Infection by the entomogenous fungus, Beauveria brongniartii, of adults of the Yellow Spotted Longicorn Beetle, Psacothea hilaris was examined by dispersing conidia using non-woven fabric sheet containing the fungus. The mortality of adult beetles was 100% when they were reared 50 cm from the sheet for 7 days. When the adult beetles were allowed contact with leaves contaminated by dispersed conidia, the mortality was 30%-40%. Sheets containing the fungus covered with an opaque plate were hung on fig trees to control P. hilaris adults. The mortality of adult beetles collected 10 days after attaching the sheet was 90%, but decreased to 57% after 31 days. More than 10^7 conidia/cm^2 exhibiting infectivity to P. hilaris adults were detected for 55 days after sheet attachment.
