Biological characteristics of Trichogramma maxacalii (Hymenoptera: Trichogrammatidae) on eggs of Anagasta kuehniella (Lepidoptera: Pyralidae)

Abstract: Individuals of two populations of Trichogramma maxacalii (Hymenoptera: Trichogrammatidae) were collected from eggs of Euselasia apisaon (Lepidoptera: Riodinidae), a lepidopteran defoliator of Eucalyptus, in plantations in the states of São Paulo and Minas Gerais, Brazil. This study investigated the sex ratio, number of parasitoids per egg, and longevity of individuals of these two populations of T. maxacalii, when this parasitoid was reared receiving eggs of the factitious host Anagasta kuehniella (Lepidoptera… Show more

“…Food deprived parasitoids will first search for food resources before they search for hosts (Hegazi et al 2000). In addition, sugar feeding influences overall individual flight, foraging behavior (Forsse et al 1992;Pompanon et al 1999;Romeis et al 2005), and longevity (Oliviera et al 2003). Hegazi et al (2000) observed that honeydeprived T. cacoeciae Marchall only attacked one host patch whereas fed females were more likely to move to a second host egg patch.…”

“…O emprego desses microhimenópteros em programas de controle biológico foi viabilizado por Flanders (1930) traça-das-farinhas, especialmente no Brasil (Paron et al 1998;Pratissoli et al 2000;Oliveira et al 2003;Pratissoli et al 2004). Aspectos biológicos de Trichogramma são influenciados diretamente pelas mudanças climáticas, havendo necessidade de estudos para determinar as condições ideais para a sua multiplicação em laboratório e utilização no campo (Calvin et al 1984;Parra 1997;Pratissoli et al 2003).…”
