Tick pheromones that regulate assembly, attraction/aggregation/attachment, and mating behavior have been described. Most of the compounds regulating these behaviors are purines, substituted phenols, or cholesteryl esters. Other pheromonal compounds include organic acids, hematin, or ecdysteroids. Novel devices have been developed that combine the specific compounds comprising these pheromones w...

Tick infestations and tick-borne diseases continue to be the leading causes of loss in livestock revenue, particularly developing countries, despite prevalent use synthetic acaricides. Research on plants as alternative sources anti-arthropod agents has received attention from many researchers recent past. This interest is mainly motivated by compelling need move away over-reliance chemicals, wh...

BACKGROUND As obligate blood-feeding arthropods, ticks transmit pathogens to humans and domestic animals more often than other arthropod vectors. Livestock farming plays a vital role in the rural economy of Pakistan, and tick infestation causes serious problems with it. However, research on tick species diversity and tick-borne pathogens has rarely been conducted in Pakistan. In this study, a s...

Small rodents serve as reservoir hosts for tick-borne pathogens, such as the spirochetes causing Lyme disease. Whether natural coinfections with other macroparasites alter the success of tick feeding, antitick immunity, and the host's reservoir competence for tick-borne pathogens remains to be determined. In a parasitological survey of wild mice in Berlin, Germany, approximately 40% of Ixodes r...

Ticks had to adapt to an existing and complex vertebrate hemostatic system from being free-living scavengers. A large array of anti-hemostatic mechanisms evolved during this process and includes blood coagulation as well as platelet aggregation inhibitors. Several questions regarding tick evolution exist. What was the nature of the ancestral tick? When did ticks evolve blood-feeding capabilitie...

proteases play a key role in protein digestion in ticks and other haematophagous insects. our understanding of blood meal digestion in digestive system of ticks can be very useful for better understanding of basic rules for control of ticks. cells of the midgut endocytose blood components. blood proteins uptake by midgut cells, suggesting the presence of proteases in the midgut cells. in this s...

b a ckground: diagnostic study of vector ticks for different pathogens transmitted specifically have been done by iranian old scientists working on the basis of biological transmission of pathogens. in this study we decided to con- firm natural infection of different collected ticks from three different provinces of iran. m e t hods: ticks were collected from livestock (sheep, goats and cattle)...

INTRODUCTION Tick-borne diseases such as Lyme disease, Rocky Mountain spotted fever, and ehrlichiosis are a significant concern for many thousands of workers who have frequent and unavoidable exposure to tick-infested habitats. Many North Carolina state employees with outdoor occupations report multiple tick bites each year, indicating that existing tick preventive strategies may be underutiliz...

Ticks are capable of transmitting viruses, bacteria, protozoa, and rickettsiae to man. Several of these tick-borne pathogens can lead to pulmonary disease. Characteristic clinical features, such as erythema migrans in Lyme disease, or spotted rash in a spotted fever group disease, may serve as important diagnostic clues. Successful management of tick-borne diseases depends on a high index of su...
