Water Transport byCoptotermes formosanus(Isoptera: Rhinotermitidae)
Environmental Entomology, 2014Subterranean termites are extremely vulnerable to desiccation, and high moisture makes their habitat and food favorable for survival and colony growth. Although there is a general perception that termites can manipulate moisture, documentation is surprisingly scanty with regard to how termites transport water and the factors that impact it.

Bulletin De La Société Entomologique De France, 2005 Contribution to the knowledge of termites of the genus Reticulitermes in the Bouches-du-Rhône (France) (Isoptera, Rhinotermitidae). The cartography of the four species of Reticulitermes in the Rhône delta has been completed.

The ontogeny of soldiers in Prorhinotermes simplex (Isoptera, Rhinotermitidae)
Insectes Sociaux, 2006The ontogeny of the soldier caste in Prorhinotermes simplex is studied with emphasis on the instar origin of soldiers, the duration of the presoldier stage, and changes in external anatomy during the soldier morphogenesis. The soldiers of different instar origin are compared morphometrically and by analysis of the soldier defensive secretion.

Termiticidal activity of boron dusts (Isoptera, Rhinotermitidae)
Journal of Applied Entomology, 1990AbstractMortality of Reticulitermes flavipes (Kollar) workers was evaluated 1, 2, 4, and 8 days after exposure to boron dusts. Mortality was most rapid after exposure to barium metaborate (Busan 11‐M1), followed by boric acid. Exposure to either of these two dusts resulted in 100 % mortality within 8 days.

Termites (Isoptera: Kalotermitidae, Rhinotermitidae, Termitidae) of Ecuador
Annales de la Société entomologique de France (N.S.), 2009Abstract Termites are an abundant and diverse group in the Neotropics with about 500 species representing 83 genera. The paucity of the termite fauna recorded from Ecuador is due, in part, to a lack of deliberate surveys. We revise the termite fauna of Ecuador and raise the number of species from 25 species to 72 based on our recent termite surveys. Of

Hermetically Sealed Baits for Subterranean Termites (Isoptera: Rhinotermitidae)
Journal of Economic Entomology, 2007Cellulose baits containing 0.5% hexaflumuron were hermetically sealed in a closed cell polyethylene sheet envelope and placed in soil to test their durability and efficacy against field colonies of the Formosan subterranean termite, Coptotermes formosanus Shiraki, or the eastern subterranean termite, Reticulitermes flavipes (Kollar).

The fluorescent alkaloid norharmane has been isolated from Reticulitermes termites and characterized by 1H NMR, UV/Vis, mass spectrometry, and gas chromatography/mass spectrometry. Microcoil 1H NMR spectroscopy allowed spectra to be obtained from mass-limited material, facilitating the identification of norharmane, which is the major component in ...

Journal of Economic Entomology, 2016
In termites, it is challenging to recognize the incidence of molting in workers because of their successive stationary molt, asynchronous molting among individuals, cryptic behavior, a soft and poorly sclerotized cuticle, and they immediately consume the shed exuvia of nestmates.

Cuticular permeability of two species of Coptotermes Wasmann (Isoptera: Rhinotermitidae)
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2003Cuticular permeability (CP) values of worker and soldier castes of Coptotermes formosanus Shiraki and Coptotermes vastator Light were determined using gravimetric techniques. Comparisons were made between castes, species, and between colonies of C. formosanus and C. vastator.

Trail-following behavior ofReticulitermes hesperus Banks (Isoptera: Rhinotermitidae)
Journal of Chemical Ecology, 1988The behavior ofReticulitermes hesperus Banks pseudergates (workers) was assessed on artificial trails containing different concentrations of sternal gland extract. On nongiadient trails, more pseudergates were recruited to trails of greater pheromone concentration, they traveled a greater distance without pausing, and their rate of locomotion increased
