Sažetak
The brown marmorated stink bug (Halyiomorpha halys, Stål, 1855) is an invasive polyphagous
pest native to eastern Asia. In recent years, it has been causing more and more damage to a large number of agricultural crops. Among the fruit species in Croatia, the greatest damage was recorded on pears. The aim of this study was to evaluate the efficacy of the topical application of eight active substances in the control of adult forms of the brown marmorated stinky bugs, considering that the adult forms are much more resistant to insecticidal action compared to the nymphs. Active substances used in treatments were acetamiprid, spinetoram, deltamethrin, spirotetramat, azadirachtin, nettle and willow oil extract, kaoline, and silicone polymers.
Adult forms of the pest were collected with an entomological catcher in the pear orchard of Agricultural Institute Osijek and placed in plastic containers. Each treatment had three replicates. Treatments with the highest mortality rate (100% after 48 h), were statistically significant regarding spinetoram and silicone polymers. The high mortality rate of treatment with silicone polymers was not expected. The research on insecticides with the highest efficacy will continue in field experiments to determine the reproducibility of the results under uncontrolled conditions. It is important to make the best choice of preparation according to knowledge of its efficacy.
