Özet

The distribution and occurrence of the insect pathogenic algae Helicosporidium sp. (Chlorophyta: Trebouxiophyceae) in the predator beetle Rhizophagus grandis (Coleoptera: Rhizophagidae)-rearing laboratories were studied and reported here for the first time. The insect pathogenic alga Helicosporidium sp. infection was observed in all R. grandis-rearing laboratories. The infection rate reached more than 20% which is significant among the samples in some R. grandis-rearing laboratories. The infection rates of the examined beetles showed noticeable differences between localities and years. There was no significant difference in the infection levels of male and female beetles. These results showed that Helicosporidium sp. is one of the factors that decrease efficiency of the R. grandis-rearing laboratories.
