Abstract

This research was carried out in three fields of the potato plantation which differed in altitude in Solok prefecture. Desfectirely Aphid identification was done in the laboratory of Agronomy, The Faculty of Agriculture, Andalas University Padang and in Institute of Fruit Research in Solok. The aphid population fluctuation was observed by capturing the aphid flying by installing three traps of Moericke in the potato plantation in each area. The results of the research showed that the aphid population in the potato plantation was lower in the area of Rimbo Data (1.700 m dpl) compared with the area of Aia Batumbuak (1.350 m dpl) and Sukarami (1.000 m dpl). The period without aphid will only be found in the area of Rimbo Data at October and January. The type of dominant aphid in Rimbo Data was Macrosiphum euphorbiae, in Aia Batumbuak and Sukarami were Aphis fabae. Key Word : Altitude, aphid, potato, season
