Abstract

Penelitian ini bertujuan untuk mempelajari patogenisitas jamur entomopatogen Beauveria bassiana
(Bals.) Vuill. (Deuteromycotina: Hyphomycetes) yang diisolasi dari berbagai lokasi dan jenis inang di
Indonesia terhadap telur Crocidolomia pavonana (F.) (Lepidoptera: Pyralidae). Pada percobaan ini
digunakan kelompok telur dan 13 isolat B. bassiana, yaitu Bb-La1, Bb-La2, Bb-La3, Bb-La4, Bb-Hh1, Bb-
Hh2, Bb-Cp, Bb-Thr, Bb-Sl, Bb-Nl, Bb-725, Bb-Cc, Bb-Rl. Aplikasi jamur dilakukan dengan cara
perendaman kelompok telur C. Pavonana ke dalam suspensi konidia selama 60 detik. Hasil penelitian
menunjukkan bahwa tidak ada pengaruh aplikasi seluruh isolat B. bassiana terhadap mortalitas telur, akan
tetapi beberapa larva instar I mati 3 hari setelah keluar dari telur. Mortalitas larva instar I maksimal 91.00%.

ABSTRACT
The purpose of this research was to study the pathogenicity of Beauveria bassiana (Bals.) Vuill.
(Deuteromycotina: Hyphomycetes) originated from different geographical locations and host ranges in
Indonesia to eggs of Crocidolomia pavonana (F.) (Lepidoptera: Pyralidae). Egg clusters and thirteen
isolates, i.e., Bb-La1, Bb-La2, Bb-La3, Bb-La4, Bb-Hh1, Bb-Hh2, Bb-Cp, Bb-Thr, Bb-Sl, Bb-Nl, Bb-725,
Bb-Cc, Bb-Rl were used in the experiment. Egg cluster directly inoculated with conidial suspensions using
dipping methods in 60 seconds. The results of experiment showed that there was no effect of all isolates on
egg mortality, but that some first instar larvae died 3 days after eclosion. The maximum mortality of first
instar larvae was 91.00%.
Key words: Beauveria bassiana, pathogenicity, isolates, Crocidolomia pavonana eggs
