  PREFERENSI DAN TANGGAP FUNGSIONAL PARASITOID HEMIPTARSENUS VARICORNIS (GIRAULT) (HYMENOPTERA: EULOPHIDAE) PADA LARVA LALAT PENGOROK DAUN KENTANG Hidrayani 1 , Aunu Rauf 2 , Soemartono Sosromarsono 2 , dan Utomo Kartosuwondo 2  ABSTRACT  The preference and functional response of Parasitoid Hemiptarsenus varicornis (Girault) (Hymenoptera:Eulophidae) on host larvae of potato leafminers. The preference of Hemiptarsenus varicornis (Girault) on host larvae of potato leafminers ( Liriomyza huidobrensis ) and their functional response on host abundance were studied in laboratory. The preference test was conducted by releasing a female parasitoid in a cage containing two redbean leaves, one with 2 nd instar and another one with 3 rd instar. The functional response test was conducted by providing 3 rd instar with density 1, 4, 6, 8, 10, and 13 larvae per leaf. The result showed that H. varicornis had the preference on 3 rd instar larvae compared to 2 nd instar, either for para...
