Bagnères 2003, Shelton and Grace 2003, Rust and Saran 2006, Tsunoda 2006, Haagsma and Rust 2007, Saran and Rust 2007, Spomer et al. Gerard Effect of fipronil treatment on colonies of R. flavipes on eight residential properties in the Raleigh, NC, area. P. D. There is no Fipronil brand type A and Type B. In that study, activity at the monitors decreased by 67% over 2 yr. Fipronil is transferred among termite castes via the unique “Transfer EffectTM”. Between the 1- and 3-yr time points, monitors were checked four times per year and natural areas twice annually. . Taurus SC is a professional-grade termiticide with the active ingredient Fipronil and is used to control termites and various other insects around structures. These cookies do not store any personal information. To assess possible colony-level effects of fipronil, a commonly used nonrepellent termiticide, we conducted a field study of eight houses in the Raleigh, NC, area with infestations of the eastern subterranean termite Reticulitermes flavipes (Kollar) (Isoptera: Rhinotermitidae). Drywood Termite Control and Prevention Methods, Why You Should Avoid Relying on Post Construction Anti-Termite Treatment, A rather strange species of nasute termite, How drywood and subterranean termites differ. To distinguish among possible treatment levels, all colonies present before treatment were placed into one of three categories as described in Parman and Vargo (2010). J. W. In contrast, the untreated colonies were much more likely to be redetected, with 60% of the colonies found again after the 90-d sampling period. We installed an extensive grid of in-ground monitoring stations on each property (mean = 68.6 monitors per property) and collected samples from these stations as well as from mud tubes in the structure and wood debris in the yard for ≈6 mo. A.-G. This stands in contrast to our results with imidacloprid (Parman and Vargo 2010), in which 67% of the likely treated colonies survived after 2 yr, a survival rate very similar to the untreated colonies in that study (71%). S. A. You can manage or block these using your browser settings. The redetection rate of 60% of the untreated colonies in the current study was slightly lower than the 71% found in an earlier similar study we conducted using the same methods and in the same geographic region to evaluate the colony-level effects of imidacloprid (Parman and Vargo 2010). During the period between 90 d after treatment and the 1-yr mark, monitors were checked at least six times and natural areas at least twice. These authors found that most of the transfer occurred through contact and not trophallaxis. Warriner More costly than some … Cole In total, we detected 128 colonies present on the eight properties at the time of treatment, including those infesting the structures. A second potential mechanism by which fipronil may exert colony-level effects is direct contact of treated soil by most or all of a colony's foragers leading to eventual colony death over time due to attrition. C. B. Nicholson A. The inner ring consisted of monitors placed ≈0.5 m from the foundation wall and positioned 2–6 m apart. Locations and observed foraging areas of R. flavipes colonies on property HI before treatment and at four time points after treatment. It can be found in dust form that is blown into the tunnel systems of termites, gel for use in bait stations, and also as a liquid state. Su (2005) reported that only 25–35% of the foragers were killed by the treatment and suggested that portions of the colony located >5 m away from the treated area would be not be strongly affected, limiting colony wide impact on this species. Effective against termites as well as other pests. It appears to reduce the … (2007) who found a decline in active monitors within 2 m of the treatment zone in R. flavipes. 2003). Spomer Working with R. flavipes, Bagnères et al. Davis 2008), and the castes involved in transfer (Ibrahim et al. T. R. Finally, we considered colonies located in the outer ring of monitors or in the natural areas to be untreated colonies. R. A. J.-L. 1F2F3–4 and) and in the natural areas throughout the study (Figs. J. E. Fipronil is one of the newest names on the market for pest control, effective in the elimination of ants, roaches, termites, and other common pests. 2007) and liquid treatments (Parman and Vargo 2010). 