“…17,18 A single springtime application of synthetic acaricide timed to coincide with nymphal emergence can significantly reduce the number of questing ticks for several months. 19 Natural, plant-based acaricides, which may be more acceptable to some homeowners 17,20,21 can also reduce the abundance of I. scapularis nymphs; however, their efficacy begins to wane after several weeks. 19,22,23 Knowledge regarding the time period when humans have a high risk of acquiring infection could therefore be used to target the timing of application of conventional or natural acaricides.…”

Abstract. Lyme disease (Borrelia burgdorferi infection) is the most common vector-transmitted disease in the United States. The majority of human Lyme disease (LD) cases occur in the summer months, but the timing of the peak occurrence varies geographically and from year to year. We calculated the beginning, peak, end, and duration of the main LD season in 12 highly endemic states from 1992 to 2007 and then examined the association between the timing of these seasonal variables and several meteorological variables. An earlier beginning to the LD season was positively associated with higher cumulative growing degree days through Week 20, lower cumulative precipitation, a lower saturation deficit, and proximity to the Atlantic coast. The timing of the peak and duration of the LD season were also associated with cumulative growing degree days, saturation deficit, and cumulative precipitation, but no meteorological predictors adequately explained the timing of the end of the LD season.

“…Chemical application continues to be the cornerstone of I. scapularis and ixodid control worldwide, but can induce ixodid resistance (e.g., Nolan 1990;Beugnet and Chardonnet 1995;Fernandes 2001;Miller et al 2001;Soderlund and Knipple 2003) and negatively affect non-target organisms (Schulze et al 2001b). In field studies, broadcast and barrier synthetic chemical applications using organophosphates, carbamates, or pyrethroids have effectively controlled I. scapularis adults (Schulze et al 1987(Schulze et al , 1992Patrican and Allan 1995), nymphs (Schulze et al 1991(Schulze et al , 1994(Schulze et al , 2000(Schulze et al , 2001aStafford 1991;Solberg et al 1992;Curran et al 1993;Allan and Patrican 1995;Patrican and Allan 1995), and larvae (Schulze et al 1991;Allan and Patrican 1995).…”

Pathogenicity of Metarhizium anisopliae (Deuteromycetes) and permethrin to Ixodes scapularis (Acari: Ixodidae) nymphs

et al. 2005

Effectiveness of the entomopathogenic fungus Metarhizium anisopliae, for controlling nymphal Ixodes scapularis, was tested in laboratory and field trials. In the laboratory, M. anisopliae (Metschnikoff) Sorokin strain ESC1 was moderately pathogenic, with an LC50 of 10(7) spores/ml and induced 70% mortality at 10(9) spores/ml. In a field study, however, 10(9) spores/ml M. anisopliae did not effectively control questing I. scapularis nymphs, and significant differences were not detected in pre- and post-treatment densities. For nymphs collected and returned to the laboratory for observation, mortality was low in treatment groups, ranging from 20 to 36%. To assess whether a chemical acaricide would synergistically enhance pathogenicity of the fungus, we challenged unfed nymphal I. scapularis with combinations of M. anisopliae and permethrin, a relatively safe pyrethroid acaricide, in two separate bioassays. Significant interactions between M. anisopliae and permethrin were not observed, supporting neither synergism nor antagonism.

“…En efecto, Spain (1974) y Schulze et al (2001) encontraron que el carbaril disminuye la densidad de los colémbolos. En coincidencia, los cebos que contienen carbaril como IA, ante las dosis mayores se comportaron de manera similar a la aplicación del insecticida, debido a que ocasionaron mortalidad y disminución del número de crías sobre F. candida (Figura 2).…”

<p>El objetivo del trabajo fue determinar los efectos letales y subletales de metaldehído y/o carbaril sobre Folsomia candida. Se realizaron tres bioensayos bajo un diseño completamente aleatorizado con cuatro repeticiones y en condiciones controladas (20 ± 2 ºC y 14L:10O). La unidad experimental fue un recipiente (9,3 cm de diámetro y 6,4 cm de altura) donde se colocaron 60 g de suelo mezclado con las dosis del cebo y 10 individuos adultos (2 a 3 mm de longitud). Los tratamientos fueron: 0, 40, 80, 120, 160 y 200 g de ingrediente activo (IA) ha-1 de metaldehído; 0, 80, 160, 240, 320 y 400 g IA ha-1 de carbaril; y 0, 40+80, 80+160, 120+240, 160+320 y 200+400 g IA ha-1 de metaldehído+carbaril. Con metaldehído tanto la proporción de individuos vivos como el número de crías no difirieron entre los tratamientos a los 7, 14, 21 y 28 días después de la aplicación (DDA) (p> 0,05). Las dosis mayores de carbaril y metaldehído+carbaril ocasionaron disminuciones en la proporción de individuos vivos y en el número de crías a los 28 DDA (p< 0,05). Los cebos que contienen carbaril causaron mortalidad y disminución en el número de crías de F. candida.</p>
