Abstract
During three successive years, 1983, 1984 and 1985, winged aphids were caught alive in a potato field with a conical net and with transportable suction traps.
One hundred and one aphid species or species groups were checked for their ability and efficiency in transmitting potato virus YN (PVYN) from potato to potato. Seventy-eight species or species groups were found unable to transmit PVYN, whereas twenty-three species did transmit, among them beingAphis nasturtii, Brachycaudus helichrysi, Cryptomyzus galeopsidis, Cryptomyzus ribis, Hyadaphis foeniculi, Hyalopterus pruni, Hyperomyzus lactucae, Sitobion avenae andSitobion fragariae. All species, with the exception ofA. nasturtii, are recorded the first time as vectors for PVYN.
In transmission experiments alatae caught with a conical net yielded better results than did those caught with a suction trap.
Samenvatting
Gedurende drie opeenvolgende jaren (1983, 1984, 1985) werden gevleugelde exemplaren van 101 bladluissoorten levend gevangen met een fuik en met verplaatsbare zuigvallen, en in een kas getoetst op hun vermogen om aardappelvirus YN (PVYN) van aardappel naar aardappel over te brengen.
Achtenzeventig soorten brachten het PVYN niet over. Naast de reeds algemeen bekende vectorsoorten werden nog enkele soorten gevangen die in staat bleken PVYN over te brengen in het laboratorium, te weten:Aphis nasturtii, Brachycaudus helichrysi, Cryptomyzus galeopsidis, Cryptomyzus ribis, Hyadaphis foeniculi, Hyalopterus pruni, Hyperomyzus lactucae, Sitobion avenae enSitobion fragariae.
Met bladluizen gevangen in de fuik werden betere overdrachtsresultaten behaald dan met de bladluizen gevangen in de zuigvallen.
