Entomotoxicology involves the analysis of the presence and the effects of toxicological substances in necrophagous insects. Results obtained by entomotoxicological studies may assist in the investigation of both the causes and the time of death of humans and animals. Ethylene glycol (EG) is easy to purchase, sweet and extremely toxic. It may be consumed accidentally or purposefully, in an attempt to cause death for suicidal or homicidal intent. Several cases report fatalities of humans and animals. The present study is the first to examine the effects of EG on the survival, developmental rate and morphology of two blowfly species, (Diptera: Calliphoridae) typically found on corpses and carcasses: Lucilia sericata (Meigen) and L...

Immature Lucilia sericata (Meigen) raised on beef liver, beef heart, pork liver and pork heart at a mean temperature of 20.6°C took a minimum of 20 days to complete development. Minimum development time differences within stages were observed between the meat types (pork/beef), but not the organ types (liver/heart). Daily hyperspectral measurements were conducted and a functional regression was completed to examine the main effects of meat and organ type on daily spectral measurements. The model examined post feeding larval spectral measurements of insects raised on beef liver alone, the effect of those raised on pork compared with those raised on beef, the effect of those raised on heart compared with those raised on liver and the interactional effect of those raised on pork heart compared with those raised on beef liver...

Necrophagous Calliphoridae breed in vertebrate carrion. Their larvae aggregate and form large masses of individuals. These aggregated larvae can reach adulthood faster than scattered larvae, increasing their chances of survival. Furthermore, the gathering of larvae of different species suggests possible interspecific aggregation vectors. In this context, the effect of larval ground-left cues on larvae of Calliphora vomitoria and Lucilia sericata was studied. We used video tracking to follow larvae placed in binary choice tests...

BACKGROUND: Myiasis induced by the sheep blowfly, Lucilia sericata, represents a public health problem widely distributed throughout the world. L. sericata larval stages feed on both humans and animals. L. sericata adults and larvae can play a role in spreading agents of mycobacterial infections. OBJECTIVES: It is critical to establish new and safe alternative methods of controlling L. sericata. METHODS: The insecticidal effectiveness and growth inhibition potential of three commercially available essential oils (EOs), vetiver (Chrysopogon zizanioides), cinnamon (Cinnamomum zeylanicum), and lavender (Lavandula angustifolia), as well as their blends, were tested against the second (L2) and third (L3) larval stages of L...

Wohlfahrtiimonas species bacteria were isolated from the bloodstream of a patient with septicemia and wound myiasis. Environmental investigations identified a Wohlfahrtiimonas sp. among insects in the Americas and in a previously undescribed vector, the green bottle fly (Lucilia sericata). The isolates possibly represent a new species within the genus Wohlfahrtiimonas.

In forensic entomology, many studies analyze fly activity and succession on dead bodies by using pig cadavers and a variety of small baited traps. Data on real human bodies are very rare. To address this shortcoming, we analyzed the fly fauna of 51 human bodies in Germany. Sex, age, place of discovery, and presumed time of death were noted. Larvae were sampled during autopsy according to body region or tissue. For every infested region, the total number of fly larvae were estimated and classified into categories of 1-10, 11-50, and 50+...

Cutaneous ulcers tend to become chronic and have a profound impact on quality of life. These wounds may become infected and lead to greater morbidity and even mortality. In the past, larvae (ie, maggots) of certain common flies (Lucilia sericata and Lucilia cuprina) were considered useful in ulcer management because they only remove necrotic tissue while promoting healthy tissue in the wound bed, thus helping wounds heal faster. Recently, maggots from several other fly species (Calliphora vicina, Calliphora vomitoria, Phormia regina, Chrysomya albiceps, Sarcophaga carnaria, and Hermetia illucens) have been shown in vitro to possess characteristics (ie, debridement efficacy and putative antimicrobial potentialities) that make them suitable candidates for possible use in clinical practice...

OBJECTIVE: Maggot debridement therapy (MDT) has proved an efficient and reliable approach for wound healing. We explain the use of maggots with a stepwise procedure for conducting MDT in a patient with severe and large electrical wounds. METHOD: We captured the flies of Lucilia sericata from the natural environment, Alborz, Iran, and reared them in netted cages. The eggs obtained from the flies were disinfected with chloramine, and then were incubated on culture medium...

