Caliscelidae records from Turkey are summarized. The tribe Adenissini Dlabola is recorded for the first time from the country after Perissana bispinata (Dlabola, 1980) collected in Mardin Province. New records for Ommatidiotus iranicus Horváth, 1905 and Bruchoscelis peculiaris (Horváth, 1904) are given.

The genus Kovalius is recorded as new for the Turkish harvestman fauna by the collection of Kovalius logunovi Tchemeris, 2023 from Kürtün district of Gümüşhane province, Turkey. Brief morphological descriptions are provided for the newly record species. Also, the genital morphology of the female was described and photographed for the first time.

Cigarette beetles Lasioderma serricorne (Fabricius, 1792) and saw-toothed grain beetles Oryzaephilus surinamensis (Linnaeus, 1758) are considered serious stored grain pests. Developing silica nanoparticles (SNs) coated with the most effective and persistent photosensitizer is a viable alternative to current synthetic chemical pesticides. Chemical characterization confirmed the conjugation process between SNs and rose bengal (RB) and formation of SNs photosensitizer rose bengal (SNP-RB). Additionally, bioassays were performed to determine the impact of the median-lethal concentration (LC₅₀) of the three substances against pests. The corresponding LC₅₀ values against L. serricorne and O. surinamensis were 5.14, 20.32, 50.60 and 9.79, 28.93, 106.29 for SNP-RB, SNs and RB respectively. Therefore, the toxicity of these tested compounds after three hours of sun light exposure could be descendingly arranged in order as follows: SNP-RB, SNs and RB.

The relative percentages of mineral contents were detected in the whole body tissue of L. serricorne and revealed the existence of nine elements in untreated adults, 11 elements in adults treated with RB as well as nine elements in adults treated with SNP-RB. Silicon was the least abundant element in both controls as well as adults treated with SNP-RB, Sulphur was the least abundant element in adults treated with RB and carbon was detected as the most abundant element in all treatments. Considering O. surinamesis, ten elements existed in untreated adults, 11 elements in adults treated with RB, whereas ten elements were found in adults treated with SNP-RB. Carbon was the most abundant element in all treatments, whereas calcium appeared as the least abundant element in SNP-RB.

The phoretic interaction between Americhernes oblongus (Say) (Chernetidae) and Mallodon chevrolatti (Thomson) (Cerambycidae) is documented for the first time. Furthermore, with this record, the distribution of A. oblongus to western Panama is expanded. This study contributes to our knowledge of the pseudoscorpion fauna in the central part of America, particularly shedding light on phoretic interactions. Americhernes oblongus is now documented for the first time in West Panama, expanding the known distribution within the country. The discovery includes a female specimen found attached to a male Mallodon chevrolatii. This finding not only marks the initial occurrence of A. oblongus on the western side of the isthmus but also represents the first report of a phoretic interaction between these organisms. This study contributes to our knowledge of the pseudoscorpion fauna in the central part of America, particularly shedding light on phoretic interactions.

The main objective of the present laboratory investigation was designed to evaluate the integrated impact of commercial formulation Xentari 54% WP (Bacillus thuringiensis aizawai) and gamma radiation against 4^th instar larvae of Agrotis ipsilon. Full grown male pupae were irradiated with the sub-sterilizing dose 100Gy. The resulting 4^th instar larvae of first generation (F1) were exposed to four different concentrations (3x10⁴, 6x10⁴, 9x10⁴ and 12x10⁴ D.U./100ml). Also, the mortality percentage was recorded daily in unirradiated fourth instar larvae treated with the same Bt. concentrations. The accumulative daily mortality revealed that when concentrations and time increased, the mortality percentage increased as well. The LC₅₀ and LC₉₀ levels of irradiated and unirradiated A. ipsilun F1 4^th larval instars treated after 24 hours of feeding on leaves treated with various concentrations of Bt. (Xentari 54% WP) revealed that irradiated parents of A. ipsilon F1 4^th larval instar were more vulnerable to Bt. than unirradiated ones. Also, histological study was carried out to describe the histological changes of the midgut tissues F1 larvae due to influence of gamma radiation either alone or in combination with LC₅₀ of Bt. Results obtained revealed that large number of epithelial cells became vacuolated. The histopathological symptoms were severe which was clearly obvious by cells lysis and unclear of the epithelium nuclei. The combination of Bt. and gamma radiation may offer an acceptable integrated pest management program against A. ipsilon.
