Traps made by rectangular pieces of 3 mm thick corrugated cardboard of four different sizes, 200 by 140 (A), 140 by 100 (B), 100 by 70 (C), and 200 by 40 mm (D), were evaluated as a sampling device for the chicken mite, Dermanyssus gallinae (De Geer). Mites were trapped during 2, 4, 6, 8, and 10 d, respectively, in a poultry house heavily infested with the parasite. Significantly greater number...

BACKGROUND: Chemical control of spider mites and thrips in everbearer strawberry is difficult as few efficient chemicals are available and residues represent a risk. In the north the success of biocontrol of mites and thrips in open fields compared with tunnels needs to be evaluated. OBJECTIVES: To investigate the need for control of spider mites and thrips and evaluate the effectiveness of bio...

The present-day distribution of velvet worms corresponds neatly to the ancient supercontinent Gondwana - except for a puzzling outpost in southeast Asia. Jaw-dropping new fossil material now establishes when and how peripatid onychophorans reached this isolated spot.

The subclass Acari (mites and ticks) comprises two super-orders: Acariformes and Parasitiformes. Most species of the Parasitiformes known retained the ancestral pattern of mitochondrial (mt) gene arrangement of arthropods, and their mt tRNAs have the typical cloverleaf structure. All of the species of the Acariformes known, however, have rearranged mt genomes and truncated mt tRNAs. We sequence...

INTRODUCTION The infestation by mites of stored products is of great economic importance and public health, with consequences to human health. OBJECTIVES To describe the mite species associated to food and stored products that cause implications to human health as well as to analyze the loss of quality and nutritional composition of infested food. METHOD Literature review in LILACS-BIREME, ...

Water mites of Unionicola spp. are common parasites of freshwater mussels as adults, living on the gills, or mantle and foot of their hosts and using these tissues as sites of oviposition. The present study addresses specialization among North American Unionicola mussel-mites using 2 measures of host specificity: (1) the number of host species used by a species of mite; and (2) a measure that c...

Abamectin has been widely used as an insecticide/acaricide for more than 30 years because of its superior bioactivity. Recently, an interesting phenomenon was identified in the carmine spider mite, Tetranychus cinnabarinus, an important pest in agriculture. The gamma aminobutyric acid (GABA) contents in a laboratory abamectin resistant strain of T. cinnabarinus (AbR) were significantly increase...

Miniature inverted-repeat transposable elements (MITEs) are prevalent in eukaryotic species including plants. MITE families vary dramatically and usually cannot be identified based on homology. In this study, we de novo identified MITEs from 41 plant species, using computer programs MITE Digger, MITE-Hunter and/or Repetitive Sequence with Precise Boundaries (RSPB). MITEs were found in all, but ...

The velvet family proteins have been shown to play critical roles in fungal secondary metabolism and development. However, variations of the roles have been observed in different fungi. We report here the observation on the role of three velvet complex components VeA, VelB, and LaeA in Pestalotiopsis microspora, a formerly reported taxol-producing fungus. Deletion of individual members led to t...

A patient showing antibody-mediated rejection (AMR) with severe vasculitis, and massive proteinuria after kidney transplantation was treated with deoxyspergualine (DSG, Spanidin((R)), Nippon Kayaku). DSG showed marked efficacy for this patient's symptoms. We report on a patient for whom DSG was effective against AMR after renal transplantation.
