This study evaluated and compared the larval consumption of different GM potatoes and affects the rate of infestation and the survival of caterpillars of S. littoralis to the exposure of IJ of S. feltiae and possibility of cooperative effect of GM potatoes and nematodes. The results show, that the nematodes killed all the caterpillars within seven days compared with the starved larvae in the same period of exposure. The average time to death and the number of nematodes successfully invaded the larvae were affected by the period of feeding on potato leaves. In the non-starved caterpillars, which received potato leaves throughout the whole period of exposure to the nematodes, the type of potato leaves had no significant effect on the number of nematodes inside cadavers (p=0.352, F=1.070) and also on the effect on the length of survival after exposure to the nematodes (p=0.7892, F=0.596). No hazardous effect on the development and survival of entomopathogenic nematode S. feltiae which successfully invaded larvae fed on modified potato (Bt or GNA) was reported.
