Emerald ash borer (Agrilus planipennis Fairmaire) is an invasive primary pest of North American ash (Fraxinus spp.) trees. Blue ash (F. quadrangulata) is less susceptible to emerald ash borer infestations in the forest than other species of North American ash. Whereas other studies have examined adult host preferences, we compared the capacity of emerald ash borer larvae reared from emerald ash...

Eight species of parasitic wasps were bred from various stages of five species of hesperiids viz. Thoressa evershedi (Evans), Pelopidas mathias (Fabricius), Udaspes folus (Cramer), Borbo cinnara (Wallace) and Caltoris sp. inhabiting Western Ghats, Kerala, India. One new species, Dolichogenidea kunhi Gupta & Kalesh, is described and illustrated from Kerala, India, and its relationship with close...

The beetle Octodonta nipae (Maulik) (Coleoptera: Chrysomelidae) is a serious invasive insect pest of palm plants in southern China, and the endoparasitoid Tetrastichus brontispae Ferrière (Hymenoptera: Eulophidae) is a natural enemy of this pest that exhibits great ability in the biocontrol of O. nipae. For successful parasitism, endoparasitoids often introduce or secrete various virulence fact...

A total of 16 genera and 68 species of Chalcididae of Vietnam are taxonomically treated. Thirteen new species are described; the remaining 55 species are keyed, redescribed or provided with a diagnosis. Among these 37 species and eleven genera are recorded for the first time from Vietnam. The thirteen new species are: Antrocephalus neogalleriae Narendran & van Achterberg, sp. n.; Brachymeria ne...

Many natural enemies employ plant- and/or herbivore-derived signals for host/prey location. The larval parasitoid Tetrastichus planipennisi Yang (Hymenoptera: Eulophidae) is 1 of 3 biocontrol agents currently being released in an effort to control the emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coloeptera: Burprestidae) in North America. To enhance its efficiency, allelochemicals th...

Increased utilization of all ceramic restorations for aesthetic consideration in combination with routine adult orthodontic practice has led to numerous clinical challenges. Obtaining adequate bond strength between the bracket and all-ceramic restoration damage surface during debonding procedure needs be better understood. This study analyzed texture color change glazed bracket-debonded CAD–CAM...
