The results of previous research on the activity of entomopathogenic nematodes against harmful Thysanoptera species (particularly against Frankliniella occidentalis) and so far recorded entomophilic (parasitic) nematodes (Thripinema genus) in the body of thrips are presented in the paper. Most probably in the near future entomopathogenic nematodes will partly substitute for insecticides in controlling thrips and other plant pests. The investigation of the mode of action and the bionomics of entomophilic nematodes will be required to improve their activity in controlling thrips.

In 2008 we continued our research on insecticidal activity of three samples of diatomaceous earth (DE) against adults of rice weevil. The efficiency of DE samples from Greece, Serbia and Slovenia was examined at three temperatures (15, 20, and 25°C), two different values of relative humidity (55 and 75 %), and at four concentrations (100, 300, 500, and 900 ppm). Diatomaceous earth was the most effective at 30°C and 75 % of relative humidity. The least effect of the samples was observed at 25°C and 55 % of relative humidity.
