Taxonomic notes on the Zethus olmecus de Saussure, 1875 species group (Hymenoptera, Vespidae, Eumeninae), with the description of five new species.

Zethus Fabricius is the largest genus within Vespidae with nearly 300 species. The genus has a central role on discussion of social evolution, once some species share behavioral features between solitary and social representatives of vespids and the genus has been recovered as phylogenetically closer to social wasps than to other Eumeninae. The Zethus olmecus species group is even more remarkable since there are observations of communal nesting behavior, a fact misused as support for the hypothesis of closer relationship to social wasps.

A new species of Huarpea Pate, 1947 (Hymenoptera, Sapygidae) from the semiarid region of Brazil.

The genus Huarpea is recorded for the first time in northeastern Brazil. A new species, H. rotundicornis Lopes, Moleiro & Lucena, sp.

Impact of the use of active methodology on the performance of undergraduate radiology students.

Rationale And Objectives: Although PBL is widely used in several countries, especially in medicine courses, its application in teaching other higher education courses, which involve fundamentals applied to radiology, is still little explored. Therefore, we aim to evaluate the implementation of Problem-Based Learning (PBL) in a higher education institution's radiology and biomedicine technologist course, focusing on specific radiology-related disciplines.

Materials And Methods: An interventional study was developed with 78 students.

Diversity of anamorphic Cordyceps (formerly Isaria) isolated from Brazilian agricultural sites.

A total of 53 anamorphic strains of Brazilian Cordyceps species currently maintained in a government-owned culture collection, were reassessed for diversity and species identity using multi-loci-based phylogenetic methods. The strains used in this study were originally obtained from soil samples or were isolated from insects of the orders Hemiptera, Lepidoptera, Coleoptera and Diptera, mostly from agricultural sites. A Bayesian phylogenetic tree was constructed based on a concatenation of five loci (ITS, LSU, RPB1, RPB2 and TEF).

On-farm Production of Microbial Entomopathogens for use in Agriculture: Brazil as a Case Study.

In Brazil, the production of beneficial microorganisms by growers exclusively for their own use is a practice known as "on-farm production". Regarding on-farm bioinsecticides, they were initially deployed for pests of perennial and semi-perennial crops in the 1970s but, since 2013, their use has extended to pests of annual crops such as maize, cotton, and soybean. Millions of hectares are currently being treated with these on-farm preparations.

Potential Impact of Chemical Fungicides on the Efficacy of Metarhizium rileyi and the Occurrence of Pandora gammae on Caterpillars in Soybean Crops.

Entomopathogenic fungi may play a crucial role in the regulation of caterpillar populations in soybean crops, either through natural occurrences or applied as mycopesticides. In the present work, we reported the naturally occurring entomopathogenic fungus Pandora gammae attacking the caterpillar Chrysodeixis includens, with infection rates in field trials ran in two consecutive years in the 10-35% range. As many chemicals are potentially harmful to entomopathogenic fungi, this work aimed to investigate the potential impact of two chemical fungicides (azoxystrobin + benzovindiflupyr and trifloxistrobina + prothioconazole) used to control soybean rust (Phakopsora pachyrhizi) on the natural occurrence of P.

Natural occurrence of Beauveria caledonica, pathogenicity to Cosmopolites sordidus and antifungal activity against Fusarium oxysporum f. sp. cubense.

Background: Entomopathogenic fungi can provide a set of ecological services, such as suppressing arthropod pests and plant pathogens. In this study, novel indigenous Beauveria caledonica (Bc) strains were isolated from naturally infected banana weevils (Cosmopolites sordidus) occurring in commercial banana plantations in Brazil.

Results: The prevalence of infection by Bc strains on field-caught C.

Associations between muscle mass, strength, and performance and non-alcoholic fatty liver disease.

Background: Non-alcoholic fatty liver disease (NAFLD) is a rising global health issue. The influence of muscle in its pathophysiology has recently gained attention. Our aim was to investigate the association of low muscle mass, strength, and performance with the presence and severity of NAFLD.

A Comprehensive Review of the Coffee Leaf Miner (Lepidoptera: Lyonetiidae)-A Major Pest for the Coffee Crop in Brazil and Others Neotropical Countries.

The coffee leaf miner (CLM) moth is a major threat to coffee production. Insect damage is related to the feeding behavior of the larvae on the leaf. During the immature life stages, the insect feeds in the mesophyll triggering necrosis and causing loss of photosynthetic capacity, defoliation and significant yield loss to coffee crops.

Evaluation of key parameters for developing a Metarhizium rileyi-based biopesticide against Spodoptera frugiperda (Lepidoptera: Noctuidae) in maize: laboratory, greenhouse, and field trials.

