Agonistic Behavior of the Termite Prorhinotermes canalifrons (Isoptera: Rhinotermitidae)

Journal of Insect Behavior, 2008
While intercolonial and interspecific agonism has been broadly documented in termites, detailed studies of individual behavior and its differentiation among castes are scarce. We studied the responses of non-reproductive castes of Prorhinotermes canalifrons (pseudergates, presoldiers, soldiers of different age and artificial intercastes) to conspecific

Dispersal Flights of the Formosan Subterranean Termite (Isoptera: Rhinotermitidae)

Journal of Economic Entomology, 2015
The Formosan subterranean termite, Coptotermes formosanus Shiraki, is a pest of major economic concern. This termite is particularly known for its tendency to establish populations in nonendemic areas via maritime vessels as well as human-aided transport of infested materials. The natural spread of this species after new introductions occurs in part by

Water Transport byCoptotermes formosanus(Isoptera: Rhinotermitidae)

Environmental Entomology, 2014
Subterranean 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.

The ontogeny of soldiers in Prorhinotermes simplex (Isoptera, Rhinotermitidae)

Insectes Sociaux, 2006
The 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, 1990
AbstractMortality 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.), 2009
Abstract 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

Morphology of the sternal gland in workers of Coptotermes gestroi (Isoptera, Rhinotermitidae)

Micron, 2006
The sternal gland is considered the only source of trail pheromones in termites. The morphology of the sternal gland was investigated in workers of Coptotermes gestroi using transmission and scanning electron microscopy. The results showed a small bilobed gland at the anterior part of the fifth abdominal sternite.

Hermetically Sealed Baits for Subterranean Termites (Isoptera: Rhinotermitidae)

Journal of Economic Entomology, 2007
Cellulose 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).

Isolation and Characterization of Norharmane from Reticulitermes Termites (Isoptera: Rhinotermitidae)

Journal of Economic Entomology, 2005
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 ...

Postecdysis Sclerotization of Mouthparts of the Formosan Subterranean Termites (Isoptera: Rhinotermitidae)

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.
