Abstract: This work evaluated the ovicidal effect of the nematophagous fungi Monacrosporium sinense (SF53), Monacrosporium thaumasium (NF34) and Pochonia chlamydosporia (VC1) on Taenia taeniaeformis eggs in laboratory conditions. T. taeniaeformis eggs were plated on 2% water-agar with the grown isolates and control without fungus and examined at seven and fourteen days post-inoculation. At the end of the experiment, P. chlamydosporia showed ovicidal activity (P \ 0.01) on T. taeniaeformis eggs unlike the other two speci… Show more

“…This is an important finding, since P. chlamydosporia produces large amounts of chlamydospores, resistant survival structures that enable the passage of this fungus through the gastrointestinal tract of domestic animals (Araú jo et al, 2004;Lopes et al, 2007). Using a different P. chlamydosporia isolate (VC1) against T. taeniaeformis eggs, Braga et al (2009) reported results of 32.2% and 54.0% for type 3 effect at 7 and 14 days, respectively. In this study, the isolate VC4 showed 49.25% and 53.4% of type 3 effect at the same intervals.…”

“…The penetration mechanism of ovicidal fungi on parasitized eggs is still not completely clarified, as the fungi show differences in their ovicidal activity (Braga et al 2008c). However, several authors admit that enzymatic activity is a major component in the attack and egg penetration, thus, these fungi could be used in biological control (Lysek and Sterba 1991).…”

“…This fungus is widely distributed and has been successfully used in laboratory conditions for the biological control of gastrointestinal nematode parasites eggs of root-knot nematodes (Kerry and Hidalgo 2004), Ascaris suum (Araújo et al 2008), A. lumbricoides (Braga et al 2007) and Taenia taeniaeformis (Braga et al 2008c). The action of this fungus is based on appressorial formation developed from undifferentiated hyphae, which allows the colonization of the egg surface and penetration through both mechanical and enzymatic actions (Lysek and Sterba 1991).…”

“…O mecanismo de penetração dos fungos ovicidas nos ovos parasitados ainda não está totalmente elucidado, e por isso existem diferenças na sua atividade ovicida (Braga e cols 14 . Entretanto, vários autores admitem que a atividade enzimática seja um dos principais componentes no processo de ataque e penetração através dos ovos e por isso estes fungos poderiam ser utilizados no controle biológico 15 .…”
