“…On the other hand, no significant differences between treatments were found in the emergence of false stable fly and dump fly from both treated and control quail droppings, appearing to be an adequate nutrient source for the development of these species. Larvae of these species are facultative predators in late stages of their life, and substrate quality for their development would depend on its protein content (Simon et al, 2011). However, it has been shown that there is no predation if eggs or first instar larvae are put together into the larval medium (Farkas and Jantnyik 1990), as was the case in this study (female had access to lay eggs for a short time window).…”

Many problems in poultry production are caused by a combination of interrelated factors such as management, stress, nutrition, and exposure to pathogens. Saprophagous flies that develop in poultry manure are a potential route of pathogen transmission. Besides being a nuisance, defecation and regurgitation of flies soil equipment and structures and can reduce light levels of lighting fixtures. These effects clearly affect management and may contribute to reductions in poultry egg production, health, and welfare. Many essential oils or their main components have bioactive effects such as natural repellents and insecticides, antioxidants, anticholesterolemics, and antimicrobials. This study evaluated if supplementing quail feed with thymol or isoeugenol as functional food could alter the production of flies from manure. Dropping samples deposited by quail fed with a supplementation of 2,000 mg of thymol or isoeugenol per kg of feed or no supplement (control) were collected. Each sample was incubated inside an emergence cage that was inspected daily to collect emerging adult flies. Fewer flies emerged from droppings of quail fed a thymol-supplemented diet (P = 0.01) and there was a tendency to a lower emergence from droppings of isoeugenol-fed quail (P = 0.09). The number of positive containers for Musca domestica was smaller from quail droppings of thymol- (P = 0.02) or isoeugenol- (P = 0.01) supplemented feed than from the control counterparts, suggesting an oviposition repellent effect. Supplementing quail feed with thymol or isoeugenol has an overall moderate effect against flies, reducing M. domestica emergence.

Performance and body composition of insect larvae depend on quality and quantity of their diet, and on biotic factors such as larval density. We investigated the effect of dietary nutrient concentration and larval rearing density on survival, development, growth, and protein and fat contents of larvae of the black soldier fly (BSF), Hermetia illucens L. (Diptera: Stratiomyidae). Neonate larvae were fed with a low (NC1), intermediate (NC2), or high nutrient concentration (NC3), and with four rearing densities (50, 100, 200, or 400 larvae per container). Two feeding regimes (FR) were tested: in FR1, the amount of diet added during the experiment was based on the visually estimated larval mass present, whereas in FR2, a fixed feeding ration of 0.6 g of food per larva was applied at the start. FR1 resulted in food limitation, resulting in significantly lower body crude protein content on diet NC1 than on NC2 at larval densities 100 and 200. Larval crude fat content was higher on diets with higher nutrient concentration and at lower larval densities. For FR2, development time was shorter on diets with higher nutrient concentration and at lower larval densities. Individual larval weight and total larval yield increased with higher nutrient concentration at all four larval densities. At lower nutrient concentration, higher larval density resulted in higher individual larval weight and total larval yield, revealing an interaction between larval density and dietary quality. Larval crude protein content was higher at lower densities and lower nutrient concentration. Larval crude fat was higher at higher larval densities and nutrient concentrations. This study indicates that larval protein content is regulated within narrow limits, whereas larval crude fat content is strongly affected by nutrient concentration and by larval density.

“…Allometric growth patterns in dipterous larvae have been recorded in few developmental studies by highlighting the measurements of cephalopharyngeal skeleton segments, but they were not extended to forensic application (Lawrence 1979;Petitt 1990). Other than being useful in species identification and distinguishing cryptic species (Canal et al 2015), cephalopharyngeal skeleton of dipterous larvae has been used to describe the growth patterns (Rabbani and Zuha 2017;Simon et al 2011), but the information is still scarce. It is possible, from the present findings, allometric growth of forensically important larvae could be explored further on its patterns and developmental model.…”

Entomological evidence can be utilized in forensic investigation to estimate the elapsed time after death or minimum post mortem interval estimation (PMI min ). This estimation is based on the age of dipterous specimens feeding on decomposing human tissues, which commonly refers to their larval body length. The objective of this research was to look for alternatives to larval body length which could be impaired by specimen handling and subsequently causing inaccuracy in PMI min estimation. In this research, development of forensic blow fly, Hemipyrellia ligurriens (Wiedemann) (Diptera: Calliphoridae), based on larval cephalopharyngeal skeleton length, was described for the first time. Development of H. ligurriens was represented by body length and cephalopharyngeal skeleton consisting anterodorsal process to dorsal cornu (ADP-DC), anterodorsal process to ventral cornu (ADP-VC) and dorsal cornu to ventral cornu (DC-VC). The cephalopharyngeal skeletons proportionally developed with larval body development, but periods of plateau existed between 0 and 10 h and 24-30 h, suggesting ecdysis periods of larvae. Data measurements were more consistent in cephalopharyngeal skeleton length than in larval body length, and there were strong positive significant correlations, r > 0.85 (p < 0.05). These findings warranted further investigations to examine cephalopharyngeal skeleton as an alternative growth parameter to larval body length.
