| ABSTRACT 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... |

| 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... |

| Blattella germanica (Dictyoptera: Blattellidae) es la especie más importante de las cucarachas sinantrópicas en el mundo. En este trabajo se evaluó la patogenicidad de aislamientos de Metarhizium anisopliae, M. pingshaense y Beauveria bassiana en ninfas y adultos de B. germanica. Para ofrecer una alternativa al uso de insecticidas en el manejo de B germanica, se desarrolló una formulación de cebo en polvo y pellet. Se determinó la preferencia de adultos de esta cucaracha, a diferentes dosis de azúcar glas (0.125, 0.25, 0.5, 0.75M) como fagoestimulante y se evaluó la compatibilidad del ácido bórico con los hongos M anisopliae y B bassiana en estos cebos. Finalmente, se evaluó vía oral, la virulencia de cebos formulados con azúcar glas 0.5 M, ácido bórico... |

| 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),... |

| In order to construct specific primers for the detection and identification of the entomopathogenic fungus Metarhizium within infected sugarcane borer (Diatraea saccharalis) larvae we analyzed the ITS1 -5.8S- ITS2 rDNA regions of strains and varieties of M. anisopliae, M. album and M. flavoviride. The PCR amplification of these regions yielded a unique fragment of approximately 540 bp for M. anisopliae variety anisopliae strains E9, B/Vi and C (isolated in Brazil), 600 pb for M. a. anisopliae strain 14 (isolated in Australia), 650 bp for the M. album and 600 bp for M. flavoviride strains. The PCR products were digested with different restriction endonucleases (Afa I, Alu I, Dde I, Hae III, Hpa II and Sau 3A) and the PCR-RFLP profiles showed clear... |

| 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... |

| Abstract The combination of phytosanitary products (PPs) and entomopathogenic fungi (EF) can be used in integrated pest management (IPM) programs. The aim of the present work was to study the effects of PPs, commonly used in Argentina and Brazil, combined with Beauveria bassiana, Metarhizium anisopliae and Cordyceps (Isaria) fumosorosea, for the control of insect pests in the post-harvest of wheat, under laboratory and semi-field conditions. In vitro compatibility was assessed using the biological index (BI) based on the percentages of fungal vegetative growth, sporulation, and germination. The number of colony-forming units (CFUs) was evaluated under semi-field conditions. In all cases, PPs evaluated reduced the mean germination percentages as compared... |

| Abstract Beauveria bassiana, an entomopathogenic fungus, is the alternative biocontrol agent exploited against major economic crop pests. Pieris brassicae L. is an emerging pest of the Brassicaceae family. Therefore, in the present study, fungal isolates of Beauveria bassiana, viz. MTCC 2028, MTCC 4495, MTCC 6291, and NBAII-11, were evaluated for their virulence against third instar larvae of P. brassicae. Among all these fungal isolates, maximum mortality (86.66%) was recorded in B. bassiana MTCC 4495 at higher concentration of spores (109 conidia/ml), and the minimum mortality (30.00%) was recorded in B. bassiana MTCC 6291 at a lower concentration (107 conidia/ml) after ten days of treatment. The extracellular cuticle-degrading enzyme activities of... |

| Abstract The housefly Musca domestica is a worldwide insect pest that acts as a vector for many pathogenic diseases in both people and animals. The present study was conducted to evaluate the virulence of different local isolates of Beauveria bassiana, Metarhizium anisopliae and Isaria fumosorosea on M. domestica using two bioassay techniques: (1) adult immersion and (2) a bait method applied to both larvae and adults. The results showed evidence of a broad range of responses by both stages (larvae and adults) to the tested isolates of B. bassiana, M. anisopliae and I. fumosorosea. These responses were concentration-dependent, with mortality percentages ranging from 53.00% to 96.00%. Because it resulted in lower LC50 values and a shorter lethal time, B.... |

| ABSTRACT: Asian citrus psyllid, Diaphorina citri, is considered the most important citrus pest worldwide, as it transmits Huanglongbing – serious citrus disease. New efficient and sustainable strategies to control this pest have been investigated and the use of entomopathogenic fungi has become a promising alternative. The objective of this study was to evaluate the effects of adjuvants a) Tween 80 at 0.01 % (v/v); b) Silwet L77 at 0.025 % (v/v) and c) KBRAdj at 0.075 % (v/v) on adhesion, germination and pathogenicity of Isaria fumosorosea ESALQ-1296(5 × 106 conidia mL–1). Female adults of D. citri used in this experiment were sprayed on Citrus limonia seedlings. The sprayed insects were analyzed through scanning electron microscopy (SEM) to identify the... |
