Fipronil is the active ingredient in many liquid termite control products---the most common is Termidor. March 16, 2004. Termite workers were collected from monitoring stations, mud tubes and wood debris; placed into vials containing 95% ethanol; and stored at −20°C until DNA extraction. These colonies were occupying mud tubes on the foundation wall, present in structural elements, or both. Bagnères We also checked other areas in the yard containing wood debris, stumps, wood piles, and other materials at least twice before treatment. Genotypes were scored by comparing the fluorescently labeled PCR products to size standards by using GeneProfiler version 3.56 (BD Biosciences Bioimaging, Rockville, MD). The dark irregular shape present in the pretreatment panel depicts a colony that was infesting the structure. Finally, we considered colonies located in the outer ring of monitors or in the natural areas to be untreated colonies. The untreated colonies thus serve as important controls for our ability to attribute apparent colony-level effects to the fipronil treatment, because such colonies provide the baseline for the likelihood of not redetecting colonies due to reasons other than elimination by insecticide treatment, including a failure of the sampling method to detect colonies that are present, relocation of colonies out of the sampled area, or death from natural causes. N. Y. 1 and 2). H. X. These houses were part of a larger group of 20 houses studied by Parman and Vargo (2008) to investigate subterranean termite colony abundance and density on residential properties. Taurus SC — Most Popular. All treatments were done in accordance with the label, including trenching and rodding around foundation walls, as well as drilling slabs, hollow blocks, walkways, and porches, where appropriate. Termidor … In these respects, these two nonrepellent liquid termiticides have effects much like baits. Termidor controls all types of termites including subterranean, formosan, and drywood termites. Husseneder 2). As with imidacloprid, fipronil is fatal for honeybees, and should never be used in their foraging areas. S. Larger circles and enclosed shapes in gray represent colonies not known to be infesting the structure. Its all the same thing. 2009) and in Coptotermes spp. It means that, when a worker touches the powder, it becomes a “carrier”, delivering Termidor termite dust to other termites … Black arrows indicate colonies present before treatment and found again at the later time points. First, foragers contacting treated soil may transfer sufficient amounts of fipronil throughout the colony to kill all members. Fipronil is the main ingredient in many brand name products such as Regent and Termidor which are used as a traditional form of barrier treatment for termite control. Su Fipronil termite treatment. Traditionally, the goal of such a treatment is to create a continuous chemical barrier that excludes termites in the ground from entering a building. The National Pesticide Information Center based at Oregon State University states that the pesticide … Mean number (±SE) of subterranean termite colonies found in mud tubes on the structure, in monitors located within 0.5 m from the foundation wall (inner monitors), and in monitors located further from the structures (2–20 m from the foundation wall; outer monitors) before treatment and at four time points after treatment. 2008, Bagnères et al. Davis Subterranean termite activity at monitors (mean percent ± SE) located within 0.5 m from the foundation wall (inner monitors) and those further from the structures (2–20 m from the foundation wall; outer monitors) before treatment and at four time points after treatment. A.-G. None of the 11 treated colonies was found on or after the 90-d posttreatment sampling date and were presumed to be eliminated. In brief, the genotypes of the group of individuals comprising a sample were compared with all other groups collected from the same property by means of an exact test of genotypic differentiation by using GenePop on the Web (Raymond and Rousset 1995). N. We also use third-party cookies that help us analyze and understand how you use this website. Companies may … P. D. It contains 9.1% of fipronil which turns helpful for effective … However, there may be limitations on the distance over which fipronil treatment can affect subterranean termite colonies. 2003, Shelton and Grace 2003, Rust and Saran 2006, Tsunoda 2006, Haagsma and Rust 2007, Saran and Rust 2007, Spomer et al. It is also possible that some of these colonies migrated out of the study site and persisted outside of the monitored area. 1 and 2). Using molecular markers to track colonies in the field with both fipronil in the current study and imidacloprid in our previous study (Parman and Vargo 2010), we have shown that at least these two nonrepellent liquid termiticides can have strong colony-level effects on subterranean termites very similar to the effects of baits, severely suppressing colony populations and in many cases resulting in their elimination.
