Nootkatone Is a Repellent for Formosan Subterranean Termite (Coptotermes formosanus)

open access: yesJournal of Chemical Ecology, 2001
We examined the behavior of Formosan subterranean termites toward one of the components of vetiver grass oil, the roots of which manufacture insect repellents. We found nootkatone, a sesquiterpene ketone, isolated from vetiver oil is a strong repellent and toxicant to Formosan subterranean termites.

Hydroquinone Is Not a Phagostimulant for the Formosan Subterranean Termite

Journal of Chemical Ecology, 2005
It has been suggested that hydroquinone found in the labial glands of a number of termite species acts as a primary phagostimulating factor. We tested hydroquinone as a phagostimulant using workers from three colonies of the Formosan subterranean termite, Coptotermes formosanus, under both laboratory and field conditions. Hydroquinone at concentrations

Molting in Workers of the Formosan Subterranean Termite Coptotermes formosanus

Journal of Insect Physiology, 2008
The Formosan subterranean termite, Coptotermes formosanus, with its huge colonies, is a major urban pest in several southern states and Hawaii as well as in South Asia. Because of their cryptic nature (underground habitat) and very long life cycle, not much is known about molting in termite workers. In C.

Determination of Feeding Preference of Formosan Subterranean Termite (Coptotermes formosanus Shiraki) for Some Amino Acid Additives

open access: yesJournal of Chemical Ecology, 1996
A choice feeding lest using 21 amino acids was conducted to determine the feeding preference of Formosan subterranean termite, Coptotermes formosanus Shiraki, in the laboratory.

A comparison of tunnel geometry between the Formosan subterranean termite and the Asian subterranean termite (Blattodea: Rhinotermitidae)

Pest Management Science, 2023
AbstractBACKGROUNDStake surveys and in‐ground monitoring stations have been widely used to study field populations of many subterranean termite species, but thus far they have never been intercepted by the invasive Asian subterranean termite, Coptotermes gestroi (Wasmann), in southeastern Florida.

Hyperecdysonism in the Formosan Subterranean Termite and Eastern Subterranean Termite (Isoptera: Rhinotermitidae)

Journal of Economic Entomology, 2017
Effects of ecdysone, 20-hydroxyecdysone (20E), and an ecdysone agonist, halofenozide, were tested against the Formosan subterranean termite, Coptotermes formosanus Shiraki, and the eastern subterranean termite, Reticulitermes flavipes (Kollar), in a 12-d no choice assay. Approximately 22-26% of R. flavipes and C.

Toxicity of Seven Termiticides on the Formosan and Eastern Subterranean Termites

Journal of Economic Entomology, 2011
Using both topical application and substrate (sand) treatments the toxicities of seven new generation soil termiticides were evaluated to determine the LD50 and LC50 against two economically important subterranean termite species, eastern subterranean termite, Reticulitermes flavipes (Kollar), and Formosan subterranean termite, Coptotermes formosanus ...

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
