Significantly, more Ips typographus were caught with slit traps than with insecticide treated trap tipis. Both trap systems caught more beetles than common trap logs during the whole study (two periods: one month in spring and one month in summer). Slit traps brought evidence of similar trapping success in spring and summer insecticide treated trap tipis and trap logs were approached by 1. typographus more intensely in spring I. typographus were killed after coming in contact with the Pyrethroid sprayed bark surface of trap tipi log sections in both periods of investigation. Despite the presence of three attractive catching devices, infestation of standing trees by bark beetles (next to the test area) could not be avoided. The bark beetle predator, Thanasimus formicarius was found frequently on trap tipis and was also killed b) the insecticide coating.1 aKoleva, Petia1 aKolev, Nikolay1 aSchopf, Axel1 aWegensteiner, Rudolf  uhttps://weevil.myspecies.info/efficiency-insecticide-treated-log-sections-trap-tipis-european-spruce-bark-beetle-ips-typographus-c01909nas a2200205   4500008004100000020001400041245012700055210006900182260000800251300001200259490000700271520115700278653002001435100002401455700002501479700002301504700001901527700002201546856013501568       2010                        eng d  a0324-077000aFurther Studies on the Occurrence of Natural Enemies of Ips typographus (Coleoptera: Curculionidae: Scolytinae) in Georgia0 aFurther Studies on the Occurrence of Natural Enemies of Ips typo  cAug  a131-1380 v623 aNatural enemy complex of the bark beetle - Ips typographus, a pest insect of Picea orientalis in Georgia was investigated. Their frequency in different elevation zones and different years in managed and unmanaged forests of Georgia was determined. The protozoan pathogen Gregarina typographi and microsporidium Chytridiopsis typographi were observed in the investigated beetles. While the gregarine was found each year and at every altitude investigated, the microsporidium was observed in beetles with a lower frequncy and not at every studied site. Additionally, a fungal pathogen Fusarium sp. in a low frequency was detected in part of the studied beetles. Nematodes were found free in the haemolymph and in the gut lumen as well but only one nematode species, Contortylenchus diplogaster could be identified. Larvae of the parasitoids Tomicobia seitneri and Ropalophorus clavicornis were also observed at different elevations. Predators Nudobius lent us and Thanasimus formicarius were detected in galleries off typographus. The amount of the pest larvae consumed by both species within twenty four hours was determined under laboratory conditions.10aIps typographus1 aKereselidze, Manana1 aWegensteiner, Rudolf1 aGoginashvili, Nana1 aTvaradze, Meri1 aPilarska, Daniela  uhttps://weevil.myspecies.info/further-studies-occurrence-natural-enemies-ips-typographus-coleoptera-curculionidae-scolytinae-georg01404nas a2200169   4500008004100000020001400041245011600055210006900171260000900240300001200249490000700261520076900268653002001037100002401057700002501081856012801106       2007                        eng d  a1027-311500aOccurrence of pathogens and parasites in Ips typographus L. from spruce stands (Picea orientalis L.) in Georgia0 aOccurrence of pathogens and parasites in Ips typographus L from   c2007  a207-2100 v303 aOccurrence of pathogens was investigated in the spruce bark beetle Ips typographus from two different sampling plots in Borjomi region at 900m above sea level, collected in September 2004.

Log sections were cut and incubated in the laboratory; emerging beetles were removed and identified. Furthermore, pathogen occurrence was investigated in Ips typographus L. (Coleoptera, Curculionidae) from these six sites. In total eight bark beetle species were found; Ips typographus and Pityogenes chalcographus occurred in the logs from all locations, Ips amitinus only in higher elevation. Furthermore, fewer individuals emerged belonging to the species: Hvlurgops glabratus, Polygraphus poligraphus, Dryocoetes autographus, Pitvophthorus pityographus and Trypodendron lineatum. Six pathogen species were found in I. typographus (ItEPV, Gregarina typographi, Mattesia typographi, Chytridiopsis typographi, Nosema typographi, Unikaryon montanum). Infection rates varied in beetles from the different locations.10aIps typographus1 aGasperl, Hubert1 aWegensteiner, Rudolf  uhttps://weevil.myspecies.info/investigations-altitude-related-occurrence-bark-beetles-and-pathogens-ips-typographus-l-1758-coleopt
