Abstract (croatian)

Kukci iz reda Hemiptera i Thysanoptera vektori su brojnih patogenih virusa, bakterija, gljivica, fitoplazmi te spiroplazmi. Karakterizira ih brza reprodukcija te širok spektar biljaka domaćina na kojima čine direktne štete hranjenjem ili indirektne prijenosom patogenih organizama. Današnja istraživanja kukaca vektora biljnih bolesti usmjerena su na razumijevanje mehanizama kojima različiti patogeni utječu na vektore zbog unapređenja vlastitog prijenosa na prigodna domaćina, ali i na praćenje pojava novih vektora te identifikaciju uzročnika biljnih bolesti koje prenose. Lisne uši (Aphididae), štitasti moljci (Aleyroidae) i tripsi (Thripidae) vektori su mnogobrojnih biljnih virusa. Cikade vektori virusa pripadaju podporodicama Agallinae i Deltocephalinae dok su mnogobrojne ostale vrste unutar porodice Cicadellidae, Aphrophoridae i Cercopidae prijenosnici brojnih fitoplazmi i bakterija, uključujući i karantenske patogene poput bakterije Xylella fastidiosa. Istraživanja kukaca vektora uključuju proučavanja opsežnih interakcija unutar patosustava, istraživanja genskih predispozicija vektora za prijenos specifičnog patogena, sinergijske odnose virusa i endosimbiotskih bakterija u tijelu vektora, procjenjuju dinamične učinke patogena na biljke domaćine tijekom razvoja bolesti te molekularne mehanizme kojima patogeni direktno utječu na ponašanje i navike vektora. U ovom radu prikazane su biološke predispozicije različitih vektora za prijenos patogena, istaknuti su odnosi i mehanizmi utjecaja patogena na vektore te načini njihova prijenosa.

Abstract (english)

Insects from the Hemiptera and Thysanoptera order are vectors of numerous pathogenic viruses, bacteria, fungi, phytoplasmas and spiroplasmas. They are characterized by fast reproduction and a broad plant-host spectre which they damage either directly by feeding or indirectly through transmittance of pathogenic organisms. Modern-day research of insect vectors is focused on investigating the mechanisms underlying the pathogen’s influence over its vector. It also aims to discover the molecular and metabolic components in plants, pathogens and their vectors which facilitate pathogen transmission and disease spread. Aphids (Aphididae), whiteflies (Aleyroidae) and thrips (Thripidae) are most important vectors of numerous plant viruses. Leafhoppers belonging only to Agallinae and Deltocephalinae subfamilies transmit viruses whereas numerous species within Cicadellidae, Aphrophoridae and Cercopidae family, transmit phytoplasmas, bacteria as well as quarantine pathogens such as the bacteria Xylella fastidiosa. All pathogens transmitted by insect vectors use complex strategies to enhance effectiveness of their transmission and spread. Most pathogens show high specificity towards their insect vectors since certain anatomical and genetic predispositions must be appeased in order to achieve successful transmission. Pathogens also devised intriguing ways to manipulate vector behaviour and change its feeding and reproductive habits. In this review, we present biological predispositions of different vector-insects for pathogen transmission, highlight mechanisms in plant-vector-pathogen interactions and point out distinct ways of pathogen transmission.