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. Fipronil is a phenylpyrazole insecticide that disrupts central nervous system activity by blocking the γ-aminobutyric acid-gated chloride channel (Cole et al. Termidor (tm) is a relatively new insecticide with the active ingredient fipronil.There are a number of active labels for fipronil-based insecticides currently sold in the US including flea medications, a commercial agricultural insecticide called Regent, and of course Termidor for pests that damage structures like termites … Termidor … (2004). S1–S23, Contact versus feeding intoxication by fipronil in, Action of phenylpyrazole insecticides at the GABA-gated chloride channel. 2009) and can have activity on termite colonies beyond the immediate zone of treated soil (Potter and Hillery 2002, Osbrink and Lax 2003, Ripa et al. In China, two of three baited colonies of Odontotermes formosanus (Shiraki) stopped foraging in trees and bait stations after 120–150 days when fed 40 ppm fipronil … The reasons for the survival of these colonies are not clear. Davis Few of the 12 likely treated colonies were found during this period, although three (25%) were found repeatedly up to the end of the study. A.-G. This house received an exterior/localized interior perimeter treatment. Szalanski Colonies of R. flavipes in our study area tend to be localized with foraging areas generally not extending beyond five linear meters (Parman and Vargo 2008), although one of the treated colonies (property HI, Fig. Monitoring stations were constructed from 6 cm-wide polyvinyl chloride (PVC) tubing as described by Parman and Vargo (2008). Our findings show that fipronil treatment can have severe impacts on subterranean termite colonies in the field, with strong colony suppression probably resulting in colony elimination. 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. All of the colonies tracked for at least 1 yr after baiting—34 R. flavipes colonies and one R. virginicus colony—disappeared from the study and were presumed to be eliminated. N. Y. Details of the numbers of colonies found in and around each structure before treatment are given in Table 1. For any given property, monitors were installed in either a single day or over two consecutive days. Pichon The strong family structure of colonies in the study population, nearly all of which were founded by a monogamous pair of reproductives (Parman and Vargo 2008), together with the high genetic variability exhibited at Rf 24-2, with up to 36 alleles present in the local R. flavipes population (Parman and Vargo 2010), make colony identification straightforward and accurate. Clément Luppichini J. E. The substance is toxic to people and … Over the past dozen years or so, nonrepellent liquid insecticides with delayed toxicity have come to dominate the postconstruction termiticide market in most regions of the United States due to their high efficacy and low rates of treatment failures (Anonymous 2002, Potter 2004). D. M. Ripa Black arrows indicate colonies present before treatment and found again at the later time points. Fipronil is used in a wide variety of pesticide products, including granular products for grass, gel baits, spot-… The 90-d time period was represented by the sample collected closest to this data (range, 82–126 d after treatment). Termidor controls all types of termites including subterranean, formosan, and drywood termites. 1 and 2). We selected eight residential, stand-alone houses with active termite infestations in and around Wake County, NC. Wood debris in natural areas was checked semiannually for 3 yr. All 11 of the treated colonies (those attacking structures) disappeared within 90 d of treatment and were not found again. There has been no definitive evidence that the chemical leads to any types of birth defects. While quite effective in both knockdown and control, fipronil is classified as a class II moderately hazardous pesticide. 2009, Mulrooney and Gerard 2009), well above the 60 ppm rate of application. Gray larger circles and enclosed shapes represent colonies. There is growing evidence that at least some nonrepellent termiticides can be transferred among individuals within colonies (Ibrahim et al. In a recent study, we used a combination of microsatellite genotyping and intensive monitoring to assess colony-level effects of imidacloprid treatment in the field over a 2-yr period in central North Carolina (Parman and Vargo 2010). March 16, 2004. Given the intense sampling effort we undertook to find any workers of these colonies, including 11 or more inspections of all monitoring stations after the 90-d posttreatment date, the most likely explanation for the continued absence of these colonies was that they were eliminated by the treatment. R. A. These cookies will be stored in your browser only with your consent. 