Campbell 1997). However, posttreatment results reflected a significant reduction of ticks on mice throughout the treatment period. 1997). Finally, infection rates in flagged nymphal ticks for both B. burgdorferi and Anaplasma phagocytophilum were reduced by 67 and 64%, respectively, after only 2 yr of treatment. Relative use of bait boxes was determined as in the previous 2 yr, by recording use data on a total of 200 boxes located on 35 properties. Relative use for these boxes was 88 and 93% for August and September, respectively. Gage Defensins from the tick Ixodes scapularis are effective against phytopathogenic fungi and the human bacterial pathogen Listeria grayi Miray Tonk , Alejandro Cabezas-Cruz , James J Valdés , Ryan OM Rego , Tereza Chrudimská , Martin Strnad , Radek Šíma , Lesley Bell-Sakyi , Zdeněk Franta , Andreas Vilcinskas , Libor Grubhoffer , and Mohammad Rahnamaeian The CDC reported over 30,000 new cases of the disease in 2016 alone, the majority of which were contracted in the summer months, which is when ticks are most likely to bite humans. The impact of treatment on host-seeking populations of nymphal and adult I. scapularis was evaluated. . 2001). were performed June through September all 3 yr. No nymphs and only two engorged larvae (one mouse in August and one mouse in September) were recovered from mice in the fipronil-treated area in 1999 (Fig. In 2000, 31 additional properties (orange dots) received Protecta Jr. fipronil-treated bait boxes (new areas, 44 total treated properties). Epub 2017 Nov 27. compared with the untreated control areas (Fig. These observations underscore the need for an acaricide with considerable residual activity and adequate potency to protect mice from tick infestation. J. F. Schulze received 125 fipronil-treated bait boxes. Integrated Control of Nymphal Ixodes scapularis: Effectiveness of White-Tailed Deer Reduction, the Entomopathogenic Fungus Metarhizium anisopliae, and Fipronil-Based Rodent Bait Boxes. A total of 11 host-seeking nymphs (four nymphs in 2000 and seven in 2001) were collected on the 13 properties on Nauyaug Pt. A total of 6,428 trap nights resulted in 1,750 captures representing 1,225 individual P. leucopus. C. P. Stevenson Ewing In addition, fipronil has the characteristic of displacing mechanically to areas of the skin far from the site of treatment along with low percutaneous passage (Cochet et al. For full access to this pdf, sign in to an existing account, or purchase an annual subscription. As the deer feed, they are passively treated with an acaricide for controlling ticks. Ginsberg Burgdorfer Rapid onset of activity is important in reducing the feeding activity of ticks, thereby reducing the possibility of transmission of infections. . Mannelli The number of questing adults flagged on Nauyaug Pt. Bosler N. Zultkowsky N. S. In May 2000, six properties located on the northern-most part of the island and an additional 25 properties near the center of the island received fipronil-treated bait boxes (designated New Areas). T. N. K. L. 1998). 3C) with 6.3 ticks per mouse (Fig. ; only 10.3% became infected during the treatment period compared with 42.9% during the pretreatment period (P = 0.0187). Hyde K. L. W.E. Strategies for reducing the risk of Lyme borreliosis in North America. In an animal model of another tick-borne disease, Rocky Mountain spotted fever, antibiotic prophylaxis appeared to delay but not prevent infection.4 Antimicrobial therapy for the prevention of Lyme disease after I. sca… Dolan MC, Schulze TL, Jordan RA, Schulze CJ, Ullmann AJ, Hojgaard A, Williams MA, Piesman J. J Med Entomol. 2019 Mar 7;13(3):e0007210. Southeastern and south-central United States. Schulze In 1999, initial treatment with fipronil began on 17 May, and at 4-wk intervals each box was rebaited with one to two Detex bait blocks as needed, and the wick was replenished with 2–3 ml of fipronil formulation as needed throughout the trial. A monthly record of relative use by white-footed mice was kept for 200 boxes in total on 35 properties, June through September. One might be concerned that using a food lure in bait boxes might potentially increase rodent populations. J. . D. R. Passive application of fipronil significantly reduced the infection rate of Borrelia burgdorferi among white-footed mice by 53%. 4B) and 0.25 (Fig. . Boxes were spaced ≈10 m apart along the interface of maintained landscaping (predominantly lawn) with woodlot, stonewall, or scrub brush consisting of both native plants and feral cultivars to specifically target mouse/tick habitat (Maupin et al. (A) Average ticks per mouse in 1999 for Nauyaug Pt. Efficacy of a low dose fipronil bait against blacklegged tick (Ixodes scapularis) larvae feeding on white-footed mice (Peromyscus leucopus) under laboratory conditions. 2. Parasit Vectors. . Madigan declined within the first month after placement of the bait boxes on 13 properties in May 1999, and remained extremely low through September 2000. Peavey 3C) resulted in a slight increase in the number of infested mice (12%), and the number of ticks/mouse (2.8) (Fig. Upon replacement of these boxes (30 July 2001) with the original prototype, a modified Protecta Jr. bait box, no ticks were collected from 54 P. leucopus trapped during August and September 2001 (Figs. When a diagnosis of human granulocytic anaplasmosis is suspected, treatment should never be delayed to await laboratory confirmation. 1981, Maupin and Piesman 1994, Panella et al. Beard 3 and 4) among captured mice indicate a high level of host-targeted control. J. Fish Due to varying vegetation type and density of flagged properties, number of tick(s) per time of effort was used as a standard measurement to determine tick densities. During August from 1999 to 2001, five-fifths untreated sites had questing larvae. Shower, shampoo, and put on clean clothes after … T. N. J. F. Individual properties varied from 1/10 to 2.23 hectares. W. L. A record of relative use by white-footed mice was kept for each box during the trial. Malan Overall results on fipronil-treated properties demonstrated a nearly 80% reduction of I. scapularis nymphal tick populations after the first year of treatment and a 96% reduction over 2 yr. 1985, Slajchert et al. J. K. . M. C. All 1,700 bait boxes contained wicks treated with 0.75% (AI) fipronil and two Detex monitoring bait blocks. Solberg Ticks matching this description were recovered from treated areas only. K. III However, it is not known whether antimicrobial agents can effectively cure incubating Borrelia burgdorferi infection. Ticks Tick Borne Dis. Ixodes scapularis is the main vector of Lyme disease in North America. L. E. Marc C. Dolan, Gary O. Maupin, Bradley S. Schneider, Christopher Denatale, Nick Hamon, Chuck Cole, Nordin S.

Hutchison 4C). (1998) reported comparable results by using a similar permethrin-treated bait tube technology on woodrat reservoirs and Lyme disease vectors in California. 2020 Jan;80(1):127-136. doi: 10.1007/s10493-019-00452-7.

Ixodes ricinus usually are found on dogs only singly or in small numbers. 1996, Stafford et al. Of primary interest are those methods that focus on targeting the hosts of I. scapularis. Posttreatment data recorded for June 2001 (Fig. 2B) was used from 15 May to 25 July 2001. Falco J. F. Spielman During the second year, a total of 4 liters (30 g) of 0.75% (AI) fipronil was used to treat 315 bait boxes bimonthly. The number of nymphs per minute for the New Areas during 2001 was reduced by 68% (95 nymphs, 0.35 nymphs per minute, 8% infected with Bb) (P < 0.001).
