Abstract L-3,4-dihydroxyphenylalanine (L-DOPA), a naturally occurring tyrosine derivative, is prevalent in environments that include mosquito habitats, potentially serving as part of their diet. Given its role precursor for melanin synthesis we investigated the effect dietary L-DOPA on physiology and immunity to Plasmodium falciparum Cryptococcus neoformans infection. Dietary was incorporated into via non-canonical pathway had profound transcriptional effects were associated with enhanced immunity, increased pigmentation, reduced lifespan. Increased melanization resulted an capacity absorb electromagnetic radiation affected temperatures. Bacteria microbiome sources dopamine, which substrate melanization. Our results illustrate how environmentally abundant amino acid analogue can affect suggest potential usefulness friendly vector control agent reduce malaria transmission, warranting further research field studies.

Introduction Riptortus pedestris is a destructive pest that threatens multiple leguminous crops in China. The intestinal microbiota plays crucial role the growth and reproduction of host insects. However, composition function gut at different developmental stages remain unclear. Methods Here, metagenomic sequencing was performed to clarify microbial diversity 2nd-, 3rd-, 4th-, 5th- instar nymphs (2 N–5 N) female adults (FAs) R. effects vital bacteria on development detected. have stage specificity, indicating their . Results Enterococcus Caballerronia were predominant present during 2 N–FAs. In addition, abundances 3 N 4 guts significantly greater than those others guts. Furthermore, 5 harbored abundant Burkholderia - Paraburkholderia Caballeronia metabolic pathways enriched from FAs. Carbohydrate metabolism, including glycoside hydrolases (GHs) glycosyl transferases (GTs), occurs throughout entire stage. Many antibiotic resistance genes (ARGs) detected Pseudomonadota Bacillota presented broad spectrum resistance.

Microbial communities play a crucial role in the physiological characteristics, adaptability, and reproductive success of arthropods. However, patterns functions microbial variation across different life stages mites remain poorly understood. In this study, we used high throughput Illumina sequencing 16S rRNA gene to investigate composition functional potential bacterial five (larva, protonymph, deutonymph, tritonymph, adult) oribatid mite Eremobelba eharai . We found significant differences diversity community structure despite being fed same diet. The was highest at protonymph stage lowest tritonymph stage. Beta analysis indicated distinct compositions among stages. Bacteroidota, Proteobacteria, Firmicutes dominated throughout host's cycle. Key genera, such as Bacillus, Streptomyces, Achromobacter , Tsukamurella showed abundance Predicted profiles revealed substantial changes metabolic pathways, which may reflect nutritional needs E. during its developmental process. PICRUSt prediction results also that most KEGG larval adult consistently maintain similar relative abundances bacteria. Different deutonymph show consistent “biosynthesis other secondary metabolites” “glycan biosynthesis metabolism” pathways. This study provides new insights into dynamic within lays foundation for further research on interactions between microorganisms.

ABSTRACT The gut microbiota plays a vital role in nutrient and energy utilization, as well the host's ability to adapt its immune system environmental changes. As biological control agent for invasive Parthenium weed, beetle Zygogramma bicolorata ( Z. ) Pallister is often exposed fluctuating temperatures, which may induce stress natural habitat. This study utilized 16S amplicon sequencing explore impact of temperature on microbiome under cold (15°C), (27°C), hot (35°C) conditions. A total 11 bacterial phyla 149 genera were identified, with Firmicutes, Proteobacteria, Cyanobacteria being most abundant. Temperature treatments significantly influenced diversity microbiota, evidenced by alpha measures. Principal coordinate analysis further revealed substantial variations composition across different Additionally, PICRUSt2 suggested that linked metagenomic functions related amino acid carbohydrate transport, inorganic ion metabolism, cellular processes. Our findings suggest thermal alters beetles, offering new insights into how these beetles have ecologically adapted fluctuations, while also highlighting potential microbes maintaining health stress.
