ASIAN APRICOT APHID, MYZUS MUMECOLA (MATSUMURA, 1917) (HEMIPTERA: APHIDIDAE), FOUND IN SERBIA

Asian apricot aphid, Myzus mumecola (Matsumura, 1917) (Hemiptera: Aphididae, Aphidinae) has been found during spring of 2021 in many localities in Serbia (Ljig, Smederevo, Velika Plana, Belgrade and Šid) on cultivated apricot. The species is of Asian origin, a few years ago it was found in Italy and in Hungary. Research of the species indicates that it is rapidly widening its distribution in Europe. Damages made to apricot trees by feeding on leaves at young branches and making red galls are significant. Presence, damage and biology of M. mumecola needs to be studied in the future, especially its secondary hosts which are not enough known

Krivonoga jelina vaš Clnara curvipes (Patch) (Aphidide, Homoptera) nova štetočina dugoigličave jele u Srbiji

During 2001 and 2002 in Novi Sad, the presence of Cinara curvipes (Patch) was observed on several Abies concolor trees and on individual branches of Cedrus atlantica. The finding is very interesting as this species is widely distributed in USA, Canada and Mexico. It is new in the aphid fauna of Serbia and Serbia is the second European country in which it has been identified.Tokom 2001. i 2002. godine u Novom Sadu na više stabala Abies concolor i pojedinim granama Cedrus atlantica utvrđeno je prisustvo Cinara curvipes (Patch). Nalaz je veoma zanimljiv pošto se radi o vrsti široko rasprostranjenoj u SAD-u, Kanadi i Meksiku koja je nedavno introdukovana u Evropu i nova je za afidofaunu naše zemlje. Srbija je druga evropska zemlja u kojoj je utvrđena

PRESENCE OF NORTH AMERICAN APHID DREPANAPHIS ACERIFOLIAE (THOMAS, 1878) (HEMIPTERA: APHIDIDAE: DREPANOSIPHINAE) IN SERBIA

The painted maple aphid, Drepanaphis acerifoliae (Thomas, 1878), is present on Acer saccharinum L. (silver maple) in Serbia. It was found for the first time in 2019 in parks in Novi Sad, and in 2020 it was registered in Belgrade. It is a North American species that has been extending its distribution in Europe since 1992. Serbia is the fourth European country in which it has been found, following Italy, Spain and Hungary. Drepanaphis acerifoliae was found to be present on all examined A. saccharinum L. trees where it is usually very numerous. It was not found on A. platanoides L., A. campestre L., A. pseudoplatanus L. or A. negundo L. The morphology of viviparous parthenogenetic females, oviparous females and males is presented, with original drawings and photos

First Records of Two Species of the Genus Illinoia Wilson, 1910 (Hemiptera: Aphididae) in Bulgaria

Two aphid species of the genus Illinoia Wilson, 1910 are reported for the first time in Bulgaria, Illinoia (Illinoia) azaleae (Mason, 1925) and Illinoia (Masonaphis) lambersi (MacGillivray, 1960). They are pest mainly on Rhododendron sp. and were collected from important ornamental plants in two garden centres in Sofia and the village of Ravda, Burgas Region. The new records are provided with original illustrations based on Bulgarian materials

Morfološka karakterizacija Myzus persicae (Hemiptera: Aphididae) sa breskve i duvana u Srbiji i Crnoj Gori

Multivariate morphometric analysis was used to compare nine characteristics of 47 populations of Myzus persicae (Sulzer) originating from two host-plants, peach and tobacco, from 13 localities in 2004 and 34 localities in 2005, in Serbia and Montenegro. Multivariant discriminant analysis showed there to be a distinct discrimination between the populations from the peach and tobacco host-plants. The most important discrimination characteristics are the ultimate rostral segment length and processes terminalis length, which are greater in the aphids from tobacco than in those from peach. This is the first indication that in this part of Europe there are two subspecies: M. persicae (Sulzer) and M. persicae nicotianae Blackman.Multivarijantna analiza varijanse korišćena je za poređenje devet karaktera kod 47 populacija Myzus persicae (Sulzer) sa dve biljke domaćina, breskve i duvana. Uzorci su uzeti sa 13 lokaliteta u 2004. i 34 lokaliteta u 2005. godini u Srbiji i Crnoj Gori. Multivarijantna diskriminatorna analiza pokazala je da se vaši sa duvana jasno odvajaju od vašiju sa breskve. Glavni diskriminatorni karakteri su dužina vršnog segmenta rostruma i dužina vršnog dela šestog segmenta pipka koji su značajno duži kod vašiju sa duvana u odnosu na vaši sa breskve. Ovo su prvi podaci koji govore o postojanju dve podvrste u ovom delu Evrope: M. persicae persicae (Sulzer) i M. persicae nicotianae Blackman

