The genus Telomerina Roháček 1983 from China is recorded to include five species: Four new species, Telomerina curvibasata sp. nov., T. laterispinata sp. nov., T. levicana sp. nov. and T. tuberculata sp. nov. One new record for Continental China, T. flavipes (Meigen). All new species are described and illustrated. A key to these species is presented.

Western cherry fruit fly, Rhagoletis indifferens Curran 1932 (Diptera: Tephritidae), was reared from naturally-infested Chinese crabapple, Malus spectabilis (Aiton) Borkhausen (Rosaceae), in Washington State, U.S.A. Pupae from Chinese crabapple were smaller than those from sweet cherry, Prunus avium (Linnaeus) Linnaeus (Rosaceae), but fecundity and longevity of flies from the two hosts did not differ. Laboratory experiments were conducted to compare larval development in crabapples and cherries. ‘Snowdrift’ crabapples (Malus × ‘Snowdrift’) did not produce pupae. Percentages of ‘Indian Magic’(Malus ‘Indian Magic’) ‘Radiant’ crabapple (Malus ‘Radiant’) vs. sweet cherry replicates that produced pupae did not differ in two no-choice experiments (36.7 vs. 41.7% and 13.3 vs. 33.5%, respectively). In a choice experiment, the percentage of crabapple replicates that produced pupae (6.7%) was lower than that of cherry replicates (42.2%). Egg to pupal development times in crabapples (18.0–21.2 d) were longer than in cherries (15.4–16.7 d) and pupae from the crabapples were smaller. Results suggest crabapples are not optimal developmental hosts for R. indifferens but that Chinese and ‘Indian Magic’ ‘Radiant’ crabapples can occasionally allow late-season flies to bridge the gap between one generation and the next when no cherries are available.

Xyleborinus artestriatus (Eichhoff 1878), an ambrosia beetle native to Asia, is reported for the first time in North America based on specimens from Georgia and Texas. This is the twenty-fourth species of exotic Xyleborini documented in North America. North American distributional records, key identification characteristics, morphological variability, and a brief history of the systematics are presented.

Two new species, Tautoneura hamula and T. trimaculata spp. n. from China, are added into the genus Tautoneura Anufriev 1969.

Using recently collected material from Taiwanese localities where Sauter collected in the early 20th century, the present study redescribes 2 species and renames “O. sauteri” of Zhang and Yang (2006) as Ochthera mudigerensis (Zhang & Yang 2006).

Accurately stating the nature of plant-insect interactions is essential for our understanding of the insect, its role in the ecosystem, and the evolution of the interaction. The term “host plant” is used to denote a special connection between a given insect and a plant, but host plant is also a jargon term lacking precise meaning. In the case of Languria mozardi Latreille 1807 (Coleoptera: Erotylidae: Languriinae), the authors examined 17 manuscripts and found 48 plants, within seven families, identified as host plants for L. mozardi. Of these 48 plants, 13 are confirmed by the literature as developmental hosts. Many inadequately documented L. mozardi-plant associations have been referenced repeatedly in the literature, and the authors' aims are to clarify these relationships.

The incorporation of natural, non-crop vegetation in and around farmlands is a common practice in many agroecosystems, and may provide benefits both for production and conservation of biological diversity. In coffee agroecosystems, non-crop vegetation is routinely incorporated in the form of shade trees or forest habitat in and around coffee plants. In order to assess the importance of adjacent forest habitat to Hymenoptera associated with coffee farms, we sampled Hymenoptera on twelve coffee farms in the Tarrazú region in the central highlands of Costa Rica. Six of the farms were adjacent to forest habitat, and six were spatially isolated from forest; farms were sampled in both the dry (flowering) and the rainy (non-flowering) seasons. On adjacent farms, Hymenoptera samples taken in coffee and forest habitat were also compared. Finally, we also conducted pollinator observations in each type of farm, comparing Hymenoptera visitors to coffee plants in adjacent vs. isolated farms. Our results revealed an interaction in hymenopteran diversity between farm isolation and season, suggesting that both forest and coffee habitats play important roles at different times for Hymenoptera, especially bees.
