Biscutulumnemus neotropicus gen. nov., sp. nov. (Tarsonemidae: Tarsoneminae: Tarsonemini) is described from adult female and male mites, collected on Croton floribundus Spreng., from São José do Rio Preto, State of São Paulo, Brazil. This new genus resembles members of Dendroptus and Tarsonemus, but male mites have two triangular shields anterolaterally to the prodorsal shield and the sejugal a...

This study was conceived to detect skin mites in social mammals through real-time qPCR, and to estimate taxonomic Demodex and further Prostigmata mite relationships in different host species by comparing sequences from two genes: mitochondrial 16S rRNA and nuclear 18S rRNA. We determined the mite prevalence in the hair follicles of marmots (13%) and bats (17%). The high prevalence found in marm...

Three levels (high, low and control) of northern fowl mite, Ornithonyssus sylviarum (Canestrini and Fanzago), were maintained on White Leghorn hens for 24 weeks. The hens were then treated with carbaryl to eradicate the mites, were induced to molt, and were reinfested with mites 9 weeks later. Subsequent levels of mites on the three groups showed that the degree of acquired immunity was related...

Transposable elements (TEs) have played important roles in the evolution of genes and genomes of higher eukaryotes. Among the TEs in the rice genome, miniature inverted-repeat transposable elements (MITEs) exist at the highest copy number. Some of MITEs in the rice genome contain poly(A) signals and putative cis-acting regulatory domains. Insertion events of such MITEs may have caused many stru...

background: blood sucking mites are important avian ectoparasites which being found on bird species worldwide. their presence are problematic for the producers either through potential direct effects on weight gain, egg produc­tion, sperm production in roosters or as nuisance pests on worker handle hens and eggs. the aim of this study was pointing out of the status of haematophagus mites. metho...

OBJECTIVES Sensitisation of asthmatic patients to mites in sub-Saharan Africa has been less described. The aim of this study was to assess the prevalence and determinants of sensitisation to mites in asthmatic adolescents and adults in Yaounde, Cameroon. DESIGN This was a cross-sectional study. Logistic regression models were employed to investigate the determinants of sensitisation to mites....

The article conducted research on the main species of spiders (Tetranychidae) in seed orchards and monitored their occurrence rates. According to him, a total 6 mites are recorded from belonging family Tetranychidae class mites. As result analysis natural cousins ​​of mites, 9 types ​​were recorded. most common these phytoseyulus, Mobius, Prius, stertorous beetle, metaseyulus, entomophagous. Ba...

Demodex mites may induce inflammatory cutaneous reactions such as papulopustular rosacea and demodex folliculitis; both may lead to post inflammatory pigmentation. A 59-year-old man presented with an asymptomatic, hyperpigmented plaque on his face. Histological and clinical findings displayed Riehl-like facial pigmentation. Multiple demodex mites at the follicular infundibulum in the biopsy mat...

Why is there so much variation within species in the extent to which males contribute to offspring care? Answers to this question commonly focus on intraspecific sources of variation in the relative costs and benefits of supplying paternal investment. With experiments in the laboratory on the burying beetle, Nicrophorus vespilloides, and its phoretic mite Poecilochirus carabi, we investigated w...
