چکیده

Abstrak. Entomopatogen adalah mikroorganisme yang berkemampuan menimbulkan penyakit pada serangga, antara lain virus, bakteri, cendawan, protozoa dan nematoda. Salah satu spesies cendawan entomopatogen berpotensi sebagai agens hayati pengendali serangga hama Beauveria bassiana (Balsamo) Vuillemin. Tribolium castaneaum, Tenebrio molitor, Sitophilus oryzae termasuk ordo Coleoptera merupakan utama biji-bijian di penyimpanan. Tujuan dari peneltian ini untuk mengetahui efektivitas B. isolat lokal dalam mengendalikan Coleoptera. Penelitian menggunakan Rancangan Acak Lengkap (RAL) faktorial terdiri 12 perlakuan dengan 3 ulangan sehingga terdapat 36 unit percobaan. Hasil penelitian menunjukkan bahwa aplikasi berpengaruh nyata terhadap masa inkubasi, mortalitas, rata-rata waktu kematian Masa inkubasi tercepat imago S. konsentrasi 15g/100ml yaitu 6,67 hari terlama T. castaneaum 5g/100ml 9,00 hari. Mortalitas tertinggi 10g/100ml sebesar 77,5% terendah 56,66% pengamatan 7 HSA. terjadi 84,45% larva 56,66%.

Entomopathogens are microorganisms that have ability to cause disease insects, including viruses, bacteria, fungi, protozoa, and nematodes. One entomopathogenic fungi species has potential as biological agents control insect pests is belong order main stored grain. The purpose this study was determine effectiveness fungus local isolates controlling This used a factorial completely randomized design (CRD) consisting treatments with replications so there were experimental units. results showed application had significant effect on incubation period, mortality, average time death for pests. fastest period concentration 15g / 100ml 6.67 days longest 5g 100ml, namely 9.00 days. highest mortality at 10g 77.5% lowest 56.66% HSA observations. occurred 84.45% larvae 56.66%. mean treatment 3.40 which 4.65 5.07 imago. Thus, effective

In vitro evaluation for compatibility of additives with Beauveria bassiana (Balsamo) Vuillemin

An in vitro evaluation was conducted for compatibility of 12 commonly used additives at three different concentrations of (0.1, 0.5, and 1.00%) with Beauveria bassiana through poisoned food technique. The results were expressed as radial growth and growth inhibition of B. bassiana on an additive treated medium. All the additives showed an inhibition in mycelial growth of B. bassiana, either par...

Susceptibility of preimaginal western cherry fruit fly, Rhagoletis indifferens (Diptera: Tephritidae) to Beauveria bassiana (Balsamo) Vuillemin Clavicipitaceae (Hypocreales).

Last-instar larvae of the western cherry fruit fly, Rhagoletis indifferens, were subjected to Beauveria bassiana GHA incorporated into sterile sand and non-sterile orchard soil. Mycosis in the pupal stage was observed in >20% of buried R. indifferens pupae and >80% of larvae entering sand treated with either of two B. bassiana isolates. When pre-pupal larvae burrowed into conidium-treated non-s...
