Amazonian isolates of Metarhizium are effective for killing Bactrocera carambolae (Diptera: Tephritidae) Repositório Alice
BRITO, B. D.; LIMA, A. L.; CRUZ, K. R.; BARIANI, A.; JESUS-BARROS, C. R. de; PEREIRA, J. F.; ADAIME, R..
Bactrocera carambolae Drew & Hancock is a quarantine pest present in Brazil and is the main phytosanitary barrier for the export of fresh fruits from that country. In this work, we evaluated the effect of Amazonian isolates of Metarhizium on kill larvae, pupae, and adults of B. carambolae in soil applications. The mortality of larvae and pupae in sterile soil treated with Metarhizium anisopliae was 70 %. In addition, 100 % of the adults that emerged from this substrate died up to five days later. This isolate caused the mortality of larvae and pupae in non-sterile soil, but its effect was more evident after adult emergence (70 % mortality up to ten days after emergence). Metarhizium robertsii was effective in killing larvae and pupae of the pest,...

Alves,LFA; Oliveira,DGP; Lambkin,T; Bonini,AK; Alves,V; Pinto,FGS; Scur,MC.
ABSTRACT Beauveria bassiana is naturally found in broiler chicken houses, and has been shown to be active against the lesser mealworm, Alphitobius diaperinus. The effectiveness of soil application of B. bassiana in emulsifiable oil-type formulation (Unioeste 4 isolate) to control the lesser mealworm in commercial poultry house was evaluated. The fungus was applied to the dirt floor of poultry house at 4.2 × 109 conidia/m2 (treated aviary) and the insect population was assessed before and 96, 146 and 216 days after application (DAA). In the control aviary, no treatment was performed to control those insects. Molecular techniques were used to confirm the presence of the fungus in dead A. diaperinus. Significant treatment effects were observed, with 56% and...

Biological potential of fungi associated to Prays oleae in Trás-os-Montes (Northeastern region of Portugal) IPB - Escola Superior Agrária
Oliveira, Ivo; Baptista, Paula; Lino-Neto, Teresa; Bento, Albino; Pereira, J.A..
Olive groves represent an important fraction of the agricultural practices in Portugal, mainly in the region of Trás-os-Montes. Our work pretends to disclose the fungal diversity associated to one of the major olives pests, the Prays oleae Bern. Besides evaluating the extent of the presence of entomopathogenic fungi, we also intend to reveal other promising fungi with potential to be used as biological control agents. In order to achieve this goal, larvae and pupae of the three generations of P.oleae were collected from several orchards. Whenever a fungal agent was associated to the cause of death, we proceeded to the preparation of fungal pure cultures, DNA isolation, amplification and sequencing of their ITS region for species identification. High fungal...

Comparative virulence of blastospores and conidia of Beauveria bassiana and Cordyceps fumosorosea against soybean pests. Repositório Alice
CORRÊA, B.; DUARTE, V. S.; SILVA, D. M.; MASCARIN, G. M.; DELALIBERA JUNIOR, I..
Entomopathogenic fungi are biocontrol agents capable to infect many insect pests and can produce different infection propagules in artificial media. The soybean crop suffers with attack of many pests and an ideal option would be the use of a single fungal species for the control of a broad host range of this crop. This study aimed to compare the virulence of conidia and blastospores (fresh or air dried) of Beauveria bassiana (Bals.) Vuill. and Cordyceps fumosorosea (Wize) Kepler (Cordycipitaceae) against Bemisia tabaci (Gennadius) biotype B (Aleyrodidae), Chrysodeixis includens (Walker) and Spodoptera frugiperda (JE Smith) (Noctuidae). Two isolates of each fungal species were selected and their conidia and blastospores were obtained by solid and liquid...

Compatibility of conventional agrochemicals used in rice crops with the entomopathogenic fungus Metarhizium anisopliae Scientia Agricola
Silva,Rodrigo Alves da; Quintela,Eliane Dias; Mascarin,Gabriel Moura; Barrigossi,José Alexandre Freitas; Lião,Luciano Moraes.
The toxicological impact of chemical pesticides on fungal entomopathogens and their use in tank-mixing can be directly measured through in vitro compatibility tests. This study reports the in vitro toxicity of eight insecticides, four fungicides and five herbicides in the conidial germination, vegetative growth and conidiation of Metarhizium anisopliae (strain CG 168). A conidial suspension containing the pesticide at recommended field dosage was subjected to constant agitation in a rotary shaker for 3h to simulate a tank mixing. Then, aliquots of each suspension were used to determine conidial germination, vegetative growth and conidiation on potato dextrose agar (PDA). The fungicides difenoconazole (69 mL ha-1), propiconazole (75 mL ha-1),...

Crescimento e esporulação de isolados de Verticillium lecanii sob diferentes fatores ambientais. Repositório Alice
MONTEIRO, A.C.; BARBOSA, C.C.; CORREIA, A. do C.B.; PEREIRA, G.T..
O objetivo deste trabalho foi avaliar o crescimento e a esporulação de dois isolados (JAB 02 e JAB 45) de Verticillium lecanii (Zimm.) Viégas, submetidos a diferentes valores de pH (4, 5, 6, 7, 8, 9) inicial do meio de cultivo sólido, de temperatura (19, 22, 25, 28 e 31oC) e fotoperíodo (0, 12 e 24 horas). Após 20 dias de cultivo, não se observou efeito do pH inicial do meio no crescimento e esporulação dos isolados, exceto no pH 4,0 que reduziu o crescimento. A ausência de iluminação proporcionou a melhor condição para o crescimento de JAB 02 (32,70 mm) e JAB 45 (32,67 mm). Não houve efeito do fotoperíodo na produção de esporos. As melhores temperaturas para o crescimento de JAB 02 foram 19, 22 e 25oC e para JAB 45 foram 19 e 25oC. Este último isolado...

Culture media selection for mass production of Isaria fumosorosea and Isaria farinosa BABT
Mascarin,Gabriel Moura; Alves,Sérgio Batista; Lopes,Rogério Biaggioni.
This work investigated the production of the fungi Isaria fumosorosea and Isaria farinosa in biphasic fermentation using agro-industrial products and residues. Combinations of natural liquid substrates, alternative to the complete medium and potato dextrose medium, were evaluated. The best liquid media were sugarcane molasses + rice broth, rice broth + yeast and sugarcane molasses + yeast + rice broth, which resulted in the highest viable propagule concentration. The molasses + rice broth medium was selected for the next phase of the study in which the production of both fungal isolates was evaluated in solid grain substrates. In solid-state fermentation, the best conidia production was achieved with the soybean meal and broken corn for I. farinosa, and...

Differential susceptibility of adults and nymphs of Blattella germanica (L.) (Blattodea: Blattellidae) to infection by Metarhizium anisopliae and assessment of delivery strategies Neotropical Entomology
Lopes,RB; Alves,SB.
Microbial insecticides for cockroach control, such as those containing entomopathogenic fungi, may be an alternative to reduce contamination by chemicals in housing and food storage environments. Virulence of isolate ESALQ1037 belonging to the Metarhizium anisopliae complex against nymphs and adults of Blattella germanica (L.), and its infectivity following exposure of insects to a contaminated surface or to M. anisopliae-bait were determined under laboratory conditions. Estimated LD50 15 d following topical inoculation was 2.69 x 10(5) conidia per adult, whereas for nymphs the maximum mortality was lower than 50%. Baits amended with M. anisopliae conidia had no repellent effect on targets; adult mortality was inferior to 25%, and nymphs were not...
