ABSTRACT
Idiopterus nephrelepidis (Hemiptera: Aphididae) is reported for the first time in Bulgaria on ornamental ferns in four greenhouses in Sofia and Varna. Dense colonies of apterous viviparous females and larvae were observed. The established host plants are Nephrolepis exaltata, Asplenium nidus and Pteris cretica. Infested ferns exhibit leaf deformation. The aphids were reared in laboratory conditions for four months. A morphometric study of apterae was carried out. Taking into account the presence of host plants of I. nephrelepidis in Bulgaria which are native to the local flora and the reports of the aphid from the Balkan area, it may spread in the country outdoors.
