Tigano,Myrian S.; Adams,Byron; Maimala,Saowanit; Boucias,Drion. Amplified fragment length polymorphism (AFLP) was used to investigate polymorphism among 43 Hirsutella thompsonii isolates (33 from Thailand) obtained from various mite species. The outgroups were an unidentified Hirsutella isolate along with Hirsutella nodulosa and Hirsutella kirchneri. Phylogenetic analyses of the AFLP data showed significant variation among isolates and the existence of three H. thompsonii clades. We also investigated the isolates using PCR with specific primers for the Hirsutella exotoxin gene Hirsutelin A (HtA) and 18 of these isolates were used for sequencing of the partial beta-tubulin gene. Phylogenetic analyses of beta-tubulin sequences showed two distinct H. thompsonii clades, one of which included AFLP clades I and II. For both...

In vitro development - radial growth and sporulation - of Nomuraea rileyi isolates from Anticarsia gemmatalis Hübner and Plusiinae larvae was studied on four culture media: Sabouraud, maltose, agar and yeast - SMAY; SMAY plus rice extract - SMAYR; complete medium for N. rileyi - CMNr and maltose agar yeast with potato extract - MAYP. Their development on a selected medium (MAYP) was analysed at five temperatures. Two mathematical models were fitted to in vitro and in vivo temperature dependent radial growth rates and thermal requirements were estimated. The medium with potato and yeast extract induced the highest growth rate in most cases, while SMAY induced the lowest rates for the tested isolates. Estimated optimum temperatures for mycelium in vitro... Tipo: Info:eu-repo/semantics/article Palavras-chave: Entomopathogenic fungus; Radial growth; Mathematical model; Biological control.

A bioassay method that uses melon leaves as substrate for eggs and nymphs of the biotype B of Bemisia tabaci (Genn.) was established. Root formation of petioles immersed in tap water guaranteed the turgidity and normal coloration of leaves for a period of 20 to 25 days, enabling the execution of tests with entomopathogenic fungi. The virulence of 50 isolates of Beauveria bassiana (Balsamo) Vuillemin was assessed, as an initial action of a research project that aims the development of a bioinsecticide for controlling Bemisia tabaci nymphs in melon crops. Melon leaves were infested with 18 couples of biotype B adults for 26 hours. First-instar nymphs were selected through microscopic observation approximately 4-5 days after adults removal.

(Diptera: Muscidae) treated with two strains of Beauveria bassiana (Bals.) Vuil. (Deuteromycetes) Neotropical Entomology Lecuona,Roberto; Crespo,Diana; La Rossa,Francisco. The parasitoid Spalangia endius Walker is an efficient controller of Dipteran pupae, such as Musca domestica L. The entomopathogenic fungus Beauveria bassiana (Bals.) Vuil. is a regulator of insect populations, including these synanthropic pests. The aim of this work was to explore the possibilities of utilizing both agents in a combined form for the biocontrol of the domestic fly. Recently formed M. domestica pupae were inoculated by immersion in conidia suspension (10(8) conidia/ml) with two strains of B. bassiana (Bb6 and Bb10). The inoculated pupae were offered to the female parasitoid. In one bioassay they were offered pupae inoculated a single day and in other, pupae inoculated the following day as well. In both bioassays non inoculated (control)... Tipo: Info:eu-repo/semantics/article Palavras-chave: Entomopathogenic fungus; Biological control.

Vuillemin Neotropical Entomology DIEHL,ELENA; JUNQUEIRA,LUCIANE K.. Mechanisms involved in maintaining colonies of social insects free of pathogens are among the main aspects of interest in the evolutionary biology of this group. For ants, it has been suggested that secretion from the metapleural glands play an important role in colony asepsis. In this study, different worker subcastes of the fungus-growing ant Atta sexdens piriventris Santschi were compared in relation to presence of metapleural secretion during a year. At the same time, the topical activity of the secretion was tested on workers treated with the entomopathogenic fungus Beauveria bassiana (Bals.) Vuillemin. Based on the mean width of the cephalic capsule, six worker subcastes were defined: gardener, minor, media, large, major and soldier. A positive...

The present study aimed to analyze the action of some acaricides, fungicides, insecticides and herbicides containing different active ingredients on Metarhizium anisopliae Metsch. (Sorokin) inoculated into autoclaved soil. The action of the pesticides was evaluated based on the fungal respiratory activity. The first assessment was done at 48h after inoculation. The pesticides were then added and respiratory activity was determined nine times every 48h and an additional five times every 4 days. Except for the fungicides, no significant effect (P > 0.05) of the pesticides on M. anisopliae was observed. A reduction in CO2 production was observed for the mancozeb treatment from day 4 to day 6 of incubation, and for tebuconazol between days 4 and 6, 8 and...

