Effect of Pentoxifylline on Chitinolytic Enzyme Activity in the Eastern Subterranean Termite (Isoptera: Rhinotermitidae)
A two-molecule chitinolytic enzyme system (endoand exo-chitinase) hydrolyzes and degrades the chitin polymers. Therefore, it is imperative to discover novel compounds for inhibiting chitinolytic enzymes to prevent insect growth. This research examined the effect of pentoxifylline (a dimethylxanthine chitinase inhibitor) on inhibition of endoand exo-chitinolytic enzyme activities in eastern subt...
متن کاملFactors that Influence Tunneling in the Eastern Subterranean Termite, Reticulitermes flavipes (Kollar) (Isoptera: Rhinotermitidae)1
Although subterranean termite (Isoptera: Rhinotermitidae) foraging behavior involves the construction of gallery systems in soil, few studies have examined how colony size or soil environmental factors influence rates of construction and morphology of gallery systems. In this study, we investigated the effects of soil texture, soil moisture, and termite density on the rate of tunnel constructio...
متن کاملCold tolerance of the eastern subterranean termite, Reticulitermes flavipes (Isoptera: Rhinotermitidae), in Ontario.
We characterized the cold tolerance of natural populations of the Eastern subterranean termite (Reticulitermes flavipes (Kollar) [Isoptera, Rhinotermitidae]) in southwestern Ontario, Canada. We measured cold tolerance in workers from six colonies of termites established from Pelee Island in Lake Erie, and Point Pelee National Park. The mean critical thermal minimum, at which termites entered ch...
متن کاملToxicity and in vitro metabolism of t-permethrin in eastern subterranean termite (Isoptera: Rhinotermitidae).
Toxicity and metabolism of t-permethrin were evaluated in two colonies (UF and ARS) of the eastern subterranean termite, Reticulitermes flavipes (Kollar), collected in Gainesville, FL. The UF colony (LC50 = 1.86 micrograms per vial) was approximately twofold more tolerant of t-permethrin than the ARS colony (LC50 = 0.89 microgram per vial) at the LC50. The synergists piperonyl butoxide and S,S,...
متن کاملReticulitermes malletei (Isoptera: Rhinotermitidae): a valid Nearctic subterranean termite from Eastern North America
The taxonomic status of Reticulitermes Holmgren in North America has been in need of revision for years, but because of morphological ambiguity, traditional morphological identification of Reticulitermes species has always been difficult and unreliable. Analysis of termites, applying non-morphological genetic comparisons of mitochondrial DNA from numerous populations across North America, has i...
