Tabela de Esperança de Vida de Trichogramma pretiosum Riley em Ovos de Trichoplusia ni Hübner em Diferentes Condicionamentos Térmicos

Abstract: O objetivo deste trabalho foi estudar a influência da temperatura sobre parametros demográficos do parasitóide de ovos, Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae), criados em ovos da lagarta falsa-medidera-das-crucíferas, Trichoplusia ni Hübner (Lepidoptera: Noctuidae), em condições de laboratório. Para tal foram confeccionadas cartelas azuis celeste contendo ovos de T. ni que foram oferecidos ao parasitismo de T. pretiosum por 24 horas nas temperaturas de 18, 21, 24, 27, 30 e 33 °C. Após es… Show more

“…For Trichogramma spp., the number of individuals emerged per egg was also counted, since these species characteristically superparasitize eggs of Spodoptera spp. ( Carvalho et al 2012 , Cabezas et al 2013 ). To carry out the statistical analyses, the mean of the 3 days of parasitism was used for each biological parameter.…”
