In this study, the post-larval (female) stage of Abrolophus bochkovi Hakimitabar, Saboori & Fadaei, 2020, previously known only from the larval stage, is described for the first time through experimental laboratory rearing. Larval specimens from Türkiye and Iran were compared to confirm the species identification. In addition, detailed drawings, photographs, and morphometric data are provided for the female of this species. With this contribution, the number of Abrolophus species described from both larval and post-larval stages increases to four. The present study was conducted at Erzincan Binali Yıldırım University between 2023 and 2025.

In this survey, soil samples obtained from Erzincan and Bayburt provinces (Türkiye) between 2013 and 2022 were evaluated. Eleven species of the superfamily Erythraeoidea Robineau-Desvoidy, 1828 are reported for the first time for the Turkish mite fauna. While 9 of the detected species [Abrolophus artemisiae (Schrank, 1803); Abrolophus miniatus (Hermann, 1804); Abrolophus quisquiliarus (Hermann, 1804); Abrolophus rhopalicus (Koch, 1837); Abrolophus strojnyi Gabryś, 1992; Balaustium murorum (Hermann, 1804); Moldoustium haitlingeri Noei, Saboori & Šundić, 2013; Erythraeus (Erythraeus) cinereus (Dugès, 1834) and Erythraeus (Zaracarus ) rupestris (L., 1758)] belong to the family Erythraeidae Robineau-Desvoidy, 1828, and two species [Fessonia papillosa (Hermann, 1804) and Smaris squamata (Hermann, 1804)] belong to the family Smarididae Vitzthum, 1929. In addition, the diagnosis of the genus Moldoustium Haitlinger, 2008 is re-presented. Also, erythraeoid mites recorded from Türkiye so far are listed.

The study was conducted to determine the insecticidal and behavioral effect of essential oils (EOs) extracted from three lavender cultivars, Hemus, Raya and Yubileina, against adult stage of Sitophilus granarius (L., 1758) (Coleoptera: Curculionidae) under laboratory conditions. The contact, fumigant and repellent effects of plant EOs were investigated and possible germination inhibitory effects of the EOs on wheat germination were evaluated. EOs were extracted from the plant samples using a Neo-Clevenger type apparatus where the plant material is subjected to hydro distillation. The chemical constituents of EOs were detected by gas chromatography-mass spectrometry. The experiments were conducted under laboratory conditions in 2019 and 2020. As a result of the study, it was determined that the fumigant activity changed according to the cultivars. While the LC90 value in the fumigant activity of the EOs of the Hemus was determined as 0.157 µl/ml air, this value was recorded as 0.139 µl/ml air and 0.118 µl/ml air in Raya and Yubileina, respectively. Six h after treatment, the highest repellent activity was 86% at 0.05 µl/cm2 with Yubileina. Main EOs components of each cultivar were: Yubileina, linalool (36.0%), linalyl acetate (24.2%) and lavandulyl acetate (5.86%); Hemus, linalool (28.5%), linalyl acetate (23.1%) and lavandulyl acetate (6.59%); and Raya, linalool (42.5%), linalyl acetate (30.0%) and -terpineol (5.45%). There was no negative effect on the germination of wheat with any of essential oils. These results show that lavender EOs could be useful for the control of S. granarius.

In this study, it was investigated some oribatid mites living in Uzunoluk forest (Erzurum-Turkey) and the species of fungi isolated from the mites. From the field chosen as research area, thirteen oribatid mite species were identified. From these species, Hermannia (Hermannia) gibba, Carabodes (Flexa) intermedius, Poroliodes farinosus, Gymnodamaeus bicostatus, Suctobelbella (Suctobelbella) subtrigona, Oribatula (Oribatula) interrupta, Rhinoppia hygrophila and Liebstadia (Liebstadia) humerata are new for the Turkish Fauna. In addition, Liacarus (Liacarus) coracinus, Scheloribates (Scheloribates) pallidulus, Eupelops torulosus, Oribatula (Zygoribatula) exilis and Tectocepheus velatus were reported in this field for the first time. Electron microscope photographs of the identified mites were taken. In the study, their distinguishing properties were presented and their distribution all over the world was given. Fungi were isolated from both inner and outer surfaces of mites. After the collected fungi were located to agar medium, investigating colonial properties and cellular structures of those completing their development, were taken. The fungi that were isolated were determined to be Beauveria bassiana, Chrysosporium sp., Clonostachys rosea (Gliocladium roseum), Fusarium sp., Paecilomyces farinosus, Penicillium expansum and Penicillium steckii and finally the relationship between these fungi and mites were discussed.

