Abstract

The study investigated the insecticidal efficacy of six Croatian inert dusts (D-01, JU-1, MA-4, MR-10, OP-4 and PD-1) and diatomaceous earth Celatom Mn-51® against red flour beetle Tribolium castaneum Herbst on wheat. The influence of mentioned dusts on the offspring development has also been investigated. The experiment was carried out in laboratory conditions on insects aged 7-21 days. Doses of 600 and 700 mg \(kg^-1\) were tested for JU-1, MR-10, OP-4 and PD-1 and 300 and 400 mg \(kg^-1\) for D-01, MA-4 and Celatom Mn-51® alongside previously mentioned doses (600 and 700 mg \(kg^-1\) ). The mortality rate of red flour beetle was determined on the 7th and 14th day of exposure and progeny was determined by number of developed adults. Regarding the insecticidal efficacy on T. castaneum
the tested inert dusts can be divided into three groups: very effective dusts (D-01 (\(LD_{90}\) = 600 mg \(kg^-1\) ), MA-4 (\(LD_{90}\) = 500 mg \(kg^-1\) ), medium-effective dusts (JU-1 and PD-1) and low-efficient dusts (OP-4 and MR-10). Based on the obtained results it can be concluded that there are some resources of inert dusts with high insecticidal potential in the Republic of Croatia.
