摘要

从柑桔黄龙病的传播媒介柑桔蚜(半翅目:灰蚜科)中分离到2株球孢白僵菌(Balsamo-Crivelli)和1株烟孢白僵菌(Isaria fummosorosea Wize)。研究了分离菌株对柑桔2种蚜蝇(半翅目:木虱科)和柑桔褐蚜(Kirkaldy)的杀伤能力及温度对其生长的影响。所有三种分离株的感染都导致柑橘D. citri的高死亡率。在Cacopsylla spp.和T. citricida中，一些分离株的死亡率一致，但不同分离株的死亡率不同。3株分离菌株在20 ~ 30℃(酸度:155)时菌丝生长旺盛，2株球孢白僵菌在25℃(酸度:155)时生长良好，1株烟孢白僵菌在25 ~ 30℃(酸度:155)时生长良好，说明菌株间的最佳生长温度存在差异。

Pathogenicity and Growth Temperature of Three Isolates of Entomopathogenic Fungi Isolated from the Asian Citrus Psyllid, Diaphorina citri（Hemiptera: Liviidae）, Found in Amami and Okinawa, Japan

: Two isolates of Beauveria bassiana （ Balsamo-Crivelli ） Vuillemin and one isolate of Isaria fumosorosea Wize were isolated from Diaphorina citri Kuwayama （ Hemiptera: Liviidae ） , a vector of huanglongbing （ citrus greening disease ） . The ability of these isolates to kill D. citri , two Cacopsylla species （ Hemiptera: Psyllidae ） , and the brown citrus aphid, Toxoptera citricida （ Kirkaldy ） and the eﬀect of temperature in vitro on their growth were investigated. Infection with all three isolates resulted in high mortality for D. citri . In the Cacopsylla spp. and T. citricida , some isolates caused consistent mortality, but this varied among isolates. Mycelial growth of the three isolates was vigor- ous at 20–30 (cid:155) C. The two isolates of B. bassiana grew well at 25 (cid:155) C, while the I. fumosorosea isolate grew well at 25–30 (cid:155) C, indicating that the optimal growth temperature varied among the isolates.
