“…An important aspect of insect biology that allows these organisms to increase their diversity and abundance is the symbiotic relationships they share with microorganisms that impact directly on their life history traits. Although many of these microorganisms may be commensalist or parasitic (Poveda-Arias, 2019), others play an important role in the nutrition, metabolism and immune protection of their hosts (Dillon and Dillon, 2004;Brune, 2010;Koch and Schmid-Hempel, 2011;Engel and Moran, 2013). Early studies in the Mexican fruit fly, Anastrepha ludens (Loew) were carried out to evaluate resistance or sensitivity to a variety of antibiotics in bacteria isolated from this same species (Kuzina et al, 2001) and to test the attractive effect of metabolites produced by bacteria on A. ludens (Martínez et al, 1994).…”

The West Indian fruit fly, Anastrepha obliqua (Macquart), is the second most important tephritid fruit fly in Mexico, infesting mango, hog plum and guava fruits. To control this pest, the Mexican government has implemented the use of the sterile insect technique (SIT), which involves the mass production, sterilization and release of flies. However, the A. obliqua laboratory males used in SIT are selected to a lesser extent by the wild females during competitiveness tests. The objective of this study was to compare the effects of males fed on fruit fly food enriched with Providencia rettgeri to those in males fed on food alone, assessing male mating competitiveness, capture of females using traps baited with males fed with the enriched diet and sex pheromone components. The results indicated that males fed with the diet enriched with P. rettgeri had increased mating competitiveness and captured more females in the field cage tests. However, no difference was observed in the proportion of volatile sex pheromone components identified during the calling of A. obliqua males. The results suggest the value of incorporating bacteria into the mass rearing technique of A. obliqua adults in order to improve the sexual competitiveness of males from the laboratory compared to wild males.

“…Las asociaciones simbióticas entre plantas, insectos y microorganismos les ha permitido coexistir en los últimos 400 millones de años (Poveda-Arias, 2019). Entre las interacciones microorganismos-Special Issue: Covid-19 and Plant Health, November, 2021 Mexican Journal of PHYTOPATHOLOGY Revista Mexicana de FITOPATOLOGÍA the past 400 million years (Poveda-Arias, 2019). Some of the microorganism-plant interactions worth highlighting are endophytic microorganisms, which live inside plants without causing any harm to them; other microorganisms can live in the rhizosphere (soil around the root), rhizoplane (on the root) and the phylosphere (on the leaf) (Sharma et al, 2019).…”

“…Therefore, gathering information on crop management is crucial to apply and improve biological control and obtain other benefits from organisms with endophytic abilities. We may have to consider gene modification and expression (epigenetic) induced by endosymbionts, as well as its impact in the holobiom microorganisms-insects-plant (Chitnis et al, 2020;Poveda, 2019;Sugio et al, 2015). For example, the bacteria that live intracellularly in aphids, inside cells called bacteriocytes, lose a large portion of their genome (Espinosa, 2019).…”

“…Por consiguiente, recabar información de manejo del cultivo es crucial, para aplicar y mejorar el control biológico y obtener otros beneficios de organismos con capacidad endófita. Habrá que tomar en cuenta la modificación de genes y su expresión (epigenética) inducida por endosimbiontes, así como su impacto entre el holobioma microorganismos-insectos-planta (Chitnis et al, 2020;Poveda, 2019;Sugio et al, 2015); por ejemplo, las bacterias que viven intracelularmente en los pulgones, dentro de células llamadas bacteriocitos, pierden gran parte de su genoma (Espinosa, 2019). En los cultivos de arroz, chícharo, frijol gandú, garbanzo, maíz, soya, tomate y trigo se han encontrado más de 100 géneros de hongos endófitos benéficos.…”

<p>A population with an adequate immunity is key to reduce the effects of COVID-19. Moreover, a healthy diet and an innocuous environment are factors for an adequate immunity. Healthier and more innocuous foods could be obtained with the extensive use of beneficial organisms on agricultural crops, helping reduce the use of agrochemicals and increasing the tolerance of plants to stress caused by abiotic and biotic factors. Nitrogen-fixating bacteria or free-living bacteria, mycorrhizae, endosymbiotic microorganisms, endophytes, entomopathogenic fungi and bacteria, pest predators and parasitoids, hyper parasitic viruses of pests and pathogens are some of the organisms that can induce the natural suppression of parasites, fixate nitrogen and optimize the capture of nutrients and water, among other ecosystemic benefits. This revision presents functions and properties of beneficial organisms and proposals are made for their use to benefit farmers and consumers, with the intention of contributing to the productive processes towards a sustainable agriculture.</p>

A country’s biodiversity is a key resource for the development of a sustainable bioeconomy. However, often the most biodiverse countries on the planet hardly profit from their biological diversity. On the contrary, occasionally components of that biodiversity become a threat to society and its food sustainability. That is the case of the sugarcane borer Diatraea saccharalis. Here, the analysis of the bacteria associated with the digestive tract of D. saccharalis reveals a rich and diverse microbiota. Two types of diets were analyzed under laboratory conditions. The metataxonomic analysis revealed a number of taxa common to most of the larval pools analyzed with relative abundances exceeding 5%, and five families of bacteria which have also been reported in the gut of another Lepidoptera. A large fraction of microorganisms detected by amplicon sequencing were considered to be rare and difficult to cultivate. However, among the cultivable microorganisms, 12 strains with relevant biotechnological features were identified. The strain that showed the highest cellulolytic activity (GCEP-101) was genome sequenced. The analysis of the GCEP-101 complete genome revealed that the values of 16S rRNA identity, the Average Nucleotide Identity, and the digital DNA–DNA hybridization place the strain as a candidate for a new species within the genus Pseudomonas. Moreover, the genome annotation of the putative new species evidenced the presence of genes associated with cellulose degradation, revealing the hidden potential of the pest as a reservoir of biotechnologically relevant microorganisms.
