The principal objective of this study was to determine the optimal liquid culture conditions in shake flasks for maximal sporulation of Beauveria bassiana. The optimal initial pH for the spore production of B. bassiana using Potato Dextrose Broth was 5.2. The screening in shake flasks of carbon and nitrogen sources resulted in the identification of an optimal medium based on 3% sucrose and 1% c...

The most important pathogenic fungus of the silkworm, Bombyx mori L. (Lepidoptera: Bombycidae), is Beauveria bassiana (Balsamo-Crivelli ) Vuillemin (Hypocreales: Clavicipitaceae), which causes significant damage to sericulture production. Therefore, diagnosing fungal disease and developing new control measures are crucial to silk production. To better understand the responsive and interactive m...

We have analysed the mycobiota of date palm (Phoenix dactylifera, L.) leaves using several techniques. Profusely sporulating fungi (Penicillium spp. and Cladosporium spp.) developed when plating leaf fragments and leaf washings. Fusarium oxysporum, was particularly abundant in leaves infested with the red scale insect Phoenicococcus marlatti Cockerell, 1899, but an undescribed Lecanicillium cf....

Entomopathogenic fungi, such as Metarhizium anisopliae and Beauveria bassiana, are being researched as alternatives to chemical adulticides to control mosquito vectors of malaria and dengue. Two cited concerns of fungal control include conidial viability and risks fungal entomopathogens pose to human health. We measured spore viability of 10 fungal isolates over 26 weeks and found a range of pe...

The direct toxicity of insecticidal soap, horticultural oil, Azatin, an extract from the Neem tree containing azadiractin, and BotainiGard, a commercial formulation of the entomopathogenic fungus Beauveria bassiana, was assessed on adults of four species of coccinellids--Hippodamia convergens (Guérin-Ménéville), Coleomegilla maculata (DeGeer), Harmonia axyridis Pallas, and Cryptolaemus montrouz...

Tanaman jagung merupakan salah satu tanaman pangan yang biasa dikonsumsi masyarakat Indonesia. Kerusakan akibat serangan Spodoptera litura pada mencapai 85% bahkan dapat menyebabkan gagal panen. Salah upaya untuk mengendalikan ialah menggunakan entomopatogen Beauvaria bassiana. Tujuan penelitian ini adalah mengetahui pengaruh aplikasi bassiana (Bals.) Vuil. terhadap mortalitas dan intensitas li...

We investigated the fungal entomopathogens Beauveria bassiana and Metarhizium anisopliae to determine if endophytic colonization could be achieved in cassava. An inoculation method based on drenching the soil around cassava stem cuttings using conidial suspensions resulted in endophytic colonization of cassava roots by both entomopathogens, though neither was found in the leaves or stems of the...
