Over the last decade, remote sensing technologies and geographical information systems have moved from the research arena into the hands of vector control specialists. This review explains remote sensing approaches and spatial information technologies used for investigations of arthropod pests and vectors of diseases affecting humans and livestock. Relevant applications are summarized with exam...

J. Med. Entomol. 25(1): 32-38 (1988) ABSTRACT Seasonal abundance of ectoparasites was estimated from monthly collections of Eastern (Sturnella magna (L.)) and Western (Sturnella neglecta Audubon) meadowlarks in Starr County, Tex. Ecological relationships of ticks, Amblyomma maculatum Koch, Amblyomma inornatum (Banks), and Haemaphysalis leporispalustris (Packard) (Acari: Ixodidae); lice, Menacan...

ticks are considered to be the main vectors for transmission of various diseases to animals and human. the present faunistic study aimed to determine species belonging to Ixodidae ticks, infesting cattle of Khoozestan province, south-west of Iran. Totally 1000 ticks were collected randomly from cattle from 9 locations in five geographical regions between January to September 2011, and were iden...

Ticks (Ixodidae and Argasidae) are important arthropod vectors of various pathogens that cause human animal infectious diseases. Many previously published studies on tick-borne focused those transmitted by ixodid ticks. Although there increasing reports viral associated with argasid ticks, information bacterial they transmit is scarce. The aim this molecular study was to detect characterize Ric...

The pathogenicity of four native strains of Bacillus thuringiensis against Rhipicephalus (Boophilus) microplus (Canestrine) (Acari: Ixodidae) was evaluated. A R. microplus strain that is resistant to organophosphates, pyrethroids, and amidines, was used in this study. Adult R. microplus females were bioassayed using the immersion test of Drummond against 60 B. thuringiensis strains. Four strain...

An oval-shaped mass with a smooth surface was found in the ear canal of a 22-month-old male infant. Although the mass appeared to be almost entirely blocking the ear canal, it was successfully removed under a surgical microscope without general anesthesia at the outpatient department. Under an optical microscope with hematoxylin and eosin staining, the specimen was observed to have a cuticle wi...

1. Pleomorphic, bacterium-like, Gram-negative, intracellular microorganisms, which stained much less intensely with ordinary dyes than most bacteria were found in sixteen species of ticks comprising examples of the Argasidae and the Ixodidae. 2. In six of these species studied intensively slight differences in the microorganisms were detected, sufficient to permit identification of the vectors ...

We report on the structure of the small-subunit ribosomal RNA (18S rRNA) sequence from Hyptiotes gertschi (Araneae, Uloboridae), which is the largest 18S gene sequenced in any arachnid to date. We compare this remarkable sequence to those from a range of other spiders and arachnids, and develop base-pairing models of its insert regions to determine its overall secondary structure. The H. gertsc...

Field surveys of ectoparasites on rodents and scandents were conducted in four localities of wildlife reserves in Peninsular Malaysia from October 2008 to November 2009. A total of 16 animals comprising 5 species of hosts were caught and examined for ectoparasites. The hosts examined were Maxomys rajah, Maxomys whiteheadi, Leopoldamys sabanus, Lariscus insignis and Tupaia glis. Of these hosts, ...
