Abstract

The intensity and symptoms of the occurrence of cambio- and xylophagous entomofauna was studied on trees dying as a result of stress caused by a lightning strike, in pine stands of Mały Beskid and Maków Beskid, in which there were lightning-struck areas (Tab. 1). In order to determine the effect of stress caused by a lightning strike on the conditions affecting infestation of pine trees by individual insect species, entomofauna occurring on trees that died from other causes was simultaneously examined. The studies showed that the lightning-struck areas consisted of 4 to 6 dying pine trees. It has been found that the pine trees dying in the lightning-struck areas were infested by a group of thirteen species of cambio- and xylophagous insects. The first insects that inhabited pine trees in late spring and in summer, formed a group of: Tetropium sp., Arhopalus rusticus (L.), Sirex noctilio Fabr. and Pissodes pini (L.). In the subsequent year, the incidence was particularly high in the case of Tetropium sp., Rhagium inquisitor (L.), Arhopalus rusticus, Xyloterus lineatus (Oliv.), Pissodes. pini, Ips acuminatus (Gyll.) and Hylurgops palliatus Gyll. (Tab. 2). The group of cambio- and xylophagous insects inhabiting pines dying for other reasons was more numerous, as it consisted of fifteen species. Pissodes pini, Tomicus piniperda (L.), Ips acuminatus, Rhagium inquisitor, Arhopalus rusticus and Pityophthorus pityographus (Ratz.) showed high incidence on pines outside the lightningstruck areas. Stress caused by a lightning strike increased the prevalence of the following species: Tetropium sp., Rhagium inquisitor, Arhopalus rusticus, Xyloterus lineatus, Hylurgops palliatus and Elateroides dermestoides (L.), while it prevented colonization or decreased incidence of: Tomicus piniperda, Phaenops cyanea (Fabr.), Pissodes pini, Pityophthorus pityographus, Pityogenes bidentatus (Herbst) and Sirex noctilio Fabr. (Tab. 2). In the case of four species: Tomicus piniperda, Phaenops cyanea, Tetropium sp. and Elateroides dermestoides differences between the incidence on trees struck by a lightning and those which died from other causes, proved to be statistically significant (Tab. 3). The intensity of infestation of pine stems in lightning-struck areas and those dying from other causes was also different. In lightning-struck areas, Tetropium sp., Rhagium inquisitor, Pissodes pini, Xyloterus lineatus and Hylurgops palliatus were characterized by the largest range of occurrence on tree stems, i.e. on more than 10% of their length (Tab. 2), while on the pine trees that died from other causes, the high infestation intensity was recorded in the case of Pissodes pini and Tomicus piniperda. Given the intensity of tree infestation, it can be stated that only four species, i.e.: Molorchus minor (L.), Ips acuminatus, Monochamus galloprovincialis (Oliv.) and Pityogenes bidentatus did not react to the fact whether the pines were struck by a lightning or they were weakened or damaged by another stress factor (Tab. 4). On pine trees struck by atmospheric discharges, increased infestation intensity was observed in the case of: Hylurgops palliatus, Rhagium inquisitor, Tetropium fuscum, Arhopalus rusticus, Xyloterus lineatus, Elateroides dermestoides and Sirex noctilio. Decreased infestation intensity was observed in the following species: Tomicus piniperda, Phaenops cyanea, Pissodes pini and Pityophthorus pityographus (Tab. 4). The above described studies suggest that the physiological condition of trees struck by the lightning, as well as the succession of cambio- and xylophagous insects on those trees was different as compared to those dying from other causes.

Abstract in PolishW drzewostanach sosnowych badano entomofaunę kambio- i ksylofagiczną na drzewach zamierających w wyniku stresu piorunowego. Stwierdzono, że frekwencja i intensywność opanowania sosen z pogromisk, a także zamierających z innych przyczyn, była różna dla wielu gatunków owadów. Sosny na pogromiskach były opanowywane przez zespół trzynastu gatunków owadów. Stres piorunowy zwiększał frekwencję występowania na sosnach: Tetropium sp., Rhagium inquisitor (L.), Arhopalus rusticus (L.), Xyloterus lineatus (Oliv.), Hylurgops palliatus (Gyll.) i Elateroides dermestoides (L.), natomiast uniemożliwiał zasiedlenia lub zmniejszał frekwencję i intensywność zasiedlenia: Tomicus piniperda (L.), Phaenops cyanea (Fabr.), Pissodes pini (L.), Pityophthorus pityographus (Ratz.), Pityogenes bidentatus (Herbst) i Sirex noctilio Fabr. Tylko cztery gatunki – Molorchus minor (L.), Ips acuminatus (Gyll.), Monochamus galloprovincialis (Oliv.) i Pityogenes bidentatus (Herbst) – nie reagowały na porażenie sosny przez piorun czy osłabienie przez inny czynnik stresujący.
