In order to study fauna of Cryptinae, Pimplinae and Tryphoninae (Hymenoptera: Ichneumonidae), three Natural Protection Areas (Halep Çamlığı, Kengerlidüz, and Habib-i Neccar) were chosen sampled by various techniques from East Mediterranean Region of Turkey between 2007-2008. The same localities were again sampled between 2014-2015 and added. A total of 112 samples were collected and 38 species determined. Eleven species are new records for Turkey. Centers of diversity are given for each species.

The organization of ant communities can be affected by vegetation characteristics and by interspecific interactions. We evaluated the roles of vegetation complexity/heterogeneity and interspecific interactions on the organization of ant communities in two contrasting habitats. A total of 25 species of ants were collected in pitfall traps in the Cerrado (13 species) and in the Atlantic forest (22 species). Beta diversity (Dβ) was higher among Atlantic forest trees and the plant height positively affected the richness of ants. Greater Dβ in the Atlantic forest environment could be explained by the greater complexity of the vegetation in this environment. Co-occurrence analyses have shown that interspecific interactions are more important in shaping ant community organization in the Cerrado than in the Atlantic Forest. Low availability of resources can generate interspecific competition and competitive exclusion. Thus, the variation in resource availability could explain the results of the co-occurrence analyses. Finally, the importance of resource availability for the conservation of ant diversity is discussed.

Aphid species, their parasitoids and predators on Curled dock (Rumex crispus L.) naturally grown in Erzincan and Erzurum provinces, Turkey were determined. Surveys were conducted at two week intervals from the seedling period until the end of the harvest period in 2017 and 2018. In the surveys, 30-40 plants were randomly selected and all parts of these plants were investigated with a magnifier. Four aphid species, thirteen predator and two parasitoid species were found. Rumex crispus was recorded for the first time as a host of Acyrthosiphon rubi Narzikulov (Hemiptera: Aphididae). In addition, parasitism rates of aphids were also established. The mean parasitism rate changed between 23.2% in 2017 and 23% in 2018. The relationship between total aphid number, total parasitized (mummified) aphid number and parasitism rate was measured. There was a high positive correlation (r = 0.838-0.861) between total aphid number and total parasitized aphid number, and a weak or intermediate correlation (r = 0.180-0.412) between total aphid number and parasitism rate during both growing seasons.

A laboratory experiment was conducted on two potential reproductive host plant species of the whitefly Bemisia tabaci (Gennadius). The two plant species, Brassica carinata A. Braun (carinata or Ethiopian mustard) and Myrica cerifera L. (southern wax myrtle), were considered for study as potential overwintering host species for B. tabaci because of their presence with green foliage in the southeastern United States agricultural community from the fall through spring season. The Middle-East-Asia Minor 1 of the cryptic whitefly species group of B. tabaci survives the mild winters in the southeastern United States. In this study, B. carinata was demonstrated to be a favorable host plant for B. tabaci. Based on a no-choice experiment, oviposition, egg hatch, and survival to the adult stage were similar for whiteflies on B. carinata as compared with collard (B. oleracea var. acephala de Condolle), a known favorable host for B. tabaci. However, results from a dual choice experiment indicated that the whiteflies preferred B. carinata to B. oleracea for feeding and oviposition. Conversely, although southern wax myrtle served as an ovipositional host, the ovipositional performance of B. tabaci in a no-choice assay was over eight-fold less than on B. carinata, and nymphal survival was not successful beyond the second instar on southern wax myrtle in a laboratory experiment. However, a few nymphs survived to the fourth instar on intact plants of southern wax myrtle in the landscape. The results of this study have implications on whitefly population dynamics. Winter populations of B. tabaci are suppressed in the field, but plant species, such as carinata or collard, that are present during the mild winter may help support a buildup of whiteflies during the spring.

The long green planthopper Saccharosydne procerus is one of the serious pests of water-oat Zizania latifolia. Characterization of its antennal sensilla is vital for developing practical monitoring and management strategies of this pest. In the present study, the antennae of S. procerus (with particular focus on the sensilla) are illustrated using scanning electron microscopy. The results show that the antennae of both sexes are similar. The flagellum consists of an apical segmented arista and a basal bulb. Four types of sensilla were identified: campaniform sensilla, trichoid sensilla, chaetic sensilla and plaque organs. The campaniform sensilla are found on the distal rim of the scape. The trichoid sensilla I are sparsely distributed on the scape, and the trichoid sensilla II are densely distributed on the 3/4 distal area of the pedicel. The chaetic sensilla are sparsely distributed on the outer margin of the scape and pedicel. Abundant plaque organs are exclusively distributed at the distal area of the pedicel. The morphology and distribution of sensilla are compared and their possible functions are discussed.

Hesperocorixa scabricula (Walley) and the eastern Nearctic species Sigara compressoidea (Hungerford) and Sigara knighti Hungerford are reported from Alberta, Canada for the first time. We also update the current checklist of Canadian Hemiptera with Alberta records of Arctocorisa planifrons (Kirby), Glaenocorisa cavifrons (Thomson), Sigara lineata (Forster), and Sigara mullettensis (Hungerford) and provide a complete checklist of Alberta Corixidae.

The holotype of Delphacodes guianensis Muir, a delphacid planthopper (Hemiptera: Fulgoroidea: Delphacidae) currently nominally in the polyphyletic genus Delphacodes Fieber, was examined and found to bear lateral teeth on the hind basitarsus, a synapomorphy of the genus Nilaparvata Distant. We determined that Delphacodes guianensis is a senior synonym of Nilaparvata serrata Caldwell. Here we move this species into Nilaparvata to provide the new combination Nilaparvata guianensis (Muir) and give Nilaparvata serrata as a new junior synonym.

The giant willow aphid (GWA), Tuberolachnus salignus (Gmelin) was reported for the first time from the cold arid region of Ladakh, India. The identification of GWA was done based on morphological and molecular characterization. The important morphological characters of GWA are grayish-golden color, covered with numerous fine hairs with a large dark brown tubercle in the center of the back. GWA is a serious pest of willow and poplar trees. There is a need to study the biology and host selection behavior of this pest to develop effective management strategies.

Thecodiplosis japonensis Uchida & Inouye, one of the most destructive pests of pine forests in Korea, has colonized and has caused serious damage in some areas in China. Effective monitoring techniques and integrated control methods based on biological control need to be further researched and developed.

A new species, Zodarion gaziantepense sp. n. is described from the southeastern region of Turkey. Z. gaziantepense sp. n. can be easily distinguished from all other Turkish and European representatives of the genus by the structure of a triangular-shaped median apophysis.

We studied the pollination biology of a native orchid Spiranthes australis in Kobe, Hyogo, Japan, and observed that S. australis flowers are frequently visited by the managed honeybee A. mellifera. Since the honeybees extracted pollinaria from the anthers and deposited pollinia on the stigmas of many flowers, the behavior resulted in the successful pollination of multiple flowers even in a single visitation. Given that (i) the honeybee was the most frequent and intensive pollinator during our observation period and (ii) the fruit set in the investigated population was significantly higher than the fruit set of a previously investigated S. australis population, despite lack of ability for autonomous self-pollination, A. mellifera may promote a high reproductive success in S. australis. Our observation provides some insight into the diversity of orchid-pollinator interactions, drawing attention to the potential importance of non-native bees as pollinators.
