Both the geographical range and local densities of\n D. reticulatus<\/jats:italic>\n are steadily increasing in many regions of Europe. In the present study, we tested the hypothesis that\n D. reticulatus<\/jats:italic>\n possesses an efficient breeding strategy that allows for a rapid increase in tick numbers and densities through the formation of mixed-sex clusters\/aggregations while questing in the environment.\n <\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n An observational study was carried out in the spring of 2023, at three sites in two regions in Central and North-Eastern Poland, both characterised by high tick densities. At each site, a 400-m-long transect was inspected for questing ticks. All noted ticks were collected, and tick numbers and sexes per stem were recorded. Differences in tick distribution by site and sex were analysed statistically.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n A total of 371\n D. reticulatus<\/jats:italic>\n (219 females, 152 males) ticks were collected from 270 grass stems over a combined 1200\u00a0m of transect. The majority of grass stems (74.4%) were occupied by just a single individual, with two-tick clusters the second most common category. The maximum number of\n D. reticulatus<\/jats:italic>\n individuals observed on a single grass stem was six.\n <\/jats:p>\n Mixed-sex clusters were significantly more common than single-sex clusters at all three sites. With study sites combined, mixed-sex clusters accounted for 17.4% (95% confidence limit [95% CL]\u200913.9\u201321.6%) of observations, while for multiple males and multiple females, the values were 2.6% (95% CL: 1.4\u20134.7%) and 5.6% (95% CL: 3.7\u20138.3%), respectively.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n \n Mixed-sex clusters of\n D. reticulatus<\/jats:italic>\n ticks were significantly more common than single-sex clusters, which we hypothesise reflects an efficient, likely pheromone-mediated breeding strategy of this expansive tick species.\n <\/jats:p>\n <\/jats:sec>\n \n Graphical Abstract<\/jats:title>\n <\/jats:sec>","DOI":"10.1186\/s13071-024-06129-4","type":"journal-article","created":{"date-parts":[[2024,2,9]],"date-time":"2024-02-09T06:02:20Z","timestamp":1707458540000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Mixed-sex clusters on grass blades: breeding strategy of the ornate dog tick, Dermacentor reticulatus"],"prefix":"10.1186","volume":"17","author":[{"given":"Dagmara","family":"W\u0119\u017cyk","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wiktoria","family":"Romanek","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wiktoria","family":"Ma\u0142aszewicz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jerzy M.","family":"Behnke","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Bajer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2024,2,9]]},"reference":[{"key":"6129_CR1","doi-asserted-by":"crossref","unstructured":"Oliver JH.
