Larval Feeding Habits of Five Firefly Species Across Aquatic, Semi-Aquatic, and Terrestrial Lineages.

While adult fireflies are terrestrial, their larvae inhabit various habitat types, and a lack of comprehensive research on the feeding habits of these larvae across different habitats has greatly impeded the development of artificial diets. Here, we tested 14 types of foods, primarily covering gastropods, vertebrates, and fruit, to survey feed for aquatic ( and ), semi-aquatic ( and sp.), and terrestrial () fireflies.

Mitochondrial phylogeography of grassland caterpillars (Lepidoptera: Lymantriinae: ) endemic to the Qinghai-Tibetan plateau.

Grassland caterpillars (Lepidoptera: Lymantriinae: ) are the most damaging pests to alpine meadows in the Qinghai-Tibetan Plateau (QTP). Here, we conducted extensive sampling from 39 geographic populations covering almost the entire distribution of the eight QTP (Hübner) species to investigate phylogeographic patterns and speciation based on two mitochondrial genes ( and ). A total of 40 haplotypes were detected in the 39 populations, with >70% of all haplotypes not shared between populations.

Electrostatic-Field-Induced Collapse of Nanobubbles in Nanochannels.

The adsorbed nanobubbles inside the nanochannels can cause fluid transport blockages, which will obviously degrade the nanodevice performance and reduce the lifetime. However, due to small-scale effects, the removal of nanobubbles is a huge challenge at the nanoscale. Herein, molecular dynamics simulations are carried out to study the effect of the electrostatic field on underwater nitrogen nanobubbles confined in nanochannels.

Ultrahigh-Flux Water Nanopumps Generated by Asymmetric Terahertz Absorption.

Controlling active transport of water through membrane channels is essential for advanced nanofluidic devices.

Copper/Cu has posed the most serious threats to amphioxus, an ancient and model benthic cephalochordate. Herein, a dynamic change in the physiological parameters (GR, SOD, ATP, and MDA) was detected with ROS accumulation in Branchiostoma belcheri exposed to 0.

Genomic and characteristics of a novel strain AACE3 isolated from fermented blueberry.

Numerous different species of LAB are used in different fields due to their unique characteristics. However, , a newly established species in 2018, has limited microorganism resources, and lacks comprehensive evaluations of its properties.

A novel bacteriocin against multiple foodborne pathogens from isolated from juice ferments: ATF perfusion-based preparation of viable cells, characterization, antibacterial and antibiofilm activity.

Foodborne pathogens and their biofilms pose a risk to human health through food chain. However, the bacteriocin resources combating this threat are still limited. Here, one of the most used probiotics in food industry, was prepared on a large scale using alternating tangential flow (ATF) perfusion-based technology.

Assessment of the safety and probiotic characteristics of CGMCC20700 based on whole-genome sequencing and phenotypic analysis.

Lactic acid bacteria are generally regarded as alternatives to antibiotics in livestock and poultry farming, especially strains, which are safe and have probiotic potential. Although has long been proposed to be a probiotic, the understanding of the roles of this species is still in its infancy.

Subcellular-Level Mitochondrial Energy Metabolism Response in the Fat Body of the German Cockroach Fed Abamectin.

Mitochondria are the leading organelle for energy metabolism. The toxic effects of environmental toxicants on mitochondrial morphology, energy metabolism, and their determination of cell fate have already been broadly studied. However, minimal research exists on effects of environmental toxicants such as pesticides on mitochondrial energy metabolism at in vitro subcellular level, particularly from an omics perspectives (e.

Transcriptomic data recover a new superfamily-level phylogeny of Cucujiformia (Coleoptera, Polyphaga).

Cucujiformia, the largest taxon in the order Coleoptera, exhibits extraordinary morphological, ecological, and behavioral diversity. This infraorder is currently divided into seven superfamilies, but considerably incongruent relationships among superfamilies have been reported by recent phylogenomic studies.

A method for isolating highly purified and active mitochondria from insects.

So far, methods that yield the high purity and activity of the isolated mitochondria from insects have not been reported and determined. Here, we develop methods that combine differential centrifugation and discontinuous Nycodenz density gradient centrifugation to isolate highly purified mitochondria from the thorax muscle of insects, and the methods were widely validated across three orders (Coleoptera, Hymenoptera, and Blattaria) covering four insect species using Western blot and transmission electron microscopy (TEM) analysis. The results showed the removal of the residual contamination with nonmitochondrial components such as nucleus, sarcolemma, cytosol, and endoplasmic reticulum.
