Abstract
Curculio caryae larvae exposed to Beauveria bassiana or Metarhizium anisopliae were held in soil cages for 14 months. After weevil larvae were colonized by B. bassiana, hyphae from the weevil cadavers spread through the surrounding soil and formed colonies up to 8.55 cm in diameter (soil volume, 327.26 cm 3 ). M. anisopliae colonies were restricted to larval cadavers and to the inside of larval soil cells. Adjacent, untreated weevil larvae were sometimes infected and killed by B. bassiana that spread through the soil. B. bassiana colonies reached maximum diameter and threatened adjacent weevil larvae 90 to 120 days after primary larvae were infected.This publication has 0 references indexed in Scilit:
