The present paper reports a case of human vaginal myiasis in a 22 year old woman. This is the first report of this fly species to cause vaginal myiasis in human till now. The infested maggots were removed from the vagina and cultured in laboratory. Entomological studies on the emerged flies showed that the infested larvae were Oriental latrine fly Chrysomya megacephala Fabricius. Clinical presentation and treatment strategies are discussed also.

Maggots, through their excretions and secretions (ES), promote wound healing by removing necrotic tissue, counter bacterial infection, and activate wound associated cells. We investigated the effects of a physiological dose of maggot ES on four wound-associated cell types in vitro with Affymetrix gene expression arrays; keratinocytes, endothelial cells, fibroblasts and monocytes. Keratinocytes showed the fewest (n=5; p<0.05, fold-change ±2) and smallest fold-changes (up to 2.32x) in gene expression and conversely THP1 monocytes had the most (n=233) and greatest magnitude (up to 44...

Rabbit carcass decomposition was examined in four seasons in Al-Ahsaa Oasis. Decomposition rate was significantly faster in summer compared with other seasons. Fourteen insect species from four orders and seven families were recorded: Calliphoridae, Muscidae, Sarcophagidae, Formicidae, Histeridae, Dermestidae, and Tenebrionidae. Most of the fly maggots collected were Calliphoridae with only one species from both Muscidae and Sarcophagidae. Maggots of Calliphora vicina (R.-D.) and Chrysomya albiceps (Wiedemann) colonized the carcasses in all seasons while both Ch...

Myiasis is a relatively common infection of animals kept as pets, although only 1 case of canine myiasis has been described so far in the Republic of Korea. In the present study, we report an additional case of canine wound myiasis with identification of its causative agent, Lucilia sericata. An 8-year-old male Siberian husky dog was referred with anorexia, vomiting, and diarrhea to the Chungbuk National University Veterinary Medical Center, Cheongju-si (city), Chungcheongbuk-do (province), Korea in July 2013...

Although the life cycle of the equid stomach parasite Habronema muscae was disclosed more than 100 years ago, little is known about the effect of the developing nematode larvae in its intermediate host, Musca domestica. In a series of experiments, freshly hatched M. domestica larvae were exposed to H. muscae eggs contained in a faecal sample of a naturally infected horse. In daily intervals, 50 fly larvae were removed and transferred on a parasite-free larval rearing medium where they completed their development...

Sheep flystrike is caused by parasitic flies laying eggs on soiled wool or open wounds, after which the hatched maggots feed on the sheep flesh and often cause large lesions. It is a significant economic problem for the livestock industry as infestations are difficult to control due to ongoing cycles of larval development into flies followed by further egg laying. We therefore screened venom fractions from the Australian theraphosid spider Coremiocnemis tropix to identify toxins active against the sheep blowfly Lucilia cuprina, which is the primary cause of flystrike in Australia...

Maggot debridement therapy (MDT) is the use of medical grade maggots of the fly Lucilia sericata for wound debridement. Recent observations show that MDT decreases bacterial burden as well. Venous ulcers are the most commonly seen in wound clinics and require, besides adequate treatment of venous hypertension, proper wound bed preparation with debri dement of necrotic tissue and control of potential infections. To evaluate the efficacy of MDT in venous ulcers a randomized controlled trial was designed to compare MDT to surgical debridement and topical application of silver sulfadiazine (SSD) in 19 patients for 4 weeks...

Many vegetable insect pests are managed using neonicotinoid and pyrethroid insecticides. Unfortunately, these insecticides are toxic to many bees and natural enemies and no longer control some pests that have developed resistance. Anthranilic diamide insecticides provide systemic control of many herbivorous arthropod pests, but exhibit low toxicity to beneficial arthropods and mammals, and may be a promising alternative to neonicotinoids and pyrethroids. Anthranilic diamides may be delivered to vegetable crops via seed, in-furrow, or foliar treatments; therefore, it would be desirable to identify which application method provides high levels of pest control while minimizing the amount of active ingredient...

Sugar beet root maggot (SBRM, Tetanops myopaeformis von Röder) is a major but poorly understood insect pest of sugar beet (Beta vulgaris L.). The molecular mechanisms underlying plant defense responses are well documented, however, little information is available about complementary mechanisms for insect adaptive responses to overcome host resistance. To date, no studies have been published on SBRM gene expression profiling. Suppressive subtractive hybridization (SSH) generated more than 300 SBRM ESTs differentially expressed in the interaction of the pest with a moderately resistant (F1016) and a susceptible (F1010) sugar beet line...

