fipronil for termites

fipronil for termites

This chemical is quickly becoming a favorite amongst homeowners and commercial applicators alike for termite treatment, but it is also used for controlling cockroaches, ants, ticks, and fleas, among others. Fipronil baits had successfully suppressed termite activity of fungus-growing termites in the field in China and Pakistan. The dark irregular shape present in the pretreatment panel depicts a colony that was infesting the structure. Although it is likely that these colonies were exposed to the treated soil, it is impossible to know for certain whether foragers from these colonies contacted the treated area. All 11 of the treated colonies—the colonies known to be infesting structures and were targeted by termiticide application—went undetected within 90 d of treatment and were not detected again during the 3-yr study period. Termidor is completely undetectable by termites and once termites touch it they contact, ingest and spread the termiticide until it eliminates the entire colony. Samples were first identified to species using the polymerase chain reaction (PCR)-restriction fragment length polymorphism method of Szalanski et al. In that study, activity at the monitors decreased by 67% over 2 yr. Small open circles represent in-ground monitoring stations. Mulrooney 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 works by disrupting, and eventually disabling, the central nervous system of insects. Fipronil is commonly used to control ants, beetles, cockroaches, fleas, ticks, termites, mole crickets, thrips, rootworms, weevils, and other insects Fipronil is used in a wide variety of pesticide products … In our view, the most likely explanation for our failure to redetect any treated colonies during the intensive 3-yr monitoring period is that they were eliminated, although we cannot exclude the possibility that some of the treated colonies persisted after treatment with greatly reduced population sizes and were not encountered again. Fipronil was first registered for use in the United States in 1996. In our previous study on colony-level effects of imidacloprid treatment, we also saw about a 67% decrease in the activity of the inner monitors (Parman and Vargo 2010). P. D. Bagnères According to the National Pesticide Information Center at Oregon State University, Fipronil is an insecticide used to control many common insect pests including ants, termites, beetles, … (2007) found activity of the eastern subterranean termite ceased in monitoring stations located 2 m from the site of fipronil treatment, and Potter and Hillery (2002) found that fipronil treatment affected termites of this same species occupying monitoring stations up to 4 m away from the treated area. We installed monitors around the structures and in the yard areas between 26 April 2001 and 9 April 2002. Here, we use similar methods to determine the colony-level effects of fipronil treatment (Termidor) on subterranean termites infesting houses in North Carolina. The stations were inserted into prebored holes in the ground and covered at ground level with a PVC cap. (Ibrahim et al. Clément Spomer H. X. We installed an average of 68.6 ± 25.2 monitors on each property (range, 41–121). Ibrahim We also use third-party cookies that help us analyze and understand how you use this website.

