Geographic variation and core microbiota composition of (Diptera: Tephritidae) infesting a single host across latitudinal and altitudinal gradients.

is a pestiferous tephritid fly species exhibiting extreme polyphagy. It develops optimally in hosts rich in sugar but low nitrogen content. We studied the geographical influence on the composition of 's larval and newly emerged adult gut microbiota in altitudinal (0-2,000 masl) and latitudinal (ca.

Expansion to new habitats and a new commercial host (Malus domestica) by Anastrepha ludens (Tephritidae) likely influenced by global warming.

Anastrepha ludens (Mexican fruit-fly) is a highly polyphagous fruit fly species (Tephritidae) attacking wild and commercial fruit from Mexico to Panama. Here we report on a recent habitat and host range expansion as A. ludens lately started to attack apples (Malus domestica) in Mexico, a phenomenon likely influenced by global warming.

Insights into the differences related to the resistance mechanisms to the highly toxic fruit (Malpighiales: Euphorbiaceae) between the larvae of the sister species and (Diptera: Tephritidae) through comparative transcriptomics.

The Manchineel, ("Death Apple Tree") is one of the most toxic fruits worldwide and nevertheless is the host plant of the monophagous fruit fly species (Diptera: Tephritidae). Here we aimed at elucidating the detoxification mechanisms in larvae of reared on a diet enriched with the toxic fruit (6% lyophilizate) through comparative transcriptomics. We compared the performance of larvae with that of the sister a highly polyphagous pest species that is unable to infest in nature.

Larval Rearing and Nutrition of the Polyphagous Tephritid Pest on Artificial Diets with Calcium Alginate, Agar, or Carrageenan as Gelling Agents at Various Concentrations and across Extreme Larval Density Conditions.

Research on larval rearing and nutrition of tephritid flies on artificial diets is key for the sterile insect technique. Here, we examined the effects of the type of gel (calcium alginate, agar, or carrageenan), at varying percentages in artificial diets for the polyphagous pest , on the physicochemical and nutritional traits of the diets, and the effects of the type of gel, the gel content and the larval density (larvae/g of diet) used in production, quality parameters for mass-reared tephritids, diet removal (an indirect estimation of diet consumption), and nutritional traits of flies. Regardless of the gel content, calcium alginate diets were firmer and more resistant to penetration than the agar and carrageenan diets.

Complete mitochondrial DNA profile in stroke: A geographical matched case-control study in Spanish population.

Introduction: Stroke, the second leading cause of death worldwide, is a complex disease influenced by many risk factors among which we can find reactive oxygen species (ROS). Since mitochondria are the main producers of cellular ROS, nowadays studies are trying to elucidate the role of these organelles and its DNA (mtDNA) variation in stroke risk. The aim of the present study was to perform a comprehensive evaluation of the association between mtDNA mutations and mtDNA content and stroke risk.
