“…In the present study, we found fecundity was significant differences between seasons; however, fecundity showed no relationship with temperature and just a very weak positive correlation with relative humidity. Similar findings were observed for C. megacephala [ 43 ], and other blow fly species like Chrysomya albiceps [ 44 ] and Lucilia eximia [ 45 ], which fecundity was not significantly affected by changes in temperature. This result suggested that fecundity is probably influenced by the ecological niches occupied by this species, which seasonal and environmental changes may affect the abundance of food resources, e.g.…”

BackgroundChrysomya megacephala is a blow fly species of medical and forensic importance worldwide. Understanding its bionomics is essential for both designing effective fly control programs and its use in forensic investigations.MethodsThe daily flight activity, seasonal abundance related to abiotic factors (temperature, relative humidity and rainfall) and reproductive potential of this species was investigated. Adult flies were sampled twice a month for one year from July 2013 to June 2014 in three different ecotypes (forest area, longan orchard and palm plantation) of Chiang Mai Province, northern Thailand, using semi-automatic funnel traps. One-day tainted beef offal was used as bait.ResultsA total of 88,273 flies were sampled, of which 82,800 flies (93.8%) were caught during the day (from 06:00 to 18:00 h); while 5473 flies (6.2%) were caught at night (from 18:00 to 06:00 h). Concurrently, the abundance of C. megacephala was higher in the forest area (n = 31,873; 36.1%) and palm plantation (n = 31,347; 35.5%), compared to the longan orchard (n = 25,053; 28.4%). The number of females was significantly higher than that of males, exhibiting a female to male sex ratio of 2.36:1. Seasonal fluctuation revealed the highest abundance of C. megacephala in summer, but low numbers in the rainy season and winter. Fly density was significantly positively correlated with temperature, but negatively correlated with relative humidity. No correlation between numbers of C. megacephala with rainfall was found. Activity occurred throughout the daytime with high numbers from 06:00 to 18:00 h in summer and 12:00 to 18:00 h in the rainy season and winter. As for the nocturnal flight activity, a small number of flies were collected in summer and the rainy season, while none were collected in the winter. Dissection of the females indicated that fecundity was highest during the rainy season, followed by winter and summer.ConclusionsSince the assessment of daily, seasonal activity and the reproductive potential of C. megacephala remains a crucial point to be elucidated, this extensive study offers insights into bionomics, which may be considered for integrated fly control strategies and forensic entomology issues.

“…In addition, the results from previous studies designed to investigate the variation of demographic parameters in natural populations of blowflies show a spectrum of parameter values compatible with the numbers used in this study (Reigada & Godoy 2005, Gião & Godoy 2006, Riback & Godoy 2008.…”

“…Unfortunately there is no comparable long-term study focusing on real-world observations of population patterns. However, the spectrum of oscillations in natural populations of exotics is probably wider than native species because of the magnitude of their survival and fecundity in natural conditions (Ullyett 1950, Reigada & Godoy 2005, Gião & Godoy 2006, Riback & Godoy 2008.…”

We combined two models to investigate the theoretical dynamics of five exotic and native blowfly species in response to the Allee effect by using demographic parameters estimated from experimental populations. Most of the results suggest stabilization of dynamic behavior in response to the Allee effect. However, the results depended on the magnitude of the demographic parameters of each species, and also indicated chaotic fluctuations and limit cycles. The results are discussed in the context of larval aggregation, an important biological process for blowflies, which naturally incorporates the Allee effect.

“…Invasive exotic species may contribute to the displacement of native species and even to their extinction, in the event of competition for the same ecological niche. Riback and Godoy (2008) discuss the implications of C. albiceps bionomic variations for that species population dinamics and believe that their results explain at least in part the success of the species following the occurrence of the biological invasion.…”

In this study we describe the diversity of Mesembrinelinae in a biological reserve in the city of Nova Iguaçu, State of Rio de Janeiro. Traps containing sardines were distributed seasonally, at four sites: Site A (22° 58.788' S, 43° 43.459' W), in a forest edge, and sites B (22° 58.523' S, 43° 44.540' W), C (22° 58.350' S, 43° 44.678' W), and D (22° 34.865' S, 43° 27.063' W), located 1,000m, 500m, and 2,000m respectively, inwards from the edge. A total of 2,150 individuals of Mesembrinellinae were collected, representing ten species. Laneela nigripes Guimarães, 1977 was the most abundant species, followed by Mesembrinella bellardiana Aldrich, 1922, Eumesembrinella cyaneicincta (Surcouf, 1919 and Mesembrinella semihyalina Mello, 1967. These species were common and constant during the study period. Mesembrinella batesi Aldrich, 1922, Eumesembrinella quadrilineata (Fabricius, 1805 and Huascaromusca aeneiventris (Wiedmann, 1830) were the less abundant flies, being considered rare and accidental. Eumesembrinella besnoiti (Seguy, 1925) was rare and accessory. Eumesembrinella cyaneicincta, M. bellardiana, M. semihyalina and M. bicolor were mostly collected in site B, while L. nigripes was mostly collected in site C. The edge effect was not evident since the four sites showed similar populations. Site B showed a strong positive relationship between abundance and richness, in site C the correlation was positive and weak, and there was no correlation in A and D. The highest abundance of specimens was recorded during autumn and winter. These flies occurred from the edge up to 2,000m inside the forest.Keywords: blowflies, asynanthropic species, biodiversity, conservation, Atlantic Rain Forest. Mesembrinellinae