Phoretic mites (Acarina: Mesostigmata: Uropodidae) were identified on the red palm weevil (RPW), [(Rhynchophorus ferrugineus (Oliver, 1790) (Coleoptera: Curculionidae)] collected from the aggregation pheromone traps and the dead Canary Island date palms, Phoenix canariensis Hort. in Adana province, Turkey in 2008. Two phoretic uropodid species, Uropoda orbicularis (Muller, 1776) and Uroobovella marginata (Koch, 1839) (Acarina: Uropodidae) were recorded for the first time on the RPW in Turkey. The uropodid mites were found mainly beneath the first wings of the adult weevils. They were also observed on dead larval and pupa stages of the RPW. The majority of the adult weevils, collected from the traps in the period may-june and date palm trees in february, carried the high numbers of uropodid mites. Mean total numbers of the total mites on the pheromone traps for the period of may-june were 213.02 (max. 698) on per adult female and 188.85 (max. 653) per adult male. Mean total numbers of mites in the date palm trees in february were 346.70 (max. 668) per adult female and 283.10 (max. 644) per adult male in date palms. RPW, found inside the cocoons in the date palms, were infested with the great numbers (400-600) of the mites. Total numbers of the total uropodid mites on the larval and pupal stage of RPW varied from 0 to 50. Densities of the phoretic mites attached to the adult females and males collected from the trap and palm tree samplings were usually similar throughout the sampling periods. The uropodids exhibited typically phoretic behavior on the RPW individuals. They may have hampered partly the flight behaviors of the weevils, particularly in the spring in Adana province.

Adana ilinden 2008 yılında, feromon tuzaklarıyla ve yalancı hurma (Phoneix canariensis Hort.) ağaçları üzerinden toplanan Kırmızı palmiyeböceği (KPB), Rhynchophorus ferrugineus (Oliver, 1790) (Coleoptera: Curculionidae) foretik akar türleri bakımından incelenmiştir Bu çalışmayla Türkiye’de ilk kez KPB üzerinde foretik akar türleri, Uropoda orbicularis (Müller 1776) ve Uroobovella marginata (Koch 1839) (Acarina: Uropodidae) saptanmıştır. Uropodidae türleri esas olarak ergin böceklerin elytrasının altında bulunmuştur. Bu akar türleri KPB’nin ölmüş olan son dönem larvaları ve pupalarında da kaydedilmiştir. Mayıs-haziran döneminde tuzaklarda ve şubat ayında KPB zararı nedeniyle kesilen yalancı hurma ağaçlarında ergin böceklerin çoğunun yüksek sayılarda uropodid akarlarla ile bulaşık oldukları saptanmıştır. Mayıs-haziran döneminde tuzaklardaki dişilerde ortalama uropodid akar sayısı 213.02 (maksimum 698); erkeklerde ise 188.85 (maksimum 653) olmuştur. Şubat ayında kesilen ağaçlardaki ergin dişilerde ortalama akar sayısı 346.70 (maksimum 668) olurken, ergin erkeklerde 283.10 (maksimum 644) olarak kaydedilmiştir. Kokon içerisindeki ergin dişi ve erkek böceklerin çoğunluğunun yüksek yoğunluklarda (400-500 adet) uropodid akar ile bulaşık olduğu bulunmuştur. KPB’nin larva ve pupalarında uropodid akar sayısı çoğunlukla 0-50 adet akar arasında değişmiştir. Ergin erkek ve dişi böcekler örnekleme dönemi boyunca genelde benzer yoğunluklarda akar taşımışlardır. Bu çalışmada saptanan akarların tipik foretik davranış göstermelerine karşın, bunların özellikle bahar aylarında KPB erginlerinin uçuş aktivitelerini kısmen de olsa olumsuz yönde etkileyebilecekleri kanaatine varılmıştır.
