DALVI, Leandro Pin et al. Selectivity of Lecanicillium lecanii (Zimm.) Zare & W. Gams (class-form: Hyphomycetes) to the parasitoid Trichogramma atopovirilia Oatman & Platner, 1983 (Hymenoptera: Trichogrammatidae). Ciênc. agrotec. [online]. 2007, vol.31, n.5, pp. 1392-1395.

The present work studied the biological characteristics of Trichogramma atopovirilia in eggs of Spodoptera frugiperda under influence of the fungus Lecanicillium lecanii, with the aim of verifing in laboratory if this entomopathogenic fungus is selective to the parasitoid. The studies were carried out in the entomology sector of Nucleus of Scientific & Technological Development in Phytossanitary Management (NUDEMAFI). The indicatives of selectivity adapted used were: number of parasited eggs, emergency percentage (viability), number of individuals for egg, sex ratio and longevity of the females that parasited. None of these parameters were affected by the fungus, leading to the conclusion that the same is selective to T. atopovirilia, possibiliting the simultaneous utilization of both agents of biological control into the Integrated Management of Pests.
