The kudzu bug, Megacopta cribraria (F.), is an urban nuisance and significant agricultural pest. The median lethal concentrations of three strains of Beauveria bassiana (Balsamo), including the Mississippi Delta native strain (NI8) isolated from Lygus lineolaris (Palisot de Beauvois), the commercial strain BotaniGard(®) (GHA) (Victor, NY, USA), and the B. bassiana strain isolated from M. cribra...

The diamondback moth (Plutella xylostella) is a major pest of broccoli crops in Colombia. To control P. xylostella, we evaluated the interaction of Beauveria bassiana Bb9205 and Metarhizium anisopliae Ma9236 with Heterorhabditis bacteriophora HNI0100 and its bacterial symbiont Photorhabdus luminescens HNI0100. We used antagonism and disk diffusion assays with fungal extracts to test the interac...

SILVA, S.B. DA; BITTENCOURT V.R.E.P. [Evaluation of cellular response in engorged females of Boophilus microplus (Canestrini, 1887) inoculated with Metarhizium anisopliae, Beauveria bassiana, Penicillium corylophilum or Fusarium oxysporum]. Avaliação da resposta celular de fêmeas ingurgitadas de Boophilus microplus (Canestrini, 1887) inoculadas com Metarhizium anisopliae, Beauveria bassiana, Pe...

The spotted asparagus beetle, Crioceris quatuordecimpunctata (Coleoptera: Chrysomelidae), is one of the most devastating pests of asparagus in China. Sprayed synthetic pesticides have been used to control C. quatuordecimpunctata damage, but they pose problems because of residues and harm to natural enemies. Neither the microbial coleopteran-specific toxin from Bacillus thuringiensistenebrionis,...

The phylogenetic lineage, taxonomic affiliation and interrelationships of important asexual entomopathogenic fungal genera were studied using the sequences of partial regions of beta-tubulin and rRNA genes. The species structures of Beauveria bassiana and Nomuraea rileyi were also investigated. A total of 147 fungal entries covering 94 species were analysed. Phylogenetic analysis placed all the...

The susceptibility of Agrilus planipennis Fairmaire (Coleoptera: Buprestidae) to selected strains of the entomopathogenic fungi Beauveria bassiana (Balsamo) Vuillemin and Metarhizium anisopliae (Metschnikoff) Sorokin was evaluated through bioassays with direct immersion or foliar exposure under laboratory conditions. Results showed that A. planipennis adults were susceptible to B. bassiana and ...

Beauveria bassiana strain 04/01-Tip, obtained from a larva of the opium poppy stem gall wasp Iraella luteipes (Hymenoptera; Cynipidae), endophytically colonizes opium poppy (Papaver somniferum L.) plants and protects them against this pest. The goal of this study was to monitor the dynamics of endophytic colonization of opium poppy by B. bassiana after the fungus was applied to the seed and to ...

background: chemical control method using different acaricides as spray, dipping solution or pour-on is routinely used for controlling ticks. biological control agents are favorable due to their safety for animals and environment. entomopathogenic fungi such as beauveria bassiana are well known for controlling ticks. in this study, two iranian indigenous strains of b. bassiana ( b. bassiana 519...

de la polimerasa (PCR) y secuenciación mediante amplificación genómica de la región espaciadora interna transcrita (ITS-2) del ADN ribosómico, obteniendo Beauveria bassiana con un porcen-taje de similitud de la misma especie en GenBank del 99% (BLAST GU373855.1). Tras su identificación, y aun no habiendo suficientes pruebas que demostraran la infección fúngica, se decidió tratar al paciente con...

We have established the chemical structure of (+)-bassianolone (3), the antimicrobial compound precursor of cephalosporolides E and F, and that of the furan metabolite 4 from the entomopathogenic fungus Beauveria bassiana.
