“…Although the morphology of these animals has been characterised in some detail for taxonomic purposes and aspects of their courtship behaviour described, these chelicerates have only recently been studied in the context of EvoDevo research (Jędrzejowska et al 2013 ). Elucidating the genetic mechanism whereby chelate pedipalps are patterned in pseudoscorpions and scorpions may shed much needed light on how these groups are related ( Fig.…”

“…Such a situation has been elegantly demonstrated in spiders (Morishita et al, ). To the best of our knowledge, open stalks in the preovulatory phase have been reported only in the pseudoscorpions, but untimely ovulation is apparently blocked by the follicular cells persisting at the base of the oocyte (Jędrzejowska et al, ). In the katoikogenic scorpions studied here, the diverticulum is devoid of a lumen until late stages of oogenesis (Figures and ).…”

“…The authors have suggested that vesicles located in the apical cytoplasm of the stalk cells “may represent traffic of substances to be released and captured by the oocyte”. In the pseudoscorpion Chelifer cancroides , the stalk cells contribute to the synthesis of the chorion in the preovulatory phase, while after ovulation they produce components of nutritive fluid, which is a source of nutrients for developing embryos (Jędrzejowska et al, ). It has been previously reported that in Schizomida the funicle (stalk) cells facing the oocyte secrete the material that is spread into the space between the funicle and the oocyte (Alberti & Palacios‐Vargas, ).…”

“…As mentioned above, the stalk cells fulfill a mechanical role, joining the growing oocytes with the ovarian wall. However, they also produce secretory products (Alberti & Palacios‐Vargas, ; de Oliveira, Mathias, & Bechara, ; Jędrzejowska, Mazurkiewicz‐Kania, Garbiec, & Kubrakiewicz, ; Miyazaki & Bilinski, ), and participate in ovulation (Morishita et al, ).…”

The structure of diverticula of the female gonads was analyzed in two scorpions from the family Scorpionidae by means of standard microscopic techniques (light microscopy, histochemistry, transmission electron microscopy). In scorpions, the female gonad, termed the ovariuterus, participates in two consecutive processes: oogenesis and embryogenesis. In sexually reproducing scorpions, the ovariuterus is also involved in fertilization. Both scorpions under study reproduce sexually. They also represent the katoikogenic type of development, which means that oogenesis, fertilization, and embryogenesis take place in the diverticula, which are sac‐like outpocketings of the ovariuterine tubules. Formation of a lumen in the diverticulum is indispensable for sperm entry to enable fertilization and subsequent embryogenesis. The aim of the study was to test our hypothesis that the diverticulum lumen forms due to the engagement of the centrally located stalk cells. In this report, we show that in two species of katoikogenic scorpions, at the final stages of oogenesis, the cytoplasm of the stalk cells contains secretory organelles. In the stages preceding fertilization, secretory activity of the stalk cells and fragmentation of their apical parts lead to formation of the diverticulum lumen by a process similar to “cord hollowing” that commonly occurs for lumen formation in other morphogenesis model systems.

Chelifers (Pseudoscorpions) are generalist predators of small prey such as mites. Their occasional presence in honeybee hives suggests potential to exploit them as part of a management programme against Varroa mites (Varroa destructor), a significant pest of honeybees. Two species of native New Zealand chelifers Nesochernes gracilis and Heterochernes novaezealandiae, shown to consume Varroa mites, were collected from commercial nucleus hives or in litter surrounding the hives. Methods for mass‐rearing the chelifers were developed to provide specimens for research and introduction into beehives for biological control of Varroa. Cultures were fed aphids and fruit fly larvae in vented containers containing sand and bark. N. gracilis was maintained at 14°C, 18°C, and 22°C. At 18°C, 1423 nymphs were reared from 140 N. gracilis adults, with 84.8% of all nymphs produced at this temperature. H. novaezealandiae was maintained at 18°C and 22°C, with 5 nymphs raised from 12 adults at 18°C and none at the higher temperature.