Blow flies are important tools in forensic entomology, as they feed and develop on human bodies. This fact can be used to estimate the minimum post mortem interval (PMImin ), by classifying the age of the immature stages found on corpses. The capacity to also be able to classify the age of adult flies, or even empty puparia, could increase the timeframe for a PMImin . However, the association of older developmental stages, such as adult flies or their empty cases, with a human cadaver may be challenged, as such specimens could stem from another food source...

The present study aimed to select an antigen of Lucilia sericata larvae showing both high antigenicity and cross-reactive binding abilities with other related antigens of L. sericata larvae for obtaining a promising candidate vaccine antigen. The ELISA results primary concluded that among the excretory secretory (ES) and midgut (MG) antigens of the different larval instars of L. sericata, MGL2 could be characterized as antigen which was able to reflect the highest level of antigenicity and cross-reactivity with the other tested L...

Blowflies (Diptera: Calliphoridae) are forensically important as they are known to be one of the first to colonise human remains. The larval stage is typically used to assist a forensic entomologists with adult flies rarely used as they are difficult to age because they remain morphologically similar once they have gone through the initial transformation upon hatching. However, being able to age them is of interest and importance within the field. This study examined the cuticular hydrocarbons (CHC) of Diptera: Calliphoridae species Lucilia sericata, Calliphora vicina and Calliphora vomitoria...

Large numbers of flies are needed to produce the quantity of larvae required for insect bioconversion of waste. However, this 'mass-rearing' may negatively affect adult survival and reproductive output. This study assessed the suitability for mass-rearing of four blow fly species, Chrysomya chloropyga, Chrysomya chloropyga (Wiedemann), Chrysomya megacephala (F.), Chrysomya putoria (Wiedemann) and Lucilia sericata (Meigen). Flies were kept at densities of 20, 50, 100, 250, 500, and 1,000 flies per 30 × 30 × 30 cm cage with an even sex ratio...

Leishmaniasis is a vector-borne disease caused by infection by parasites from the genus Leishmania. Clinical manifestations can be visceral or cutaneous, the latter mainly being chronic ulcers. This work was aimed at evaluating Calliphoridae Lucilia sericata- and Sarconesiopsis magellanica-derived larval excretions and secretions' (ES) in vitro anti-leishmanial activity against Leishmania panamensis. Different larval-ES concentrations from both blowfly species were tested against either L. panamensis promastigotes or intracellular amastigotes using U937-macrophages as host cells...

Lucilia sericata maggots have beneficial properties; however, their protective effects on burn wounds have yet to be fully elucidated. In the present study, a deep second‑degree burn rat model was used to investigate the burn wound healing properties of aqueous extract of maggots (MAE). The anti‑inflammatory, antioxidative and antibacterial activities were examined. In addition, the protein expression levels of Akt, vascular endothelial growth factor A (VEGFA) and nuclear factor‑κB (NF‑κB) were detected by western blotting...

Age estimation of insects like blow flies plays an important role in forensic entomology and can answer questions in regard to time of death. So far the focus is on the immature stages of these insects, but recently the adult fly became a target of interest. It has been established that the profile of specific cuticular hydrocarbons (CHCs) changes in a consistent pattern as adult insects age; thus, their analysis could be a promising tool for the age estimation of adult insects. We investigated the CHC n-pentacosane (nC25) on the legs of the adult blow flies Lucilia sericata and Calliphora vicina with gas chromatography-mass spectrometry...

In 2014, highly virulent African swine fever virus (ASFV) was introduced into the Baltic States and Poland, with new cases being reported almost every week from wild boar and also from domestic pigs. Contrary to initial predictions that the disease would either die out due to the high virulence of the virus strain or spread rapidly in westerly direction, the infection became endemic and spread slowly. The unexpected disease epidemiology led to the hypothesis that hitherto unconsidered factors might contribute to virus persistence and dispersal...

Information about blow fly (Diptera: Calliphoridae) species distributions can be valuable for criminal investigations, with regards to determining movement of remains from one location to another and time of colonization estimates, making these data extremely useful. Past work has been conducted on initial species community structure across New Jersey, USA using traps baited with beef liver; however, if these same species frequent vertebrate carrion remains unclear. In order to evaluate these data, piglet carcasses were placed out once every two weeks for a year in New Brunswick, New Jersey, USA...
