Introduction. The influence of infection with two species of entomopathogenic nematodes of Steinernematidae family on metabolism of glycogen and trehalose of the host was studied. Material and methods. Last instar larvae (L₇) of Galleria mellonella were experimentally infected with Steinernema affinis and S. feltiae. At 6, 12, 18 and 24 h after infection concentrations of trehalose and glycogen as well as activity of trehalase and α-amylase were determined. Results. The content of glycogen was lower in insects infected with S. feltiae than in the controls and animals infected with S. affinis. The content of trehalose was higher in insects from both infected groups than in the controls. Its concentration was slightly higher in larvae infected with S. affinis than in those infected with S. feltiae. The activity of α-amylase after infection with S. affinis was low. It was significantly higher in insects infected with S. feltiae. In animals of both infected groups, following a significant reduction at 6 h, the activity of trehalase remained at a similar level, higher than in the controls. In the paper the effects of infection with (i) different species of entomopathogenic nematodes and (ii) the importance of the developmental stage of the insect-host for changes in its metabolism of glycogen and trehalose were discussed.

Background. The influence of infection with two species of entomopathogenic nematodes of Steinernematidae family on the activity of superoxide dismutase (SOD) of the host was studied. Material and methods. Last instar larvae of Galleria mellonella were experimentally infected with Steinernema affinis and S. feltiae at 20 invasive juveniles per insect. At 6, 12, 18, 24 and 36 h after infection activity of SOD was determined in extracts from infected and control insects. Results. The activity of SOD decreased gradually in the controls during the experiment. The activity of enzyme was 2-4-times higher in insects from both infected groups than in the control. During the first 12 h of infection the activity of SOD in insects infected with S. feltiae was higher than in those infected with S. affinis, then the activity of enzyme in the insects of both infected groups stayed at a similar level. A significant decrease of SOD activity in infected was recorded in second day of the infection.

Nematodes of the Brevibuccidae family were stated among spiders of the Theraphosidae family (the South American species), which were bred in Poland. The first sign of infection was anorexia which led to gradually increasing lethargy progressed to a huddled posture. Additionally, a white discharge with nematodes between mouth and chelicerae was noted. All of the derived nematodes were morphologically identified and determined to the species Tarantobelus arachnicida. A molecular analysis covered amplification and sequencing of small subunit ribosomal RNA (18S rRNA). A post mortem examination demonstrated the presence of nematodes not only near the chelicerae, but also inside the intestine, hence the source of infection might be insects used as a food. The research showed that such kind of infection is an important disease, which poses a serious risk to the breeding spiders. To date there is no effective treatment, however, we demonstrated that usage of the Lugol’s solution seems to be promising.
