Laboratory experiments were done to test insecticidal activity of diatomaceous sediments from several localities in Slovenia, Greece and Serbia. The tests were carried out at different temperatures, humidity and concentrations of the agent. We observed that the most significant factor increasing insecticidal activity is silica content. The samples from Slovenian localities were more effective at higher relative humidity (75%) while the efficiency of other samples increased with lowered humidity. This fact is related to higher content of clay minerals in Slovenian samples. The results are an important contribution to the development of environmentally friendly insecticides.

COBISS.SI-ID: 6320761We compared insecticidal activity of different sediments with high content of silica. Positive correlation was observed between the mortality of rice weevil and opal-A content in the sediment, whereas SiO2 in form of quartz does not increase the insecticidal activity. The results are an important contribution to the development of environmentally friendly insecticides.
