Abstract


ABSTRAK. Penelitian yang bertujuan mengetahui kemurnian predator introduksi, keamanan jaring kasa Agronet
(568 lubang/cm²), serta kemangkusan predator introduksi Amblyseius swirskii dan Orius laevigatus, dilaksanakan
sejak bulan Oktober 2007 sampai dengan April 2008 di Laboratorium Entomologi dan Fitopatologi Balai Penelitian
Tanaman Sayuran Lembang (±1.250 m dpl.) dan di Rumah Kasa CV ASB Farm di Desa Cigugurgirang, Kecamatan
Parongpong, Kabupaten Bandung Barat (±1.100 m dpl.). Uji kemurnian dan keamanan dilakukan di laboratorium,
sedang uji kemangkusan predator dilaksanakan di rumah kasa dalam mengendalikan hama T. parvispinus pada
tanaman paprika. Penelitian di rumah kasa menguji empat macam perlakuan pengendalian, yaitu dengan: (A) 75
ekor A.swirskii/m2, (B) O.laevigatus 5 ekor/m2, (C) kombinasi 40 ekor A.swirskii + 3 ekor O.laevigatus/m2, dan (D)
kontrol (tanpa predator). Hasil penelitian menunjukkan bahwa dalam kemasan predator introduksi A.swirskii dan
O.laevigatus hanya dijumpai kedua jenis predator tersebut dan tungau tepung sebagai makanan A.swirskii. Organisme
hama dan penyakit tidak ditemukan dalam kemasan, sehingga kedua predator tersebut layak diintroduksi ke Indonesia.
Jaring kasa Agronet yang digunakan memiliki anyaman yang cukup rapat, sehingga tidak memungkinkan predatorpredator
tersebut melaluinya. Dengan demikian, jaring tersebut aman digunakan sebagai dinding rumah kasa. Dari
percobaan di rumah kasa diketahui bahwa A.swirskii efektif mengendalikan trips, sehingga hasil panen paprika dapat
dipertahankan.

ABSTRACT. Prabaningrum, L. and T.K. Moekasan. 2010. Effectiveness of Amblyseius swirskii and Orius
laevigatus Against Thrips parvispinus on Sweet Pepper. The experiment was aimed to determine the purity of
introductory predators, safety of the Agronet screen (568 holes/cm²), and effectiveness of introductory predators
A. swirskii and O.laevigatus. The research was conducted from October 2007 until April 2008 in the Laboratory of
Entomology and Phytopathology Division of Indonesian Vegetables Research Institute (IVEGRI) (1,250 m asl.) and
in the Greenhouse of CV ASB Farm in Cigugurgirang Village, Parongpong Subdistrict, West Bandung District (1,100
m asl.), West Java. Purity and safety tests were conducted in the laboratory and the effectiveness test was conducted
in the greenhouse. Four treatments were tested in the greenhouse i.e. the application of (A) A.swirskii (75/m2), (B)
O.laevigatus (5/m2), (C) A.swirskii (40/m2) + O.laevigatus (3/m2), and (D) check (without predators). The results
showed that there were only A.swirskii, O.laevigatus, and powder mites as food in the containers of the introductory
predators. There were no pests and diseases in the container, so that the predators can be introduced. The net of the
screen was plaited closely, so that A.swirskii and O.laevigatus did not able to pass through. It was indicated that the
screen was safe to be used as the wall of screenhouse. The experiment in the screenhouse indicated that A.swirskii
suppressed thrips population effectively, so that the sweet pepper yield would be sustained.
