Since 2016, the fall armyworm (FAW) Spodoptera frugiperda has spread over extensive areas of tropics and subtropics, imperiling food security, economic progress livelihoods millions cereal farmers. Although FAW received long-standing scientific attention in its home range Americas, chemical inputs feature prominently mitigation biological control uptake is globally lagging. Here, building upon a quantitative review global literature, we methodically dissect science. Of known entomopathogens...
Abstract Brazil and China have been successful in the use of microbial control methods to manage several agricultural forest insects. In both countries, entomopathogenic fungi (EF) used for pest management since 1970s. However, EF production commercialization not constant either country. Several companies cooperatives suspended their activities or shut down from 1970s 1990s. This was due loss confidence available mycoinsecticides by Brazilian farmers reduced involvement government subsidies...
Abstract Meloidogyne enterolobii is one of the most important root-knot nematode in tropical regions, due to its ability overcome resistance mechanisms a number host plants. The lack new and safe active ingredients against this has restricted control alternatives for growers. Egg-parasitic fungi have been considered as potential candidates development bionematicides. In tissue culture plates, Pochonia chlamydosporia (var. catenulata chlamydosporia) Purpureocillium lilacinum strains were...
A new species, Metarhizium humberi, from the M. anisopliae complex and sister lineage of s.str. in PARB clade, including pingshaense, anisopliae, robertsii brunneum, is described based on phylogenetic analyses [translation elongation factor 1-alpha (5'TEF 3'TEF), RNA polymerase II largest subunit (RPB1a), second (RPB2a) β-tubulin (BTUB)]. humberi was first collected 2001 Central Brazilian state Goiás, later found to be a common fungus soils Brazil, since then has also been isolated...
This work investigated the production of fungi Isaria fumosorosea and farinosa in biphasic fermentation using agro-industrial products residues. Combinations natural liquid substrates, alternative to complete medium potato dextrose medium, were evaluated. The best media sugarcane molasses + rice broth, broth yeast which resulted highest viable propagule concentration. was selected for next phase study both fungal isolates evaluated solid grain substrates. In solid-state fermentation, conidia...
Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) has proven to be a powerful tool for taxonomic resolution of microorganisms. In this proof-of-concept study, we assessed the effectiveness technique track current gene sequence-based phylogenetic classification species in Metarhizium anisopliae complex. Initially analysis 5′ strains by sequencing 59′ end TEF-1α region revealed seven within M. sensu lato and two varieties outside Because initial...
The substantial negative impact of some parameters on the germination low-quality conidia (high proportion slow-germinating propagules) was demonstrated, whereas for high-quality batches their effect small or even absent. Germination increased as initial hydration status immediately prior to suspension preparation increased, being ca. 33% and 80% dehydrated Metarhizium anisopliae propagules (water activity ≤0.314) from low- after an 18 h incubation period, respectively, 63% 95% hydrated =...
The formulation of mycopesticides may require a physical separation conidia from the substrate and subsequent drying. In present study, Beauveria bassiana produced by solid-state fermentation were harvested either through dry or washing protocol. Washed used to design water-dispersible granule (WG) formulation, whereas sieved mixed with an emulsifiable oil achieve oil-based (OD). Potential harmful effects caused type on storage stability insecticidal activity against Hypothenemus hampei...
Abstract: The potential of some isolates Metarhizium anisopliae and Beauveria bassiana for use in the integrated management Culex quinquefasciatus was evaluated. isolate 1037 selected initial bioassays with a 50% lethal concentration (LC 50 ) 1.97 × 10 4 conidia/ml. This fungus caused higher mosquito larva mortality when applied as conidial suspension to surface water than dry conidia, time (LT 1 day compared 3.6 days application. However, results UV‐ heat‐inactivated conidia did not confirm...
Abstract We evaluated the protection afforded by an oil formulation against non-compatible fungicides in mixtures with conidia of entomopathogenic fungi Metarhizium anisopliae (Ma) and Beauveria bassiana (Bb). Under laboratory conditions, viability unformulated (aqueous suspensions) Ma was harmed recommended label doses carbendazim (not tested for Bb), both Bb were affected triadimefon. On other hand, effect usually nil or minimal on formulated as oil-containing suspensions (emulsifiable +...
