Diaphorina citri(Hemiptera: Psyllidae) Infection and Dissemination of the Entomopathogenic FungusIsaria fumosorosea(Hypocreales: Cordycipitaceae) Under Laboratory Conditions

摘要: ABSTRACT The infectivity and horizontal transfer of Isaria fumosorosea Wize among Diaphorina citri Kuwayama was measured using a detached leaf bioassay in which blastospores were sprayed on citrus sections or yellow plastic tags (artificial attractant surface). Four three one tag placed together Petri dish chamber. One to four the with I. (1.2–1.7×103 blastospores/mm2).
