Based on winter flagging experiments on Long Island, NY, adult Ixodes scapularis Say have an apparent threshold of questing activity at 4 degrees C. This threshold should be incorporated into public education efforts because the public may be at risk of contracting Lyme disease any time during the winter when temperatures exceed 4 degrees C.

Female engorgement weight, oviposition, and molting times of larvae and nymphs of Amblyomma maculatum Koch (Acari: Ixodidae) were studied at various photoperiods under constant humidity and temperature in the laboratory. Ticks were held at photoperiods of 0:24, 10:14, 12:12, or 14:10 (L:D) h from egg through unfed nymphal stage and then at either the same or a different regime from fed nymphs t...

Despite its importance, our knowledge of pathogen transmission by ticks is incomplete. Detailed studies on the transmission, maintenance, infectivity, virulence, and pathogenicity of tick-borne microparasites all require the use of large numbers of live ticks raised under controlled conditions and difficulties in rearing ticks in the laboratory could partly explain the current lack of data. The...

Canine hepatozoonosis is a tick-borne protozoan disease spread by hard ticks of the Ixodidae family. Although this illness has been seen in numerous locations Türkiye, its existence Batman and Van provinces yet to be confirmed. The purpose research was look into canine stray dogs from two distinct areas Türkiye using conventional polymerase chain reaction (PCR). Between 2019 2021, blood samples...

Hard ticks (Acari: Ixodidae) and tick-borne diseases are considered as a threat in several parts of Europe. In Finland, both Ixodes ricinus persulcatus have shifted northwards recent decades, they become more abundant at the same time. This is thought to be due global climate change its effect directly on or indirectly their host animals. review focuses factors that affect tick activity surviva...

The author analyzed the first 5 days of embryonic development of Ixodes ricinus. The cleavage takes 4 days, being terminated on the 5th day of embryogenesis, when the cells start to invaginate and differentiate. The karyomeres play a role in the initial mitotic divisions. Cellularization occurs on the 2nd and 3rd day of embryogenesis. The blastoderm cells maintain their potential for division, ...

a survey was carried out to investigate the frequency of hard tick species (acari: ixodidae) on sheep in khorasan razvi province. a total of 812 ticks were collected from the sheep of different areas of khorsan razavi province five species were identified as follow: rhipicephalus turanicus (59.23%), hyalomma.marginatum turanicum (25.73%), hyalomma excavatum (14.8%), hyalomma anatolicum (8.3...

Ixodes (Afrixodes) matopi n. sp. is described from females and males collected off twigs bearing deposits of intraspecific communication marks secreted by the pre-orbital glands of the klipspringer Oreotragus oreotragus and from laboratory-reared immature specimens. One female was also found on a goat. The 4 collections were all from Zimbabwe, 3 of them from Matabeleland South Province and the ...

The two internal transcribed spacers (ITS1 and ITS2) of rDNA of three members of the Ixodes ricinus "complex" (Acari: Ixodidae) were sequenced. Sequence variation was assessed for the North American species I. scapularis, I. dammini, and I. pacificus at three levels: within individual/population, between individuals of different geographic origin within a species, and between species. Both spac...

Oviposition and eclosion periods for Ixodes didelphidis were observed under two temperatures (25 degrees C and 27 degrees C) and 90-95% humidity. Although there was a significant increase in the eclosion period (p<0.05) and a tendency to increase the oviposition period at 25 degrees C, there was neither significant differences in the interval (days), until maximum peak of eclosion nor in the nu...
