The vine cicada, Psalmocharias alhageos (Kolenati 1857) (Homoptera: Cicadidae), is an important pest of vineyards. The nymphs of cicada damage the trees by feeding on roots, adult insects on young buds and by oviposition under branch barks. Nourishing roots by nymphs leads to the weakness of the tree and hinder its growth. The high density oviposition of adult insects inside young barks causes withering of branches. The efficacy of a kaolin-based formulation (Sepidan®) along with diatomaceous earth (Sayan®) and essential oil to control field infestations of the vine cicada, P alhageos was investigated in Qom province of Iran. The results indicate that kaolin plus diatom suppresses the vine cicada egg laying activity (50% reduction in comparison to untreated control). Also the number of healthy shoots in treated trees was increased, and conversely number of infected shoots was decreased. The highest product yield was obtained in treated trees. In overall, Kaolin and diatom particles successfully suppressed P alhageos oviposition and provided season-long insect control. Consistent with previous findings, the Sepidan® kaolin particles proved to be a promising alternative method to synthetic insecticides and could be used to control P alhageos in vine groves.
