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.

Location of Food Sources by Subterranean Termites

Environmental Entomology, 1980
Chihuahuan desert subterranean termites, Gnathamitermes tubiformans (Buckley) and Amitermes wheeleri (Desneux) readily located surface foods but failed to utilize buried foods of the same type. The termites attacked both natural cowdung pats and artificial(polyurethane) cowdung pats at the same rate as estimated by holes chewed through plastic film ...

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 ...

SUBTERRANEAN TERMITE STUDIES IN SOUTHERN ONTARIO

The Canadian Entomologist, 1968
AbstractA cooperative project between Forest Products Laboratories in the United States and Canada, initiated in 1966 to study the control effectiveness of an insecticide-treated termite attractant, is reported. It represents a bait method of control being developed to eradicate relatively large pockets of infestation.Wooden bait blocks decayed by ...

A Strain of the Fungus Metarhizium anisopliae for Controlling Subterranean Termites

Journal of Economic Entomology, 2005
Alates of the Formosan subterranean termite, Coptotermes formosanus Shiraki, collected after swarming in 2002 died within 48 h, and the cadavers were visibly infected with a fungus. Fungi were picked from the cadavers, transferred to media, and ultimately isolated to purity.
