| long-term ecological study of host-seeking adults of hyalomma lusitanicum (acari: ixodidae) in a meso-mediterranean climate. | from january 2007 to december 2014, three representative meso-mediterranean bioclimatic environment types were sampled monthly using blanket-dragging techniques to determine the tick abundance rate. hyalomma lusitanicum koch, 1844 was the most prevalent species (96.58%) followed by dermacentor marginatus sulzer, 1776; rhipicephalus pusillus gil collado, 1936; and rhipicephalus bursa canestrini and fanzago, 1878. h. lusitanicum adults begin questing activity around march, numbers rising quickly r ... | 2016 | 26477051 |
| seasonal dynamics of ixodid ticks on wild rabbits oryctolagus cuniculus (leporidae) from central spain. | rabbit hemorrhagic disease and myxomatosis caused a decline in the rabbit population in the second half of the last century. despite some recovery, the risk of vector-borne disease is present and thus the importance of controlling vector populations. in the current study, we describe the ixodid tick fauna in wild rabbit in a natural reserve in ciudad real (central spain) during the course of two 3-year periods (2007-2009 and 2012-2014). of all the ticks collected on average 72.5 % were larvae, 2 ... | 2016 | 27411939 |
| long term study of ixodid ticks feeding on red deer (cervus elaphus) in a meso-mediterranean climate. | red deer (cervus elaphus l.) are very valuable in trophy-hunting but also contribute to the preservation of natural areas. they are affected by many parasites and pathogens, including hard ticks that are not only important parasites themselves but can also act as vectors and/or reservoirs of pathogens. tick phenology is complex insofar as population dynamics depend on environmental conditions, vegetation, host availability and their own intrinsic characteristic. ticks were collected monthly from ... | 2016 | 26715543 |
| insect antifeedant and ixodicidal compounds from senecio adenotrichius. | nine eremophilane sesquiterpenes 1 - 9, two flavonoids 11 and 12, and two known pirrolizidine alkaloids 13 and 14, were isolated from senecio adenotrichius dc. their structures were elucidated on the basis of spectroscopic data and by comparison with previously reported spectroscopic data of similar compounds. compounds 5, 7, and 9 have not been previously reported as natural products. the antifeedant activity of these compounds was tested against spodoptera litoralis and myzus persicae. eremoph ... | 2017 | 27546067 |
| control of tick infestations in oryctolagus cuniculus (lagomorpha: leporidae) with spinosad under laboratory and field conditions. | because of great economic loss in the world's livestock industry, and the serious risks to human health, the control of ticks and tick-borne diseases is one of the most important health management issues today. current methodology involves integrated tick control for preventing the development of resistance. rabbits are hosts for immature stages of the three-host tick hyalomma lusitanicum koch; so, we focus on this host as a strategy to interrupt the tick life cycle. spinosad is an insecticide-a ... | 2015 | 26336305 |
| [scanning electron microscopy study for an analytical key to the hyalomminae (ixodidae) species to be found in italy]. | identification of ticks of hyalomminae subfamily is easy for the species of subgenus hyalommasta schulze (coxa l with two equal, stump and short, well separated spurs) and for those of the subgenera hyalommina schulze and delpyella santos dias (basis capituli with lateral margins anteriorly divergent). all the species of subgenus hyalomma koch have the coxa i deeply divided in adjacent narrow external spur and wider internal spur, and the basis capituli rectangular, with parallel or subparallel ... | 1996 | 9333752 |
