The role of behavioral mechanisms in animal invasions is poorly understood. We show that asymmetric mating interactions between closely related but previously allopatric genetic groups the whitefly Bemisia tabaci, a haplodiploid species, have been driving force contributing to widespread invasion and displacement by alien populations. conducted long-term field surveys, caged population experiments, detailed observations Zhejiang, China, Queensland, Australia, investigate process its...

Polymer nanodots (PNDs) from a hybrid carbon source (glucose and glycine) which exhibit stronger fluorescence than the PNDs single or are obtained by one-pot hydrothermal treatment. It is attractive that can be used as an effective fluorescent probe for detection of iron ions with good selectivity sensitivity in aqueous solution.

Summary Intraspecific variation in dietary breadth can influence important ecological and evolutionary processes, yet the mechanisms generating this are usually unknown. Maternally transmitted bacterial symbionts frequently infect insect herbivores, many have been shown to mediate key interactions. For polyphagous infection with particular is often strongly correlated feeding on plant species, suggesting that facultative might directly determine herbivore food specificity. However, previous...

Abstract Endosymbionts are important components of arthropod biology. The whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is a cryptic species complex composed ≥ 28 putative species. In addition to the primary endosymbiont Portiera aleyrodidarum , six secondary endosymbionts (S‐endosymbionts), Hamiltonella Rickettsia Wolbachia Cardinium Arsenophonus and Fritschea have been identified in B. thus far. Here, we tested five S‐endosymbiont lineages (excluding ) from 340 whitely...

The solenopsis mealybug, Phenacoccus solenopsis, has been recently recognized as an aggressively invasive pest in China, and is now becoming a serious threat to the cotton industry country. Thus, it necessary investigate molecular mechanisms employed by for defending against P. before populations reach epidemic levels. Here, we examined effects of exogenous jasmonic acid (JA), salicylic (SA), herbivory treatments on feeding behavior development female solenopsis. Further, compared volatile...

Abstract The whitefly, Bemisia tabaci Gennadius (Homoptera: Aleyrodidae), harbors primary and secondary endosymbionts. Previous research showed that the invasive B biotype an indigenous non‐B (named ZHJ‐1 population) of B. from Zhejiang, China, harbored different To investigate function these endosymbionts in two biotypes , we fed adult whiteflies with three antibiotics, tetracycline, ampicillin trihydrate, rifampicin, evaluated fitness their offspring on cotton plants. These antibiotics did...

Abstract The whitefly Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae) is a species complex, and its systematic classification requires controlled crossing experiments among genetic groups. Accurate information on pre‐copulation intervals, copulation frequencies, initial frequency of egg fertilization newly emerged adults critical for designing procedures collecting the virgin necessary these experiments. In literature, considerable variation reported between B. populations, with respect...

Abstract The whitefly Bemisia tabaci has a global distribution and extensive genetic diversity. Recent phylogenetic analyses as well crossing experiments suggest that B. is complex composed of > 20 cryptic species, but more studies are required to examine the reproductive compatibility among putative species thus further clarify systematics this complex. We conducted behavioral observations investigate between Mediterranean, Asia II 3, 1 collected from Zhejiang, China. Female progeny were...

Three new Talaromyces species isolated from soil are reported here, namely T. dimorphus (ex-type strain AS3.15692 T), lentulus AS3.15689 T) and mae AS3.15690 T). is characterized by biverticillate monoverticillate penicilli, ampulliform phialides, slimy texture with sparse mycelial funicles absent conidiogenesis on MEA. featured vivid yellow mycelium Cz MEA, CYA, globose smooth-walled conidia. presents conidia CYA YES, funiculous floccose ovoid Both morphological molecular characters show...

Abstract A deep understanding of the molecular interactions carbon nanodots with biomacromolecules is essential for wider applications both in vitro and vivo. Herein, nitrogen sulfur co‐doped dots (N,S‐CDs) a quantum yield 16% were synthesized by 1‐step hydrothermal method. The N,S‐CDs exhibited good dispersion, graphite‐like structure, along fluorescence lifetime approximately 7.50 ns. Findings showed that was effectively quenched bovine hemoglobin as result static quenching. mentioned...

Abstract Begomoviruses are exclusively transmitted by whitefly (Bemisia tabaci) in a circulative, non-propagative manner. The influences of begomoviruses on vector complex with both direct and indirect effects. However, the molecular mechanisms underlying these effects poorly understood transcriptional profiles healthy virus-infected plants have not yet been studied. Using suppression subtractive hybridization, we investigated differentially expressed genes Middle East – Asia Minor 1 feeding...

A novel sensor was developed based on the electrostatic layer-by-layer (LBL) self-assembly technique a glassy carbon electrode (GCE) modified with nitrogen-doped graphene (NG) and polyethylenimine (PEI). Electrochemical studies exhibit that assembled NG multilayer films have favorable electron transfer ability electrocatalytic property, which could enhance response signal towards dopamine (DA) in presence of ascorbic acid (AA). In addition, possess an excellent sensing performance for...

A simple and straightforward synthetic approach for carbon nanodots (C-dots) is proposed. The strategy based on a one-step hydrothermal chemical reduction with thiourea urea, leading to high quantum yield C-dots. obtained C-dots are well-dispersed uniform size graphite-like structure. synergistic mechanism was investigated using Fourier transform infrared spectroscopy X-ray photoelectron spectroscopy. findings show that both urea during the one-pot synthesis enhances luminescence of...

Background Talaromyces species play an important role in the nutrient cycle natural ecosystems, degradation of vegetal biomass industries and implications medicine. However, diversity this genus is still far from fully understood. Methods The polyphasic taxonomic approach integrating morphological comparisons molecular phylogenetic analyses based on BenA , CaM Rpb2 ITS sequences was used to propose three new species.
