The Species ofRhimphoctona(Xylophylax) (Hymenoptera: Ichneumonidae: Campopleginae) Parasitizing Woodborers in China

Abstract

Four species of Rhimphoctona (Xylophylax) collected from P. R. China are reported. Two of them are new to science: Rhimphoctona (Xylophylax) maculifemoralis Luo and Sheng, sp.nov. reared from Tetropium castaneum (Linnaeus), and Rhimphoctona (Xylophylax) immaculata Luo and Sheng, sp.nov. One is a new record for China, R. (Xylophylax) rufocoxalis (Clément 1924) reared from T. castaneum (Linnaeus). The other is R. (Xylophylax) lucida (Clément 1924) reared from Monochamus saltuarius Gebier, Tetropium gabrieli Weise and Asemus sp. A key to species known in China is provided.

Identification of wood-boring beetles (Cerambycidae and Buprestidae) intercepted in trade-associated solid wood packaging material using DNA barcoding and morphology

“…and Rhimphoctona spp. are parasitoids of Tetropium and Monochamus larvae3031, the most commonly intercepted cerambycid genera in SWPM (based on Pest ID records). Data from this study may also inspire taxonomic revisions of groups for which few or no molecular data were previously available, such as the genus Arhopalus , which, based on our analysis, is not monophyletic.…”

Olfactory Cues from Pathogenic Fungus Affect the Direction of Motion of Termites, Coptotermes formosanus

“…Previously, the role of antennal chemical receptors in grooming behavior was demonstrated (Yanagawa et al 2009a ), and the sensillum chaetica was identified as the sensillum that responds to fungal odor by single sensillum recordings (SSR). However, in the same study, it was indicated that there were some other potential sensilla which can perceive odor (Yanagawa et al 2010 ). In the present study, our SEM and TEM image confirm the sensilla basiconica, which are adjacent to a sensillum capitulum, a chemo-receptor sensillum (Fig.…”

“…All termites were placed in a Petri dish (35 × 15 mm) and covered with an open lid cardboard box during the experiments to maintain dim lighting while still allowing photographs to be taken without disturbing the termites. The number of mutual contacts between termites was counted to estimate grooming because the duration of grooming behavior varied, and it was difficult to classify this behavior (Yanagawa et al 2010 , 2011a ). After a 15-min interval to acclimate termites, the number whose mouth parts contacted other individuals was counted every 30s for 15 min by using digital photographs.…”

“…Coptotermes formosanus tends to avoid pathogen odors, yet the termites approach and groom exposed nestmates to remove pathogens from their bodies (Yanagawa et al 2012 ). Recent studies show that termite grooming is a context-dependent behavior, as the frequency of grooming reflects the termites’ ability to identify the microbial contamination of their nestmates (Yanagawa et al 2010 , 2011a ). The conidia of the K3 strain are removed effectively from the termite cuticle via mutual grooming (Yanagawa et al 2008 ) even though conidial odors elicit clear avoidance behavior in C. formosanus (Yanagawa et al 2012 ).…”

Hyménoptères parasites (Ichneumonoidea) capturés au piège à vitre dans le domaine du Rond-Chêne (Esneux, Province de Liège) et focus sur 3 espèces de Xorides Latreille (Ichneumonidae : Xoridinae) présents en Belgique

“…Note : Les femelles se reconnaissent notamment à leurs coxas postérieures rouges et à la longueur de leur ovipositeur qui égale celle des tibias postérieurs. En Chine, où l'espèce est également présente, elle parasite le Cerambycidae Tetropium castaneum (Linnaeus, 1758) (Luo & Sheng, 2010). Ce longicorne est également bien présent chez nous (Muylaert, 1990) ; c'est une espèce polyphage sur conifères, notamment l'épicéa (Villiers, 1978).…”