Microbiol. Braga,Gilberto U.L.; Destéfano,Ricardo H.R.; Messias,Claudio L.. The growth and autolysis of two strains of the entomopathogenic deuteromycete fungus Metarhizium anisopliae var. anisopliae were evaluated in medium containing casein or glucose as carbon source. Parameters such as economic coefficient and degree of autolysis were determined for each strain. Protease production was determined throughout the growth and autolysis phases of the cultures on medium under conditions of protease induction (in the presence of casein as sole source of carbon and nitrogen). The fungus was shown to utilize casein as a carbon/energy source in a more efficient manner than glucose. The autolysis shown by the strains was intense under both types of growth conditions, reaching up to 62.7% of the dry mass produced and started soon after...

Xavier-Santos,Solange; Magalhães,Bonifácio; Lima,Elza A. Luna-Alves. The differentiation of a Brazilian isolate of Metarhizium flavoviride (CG 423), a promising candidate for the biocontrol of grasshoppers, was investigated. Conidia were spread onto solid medium (1% yeast extract, 2.8% agar, 96.2% distilled water), incubated at 28°C and observed during 26 h. Germination initiated as conidia size increased from 5.3 (±0.6) x 3.1 (±0.3) µm (0 h incubation) to 8.1 (±0.2) x 6.1 (±0.2) µm (8 h incubation). Germ tubes started to appear after 10 h incubation showing a high degree of multipolarity. Twenty six hours after inoculation, hyphal differentiation and anastomosis among hyphae from adjacent conidia were recorded. Appressoria were formed only from conidia incubated in liquid medium containing minimum concentration of yeast...

The cotton leafworm, Alabama argillacea (Huebner, 1818) (Lepidoptera: Noctuidae), is considered to be one of the key pests in herbaceous cotton (Gossypium hirsutum L. r. latifolium Hutch) cropping, with constant occurrence in all cotton-growing states of Brazil. In this study Metarhizium anisopliae and Beauveria bassiana isolates were screened and evaluated for pathogenicity against Alabama argillaceae. Initially, a screening of ten isolates of each fungus in a concentracion of 10(8) conidia mL-1, was carried out on 3rd instar larvae of A. argillacea. Further studies were conducted to determine the pathogenicity and virulence of six and seven isolates of M. anisopliae and B. bassiana, respectively, against 3rd instar larvae of A. argillacea and using the...

Chinch bugs of the genus Blissus (Hemiptera: Lygaeidae) are serious pests of maize, wheat, sorghum and various grasses. This study is the first to screen isolates of Beauveria bassiana and Metarhizium anisopliae against 4th instar and adult Blissus antillus aiming to develop a biological control program for this important pasture pest. Ten fungal isolates were initially screened and three isolates were chosen for further investigation. To determine virulence, insects were inoculated by immersion in concentrations of 5 ´ 10(8) conidia mL-1. Mortality was evaluated for 10 days. B. bassiana ARSEF 792 was the most virulent isolate to both nymphs and adults, causing 53 and 78% infection, respectively, and values for LT50 of 7.8 and 5.0 days, respectively....

ITS and RAPD analyses were used to investigate molecular variations within samples of Paecilomyces isolates and to resolve five morphologically atypical isolates resembling P. fumosorosus, obtained from whitefly in Northern Paraná State. The ITS4-ITS5 amplicon was 700 base pairs (bp) long in all isolates. The five isolates of Paecilomyces not assigned to species produced restriction profiles identical to all the reference strains of P. fumosoroseus. The extent of fingerprint variability observed by RAPD was sufficient to discriminate all the isolates. The genetic similarity among unidentified isolates and strains of P. fumosoroseus was even higher than that observed among reference strains of this species, allowing us to conclude that isolates CNPso-P77,...

This study investigated whether populations of naturally-occurring soil bacteria, fungi and actinomycetes influence the effect of fungicides on the survival and growth of Beauveria bassiana. The toxicity of methyl thiophanate, pyraclostrobin, mancozeb and copper oxychloride at the recommended doses was analyzed in culture medium and in soil inoculated with fungus at various time points after addition of fungicides. All fungicides completely inhibited the growth and sporulation of B. bassiana in the culture medium. The fungicides were less toxic in soil, emphasizing the action of the microbial populations, which interfered with the toxic effects of these products to the fungus. Actinomycetes had the greatest influence on the entomopathogen, inhibiting it or...
