“…The Siphonaptera are small, wingless, holometabolous insects that parasitize endothermic animals, especially mammals (LINARDI, 2011). Ctenocephalides felis felis Bouché, 1835 (Pulicidae) is permanent parasite and the primary flea infesting cats and dogs in most of the world (DRYDEN & RUST, 1994).…”

The Siphonaptera are parasitic insects of endothermic animals and Ctenocephalides felis and Pulex irritans are important parasites of dogs. This study evaluated the effect of hair coat length and time of year on the population size of C. felis and P. irritans in naturally infested dogs. Fleas were collected from 14 dogs on a monthly basis for a year (February 2015 to January 2016) at a rural property in Bagé, Rio Grande do Sul, Brazil. The dogs were divided into two groups based on hair coat length: short coat (coat length < 5.0 cm, n= 7) and long coat (coat length > 5.0 cm, n= 7). In total, 2057 fleas were collected, 1541 of which were C. felis (74.91%) and 516 were P. irritans (25.08%). The number of C. felis and P. irritans individuals was significantly affected by hair coat length and time of year. The variation in flea numbers over the study months was higher in long-coated than in short-coated dogs for the two flea species and flea numbers increased with increasing mean monthly temperatures. The results provide a better understanding of behavioral aspects of flea communities in dogs and may help develop control strategies targeting these parasites.Keywords: Ctenocephalides felis, Pulex irritans, flea, dog, behavior. ResumoSifonápteros são insetos parasitos de animais endotérmicos e Ctenocephalides felis e Pulex irritans são importantes parasitos dos cães. O objetivo deste trabalho foi avaliar a influência da altura da pelagem de cães sobre as espécies de pulgas em diferentes meses do ano. Foram coletadas mensalmente, durante um ano, 10 a 15 pulgas em 14 cães de uma propriedade rural no município de Bagé, RS, Brasil. Os cães foram divididos em dois grupos: "pelo curto" e "pelo longo", com 07 cães em cada grupo, com altura da pelagem inferior e superior a 5 cm, respectivamente. Coletou-se 2.057 pulgas, 1.541 (74,91%) C. felis e 516 (25,08%) P. irritans. O número de indivíduos de C. felis e de P. irritans foi influenciado significativamente, pelo comprimento do pelo dos animais e pelos diferentes meses do ano. Houve maior variação do número de indivíduos das duas espécies, durante os meses, em cães de pelos longos e a curva de aumento populacional acompanhou o aumento das temperaturas médias mensais. Os resultados são importantes para o melhor conhecimento de aspectos comportamentais de comunidades de pulgas em cães e para o planejamento de estratégias de controle desses parasitos.

“…The higher incidence of P. irritans during colder times of the year (Figures 1-3) is noteworthy, as this species has a Neotropic origin (LEWIS, 1972). The Pulicidae may be changing its habits of seeking the host only for feeding (LINARDI, 2011), as the canine host also provides protection against abiotic conditions. In another study (SILVA et al, 2016), our research group, has shown the preference of P. irritans for long-haired dogs, confirming a trend for this flea to remain in the dogs, thus changing their eating behavior.…”

“…Ctenocephalides felis Bouché 1835 is the most frequent species found in dogs and cats in Europe and in America (CASTRO;RAFAEL, 2006;STALLIVIERI et al, 2009), while Ctenocephalides canis Curtis 1826 seems to have a more restricted geographical distribution (MARCHIONDO et al, 2007), better adapting to low temperature regions (GUIMARÃES et al, 2011;OLIVEIRA;RIBEIRO, 1983). Pulex irritans Linnaeus 1758 is a cosmopolitan Pulicidae of eclectic food preferences whose adults usually do not reside on the body of the host only seeking the host for biting (LINARDI, 2011). There are reports from several countries showing that this flea parasitizes different species of domestic animals such as dogs and cats (DOBLER; PFEFFER; 2011), sheep, goats, cattle and pigs (DOMÍNGUEZ-PEÑAFIEL et al, 2011;KAAL et al, 2006;RAHBARI et al, 2008).…”

EFFECT OF EL NIÑO PHENOMENON ON THE SEASONALITY OF Pulicidae (Siphonaptera) IN DOGS IN A RURAL AREA OF SOUTHERN BRAZIL

The aim of this study was to investigate the effect of El Niño phenomenon on the seasonality of flea species present on dogs from a rural area in Southern Brazil, and on the relationship between the frequency of these species and the climatic conditions in that micro-region. Over three years (2013-2016) 8,974 fleas were collected from 20 dogs. Ctenocephalides felis was the most frequent species (70.14%), followed by Pulex irritans (28.82%) and Ctenocephalides canis (1.05%). The number of C. felis and C. canis individuals varied significantly with the year and with the season of the year, whereas the number of P. irritans was only influenced by the season. C. felis was more prevalent than all the other species in all seasons studied. There was a significant difference in the number of specimens collected during 2015, under the influence of El Niño, compared to 2013 but not to 2014. There was a higher incidence of P. irritans during the cooler periods. C. canis population increased during colder seasons whereas no individuals were collected in years with lower average temperatures. The present study expanded the current knowledge about the seasonal variations in the Siphonapteran populations parasiting dogs, especially in the years under influence of El Niño.

“…The number of flea species in the Neotropics ( n = 289) is similar to those in the Nearctic and Afrotropics ( n = 299 and n = 275, respectively), but much smaller than that in the Palaearctic ( n = 892) (Medvedev & Krasnov, 2006). In Brazil, only 62 species and subspecies of fleas have been recorded (Linardi, 2011), although Brazil is considered to represent a hotspot of global biodiversity (Mittermeier et al , 1998; Myers et al , 2000) and occupies a vast area. Furthermore, flea fauna in Brazil and, in general, in the entire Neotropics is composed mainly of species that: (a) belong to species‐poor genera, and (b) have narrow geographic ranges (Medvedev, 2005).…”

The effects of host-related, parasite-related and environmental factors on the diversity and abundance of two ectoparasite taxa, fleas (Insecta: Siphonaptera) and mites (Acari: Mesostigmata), parasitic on small mammals (rodents and marsupials), were studied in different localities across Brazil. A stronger effect of host-related factors on flea than on mite assemblages, and a stronger effect of environmental factors on mite than on flea assemblages were predicted. In addition, the effects of parasite-related factors on flea and mite diversity and abundance were predicted to manifest mainly at the scale of infracommunities, whereas the effects of host-related and environmental factors were predicted to manifest mainly at the scale of component and compound communities. This study found that, in general, diversity and abundance of flea and mite assemblages at two lower hierarchical levels (infracommunities and component communities) were affected by host-related, parasite-related and environmental factors, and compound communities were affected mainly by host-related and environmental factors. The effects of factors differed between fleas and mites: in fleas, community structure and abundance depended on host diversity to a greater extent than in mites. In addition, the effects of factors differed among parasite assemblages harboured by different host species.
