Prvi nalaz karantinske štetočine kestenove ose šiškarice (Drycosmus kuriphilus) u Bosni i Hercegovini
First record of quarantine pest, oriental chestnut gall wasp (Dryocosmus kuriphilus), in Bosnia and Herzegovina
Ključne reči: pitomi kesten (Castanea sativa); kestenova osa šiškarica (Dryocosmus kuriphilus); šiške; štetnost
Keywords: chestnut (Castanea sativa); chestnut gall wasp (Dryocosmus kuriphilus); galls; harmfulness; northwestern Bosnia and Herzegovina
Sažetak
U radu se prvi puta opisuje prisusvo karantinske štetočine pitomog kestena, kestenove ose šiškarice (Dryocosmus kuriphilus Yasumatsu), na Unsko-sanskom kantonu (BiH). Štetočina pripada klasi Insecta, redu Hymenoptera, porodici Cynipidae, podporodici Cynipinae, plemenu Cynipini. Poreklom je iz Kine. U Evropi je prvi puta zabeležena 2002. godine (Italija). Uzrokuje stvaranje šiški na domaćinima iz roda Castanea. Šiške sprečavaju razvoj mladara, smanjuju fotosintetsku površinu i plodonošenje pitomoga kestena. U radu je opisana biologija štetočine, simptomi napada, načini širenja, štetnost i mere zaštite. Osa šiškarica (D. kuriphilus), na Unsko-sanskom kantonu (BiH) je prvi put zabeležena 2015. godine na 34 lokacije. Smatra se novom, invazivnom štetnom vrstom u BiH. Sledećih godina se može očekivati njeno širenje u svim kestenovim šumama. Biološka kontrola moguća je parazitoidom Torymus sinensis Kamijo (Hymenoptera,Torymidae).
Abstract
The presence of oriental chestnut gall wasp, Dryocosmus kuriphilus, a quarantine pest of sweet chestnut in the Una-Sana Canton (northwestern Bosnia and Herzegovina) is described in the paper for the first time. The pest belongs to the class Insecta, order Hymenoptera, family Cynipidae, Cynipidae subfamily, tribe Cynipin, originating from China. In Europe, it was first recorded in 2002 (Italy). The pest produces galls on the hosts of Castanea genus. The galls inhibit the development of sprouts, reducing photosynthetic area and chestnut fruiting. The paper describes the biology of the pest, attack symptoms, methods of spreading, harmful effects and protection measures. In Bosnia and Herzegovina, D. kuriphilus was first recorded in 2015, across 34 locations. It is considered a new, invasive type of pest on the Una-Sana Canton territory. Its expansion on all chestnut trees is expected in the forthcoming years. Biological control is possible with Torymus sinensis Kamijo parasitoid (Hymenoptera, Torymidae).
