One of the most common techniques applied for searching living and even dead persons is the FLIR (Forward Looking Infrared) system fixed on an aircraft like e.g. a helicopter, visualizing the thermal patterns emitted from objects in the long-infrared spectrum. However, as body temperature cools down to ambient values within approximately 24h after death, it is common sense that searching for deceased persons can be just applied the first day post-mortem. We postulated that the insect larval masses on a decomposing body generate a heat which can be considerably higher than ambient temperatures for a period of several weeks and that such heat signatures might be used for locating insect infested human remains...

BACKGROUND: Myiasis designates the infestation of live human and vertebrate animals with dipterous (two-winged) larvae (maggots) and is the fourth most common travel-associated skin disease. Furuncle is the most common aspect of cutaneous myiasis. CASE PRESENTATION: A 24-year-old Caucasian female had been back from Cap-Vert. She described pruritus, slight pain, and the sensation of a foreign body moving in the eyelid. Physical examination showed a single furuncle-like nodule with surrounding erythema and a central pore of the upper eyelid through which a serosanguinous fluid was exuding...

Few efforts have been made in Mexico to monitor Rhagoletis pomonella (Walsh) (Diptera: Tephritidae) in commercial hawthorn (Crataegus spp.) crops. Therefore, the main objectives of this study were to evaluate infestation levels of R. pomonella in feral and commercial Mexican hawthorn and to assess the efficacy of different trap-lure combinations to monitor the pest. Wild hawthorn was more infested than commercially grown hawthorn at the sample site. No differences among four commercial baits (Biolure, ammonium carbonate, CeraTrap, and Captor + borax) were detected when used in combination with a yellow sticky gel (SG) adherent trap under field conditions...

The Asian rice gall midge (ARGM) has emerged as a model gall forming pest of rice. The ARGM infestation of rice results in failure of panicle formation and economic loss. Understanding the molecular basis of ARGM-rice interactions is very crucial in order to control this devastating pest of rice. The current investigation was devised to identify bacterial communities present in the ARGM and in addition the bacterial diversity in the maggots during their interaction with susceptible or resistant rice varieties...

With the development of large-scale livestock farming, manure pollution has drawn much attention. Conversion by insects is a rapid and cost-effective new method for manure management. Swine manure conversion with maggots (Musca domestica larvae) has developed, and the harvested maggots are often used as animal feed. However, the flow of heavy metals from manure to downstream processes cannot be ignored, and therefore, heavy metal content was measured in untreated raw manure, maggot-treated manure, harvested maggots and maggot-eating chickens (chest muscle and liver) to evaluate potential heavy metal risks...

OBJECTIVE: Patients with critical limb ischaemia (CLI) lack sufficient blood flow in to the limb, which leads to difficulties in the normal wound healing process. Therefore, maggot debridement therapy (MDT) has not generally been recommended for CLI patients. We evaluated the effectiveness of wound bed preparation by MDT in CLI patients who had undergone mid-foot amputation. METHODS: Patients who underwent mid-foot amputation after angioplasty between April 2014 and October 2016 were retrospectively investigated by classifying them into an MDT group or a conventional treatment group...

We have described a new case of accidental intestinal myiasis that had occurred due to Eristalis tenax in Iran. A 4-year-old girl living in rural area near Bajestan city located in the south of Khorasan Razavi province visited the hospital lab with complaints of one live larva in feces and did not have other symptoms, except anal itching. This case had a history of consuming subterranean village water and did not have a history of traveling outside the city or contact with other patients. Conclusion. Based on the morphology characteristic, the larva was identified as "rat-tailed maggot" or larvae fly E...

This is a case of men with type 2 diabetes mellitus and diabetic foot. The patient was in danger of limb amputation. After improvement of diabetes, hypertension and dyslipidemia therapies a comprehensive treatment of diabetic foot including angioplasty, antibiotics and local maggot therapy was used for diabetic foot management. Therapy result was very satisfying for the patient. Despite of amputation of the 2nd digit due to advanced gangrene, the whole foot function was saved.Key words: diabetes foot - maggot therapies - type 2 diabetes mellitus...

In this study, we first construct an age-stage, two-sex life table for onion maggot, Delia antiqua, grown on three host plants: onion, scallion, and garlic. We found that onion is the optimal host for this species and populations grown on onion have maximum fecundity, longest adult longevity and reproduction period, and the shortest immature developmental time. In contrast, the fecundity on other hosts was lower, particularly on garlic, but these crops can also serve as important secondary hosts for this pest...

The activities of biological molecules usually rely on both of intra-molecular and intermolecular interactions between their function groups. These interactions include interonic attraction theory, Van der Waal's forces and the function of geometry on the individual molecules, whether they are naturally or synthetic. The purpose of this study was to evaluate the antibacterial activity of C-F bond compound using combination of experiments verification and theoretical calculation. We target on the insect natural products from the maggots of Chrysomyis megacephala Fabricius...

