Aim of this study is determining pathogens of Ips typographus from Eastern Black Sea Region in Turkey.
Samples collected from the field were taken to laboratuar as soon as possible. Microscopic examination was completed by dissection with Ringer's solution.
780 Ips typographus beetles from Giresun, Rize and Artvin were examined. Gregarines were observed in the populations of I. typographus in the three regions. 27 of 780 beetles were found to be infected by the Gregarina typographi. Total rate of infection was 3.4% in three localities. During the study several life stages of the gregarine pathogen (trophozoite, gamont, Cysts and associative form) were observed. Gametocysts were spherical and from 77 to 85 μm in diameter. Total lengths of solitary gamonts were measured. from 90 to 155 μm. Measurements of gamonts and gametocysts of G. typographi were given and compared with other gregarines isolated from bark beetles. This pathogen is described as Gregarina typographi.
The gregarine pathogen of Ips typographus is reported from Turkey for the first time.
本研究旨在确定土耳其黑海东部地区云杉八齿小蠹的病原体。
从野外采集的样本尽快带回实验室。用林格氏液进行解剖后完成显微镜检查。
对来自吉雷松、里泽和阿尔特温的780只云杉八齿小蠹甲虫进行了检查。在这三个地区的云杉八齿小蠹种群中观察到了簇虫。780只甲虫中有27只被云杉八齿小蠹簇虫感染。三个地点的总感染率为3.4%。在研究过程中观察到了簇虫病原体的几个生命阶段（滋养体、配子体、囊肿和结合体）。配子囊肿呈球形，直径为77至85μm。测量了单个配子体的总长度，为90至155μm。给出了云杉八齿小蠹簇虫配子体和配子囊肿的测量数据，并与从树皮甲虫中分离出的其他簇虫进行了比较。这种病原体被描述为云杉八齿小蠹簇虫。
土耳其首次报道了云杉八齿小蠹的簇虫病原体。
