Registro de Aphaereta laeviuscula (Spinola) (Hymenoptera: Braconidae) e Nasonia vitripennis (Walker) (Hymenoptera: Pteromalidae) como parasitóide de Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae), no estado do Rio de Janeiro

Abstract

Lab. Ixodides -Fundação Oswaldo Cruz (FIOCRUZ) -Av. Brasil 4365, 21045-900, Manguinhos, RJ Neotropical Entomology 35(3): 402-407 (2006) Register of Aphaereta laeviuscula (Spinola) (Hymenoptera: Braconidae) and Nasonia vitripennis (Walker) (Hymenoptera: Pteromalidae) as Parasitoids of Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae), in the State of Rio de Janeiro, Brazil ABSTRACT -The captures occurred between January and December of 2004 in urban area in the city of Nova Iguaçu, the rural area of the city of Seropédica and in a forest area in the Biological Reserve of the Tinguá, Nova Iguaçu State of Rio de Janeiro. The total of 1,528 larvae of Cochliomyia hominivorax (Coquerel) were used as bait, 505 in the urban area, 556 in rural and the 467 in the forest one. The indices of Synantropic, Coefficient of Constancy, the risk (Odds Ratio) of parasitism between the areas was calculated, prevalence and parasitic intensity. The percentage of emergence was of 46.6%. Aphaereta laeviuscula (Spinola) was captured only in rural environment; its indices were: Synantropic I. = +50, c. constancy = 25%, prevalence = 0.72% and I. parasitic = 44.5; already Nasonia vitripennis (Walker) was captured in the areas rural and urban and the indices had been: synanthropy = +98, constancy = 58.3%, Odds Ratio = IC95% = 0,025 < μ > 0.27, P < 0,05, prevalence = 3.2% and parasitic intensity = 7.35. A espécie A. laeviuscula foi capturada apenas em ambiente rural, seus índices foram: sinantropia = +50, c. constância = 25%, prevalência = 0,72% e intensidade parasitária = 44,5. N. vitripennis foi capturada nas áreas rural e urbana e os índices foram: sinantropia = +98, constância = 58,3%, Odds Ratio = IC95% = 0,025 < μ > 0,27, P < 0,05, prevalência = 3,2% e intensidade parasitária = 7,35. O risco de parasitismo por N. vitripennis em áreas urbanas é alto.

Occurrence and seasonality of muscoids dipterous (Diptera, Calliphoridae) at Colégio Pedro II campus Niterói, Barreto, Niterói, RJ, Brazil

“…Therefore, the synanthropic index for C. albiceps varied between +4.8 (Flamengo borough) and +6.3 (at the bus terminal), showing complete independence from inhabited areas. The synanthropic index of the collections made solely at UERJ campus showed the preference for inhabited areas (+36.9), which coincided with the studies by Rodrigues- Guimarães et al (2008). Back in the days when Seropédica was considered a rural area, Carraro & Milward-de-Azevedo (1999) found a large population of C. albiceps.…”

“…Chrysomya putoria was the second most abundant species collected at Colégio Pedro II campus Niterói, which differs from Sordillo (1991), Rodrigues-Guimarães et al (2008) and Batista-da-Silva et al…”

“…According to Lima;Luz (1991), the species of Chrysomya were well adapted to the tropical regions where the environment was modified by men, and through the process of adaptation, these species of Chrysomya altered the fauna of the areas mentioned above. (Carraro & Milward-deAzevedo, 1999); northern region of Rio de Janeiro city (Lopes, 2000); Paracambi (Mello et al, 2004); Baixada Fluminense (Rodrigues- Guimarães et al, 2008); Itaboraí (Batista-da-Silva et al, 2010) and Vassouras (Macedo et al, 2011). Chrysomya megacephala is the most synanthropic species found in most Brazilian cities where captures were made.…”

“…In March 2015, only one female of Chloroprocta idioidea was collected. Rodrigues- Guimarães et al (2008) collected C. idioidea in the forest area of the Baixada Fluminense region. In the population studies of Calliphoridae, carried out by Batista-da-Silva et al (2010) in Itaboraí, it was also found that this species is typically forest-based.…”

Edge effects on the blowfly fauna (Diptera, Calliphoridae) of the Tijuca National Park, Rio de Janeiro, Brazil

“…Its distribution is strongly influenced by temperature (r=0.7634, p=0.0038), as it occurs in greater abundance in the warmer months, as observed by D' Almeida and Fraga (2007). It was also the most abundant species in studies conducted by Paraluppi and Castellón (1994) in a region of the Amazon rainforest; by Rodrigues-Guimarães et al (2004) in the metropolitan area of Rio de Janeiro; and by Mello et al (2004) and Dias et al (2009) next to garbage dumps in Rio de Janeiro and São Paulo, respectively. Such high incidence of this species in different areas was explained by Prado and Guimarães (1982), who considered it as r-strategist with generalist feeding habits, a combination that results in high adaptability to diverse environments such as forest fragments.…”
