“…Thus, without the aid of wind and rain, fungus‐infected cadavers at the higher parts may more or less disperse the conidia. Entomophaga aulicae has a relatively wide host range, comprising various lepidopteran species (Aoki 1981, 1998, 2003; Goto & Tsutsui 1989; Hicks & Watt 2000), and may infect other lepidopteran species in the study area by conidia discharged from the cadavers of C. nivea .…”

“…Weseloh & Andreadis 1992; Hajek 1997; Hicks & Watt 2000). Some fungi and viruses alter behavior of host insects, causing them to climb up vegetation and to die at a high site (Aoki 1998; Goto & Tsutsui 1989; Maitland 1994; Goulson 1997). These behavioral alterations have been interpreted to be adaptive for the pathogens, aiding dispersion of spores and viruses (Horton & Moore 1993; Maitland 1994; Goulson 1997).…”

We observed epizootics and behavioral alteration in the arctiid caterpillar Chionarctia nivea after infection by an entomopathogenic fungus, Entomophaga aulicae , in April at a riverbank in Kyoto Prefecture, central Japan. The density of arctiid cadavers infected with E. aulicae was 1.31 individuals/m 2 . The critically ill caterpillars crawled up the dead stems of grasses and herbs such as the common reed Phragmites communis and the Japanese mugwort Artemisia indica var. maximowiczii to die at and near the highest parts of the stems, while the healthy larvae usually wandered on the ground and fed on the leaves of small herbs. This behavioral difference could be caused by infection with E. aulicae to enhance dispersal of conidia by active discharge in Entomophthorales with the aid of wind and rainfall.
