| cyclic co(2) release in cryptotermes cavifrons banks, incisitermes tabogae (snyder) and i. minor (hagen) (isoptera: kalotermitidae). | co(2) release patterns of three drywood termite species were investigated using flow-through respirometry techniques. eight hours of real-time co(2) release data were recorded for pseudergates of cryptotermes cavifrons banks, incisitermes minor (hagen), and i. tabogae (snyder) at 20-40 degrees c. cyclic release of co(2) was observed in 20-90% of c. cavifrons, 70-100% of i. tabogae, and 87-100% of i. minor pseudergates. variability of the recordings (calculated as the coefficient of variability o ... | 2001 | 11423337 |
| nesting ecology and cuticular microbial loads in dampwood (zootermopsis angusticollis) and drywood termites (incisitermes minor, i. schwarzi, cryptotermes cavifrons). | termites form one-piece nests in wood that can vary in their moisture content and degree of decomposition, and thus microbial richness. to estimate the microbial load of nests and the potential risk they pose for colony members, we quantified the number of microbes in the nest and on the cuticle of the dampwood termite, zootermopsis angusticollis, and three drywood termites, incisitermes minor, i. schwarzi, and cryptotermes cavifrons. the number of colony forming units (cfus) cultured from nest ... | 2003 | 15841247 |
| analysis of extensive [fefe] hydrogenase gene diversity within the gut microbiota of insects representing five families of dictyoptera. | we have designed and utilized degenerate primers in the phylogenetic analysis of [fefe] hydrogenase gene diversity in the gut ecosystems of roaches and lower termites. h(2) is an important free intermediate in the breakdown of wood by termite gut microbial communities, reaching concentrations in some species exceeding those measured for any other biological system. the primers designed target with specificity the largest group of enzymatic h domain proteins previously identified in a termite gut ... | 2012 | 21935609 |
| anaerobic carbon monoxide dehydrogenase diversity in the homoacetogenic hindgut microbial communities of lower termites and the wood roach. | anaerobic carbon monoxide dehydrogenase (codh) is a key enzyme in the wood-ljungdahl (acetyl-coa) pathway for acetogenesis performed by homoacetogenic bacteria. acetate generated by gut bacteria via the acetyl-coa pathway provides considerable nutrition to wood-feeding dictyopteran insects making codh important to the obligate mutualism occurring between termites and their hindgut microbiota. to investigate codh diversity in insect gut communities, we developed the first degenerate primers desig ... | 2011 | 21541298 |
| identification of termite species by the hydrocarbons in their feces. | blends of abundant cuticular hydrocarbons are species-specific for termites (isoptera) and can be used to identify a given taxon without the diagnostic castes, soldiers or adults. we demonstrate that hydrocarbon extracts of termite fecal pellets from damaged wood can also be characterized and used to identify termites responsible for damage, even though termites are no longer present or easily recovered. in structures infested by drywood termites, it is common to find fecal pellets, but difficul ... | 2005 | 16132216 |
| influence of environmental factors on activity patterns of incisitermes minor (isoptera: kalotermitidae) in naturally infested logs. | acoustic emission (ae) activity patterns were measured from seven loquat [eriobotrya japonica (thunb.) lindl.] logs, five containing live western drywood termite [incisitermes minor (hagen)] infestations, and two without an active drywood termite infestation. ae activity, as well as temperature, were monitored every 3 min under unrestricted ambient conditions in a small wooden building, under unrestricted ambient conditions but in constant darkness, or in a temperature-controlled cabined under c ... | 2013 | 23448049 |
| seasonal and daily patterns in activity of the western drywood termite, incisitermes minor (hagen). | activity of colonies of the western drywood termite, incisitermes minor, was measured with acoustic emission (ae) technology in five loquat (eriobotrya japonica) logs. termite activity, whether it was feeding, excavation or movement, was monitored for 11 months under ambient conditions in a small wooden structure maintained at the university of california richmond field station. ae, temperature, and humidity data were measured in 3-minute increments. termite activity was greater during the warme ... | 2011 | 26467834 |
| morphology and molecular phylogeny of staurojoenina mulleri sp. nov. (trichonymphida, parabasalia) from the hindgut of the kalotermitid neotermes jouteli. | staurojoenina is a large and structurally complex genus of hypermastigont parabasalians found in the hindgut of lower termites. although several species of staurojoenina have been described worldwide, all staurojoenina observed to date in different species of north american termites have been treated as the same species, s. assimilis. here, we characterize staurojoenina from the north american termite neotermes jouteli using light microscopy, scanning electron microscopy, and phylogenetic analys ... | 2013 | 23398273 |
