Caryophyllene-6,7-epoxide and caryophyllene-6,7-episulfi de can be easily synthesized from -caryophyllene by autoxidation or episulfi dation. The bioactivities of -caryophyllene and its derivatives were investigated against the subterranean termite Reticulitermes speratus Kolbe. The antifeedant, feeding, and termiticidal activities of each compound were tested using no-choice, dual-choice, and ...

Among the facultative bacteria capable of growth on mesquite wood which were isolated from the asceptically dissected hind-gut of the termite Reticulitermes hesperus were two strains of Bacillus cereus, one strain each of Arthrobacter, Alcaligenes and Serratia, and a very small Gram-negative fermentative rod. The B. cereus strains, the Serratia marcescens strain and the Arthrobacter sp. grew we...

In this paper an extended robust independent components analysis algorithm based on cumulants is applied to identify vibrational alarm signals generated by soldier termites in southern Spain (reticulitermes grassei), measured using low cost equipment. A seismic accelerometer is employed to strongly characterize these acoustic emissions. To support the proposed technique, vibrational signals fro...

Brown rot fungus Fibroporia radiculosa (Peck) Parmasto grown in decayed wood and non-wood material, potato dextrose agar (PDA) media, deterred Reticulitermes speratus (Kolbe) feeding. Decayed wood and PDA media were extracted and tests were performed to assess termite feeding behavior towards the extracts. We found that the extract from PDA media also suppressed termite feeding, although it did...

Seven termite species (Isoptera) from five families were tested for disease susceptibility against the entomopathogenic fungus Metarhizium anisopliae using a standard protocol: Mastotermes darwiniensis (Mastotermitidae), Hodotermopsis sjoestedti (termopsidae), Hodotermes mossambicus (Hodotermitidae), Kalotermes flavicollis (Kalotermitidae), Reticulitermes flavipes and Prorhinotermes canalifrons...

The symbiotic relationship of termites and their eukaryotic and prokaryotic gut microbiota is a focal point of research because of the important roles symbionts play in termite nutrition. The use of molecular methods has recently provided valuable insights into the species diversity and the roles of microorganisms in the guts of termites. This paper provides a review of the current knowledge of...
