  author={Alicja Buczek and Katarzyna Bartosik and Alicja Buczek and Weronika A Buczek and Dorota Kulina},
The increasing application of toxic plant substances to deter and fight ticks proves the need for investigations focused on the elucidation of their impact on the developmental stages and populations of these arthropods. We examined the course of embryogenesis and egg hatch in Hyalomma marginatum ticks under the effect of cytotoxic plant substances. The investigations demonstrated that the length of embryonic development of egg batches treated with 20 μL of a 0.1875% colchicine solution did not… Expand
Teratological anomalies of an adult Asiatic blue tick, Rhipicephalus microplus (Acari: Ixodidae)
Teratological anomalies occur at low frequencies in ticks. However, this phenomenon has been reported for several species of the genera Argas, Ornithodoros, Amblyomma, Dermacentor, Ixodes,Expand
Morphological abnormalities in ticks (Acari: Ixodidae) collected from domestic animal species in Sudan
This study presents the first report of local anomalies in ticks belonging to three genera in Sudan and highlights the need to investigate the association between such morphological abnormalities and tick biology. Expand
Hyalomma anatolicum resistance against ivermectin and fipronil is associated with indiscriminate use of acaricides in southwestern Balochistan, Pakistan
This study highlights the urgency to implement a country-wide awareness about resistance monitoring and effective tick control and suggests the development of acaricide resistance against fipronil and ivermectin against H. anatolicum. Expand
A case of morphological anomalies in Amblyomma americanum (Acari: Ixodidae) collected from nature
A case of morphological anomalies in Amblyomma americanum, a medically important species associated with several human diseases and medical conditions, is described, believed to be the first report of the presence of several spontaneous anomalies in one Am. Expand
Morphological anomalies in Rhipicephalus sanguineus s.s. (Acari: Ixodidae) collected from dogs in steppe and high plateaus regions, Algeria.
The present report describes morphological anomalies in Rhipicephalus sanguineus s.s. collected from dogs between February 2017 and May 2019 in the steppic region of Djelfa and high plateau area ofExpand
A teratologic spider with duplicated reproductive organs
Abstract. In general, malformations in spiders involve chelicerae, pedipalps, walking legs, and eyes, but those affecting female reproductive structures are not so frequent. A teratological case of aExpand
Teratological changes in postembryos of Eratigena atrica obtained by the application of alternating temperatures on spider embryos
By exposing spider embryos to the temperatures of 14 °C and 32 °C, changed every 12 hours for the first 10 days of their development, 74 postembryos of Eratigena atrica with body deformities were obtained and it was concluded that there was no relationship between the fusion of legs and the structure of the central nervous system.

Investigations showed that during the formation of the blastoderm, theformation of the germ band and its metamerization the embryos have the largest susceptibility of being affected by high humidity. Expand
Sensitivity to permethrin in a Dermacentor reticulatus population from eastern Poland in laboratory study
Permethrin can be recommended for D. reticulatus control, particularly in the case of tick resistance to other chemical substances, but only at the doses applied permethrin decreased the reproductive rate of females, which may result in a decrease in tick abundance already in the first generation. Expand
Anomalies in Hyalomma marginatum larvae (Acari: Ixodidae) in relation to taxonomic studies
The investigations have shown low variability of the morphometric traits of tarsi I and III as well as coxae I, II, and III in the H. marginatum larvae from the Syrian population, which can be used in the diagnostics of this species. Expand
Evaluation of the effect of various concentrations of selected pyrethroids on the development of Dermacentor reticulatus eggs and larvae.
Investigations showed that the pyrethroids tested prolonged the egg maturation period, reduced the number and weight of eggs, and caused disturbances in embryogenesis in D. reticulatus. Expand
Morphological abnormalities in ticks (Acari: Ixodidae) feeding on humans in Central Black Sea region, Turkey
In the present study, morphological abnormalities in ticks collected on humans were investigated in detail for the first time and many forms of Morphological abnormalities were reported for Turkey. Expand
The effect of sublethal concentrations of deltamethrin and alphacypermethrin on the fecundity and development of Ixodes ricinus (Acari: Ixodidae) eggs and larvae
This study investigates the effect of sublethal concentrations of D and AC applied to engorged females on the fecundity, development of eggs and larvae, and the number of offspring in the Ixodes ricinus (L.) tick, which is the most important vector of tick-borne diseases of humans in Europe. Expand
The life cycle of the tick Hyalomma marginatum rufipes Koch (Acarina: Ixodidae) under laboratory conditions.
The life cycle of Hyalomma marginatum rufipes Koch was studied under laboratory conditions and the premolting period of nymphs to adults of both sexes was similar. Expand
Study of the non-parasitic stage in Ixodes ricinus after co-feeding with Dermacentor reticulatus in three infestations.
The results indicate that co-feeding with other tick species may partially reduce the influence of host resistance in subsequent infestation. Expand
