Nonrandom Search Geometry in Subterranean Termites

Naturwissenschaften, 1995
[Extract] Studies of the organization of search in ants suggest that individual and colonylevel patterns are related to foraging ecology and may be adaptive [1, 2]. The organization of search in termites has received far less attention, in part because of their cryptic, subterranean foraging habits.

Geophone Detection of Subterranean Termite and Ant Activity

Journal of Economic Entomology, 2006
A geophone system was used to monitor activity of subterranean termites and ants in a desert environment with low vibration noise. Examples of geophone signals were recorded from a colony of Rhytidoponera taurus (Forel), a colony of Camponotus denticulatus Kirby, and a termite colony (undetermined Drepanotermes sp.) under attack by ants from a nearby C.

Adaptive evolution in subterranean termite antifungal peptides

Insect Molecular Biology, 2010
Abstract We identified and analysed mRNA sequences of two immune proteins from the subterranean termites Reticulitermes flavipes and Reticulitermes virginicus .

Time Trends in Mortality for Thiamethoxam and Fipronil Against Formosan Subterranean Termites and Eastern Subterranean Termites (Isoptera: Rhinotermitidae)

Journal of Economic Entomology, 2005
Time trends in mortality for the Formosan subterranean termite, Coptotermes formosanus Shiraki, and eastern subterranean termite, Reticulitermes flavipes (Kollar), were determined for thiamethoxam and fipronil. Filter paper treated with 50 ppm thiamethoxam led to >80% mortality in 2-4 d for R.

Comparison of Eleven Soil Termiticides Against the Formosan Subterranean Termite and Eastern Subterranean Termite (Isoptera: Rhinotermitidae)

Journal of Economic Entomology, 1990
Toxicities of 11 topically applied termiticides to the Formosan subterranean termite, Coptotermes formosanus Shiraki, and the eastern subterranean termite, Reticulitermes flavipes (Kollar) were determined. At LD50, deltamethrin was most toxic (0.12 and 0.01 μg/g for C. Formosan us and R.

Metabolism of chlorpyrifos-14C in the eastern subterranean termite

Bulletin of Environmental Contamination and Toxicology, 1975
Termites treated topically with chlorpyrifos-C readily absorbed the material and metabolized it to chlorpyrifos oxygen analog. There also was evidence for some dechlorination of chlorpyrifos to 3-dechlorochlorpyrifos. Subsequent metabolism of chlorpyrifos and chlorpyrifos oxygen analog to water-soluble metabolites proceeded slowly.

Interference competition in desert subterranean termites

Entomologia Experimentalis et Applicata, 1991
AbstractWe examined interspecific aggression between two subterranean termite species, Heterotermes aureus (Snyder) (Rhinotermitidae) and Gnathamitermes perplexus (Banks) (Termitidae). In laboratory tests with worker termites, neither species was the inherently superior fighter, but rather the outcome of interspecific encounters depended on the number ...

Development of Baits for Population Management of Subterranean Termites

Annual Review of Entomology, 2019
The objective of bait application envisioned by early researchers was to eliminate the source of infestation, the colony, but because of the lack of adequate evaluation tools, results of field trials with mirex baits in the 1960s were mostly inconclusive.

A Fluid Bait for Remedial Control of Subterranean Termites

Journal of Economic Entomology, 2015
A fluid bait, comprising α-cellulose and fine-ground phagostimulants (Summon Preferred Food Source) impregnated with 0.5% hexaflumuron (AI wt/wt) and mixed with 1% methylcel solution to yield 10% dry weight, was injected into simulated foraging galleries of Coptotermes formosanus Shiraki and Reticulitermes virginicus (Banks) for a laboratory efficacy ...
