Thrips – pests of tomatoes

Tripsi su sitni kukci s karakterističnim resama na krilima koji usnim ustrojem za bodenje i sisanje sišu sokove na različitim kulturama, na voća, u povrću, u ukrasnom bilju i cvijeću, na kojima pravite štete. Za rajčicu su važni kao prenosioci virusa Tomato spotted wilt virus (TSWV), kojeg isključivo prenose zaražene ličinke i odrasli nastali iz takvih ličinka. Oštećenja od tripsa na rajčici prepoznaju se kao virozne biljke, sitni plodovi, šareni i neobojeni plodovi, nekrotizirano lišće ili propadanje cijelih biljaka. Kontrola tih štetnika može se provoditi kemijskim pripravcima, pri čemu svakako valja voditi računa o rezistentnosti. Osim toga, postoje i prirodni neprijatelji tripsa, koji se mogu koristiti u biološkoj kontroli.Thrips are tiny insects with typical fringed wings and the mouth for butting and sucking.
