Field tests were carried out during the rainy season of 2001/2002 in São Luís de Montes Belos, Goiás, Brazil, to evaluate the potential of the entomopathogenic fungus, Beauveria bassiana, against peridomestic Triatoma sordida. An oil-water formulation of the isolate CG 14 (Embrapa) was applied in triatomine infested hen houses of four farms at a final concentration of 10(6) conidia/cm2. Numbers...

The sweetpotato whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) continues to be a serious threat to crops worldwide. The UK holds Protected Zone status against this pest and, as a result, B. tabaci entering on plant material is subjected to a policy of eradication. Both B and Q Bemisia biotypes are now regularly intercepted entering the UK. With increasing reports of neonicotinoid ...

Laboratory experiments on the evaluation of infectivity of Beauveria bassiana (Bals.) Vuill. to tobacco caterpillar Spodoptera litura Fab. as influenced by two okra varieties. Infectivity of B. bassiana at three concentrations viz. 0.1, 1.0 and 3.0 per cent was evaluated by contaminated food bioassay method. In comparison, topical bioassay method was also made. Statistically significant variati...

Sanitation being an important component of chemical-free management of stored-products pests, the nutritional stress on insects that results from a clean environment may prove advantageous to the use of microbial controls. Dietary stress by food deprivation or suboptimal diet increased susceptibility of the red flour beetle, Tribolium castaneum (Herbst), larvae to Beauveria bassiana (Balsamo) V...

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...

The entomopathogenic fungus Beauveria bassiana was re-isolated from surface sterilized pieces of the cocoa pod outer section and peduncle, two and three months after flowers of greenhouse cocoa plants were hand-pollinated and sprayed with a 1x107 mL-1 suspension of B. bassiana conidia. The colonization frequency of B. bassiana on cocoa pods was 0.8% and 1.3% two and three months post-spraying o...

Abstract This research aimed to determine the Beauveria bassiana entomopathogen fungus as a biofertilizer and biostimulant. The was conducted at Biological Control laboratory Wire House, Universitas Andalas. potency of B. produced IAA hormone carried out by qualitative observing pink color change in Salkowsky solution while dissolve phosphate using Pikovskaya medium. test results on media showe...

High chili production is inseparable from proper fertilization and control of pests plant diseases. This done because red a that quite susceptible to attack by diseases, resulting in disruption growth decreased chili. Efforts can be made overcome this problem are applying biofertilizer entomopathogenic fungi (Beauveria bassiana) as biological agents. The application expected increase the plants...

A chemical toxicity and teratogenicity test was adapted to assess potential adverse effects of a microbial pest control agent on a nontarget fish. Developing embryos of the inland silverside, Menidia beryllina, were exposed to conidiospores of the insect-pathogenic fungus Beauveria bassiana. Embryo rupture and death were observed. Embryo rupture did not always result in death, nor was death alw...
