Potentially, pathogenic bacteria are one of the main infective agents against which a battery of chemical and physical barriers has evolved in animals. Among these are the secretions by the exocrine uropygial gland in birds. The antimicrobial properties of uropygial secretions may prevent colonization and growth of microorganisms on feathers, skin and eggshells. However, uropygial gland secreti...

Miniature inverted-repeat transposable elements (MITEs) are short, nonautonomous DNA elements that are widespread and abundant in plant genomes. Most of the hundreds of thousands of MITEs identified to date have been divided into two major groups on the basis of shared structural and sequence characteristics: Tourist-like and Stowaway-like. Since MITEs have no coding capacity, they must rely on...

Miniature inverted-repeat transposable elements (MITEs) are dispersed in large numbers within the genomes of eukaryotes although almost all are thought to be inactive. Plants have two major groups of such MITEs: Tourist and Stowaway. Mobile MITEs have been reported previously in rice but no active MITEs have been found in dicotyledons. Here, we provide evidence that Stowaway MITEs can be mobili...

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...

Miniature inverted-repeat transposable elements (MITEs) are a particular type of defective class II elements present in genomes as high-copy-number populations of small and highly homogeneous elements. While virtually all class II transposon families contain non-autonomous defective transposon copies, only a subset of them have a related MITE family. At present it is not known in which circumst...

The utility of USDA-developed Russian and varroa sensitive hygiene (VSH) honey bees, Apis mellifera L. (Hymenoptera: Apidae), was compared with that of locally produced, commercial Italian bees during 2004-2006 in beekeeping operations in Alabama, USA. Infestations of varroa mites, Varroa destructor Anderson & Truman (Acari: Varroidae), were measured twice each year, and colonies that reached e...

Two new genera Makarovaia and Hispiniphis are described from adults and immatures of newly described species associated with hispine beetles of the genera Chelobasis and Cephaloleia, respectively, occupying unfurled leaves of Heliconia in lowland rainforest of Costa Rica. The new genera share a suite of unique morphological attributes, but are tentatively assigned to the family Melicharidae. Wh...

Summary House dust mites and storage have a high allergenic potential lead to sensitization through the formation of specific IgE antibodies. Due their preferred residence in houses, they belong group house mites, which are referred as “domestic mites” English. Their anatomy biology account for amazing adaptability changing environmental situations (including temperature, humidity, food) make i...

A preliminary study related to mites associated in the insects is given in this article. Ten species of mites under nine families collected from six orders of insects from South Bengal are reported here giving collection data and biological information.
