  • 20 April 2004
Most female ixodid ticks, once mated, feed to repletion within 6-10 days. Previous studies indicate that an engorgement factor (EF), passed to the female during copulation, may be the stimulus for… Expand

Adaptations of arboviruses to ticks.
Arboviruses differ from other viruses in their need to replicate in both vertebrate and invertebrate hosts. The invertebrate is a blood-sucking arthropod that is competent to transmit the virus… Expand

Gluttony and sex in female ixodid ticks: How do they compare to other blood-sucking arthropods?
Abstract The central issue dealt with here is the role of copulation in the control of feeding behaviour in ticks and some haematophagous insects. Female ticks of the family Ixodidae normally engorge… Expand

Cypermethrin inhibits egg development in the ixodid tick, Amblyomma hebraeum
The pyrethroid insecticide, cypermethrin (CyM), stimulates vitellogenesis in Ornithodoros moubata (an argasid tick) by stimulating the release of the normal vitellogenesis-inducing factor (a… Expand

Modification of the skin feeding site by tick saliva mediates virus transmission
A tick vector of Thogoto (THO) virus was shown to secrete a factor in saliva which potentiates the transmission of THO virus to uninfected ticks feeding on an apparently non-viraemic host. The effect… Expand
