Three aquatic species of true bugs (Heteroptera), the waterboatman Hesperocorixa atopodonta (Hungerford, 1927) (Corixidae) and the backswimmers Buenoa confusa Truxal, 1953 and Notonecta insulata Kirby, 1837 (both Notonectidae), are reported for the first time from Illinois based on specimens recently caught during a biological inventory of aquatic macroinvertebrates conducted in Pine Dunes County Forest Preserve. Additionally, a record corroborating the presence of Gerris buenoi Kirkaldy, 1911 (Gerridae) in the state is presented. Supplementing these notes are dichotomous keys to the species of Hesperocorixa Kirkaldy, 1908 and Notonectidae of Illinois.

Two Anopheles triannulatus genetic lineages were previously detected, differentially distributed at northwest (NW lineage) and southeast (SE lineage) Colombia. These lineages could differ in their biology and ability to transmit malaria. Although the lineages were molecularly defined using the 3' Cytochrome c oxidase subunit 1 (cox1 or COI) and the internal transcribed spacer 2-ITS2 sequences, a different cox1 region, the 5′ end, has been widely used for species identification in dipterans and may be used in differentiating these lineages. This study compared the variation between two cox1 gene regions, the 3' (Lunt) and 5' (Folmer) ends, in An. triannulatus from Colombia in order to evaluate their accuracy for identification at the lineage level. Results showed that the cox1 Folmer fragment would not facilitate detection of lineages in An. triannulatus, while cox1 Lunt allowed separation of specimens into the two perilously detected lineages, NW and SE.

Indian meal moth, Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae), is one of the most important insect pests of storage products. Considering the adverse effects of chemical pesticides, it is necessory to find substitute agents for managing insect pests, including P. interpuntella. Plant-derived essential oils have been introduced as suitable candidates to replace detrimental synthetic chemicals. Therefore, along with the toxicities of the essential oils of pistachio peel and basil leaves, their effects on the α-amylase enzymes and protein contents of 5^th instar larvae of P. interpuntella larvae were evaluated in the current study. Concentrations of the pistachio and basil essential oils were regarded to be 50-150 and 60-400 µl.l within 24 and 48 h exposure times, respectively. The results showed that the considered times and concentrations had significant effects on P. interpuntella larvae (P<0.01). The mortality rates increased by enhancing their concentrations. LC50 were 178.14 and 89.34 µl.l and 49.79 and 31.28 µl.l after 24 and 48 h, respectively. The essential oils demonstrating 30.8 and 37.8% of inhibitions for the relative α-amylase enzyme activities in the treated 5^th instar larvae were significantly different from those of the control group. The essential oils of pistachio peel and basil displayed promising potentials for the management of P interpunctella with especial fumigant toxicities capable of disrupting the protein content and α-amylase inhibitory activity.

Macromotettixoides angustivertex Zha & Peng sp. nov. and M. hainanensis (Liang) (= Hyboella hainanensis Liang), collected from Hainan Island, PR China, are described, photographed and compared with their allies. Based on the morphological characters of the two species, generic characteristics of the genus Macromotettixoides are updated. Pseudomacromotettix taiwanensis Zheng, Li & Lin, syn. nov. is synonymized with M. taiwanensis (Liang) (= Hyboella taiwanensis Liang), and the monotypic Pseudomacromotettix Zheng, Li & Lin, syn. gen. is synonymized with Macromotettixoides Zheng, Wei & Jiang. We also give ecological information for the two described species.

The natural enemies of the avocado stem weevil, (Copturus aguacatae Kissinger) (Coleoptera: Curculionidae), in the state of Nayarit, Mexico, were identified. Branch samples were taken biweekly during Feb–Dec 2015 in avocado orchards located in Tepic and Xalisco. The branches with C. aguacatae larvae were placed in cages and checked weekly until parasitoids or adult borers emerged. Eleven species of parasitic Hymenoptera were found; particularly abundant was Heterospilus bruchi (Viereck) (Braconidae). In addition, three species of entomopathogenic fungi (Metarhizium pingshaense, Metarhizium anisopliae and Beauveria bassiana) were identified associated with avocado stem weevil in Nayarit.

Aphrophora geruzei sp. n. is described from samples collected from Sinop and Kastamonu, in the Western Black Sea region of Turkey. This species has been found to have genital structure features different from the other species of Aphrophora. Morphological and genital structure characteristics of male and female materials of the species collected by the authors following the field studies conducted between May and October in 2017 are presented.

The present study aimed to investigate the impact of gamma radiation on isoenzymes (peroxidase and polyphenyl oxidase) and DNA damage in Trogoderma granarium. The newly emerged male adults were irradiated with substerilizing and sterilizing doses of gamma radiation for the experiments (100 and 200Gy). The results showed that there was no difference in the distribution of peroxidase and polyphenyl oxidase isoenzymes, and the intensity of peroxidase isoenzymes was the same between the tested samples when compared to the control population and each other. There was a variation in the intensity of the detected polyphenyl oxidase isoenzyme. The DNA electrophoresis showed fragmentation in the gamma irradiated adults as compared to the control. Therefore, it could be concluded that these parameters could be used as a biomarker for identification of gamma irradiated T. granarium males.

The black bug species Corimelaena harti (Hemiptera: Heteroptera: Thyreocoridae) was described over 100 years ago, yet practically no ecological information is known about the species. We newly report Galium concinnum (shining bedstraw) as a confirmed host plant and “mountain mint” as a second possible host plant. Further, we report this black bug species as a new state record for Ohio.

In this paper, two species are newly recognized from Turkey. One is new to science, described as Ozyptila kahramanmarasensis sp. n. on the basis of a male specimen from Kahramanmaraş Province. The other, Oxyptila patellibidens Levy, 1999 is found for the first time in Şanlıurfa Province.

We report 12 new observations of parasitically-founded Vespula flavopilosa colonies. Of these, 4 nests were identified directly by having been found in the pre-emergence stage, whereby only the resident queen was seen foraging before the presence of the first workers. Seven nests were found in the early phases of worker production, wherein the queen and first workers were foraging simultaneously, or nests were observed containing workers of both the host V. maculifrons and parasite V. flavopilosa freely foraging together. A twelfth nest, collected later in the season, appeared to have been the result of a usurpation of a V. germanica nest, based on gray paper found in the central cores of the first three combs of the nest. This represents the first report of V. flavopilosa utilizing the introduced V. germanica as a host species. These observations cover a wide part of the species' range, and imply that V. flavopilosa is a frequent temporary social parasite. Furthermore, this behavior appears to be obligatory since an incipient nest founded unequivocally by a V. flavopilosa queen has not been recorded.

Mintho compressa (Fabricius, 1787) (Diptera: Tachinidae) is recorded for the first time from Turkey. Taxonomically important morphological characters were photographed and an identification key for the Turkish Mintho species is presented.

This study was carried out in 2017 to detect populations of the xyllophagous fig pest Xylopertha reflexicauda (Lesne 1937) (Coleoptera: Bostichidae) in Diyarbakır Province of Turkey. This species has been determined to be a pest after culturing dead fig trees. This is the first report of its spread in Turkey, and the first reported damage to fig in Turkey. Features of the exit hole of the species and some feeding characteristics of the species are provided. This is an important addition to the fauna in Diyarbakır Province.
