Some observations of the weevil Polydrusus (Polydrusus) picus ssp. picus (Fabricius 1792)

Abstract

Polydrusus (Polydrusus) picus ssp. picus (Fabricius, 1792) which belongs to the family of weevils (Coleoptera: Curculionidae) has been recorded in a high number during the spring 2017 in Belgrade area, Serbia. The adults were detected on aronia plants firstly, and than on strawberry plants and Celltis occidentalis L. leaves. The most of them were found feeding on the youngest leaves. On aronia and C. occidentalis plants, adults fed on young leaves along the periphery of the leaf blade and between the veins. On strawberry plants, adults fed on the same way on young leaves, but also damaged the leaf petioles, sepals, floral and fructal peduncles. High number of adults were found on aronia plants, but the most significant damages were detected on strawberry plants.

Tokom proleća 2017. godine, na više lokacija na području Beograda (Srbija), utvrđeno je prisustvo brojnih imaga rilaša Polydrusus (Polydrusus) picus ssp. picus (Fabricius, 1792). Prva imaga nađena su na sadnicama aronije u prodaji, a potom su u većem broju registrovana na aroniji i jagodi u okućnicama i na američkom kopriviću (Celtis occidentalis L.). Odrasle jedinke su se hranile grizući mlade listove po obodu, ostavljajući karakteristična oštećenja.