Let biljnih vaši, potencionalnih vektora virusa, u usevu lucerke u Srbiji

Flight activity of aphids as potential vectors of viral infection of alfalfa plants were monitored in Serbia for the first time in Europe. Research was conducted at the location Progar (Srem) for two years using six yellow water traps. A total of 1626 individual winged aphids were collected. The collected specimens were classified into 49 different taxa. During the two-year study, maximum population density of aphids and maximum potential vector activity were noted at the beginning of June, during the second alfalfa intercut. More than 65% of the collected specimens were potential vectors of the most important alfalfa viruses, Alfalfa mosaic virus (AMV) and Cucumber mosaic virus (CMV). The most numerous winged aphid species on alfalfa were Aphis craccivora, Aphis fabae, Aphis gossypii, Aphis pomi/ spiraecola and Therioaphis trifolii. The Morisita-Horn similarity index was used to calculate similarities in species composition among the traps. High values of this index showed no significant differences among the aphids in traps. It indicates that one trap alone could provide good insight into the abundance, aphid diversity and number of potential vector species in small alfalfa fields.Praćenje leta biljnih vaši, potencijalnih vektora virusa, na lucerki istraživano je na teritoriji Srbije po prvi put u Evropi. Let biljnih vaši na lucerki praćen je na lokalitetu Progar (Srem) tokom dve godine korišćenjem šest žutih lovnih klopki. Sakupljeno je ukupno 1626 krilatih jedinki biljnih vaši. Prikupljene jedinke su klasifikovane u 49 različitih taksona. Tokom dve godine praćenja leta, najveća brojnost biljnih vaši, kao i najveća aktivnost potencijalnih vektora, registrovana je početkom juna, u drugom otkosu lucerke. Više od 65% prikupljenih jedinki su potencijalni vektori dva najvažnija virusa lucerke: virusa mozaika lucerke - Alfalfa mosaic virus (AMV) i virusa mozaika krastavca - Cucumber mosaic virus (CMV). Najbrojnije biljne vaši u klopkama na lucerki bile su: Aphis craccivora, Aphis fabae, Aphis gossypii, Aphis pomi/spiraecola i Therioaphis trifolii. U cilju poređenja sličnosti sastava biljnih vaši u lovnim klopkama, izračunat je Morisita-Horn indeks sličnosti. Visoke vrednosti ovog indeksa ukazuju da nema značajnih razlika u sastavu afidofaune poređenih klopki. Dovoljna je samo jedna lovna klopka radi uvida u brojnost i diverzitet biljnih vaši potencijalnih vektora virusa u lucerki

Potencijalna opasnost od pojave invazivne vaši Acyrthosiphon kondoi Shinji, 1938 (Hemiptera: Aphididae) na lucerki u Srbiji

Aphids (Hemiptera: Aphididae) are important pests of alfalfa all over the world. One of the most important ones is a blue alfalfa aphid - Acyrthosiphon kondoi Shinji. Morphology of the species is very similar to a green alfalfa aphid - Acyrthosipom pisum Harris. Saliva of A. kondoi is very toxic and this is why it is more important than other pest species. It can cause alfalfa wilting. Recently, A. kondoi was found in Europe, in Greece and France. It is expected to appear in other European countries. The presence of A. kondoi in Serbia was investigated from 2011 to 2015 on alfalfa and other host plants and it was not found.Biljne vaši (Hemiptera: Aphididae) svojom aktivnošću nanose značajne ekonomske gubitke u proizvodnji lucerke širom sveta. Jedna od najznačajnijih štetočina ove gajene biljke u svetu je plava lucerkina vaš - Acyrthosiphon kondoi Shinji. Ova vrsta je morfološki veoma slična zelenoj lucerkinoj vaši - Acyrthosipom pisum Harris. Zbog toksičnog sadržaja sekreta pljuvačnih žlezda A. kondoi je štetnija od drugih vaši koje se hrane na lucerki. Ishranom može prouzrokovati uvenuće biljaka lucerke. Acyrthosiphon kondoi je nedavno registrovana u Evropi, Grčkoj i Francuskoj. Postoji mogućnost pojave ove invazivne vrste i značajne štetočine lucerke u drugim evropskim zemljama. Tokom četvorogodišnjih istraživanja (2011-2015), prisustvo ove vaši nije utvrđeno na lucerki i drugim biljkama domaćinima na teritoriji Srbije