It is a concentrated insecticide solution that is used to repel and kill various outdoor … 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. The environmental effects of fipronil are a bit more severe. As we noted in our previous studies of colony level effects of baiting (Vargo 2003) and liquid application of imidacloprid (Parman and Vargo 2010), our ability to detect the continuing presence of a colony depends on collecting samples of individuals from that colony in wood debris and monitors. 1 and 2). T. L. 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. N. A. In addition, extensive testing by the US Dept of Agriculture - Forestry … Characteristics of study properties and pretreatment sampling period. . We genotyped all samples by using microsatellite markers to identify the number and locations of colonies present on each property. 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. Su This website uses cookies to improve your experience while you navigate through the website. Malik It contains 9.1% of fipronil which turns helpful for effective … We used the PCR conditions described by Vargo (2000) and Dronnet et al. In this study, we used molecular markers to genetically “fingerprint” colonies so that their fate could be tracked after termiticide application. Proper use and storage of fipronil is essential in order to minimize the dangers to nature, the environment, animals, and humans. Black arrows indicate colonies present before treatment and redetected again at the later time points. For any given property, monitors were installed in either a single day or over two consecutive days. More costly than some … These colonies were presumed to be eliminated. In both cases, there was a clear effect of insecticide treatment on colonies; all of the structures were termite free within 90 d, and 20 of the 23 treated colonies disappeared from the study areas altogether, probably because they were eliminated. B. M. Bagnères These authors found that most of the transfer occurred through contact and not trophallaxis. But opting out of some of these cookies may affect your browsing experience. R. A. J. Jordon, J. Carlson, T. Juba, and P. Labadie provided valuable assistance in the field and laboratory. C. This work was supported by funds provided by BASF. . S. A. 2008), the ratio of recipients to donor (Spomer et al. We recorded whether individuals from a colony were detected at each time interval. Additional support for colony-level impact of fipronil comes from field observations indicating that fipronil can affect termites outside the immediate treatment zone. The substance is toxic to people and … It works by disrupting, and eventually disabling, the central nervous system of insects. Fipronil is the active ingredient in many liquid termite control products---the most common is Termidor. This house received an exterior/localized interior perimeter treatment. P. N. Y. 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. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. 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. Houses were treated using Termidor SC at the label rate of 0.06% by a commercial licensed pest management professional. … Termidor termite control is been tested on more than 250 different insect pests on crops and almost 40% of all the produced fipronil is used for crop pest control. 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. 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. A.-G. We are grateful to S. Taylor and W. Keith (both Capital Pest Services), J. Lynn (Surety Exterminating Company), and D. Harris (Economy Exterminators) for locating and treating the study houses. Small open circles represent in-ground monitoring stations. 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. In the past decade, three non-repellent compounds have been regis-. March 16, 2004. While older products available in the market are typically repellent to termites and other insects, FIPFORCE Aqua containing fipronil is a totally unique molecule in that its mode of action is non … Fipronil is a broad use insecticide that belongs to the phenylpyrazole chemical family. S1–S23, Contact versus feeding intoxication by fipronil in, Action of phenylpyrazole insecticides at the GABA-gated chloride channel. This Phenylpyrazole family insecticide packs a … There has been no definitive evidence that the chemical leads to any types of birth defects. Riegel It is also possible that some of these colonies migrated out of the study site and persisted outside of the monitored area. Houses were treated with either a full treatment (n = 5) or exterior/localized interior treatment (n = 3).

The active ingredient in Termidor is a chemical called fipronil, which works by blocking receptors in the brains and nervous systems of living organisms. We genotyped the pretreatment samples to determine colony affiliation as described below (see DNA Analysis for Termite Colony Affiliation) and then made maps of each property showing the locations of all active colonies present at the time of treatment (Figs. The "transfer effect" of Termidor has been observed through controlled scientific testing using C14 radio labeled fipronil on live termites. Henderson 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 … Gerard Finally, we considered colonies located in the outer ring of monitors or in the natural areas to be untreated colonies. The idea is that termites … Every day we get exposed to harmful chemicals such as Fipronil without realizing it. Samples of any termites encountered were collected and held in vials containing 95% ethanol at −20°C until DNA extraction. 2007) and liquid treatments (Parman and Vargo 2010). In addition, termite activity close to the foundation walls dramatically decreased in the case of imidacloprid and ceased altogether in the case of fipronil. It means that, when a worker touches the powder, it becomes a “carrier”, delivering Termidor termite dust to other termites … These conclusions are consistent with our findings. Thus, it is possible that some colonies survived the treatment and continued to persist on the property but we failed to find them again after the pretreatment sampling period because they were not encountered again in either the monitors or wood debris. 1993). The main active ingredients in the new nonrepellents are fipronil (Termidor, BASF Corp., Research Triangle Park, NC), imidacloprid (Premise, Bayer Corporation Specialty Products, Kansas City, MO; several generic products), chlorfenapyr (Phantom, BASF Corp.), and chlorantraniprole (Altriset, DuPont Crop Protection, Wilmington, DE). Simms These authors suggested that any potential colony-level effects of fipronil would be limited to areas within 5 m of the site of treatment. The maximal distance from the house and therefore the treatment zone in these four colonies ranged from 6 to 13.5 m. As noted, all active workers from these colonies disappeared by 90 d after treatment, indicating that at least in some cases, field applications of fipronil can affect foragers located >10 m from the treatment zone. Offers broad-ranging insect control. . The application of liquid termiticides to the soil has been the mainstay of subterranean termite control for many decades. The houses used in the current study averaged (± SD) 378.9 ± 253.7 m2 (range, 182–789 m2) and were situated on a mean lot size of 2,747 ± 2474 m2 (range, 648-7568 m2). They ranged in age from 6 to 49 yr (mean = 23.4 ± 17.2 yr). For commercial re-use, please contact journals.permissions@oup.com.
