Abstract

Preliminary investigations have shown the presence of pathogenic fungi in natural populations of the cassava green spider mites. Among others, Entomopthora sp. and Hirsutella sp. were isolated from dead mites sampled from the field. Laboratory bioassays have given mite mortality of up to 60%, indicating the possibility of utilizing some of these pathogens in mite control. Tests with Beauveria bassiana, isolated from lepidopteran pests, have also shown that the mite is susceptible to this fungus.

Résumé

Des études préliminaires ont montré, la présence de champignons pathogènes, dans des populations naturelles d'acariens (verts) du manioc. Entre autres, Entomopthora sp. et Hirsutella sp. ont été isolés des échantillons d'acariens (verts) morts prélevés sur le terrain. Des études en laboratoire ont montré un taux de mortalité allant jusqu'à 60%; ce qui suggère la possibilité de l'utilisation de certains champignons pathogènes, dans le contrôle d'acariens. Des tests réalisés avec Beauverua bassiana isolé des Lépidoptères ravageurs ont également montré que l'acarien (vert) est sensible à ce champignon.