Background: The entomopathogenic fungus Metarhizium rileyi is known to cause natural infections in some caterpillars. In this multiyear study, we carried out laboratory, greenhouse and three field trials with the aim of developing a sustainable option for control of the fall armyworm (FAW) in maize. Association of M.

First report on the natural occurrence of entomopathogenic fungi in populations of the leafhopper Dalbulus maidis (Hemiptera: Cicadellidae): Pathogen identifications and their incidence in maize crops.

The corn leafhopper Dalbulus maidis is one of the most important pests of maize in Latin America. Here we report, for the first time, the natural occurrence of two fungal species infecting the adult stage of this pest. In 2020, insects killed by a pale bluish green fungus in irrigated maize fields located in Northeast Brazil were found attached to the abaxial surface of leaves.

Field Efficacy of Metarhizium rileyi Applications Against Spodoptera frugiperda (Lepidoptera: Noctuidae) in Maize.

The efficacy of the fungus Metarhizium rileyi (Farlow) Kepler, S. A. Rehner & Humber (Hypocreales: Clavicipitaceae) against the fall armyworm Spodoptera frugiperda (J.

Increasing Anthonomus grandis susceptibility to Metarhizium anisopliae through RNAi-induced AgraRelish knockdown: a perspective to combine biocontrol and biotechnology.

Background: The hemolymph and insect gut together have an essential role in the immune defense against microorganisms, including the production of antimicrobial peptides (AMP). AMPs are mainly induced by two specific signaling pathways, Toll and immune deficiency (IMD). Here, we characterize the expression profile of four genes from both pathways and describe the importance of AgraRelish in the immune defense of Anthonomus grandis against the entomopathogenic fungus Metarhizium anisopliae by RNA interference (RNAi).

Notes on Zethini (Hymenoptera, Vespidae, Eumeninae): complementary sex descriptions, synonymies and a new species of Zethus Fabricius.

This paper brings a series of contributions to the taxonomy of the Zethini: description of a new species, Zethus denticlypeus Lopes, sp. n.; description of the female of Z.

Taxonomic revision and cladistic analysis of the species of Zethus mexicanus group (Linnaeus, 1758) sensu Bohart amp; Stange, 1965 (Hymenoptera, Vespidae, Eumeninae).

The Zethus mexicanus group sensu Bohart Stange (1965) consists of four species in the subgenus Zethusculus: Zethus brasiliensis de Saussure, 1852, Z. mexicanus (Linnaeus, 1758) (both subdivided into three subspecies each), Z. magnus de Saussure, 1852 and Z.

Assessment of the diversity of Brazilian entomopathogenic fungi in the genus Beauveria.

We combined matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) along with sequencing of the B locus intergenic region (Bloc) to assess the diversity of Brazilian species within the anamorphic genus Beauveria. A total of 121 strains maintained in a government-owned culture collection and isolated from a range of hosts/substrates over a long time span (1981-2015) were assessed. Strains were collected in five of six Brazilian biomes, mostly in the Atlantic Forest (42.

Laboratory and field evaluation of an autoinoculation device as a tool to manage poultry red mite, Dermanyssus gallinae, infestations with Beauveria bassiana.

The poultry red mite, Dermanyssus gallinae, is a cosmopolitan ectoparasite in hens and has been considered an important threat to the egg production industry. This study evaluated an alternative to manage poultry red mite populations as a complement to conventional chemical treatments and other control strategies in poultry houses. A simple autoinoculation device prepared with corrugated cardboard (CB) or loofah sponge (LS) as inert supports to anchor Beauveria bassiana conidia was used to aggregate and infect mites from infested poultry houses.

Zethus (Zethus) pilosus Zavattari, 1912 (Hymenoptera: Vespidae: Eumeninae) from Southern Brazil: description of the female, the male genitalia, its nest and notes on biology.

Zethus is the largest vespid genus and, despite being very diverse in the Neotropical region, little is known about its biology and many species are known from only one sex. Zethini are centered in one of the controversies involving Vespidae phylogeny; increased knowledge of terminals will allow for more precise analyses, because some phylogenetically informative characters are observed in only one sex and others can be extracted from nests. With this in mind, complementary knowledge on Zethus pilosus is presented: the description of the female, of the male genitalia, of the nest and notes in its biology.

Metarhizium humberi sp. nov. (Hypocreales: Clavicipitaceae), a new member of the PARB clade in the Metarhizium anisopliae complex from Latin America.

Within-host interactions of Metarhizium rileyi strains and nucleopolyhedroviruses in Spodoptera frugiperda and Anticarsia gemmatalis (Lepidoptera: Noctuidae).

Members of the family Baculoviridae have been quite successfully used as biocontrol agents against some lepidopterans. Likewise, a number of fungi are important natural enemies of these pests. An interesting approach to increase control efficacy could be the combination of a given nucleopolyhedrovirus (NPV) and a fungus, since they possess distinct modes of action.