Maggot debridement therapy (MDT) consists on the intentional and controlled application of sterilized larvae of the order Diptera on necrotic skin lesions with the purpose of cleaning necrotic tissue and removing pathogenic bacteria. During MDT, a marked antimicrobial activity has been reported in literature specially associated with antibacterial substances from Lucilia sericata (Meigen); however, regarding Cochliomyia macellaria (Fabricius), little is known. This study aimed to evaluate in vitro inhibition of bacterial growth of Pseudomonas aeruginosa and Staphylococcus aureus in contact with excretions and secretions (ES) from C...

Ethyl glucuronide (EtG) and ethyl sulfate (EtS) are specific and sensitive biomarkers for the diagnosis of acute or chronic alcohol abuse. Due to postmortem alcohol production in biological tissues, they have recently been evaluated as potential biomarkers of ethanol ingestion. This in vitro study aimed to evaluate all developmental stages of the fly Calliphora vicina L. (Calliphoridae). Different pig substrates were used during the in vitro experiments to rear C. vicina Experiments were performed to: (i) assess the presence of EtG and EtS in larvae, pupae and insects; (ii) study variability due to the substrates characteristics; (iii) evaluate the possibility of false positives due to external alcohol contamination; and (iv) estimate the potential metabolism of ethanol by the insects...

Oviposition attractants for the house fly Musca domestica have been investigated using electrophysiological tests, behavioural assays and field tests. Volatiles were collected via head space absorption method from fermented wheat bran, fresh wheat bran, rearing substrate residue and house fly maggots. A Y-tube olfactometer assay showed that the odor of fermented wheat bran was a significant attractant for female house flies. Bioactive compounds from fermented wheat bran for house fly females were identified by electrophysiology and mass spectrophotometry and confirmed with standard chemicals...

Species that compete for access to or use of sites, such as parasitic mites attaching to honey bees or apple maggots laying eggs in fruits, can potentially increase their fitness by carefully selecting sites at which they face little or no competition. Here, we systematically investigate the evolution of site-selection strategies among animals competing for discrete sites. By developing and analyzing a mechanistic and population-dynamical model of site selection in which searching individuals encounter sites sequentially and can choose to accept or continue to search based on how many conspecifics are already there, we give a complete characterization of the different site-selection strategies that can evolve...

Blowfly larvae aggregate on exposed carcasses and corpses and pass through three instars before wandering from the carcass and pupating. The developmental landmarks in this process can be used by forensic entomologists to estimate the time since the insects colonised the carcass, which sets a minimum post mortem interval. Large aggregations of feeding larvae generate a microclimate with temperatures up to 15°C above ambient conditions, which may accelerate larval development and affect forensic estimates of post-mortem intervals...

Climate change has brought about an increasing level of seedcorn maggot (Delia platura Meigen, 1826) (Diptera: Anthomyiidae) damage in Hungary. In order to have a more accurate understanding of the effects of these plant injuries induced by the larvae of D. platura, the nutrient content of soybean (Glycine max L. Merill.) was studied. Our results show that the moisture, raw fat, raw fibre, and raw ash content of the batches damaged by D. platura were significantly less in comparison with that of the control samples...

The onion maggot, Delia antiqua, is a devastating pest of liliaceous crops and current control measures fail to avert pesticide residues, threats to agroecosystem, and costly expenditures. Insect growth regulators (IGRs) are used as trypetid pest chemosterilants for their suppression on adult fertility and fecundity, but their effects on onion flies are unknown. Here, three IGRs (lufenuron, cyromazine, pyriproxyfen) were incorporated into baits to evaluate their effects on onion fly survival, fecundity, fertility, susceptibility of adults in different ages and offspring development...

Use of sterile fly larvae (maggots) of blow flies for the treatment of many different types of skin and soft tissue wounds is called Maggot debridement therapy (MDT). The larvae of blow flies secrete a broad spectrum of compounds with diverse mechanisms of action in the gut and salivary glands called excretion/secretion (ES) products which showed to have antimicrobial activities against Gram negative and positive bacteria. Cutaneous leishmaniasis (CL) which is the common form of leishmaniasis is difficult to treat...