2007, Saran and Rust 2007, Spomer et al. Locations and observed foraging areas of R. flavipes colonies on property BW before treatment and at four time points after treatment. Our results showed the likely elimination of up to nine of 12 treated Reticulitermes spp. After the pretreatment period, many samples were analyzed at only two loci (Rf 24-2 and Rf 15-2), shown to be sufficient to determine colony affiliation in the study population (Parman and Vargo 2010), whereas others also were genotyped at Rf 21-1. . Taurus sc is a insecticide which is used for keeping termites away from your home. 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. Fipronil is used to control ants, beetles, cockroaches, fleas, ticks, termites, mole crickets, thrips, rootworms, weevils, and other insects. Fipronil termite treatment. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. In a study very similar to the present investigation but involving imidacloprid, we also found decreased activity of the inner monitors, although activity remained in some of those monitors throughout the 2-yr duration of the previous study (Parman and Vargo 2010). Fei 2009) and in Coptotermes spp. Wagner These authors suggested that any potential colony-level effects of fipronil would be limited to areas within 5 m of the site of treatment. It works by disrupting, and eventually disabling, the central nervous system of insects. (2003) on a fragment of the cytochrome oxidase II (COII) gene. HARRIS Termite Treatment and Mold Killer, 16oz Powder, Makes 1 Gallon Liquid Spray for Preventing, Controlling and Killing Termites, Wood Destroying Beetles, Carpenter Ants and More 4.3 out of 5 stars … Simms . Mulrooney It is telling that although we redetected most (60%) of the untreated colonies at least once after 90 d posttreatment, we failed to detect a single treated colony during this time. Ahmed Edward L. Vargo, Vincent Parman, Effect of Fipronil on Subterranean Termite Colonies (Isoptera: Rhinotermitidae) in the Field, Journal of Economic Entomology, Volume 105, Issue 2, 1 April 2012, Pages 523–532, https://doi.org/10.1603/EC11155. The dark irregular shape present in the pretreatment panel depicts a colony that was infesting the structure. Its all the same thing. We found that some 25% of the likely treated colonies survived and persisted throughout the study period. The outer ring of monitors was located ≈6 m outside of the inner ring, and in some cases, a third ring of monitors ≈6 m beyond the second ring was also installed. Characteristics of study properties and pretreatment sampling period. Fipronil is specially designed by biochemists to disrupt the central nervous system of termites that come in contact with the chemical; fipronil in high concentrations kills termites … In that study, colonies visiting >230 in-ground monitoring stations located near the foundation wall were baited and tracked for a 3-yr period. Anyway, scientists inform all homeowners, that they should use it only with a pest control specialist. Search for other works by this author on: Colony dynamics of the Formosan subterranean termite in a frequently disturbed urban landscape, Termite business keeps growing, pp. The chemical barrier created by this termite treatment remains in place for up to 10 years, keeping a home safe from termites, as well as from ants, centipedes, wasps, and roaches. We did extensive monitoring and sampling for 3 yr after treatment. The difference among treatments was due to the high detection frequency of the untreated colonies compared with the other two groups (P < 0.001 and P < 0.03 for treated and likely treated colonies, respectively; Fisher exact test), whereas there was no significant difference between the treated and likely treated colonies during this period (P > 0.10). We use cookies to enhance your experience. These results are consistent with those of Potter and Hillery (2002) who found a lack of R. flavipes activity within several meters of treated structures, and those of Ripa et al. It could be that although many workers in most of these likely treated colonies contacted the nearby treated soil, few or no workers in other likely treated colonies entered the treatment zone despite being active very close to it, thereby limiting the effects of the active ingredient on some colonies. Offers broad-ranging insect control. P. D. Evidence against this possible mechanism, at least in C. formosanus, comes from the results of the above-mentioned study by Su (2005) performed in extended foraging arenas in the laboratory. . It can certainly get into the ecological chain if birds eat insects that have been poisoned with the chemical (as happens when birds eat termite swarmers, for example).
