Field surveys were carried out to determine the thrips fauna in cereal production areas of the Lakes Region in Turkey in 2016 and 2017. Thysanoptera specimens were collected with destructive and strike methods in two periods (before and after spike) from each production field during the production season. Thrips specimens were identified based on morphological taxonomic characters. Species distribution maps, species richness, abundance, as well as Shannon–Wiener (H') index, species seasonal dynamic and species sex ratio were calculated to indicate the diversity of Thysanoptera species in the Lakes Region. We also calculated Pearson correlation coefficient to evaluate correlation between Thysanoptera species richness and host plant richness. Species Distribution Modelling, namely MaxEnt algorithm, was used in order to establish the current and future distributional patterns of Thysanoptera species collected in our research area. During the two years of the study, 27,603 specimens of Thysanoptera were collected in production fields of wheat, oat and barley. There were 51 different species from four families. Haplothrips tritici was the most abundant species with 15,284 specimens or 55.371% of all collected. The highest relative abundance within family Thripidae was recorded for Collembolothrips mediterraneus, Chirothrips manicatus, Thrips angusticeps, Thrips herricki and Limothrips cerealium. Considering the altitudinal gradient of the study area, the highest species richness and abundance were found between 950 and 1,050 m.a.s.l. with 40 species and 7,622 specimens recorded. Potential species richness of Thysanoptera revealed an increase in areas that predominantly encompass eastern parts of Burdur province, as well as central north parts of Isparta.

The purpose of this study was to evaluate how irradiated hosts affected the mass rearing of the ectoparasitoid Bracon brevicornis Wesmael. To investigate the development of B. brevicornis stages on three hosts; full-grown larvae of Pectinophora gossypiella, Galleria mellonella, and Spodoptera litoralis were irradiated with 100, 200, and 300 Gy. The use of 100Gy in irradiating P. gossypiella and G. mellonella produced utilization in promoting parasitism and adult emergence of B. brevicornis, with parasitism percentages of 77.00% and 80.00% for P. gossypiella and G. mellonella, respectively, when compared to control larvae or other irradiated doses. The results of the biochemical experiments showed that G. mellonella > P. gossypiella > S. littoralis was the order of the insects in terms of total protein, lipids, and glucose. It could be concluded that using 100Gy irradiated P. gossypiella and G. mellonella larvae would aid in improving B. brevicornis mass production and the effectiveness of B. brevicornis.

Radiation technique proved its excellence as a clean pest control tool. Therefore, the present study was directed to explore the biochemical variation in Spilostethus pandurus (Scop.) (1^st and 5^th nymph instar and 2-day-old male adults) irradiated with different gamma radiation doses (50, 100, 150 and 200 Gy). The testis lactate dehydrogenase and acid phosphatase activities were also estimated in the adult males. The results exhibited a significant decrease in the metabolic products (protein, lipids, and carbohydrates), and the antioxidants response (glutathione–S-Transferase and glutathione reduced) when compared to control. Contrarily, lipid peroxidation content was significantly elevated when compared to the control. Furthermore, the arrangement of the studied ages according to the content of the tested parameters was 2-day-old male adults > 5^th nymph instar > 1^th nymph instar. The testis lactate dehydrogenase and acid phosphatase activities showed a significant increase in the irradiated males. In conclusion, it was observed that gamma radiation generated damaging effects in the physiological system of the different stages of S. pandurus, so it could be used for S. pandurus control.

New state records of species of the flat-backed millipede family Paradoxosomatidae (Diplopoda: Polydesmida) are made for Mexico: Akamptogonus novarae (Humbert and Saussure, 1869) is recorded for the state of Nuevo Leon; Asiomorpha coarctata (Saussure, 1860) is recorded for the states of Estado de Mexico, Nuevo Leon, Tamaulipas and Oaxaca; Chondromorpha xanthotricha (Attems, 1898) is recorded for the states of Chiapas, Hidalgo, Nuevo Leon, Tamaulipas and Yucatan; and Oxidus gracilis (C.L. Koch, 1847) is recorded for the states of Coahuila and Tamaulipas. We also present two new cases of predation on Oxidus gracilis from a railroad worm (Coleoptera: Phengodidae) larva and a vinegaroon (Thelyphonida: Thelyphonidae).

The female of Rafalskia azizsancari Kurt, Yağmur & Tezcan, 2019, previously known only from the male in Turkey, is now described based on new material from Ödemiş District, İzmir Province, Turkey. Detailed morphological descriptions, photographs and illustration of the female ovipositor are provided.

Here we report a new case of gynandromorph moth in the fall armyworm (FAW), Spodoptera frugiperda. According to the morphology, the gynandromorph moth belongs to bilateral-gynandromorph due to exhibited morphs of female and male on both sides. In addition, the moth has deformed genitalia in both the female and male.

Two young nests of Dolichovespula arenaria were each found to have been invaded by a Vespula squamosa queen. The first nest was successfully usurped, while the usurpation process was ongoing in the second nest. This latter observation confirms that V. squamosa queens will invade well-established nests. Factors involved in the selection of D. arenaria as a new intergeneric host are briefly discussed.

A phoresy of the pseudoscorpion Haplochelifer philipi (Chamberlin, 1923) in a phoretic association with Acrocinus longimanus was observed in Bocas del Toro Province, Panama. A phoretic female found under the elytra of the beetle. This is the first time that H. philipi has been reported in Panama.
