Abstract

The research aimed at studying the level of attack and population of mealybug cassava in multiple cassava planting locations in Lampung Province takes place from September 2017 to January 2018. Sampling was carried out in several cassava planting locations in five villages in five sub-districts in South Lampung, Central Lampung, and East Lampung. Attack crop samples were ten plants that were systematically chosen, each at five sample points located on four diagonal lines and one at the midpoint of each field. One plant at each sample point was selected for observation of the mealybug population. The laboratory process is carried out at the Plant Pests Laboratory, Plant Protection Department, Faculty of Agriculture, University of Lampung. The results showed that mealybug  were found in all locations of observation with a low population density of 0.68-3.26 individuals. per 3 leaves. Location of cassava planting does not affect the population of mealybug  but this location affects crop damage which ranges from 47 - 59%. Damage to plants in South Lampung is lower than damage to plants in East Lampung and Tanjung Bintang.

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%).
