaluating th… Show more

“…There are no insecticides registered for H. armigera in Brazil (Vivan, Torres, & Fernandes, 2017). However, strategies of biological control have been reported in Brazil as promising options for control of the cotton bollworm, such as: strains of virus HzSNPV (Ardisson-Araújo, Sosa-Gómez, Melo, Báo, & Ribeiro, 2015), Cry toxins and entomopathogenic fungi (Metarhizium anisopliae, Metarhizium rileyi and Nomuraea rileyi) (Costa et al, 2015;Vivan, Torres, & Fernandes, 2017), larval parasitoid (Guerra, Guerra, Ribas, Gonçalves, & Mastrangelo, 2014), and egg parasitoid (Carvalho et al, 2017;Zuim, Rodrigues, Pratissoli, & Torres, 2017).…”