The past 25 years have seen an increase in use of maggot therapy for wound care. Maggot therapy is very effective in wound debridement; it is simple to apply and requires very little in the way of resources, costs, or skilled personnel. These characteristics make it well suited for use in austere environments. The use of medical-grade maggots makes maggot therapy nearly risk free, but medical grade maggots may not always be available, especially in the wilderness or in resource-limited communities. By understanding myiasis and fly biology, it should be possible even for the nonentomologist to obtain maggots from the wild and apply them therapeutically, with minimal risks...

Maggot debridement therapy (MDT) is an effective method for debriding wounds such as leg ulcers, supporting the concept of wound bed preparation ( Dumville et al, 2009 ; Soares et al, 2009 ; Mudge et al, 2014 ). New evidence is emerging to suggest that maggots might contribute to wound healing in other ways. For example, the reduction of biofilms and disinfection of wounds ( Van Der Plas et al, 2008 ; Brown et al, 2012 ; Pritchard and Brown, 2015 ) plus regulation of protease levels ( Chambers et al, 2003 ; Van Der Plas et al, 2009a ; Van Der Plas et al, 2009b )...

Ischaemic skin ulcer occurred on the foot of a 73-year-old man who had a history of fulminant myocarditis with severe cardiac dysfunction. We attempted wound bed preparation by maggot debridement therapy and salvaged his limb. It can be one of the adjuvant treatment strategies for critical limb ischaemia.

Larval Drosophila offer a study case for behavioral neurogenetics that is simple enough to be experimentally tractable, yet complex enough to be worth the effort. We provide a detailed, hands-on manual for Pavlovian odor-reward learning in these animals. Given the versatility of Drosophila for genetic analyses, combined with the evolutionarily shared genetic heritage with humans, the paradigm has utility not only in behavioral neurogenetics and experimental psychology, but for translational biomedicine as well...

Male-biased aggregations of sugar beet root maggot, Tetanops myopaeformis (Röder) (Diptera: Ulidiidae), flies were observed on utility poles near sugar beet (Beta vulgaris L. [Chenopodiaceae]) fields in southern Idaho; this contrasts with the approximately equal sex ratio typically observed within fields. Peak observation of mating pairs coincided with peak diurnal abundance of flies. Volatiles released by individual male and female flies were sampled from 08:00 to 24:00 hours in the laboratory using solid-phase microextraction and analyzed using gas chromatography/mass spectrometry (GC/MS)...

Maggot debridement therapy (MDT) refers to the use of blowfly larvae to clean or debride an infected wound. Most commonly, larvae of Lucilia sericata (Meigen) (Diptera: Calliphoridae) are used, and are sterilized prior to use to ensure no further bacterial infections are introduced during treatment. Current methods sterilize eggs from laboratory-reared blowfly colonies, after which sterile early second instar maggots can be provided to hospitals for use in treatment. Maggots not required for treatment are used for colony regeneration, in which sterility is not maintained...

We present a case of severe orbital myiasis caused by Osteris ovis, also known as sheep nasal botfly which is an uncommon manifestation of maggot infestation. Our patient was successfully treated with oral as well as topical ivermectin. The experience of ivermectin as an anti-parasitic agent in the treatment of orbital myiasis, although a known entity, is still limited among medical professionals including ophthalmologists. Thus, we would like to highlight the role of oral ivermectin as an anti-parasitic agent in the treatment of orbital myiasis facilitating the removal of maggots; thus, precluding the need for exploratory surgery...

The thermoregulation behavior of Lucilia sericata larvae (Diptera: Calliphoridae), a necrophagous species that feeds on vertebrate cadavers, was investigated. These larvae require high heat incomes to develop, and can elevate temperatures by forming large aggregates. We hypothesized that L. sericata larvae should continue to feed at temperatures up to 38°C, which can be reached inside larval masses. Thermal regulation behavior such as movement between a hot food spot and colder areas was also postulated. The hypotheses were tested by tracking for 1h the activity of single, starved third instar larvae in a Petri dish containing one food spot (FS) that was heated to a constant temperature of 25°C, 34°C or 38°C with an ambient temperature of 25°C...

Maggot debridement therapy (MDT) is an application of sterile laboratory-reared blow fly larvae to remove necrotic tissue and disinfect wounds for medical conditions. For effective application, the blow fly larvae used in the wound treatment are required to be in aseptic condition. Here, we report the results of a detailed assessment of bacteria and fungi isolated from the eggs of two blow fly species, Chrysomya megacephala (F.) and Lucilia cuprina (Wiedemann) before and after sterilization by disinfectants Chlorhex-C, povidone-iodine, and sodium hypochlorite...
