Abstract

The first finding of Stelidota geminata (Say) (Coleoptera: Nitidulidae) on strawberry fruits in Serbia.

Abstract

In Serbia, Stelidota geminata is for the first time found in 2011, in strawberry plantations on ripe fruits. Specimens of this species and strawberry fruits damages are established during harvest (last decade of May till beginning of July) in localities Gornja Bukovica (region of Valjevo) and Kaluđerica (region of Belgrade). The origin of this species is in USA where it is a serious strawberry pest known as "Strawberry Sap Beetle". About twenty years ago it has been accidentaly introduced in Europe. Both, adults and larvae of S. geminata feed on strawberry fruits, but the main damages originate by adults feeding. In harvest time the smell of ripen fruits attract adults from various hidden overwintering places. They feed on fruits making a deep cavities in which females lay eggs. Larvae feed in fruits too, but during their feeding and development, fruits are already damaged and decomposed. Mature larvae fall on the ground and pupate in pupal cell inside the soil. Second generation develops on fruits of various plants, and new imagoes hibernate on different hidden places. Because the harvest of damaged and decomposed strawberry fruits is impossible, an economical losses may be large. In fauna of Serbia Stelidota geminata is a new species.
