Abstract

Lampung is one of the Province that potential to cacao produce. Stem borer Zeuzera coffeae (Lepidoptera: Cossidae) is one of the pests that often be found, besides Conopomorpha cramerella and Helopelthis sp. Z. coffeae can bore branches and stems it caused xylem damage, plant break easily or plant growth inhibited. The research were conducted from September to October 2017. Sampling was doing at smallholder cocoa plantation in Cipadang Village, Gedongtataan Sub-district, Pesawaran District. Survey was doing to observe pest attacks characteristic, inventory of attacked host, identification of symptoms, and number of fruits. Attack intensity in young plant is higher than in older plants. In 4 years plants the intensity of attack and damage are 11,34% and 7,73%. While the intensity of attack and damage in the 9 plant years are 7,50% and 5,00%.   Keywords: attack intensity, cocoa, stem borer, Zeuzera sp.

Abstract

Spodoptera frugiperda J.E. Smith merupakan serangga invasif yang telah menjadi hama pada tanaman jagung (Zea mays) di Indonesia (Kementan, 2019). S. frugiperda bersifat polifag. pengendalian S. frugiperda yang dapat dilakukan antara lain hayati (predator, parasitoid, dan patogen seperti jamur yang dapat menyebabkan kematian) (Nonci dkk., 2019). Penelitian ini bertujuan untuk Mempelajari kemampuan tumbuh, sporulasi dan viabilitas spora sembilan jamur entomopatogen koleksi Laboratorium Bioteknologi Pertanian, Fakultas Pertanian Universitas Lampung. Penelitian ini dilakukan pada bulan Juli 2020 sampai Mei 2021 di Laboratorium Bioteknologi Pertanian, Laboratorium Penyakit Tumbuhan dan Laboratorium Ilmu Hama Tumbuhan, Fakultas Pertanian, Universitas Lampung. Pada penelitian ini terdiri dari beberapa percobaan yaitu pertumbuhan koloni sembilan jamur, sporulasi, viabilitas spora sembilan isolat jamur pada media PDA. Pertumbuhan koloni jamur tertinggi dihasilkan oleh isolat SPV (Trichoderma asperellum) (8,27 cm), sporulasi tertinggi dihasilkan oleh isolat SPV (T. asperellum) (10,10 spora/ml), viabilitas tertinggi dihasilkan oleh isolat AS8 (Talaromyces sayulitensis) (74,16%).
