Resumen:
Previous research concerning the Entomophthorales has demonstrated their capabilities as biological control agents. To use them widely and at industrial levels, studies to demonstrate their innocuity in animals must be made. The present study concerns the intraperitoneal and subcutaneous inoculation of 274 animals (mice and guinea pigs) with Erynia neoaphidis Remaudière & Hennebert and Conidiobolus major (Thaxter) Remaudière & Keller, fungi pathogenic for the spittlebug [Aeneolamia postica (Walk) and Prosapia simulans (Walk)] in Mexico. The alterations found were macroscopic tissue lesions consisting of nodules, abscesses and adhesions in the liver, spleen, kidneys and intraperitoneal cavity. No fungi could be recovered from organs at any time and only lysed filaments surrounded by polymorphonuclear cells could be seen at day 8 post-inoculation. The histopathological findings showed no important pathological alterations. These results suggest the innocuity of Erynia neoaphidis Remaudière & Hennebert and Conidiobolus mamor (Thaxter) Remaudière & Keller in mice and guinea pigs. © 1986 Lavoisier Abonnements.
