“…In demoecological studies, the sex ratio is an essential parameter for characterizing insect populations (Serra et al, 2007;Idder-Ighili et al, 2015). A good indicator of survival, the distribution of age classes, and the dynamics of insect populations (Sadoudi et al, 2011;Kraft and Vannouhuys, 2013), the sex ratio allows estimation and understanding of the effects of environmental conditions or the structure of the habitat during various stages of life history (Suarez-Coya, 2013).…”

This study aims to investigate the diversity, population dynamics, and distribution of forest cockroaches from the litter of three types of Mediterranean forests (Pinus halepensis, Juniperus phoenicea, Quercus ilex) in Belezma National Park (Northeast Algeria). In every type of forest, blattopteran individuals were hand-collected fortnightly from March 2013 to July 2014. Population dynamics were tested by multivariate analysis of variance for forest types and study months. The capture of 1885 individual forest cockroaches allowed the identification of six species (Loboptera angulata, Dziriblatta stenoptera, Phyllodromica subaptera, Phyllodromica zebra, Phyllodromica cincticollis, and Phyllodromica trivittata). In all studied forests, these species produced two generations per year (spring and autumn), in which the number of females was significantly higher than the number of males. However, P. cincticollis established a single generation in the spring with a balanced sex ratio. L. angulata and D. stenoptera were the most abundant species. The values of individual abundances, species richness, and biodiversity were higher in P. halepensis forest compared to Q. ilex and J. phoenicea.

“…There were also significantly more females than males of this species that emerged, but the reason for this difference is unclear. Generally, blowflies usually have a 1:1 sex ratio (31). However, earlier studies (32,33) found that under severe larval competition, a greater number of females emerged as adults.…”

Postfeeding dispersal involves migration of larvae away from their food source in order to pupate. Puparia are difficult to find, yet are important for estimating PMI, and missing puparia during collection can result in inaccurate estimations. This study investigates the late season maggot dispersal patterns for blow flies at coyote carcasses in two habitats with an aim to improving puparia collection procedures. Puparia samples collected from various dispersal distances and directions tested the spatial distribution patterns of the various species using the variance/mean ratio (VMR). Lucilia illustris was the most common species to emerge, with a preferred minimum dispersal distance of more than 50.8 cm and an overall VMR value of 14.91, indicating this species had a clumped distribution pattern. These findings highlight that current collection procedures that use random sampling from under carcasses do not adequately account for the spatial distribution of larvae.

Development time, body mass and length of immatures of Paralucilia fulvinota (Bigot, 1877) (Diptera: Calliphoridae) reared under natural conditions in a Central Amazon forest

Blow flies (Calliphoridae) are used in forensic entomology studies, because their life cycle help to determine the minimum post-mortem interval (PMImin). Paralucilia fulvinota (Bigot, 1877) is a forensic indicator and is reported from human corpses in the Amazonian region. Our objectives were to describe the development time of P. fulvinota under natural conditions at Ducke Reserve (Amazonas), provide the accumulated degree-days (ADD) and accumulated degree-hour (ADH), body length and mass of larvae, and the sex ratio of adults. Pregnant females were sampled on a swine carcass. From hatched eggs, we reared stock colonies and observed the immature development under uncontrolled conditions of temperature (24.5 ± 1.3 ºC), rainfall (188 ± 11.5 mm³) and humidity (84 ± 3.9%). Development time was 11 days. Adult sex ratio was 0.86. Larvae gained mass at constant rates through the instars but grew less in length from the second to the third instar. Accordingly, P. fulvinota grows more in mass than in length when in larval stage. The period from first stadium to adults lasted 159.5 degree-days and 3828 degree-hours. Our results may be helpful in providing a more accurate estimate of PMImin on corpses encountered in forested areas of the Amazon region.
