Effects of pyriproxifen on wild populations of the house fly, Musca domestica, and compatibility with its principal parasitoids.

The house fly, Musca domestica L., is an important pest of animal agriculture. Effective fly management requires integration of manure management, mass trapping, biological control, and selective insecticide use. Insecticidal control of house flies is difficult due to the rapidity of resistance development, yet the insect growth regulator pyriproxyfen (PPF) is one of few insecticides that may still be effective. Here, we tested the susceptibility of four wild house fly populations in the USA and in Israel t...

The objective of this study was to determine the effect of house cricket (Acheta domesticus) flour addition on physicochemical and textural properties of meat emulsion under various formulations. As an initial marker of functionality, protein solubility, water absorption, emulsifying capacity, and gel formation ability of house cricket flour were determined at pH (2 to 10) and NaCl concentrations (0 to 2.10 M). Control emulsion was formulated with 60% lean pork, 20% back fat, and 20% ice. Six treatment emul...


Toxicity and Sublethal Effects of Cantharidin on Musca domestica (Diptera: Muscidae).

The house fly, Musca domestica L. (Diptera: Muscidae), is a major pest of medical and veterinary importance all over the world. Management efforts for house flies are usually compromised owing to their resistance to many groups of conventional insecticides. Cantharidin, a natural toxin produced by meloid beetles, is a biopesticide with a reported toxicity to some insect pests including house flies. However, the effects of cantharidin on biological and fitness parameters of house flies have not yet been inve...

Hen's egg allergen in house and bed dust is significantly increased after hen's egg consumption - a pilot study.

Environmental exposure to food allergens may be a risk factor for cutaneous sensitization. Previous studies could detect peanut allergen in house dust. In this pilot study, we wanted to investigate whether hen's egg allergen is detectable in house dust collected from different household areas and whether levels are increased after intentional hen's egg consumption. Hen's egg protein levels of dust samples were measured using ELISA. In 8/8 households, hen's egg was detectable in dust samples of eating area a...

Molecular analyses of the agouti allele in the Japanese house mice identify a novel variant of the agouti gene.

It has been thought that Japanese house mice carry the Aw allele at the agouti locus causing light-colored bellies, but they do not always show this coloration. Thus, the presence of the Aw allele seems to be doubtful in them. To ascertain whether the Aw allele is present, a two-pronged approach was used. First, we compared lengths of DNA fragments obtained from three PCRs conducted on them to the known fragment sizes generated from mouse strains exhibiting homozygosities of either a/a, A/A, or Aw/Aw. PCRs ...

Computer-Aided Surgical Simulation in Head and Neck Reconstruction: A Cost Comparison among Traditional, In-House, and Commercial Options.

 Computer-aided surgical simulation (CASS) has redefined surgery, improved precision and reduced the reliance on intraoperative trial-and-error manipulations. CASS is provided by third-party services; however, it may be cost-effective for some hospitals to develop in-house programs. This study provides the first cost analysis comparison among traditional (no CASS), commercial CASS, and in-house CASS for head and neck reconstruction.

A Microsatellite-Based Analysis of House Infestation With Triatoma Infestans (Hemiptera: Reduviidae) After Insecticide Spraying in the Argentine Chaco.

Prevention of vector-borne transmission of Chagas disease mainly relies on residual insecticide spraying. Despite significant success at a regional scale, house infestation with Triatoma infestans (Klug) (Hemiptera: Reduviidae) still persists in the Gran Chaco ecoregion. One key aspect is the identification of the sources of reinfestant triatomines. After detecting fine-scale genetic structure in two rural villages of Pampa del Indio, Argentine Chaco, we tested hypotheses on the putative origins of the tria...

Dose-Dependent Effects on Replication and Persistence of Salmonella enterica serovar Typhimurium in House Flies (Diptera: Muscidae).

Adult house flies (Musca domestica L.) ingest variable numbers of bacteria when they encounter microbe-rich substrates. Bacterial abundance may affect replication within the fly gut, which subsequently impacts vector potential. This study investigated the dose-dependent replication of GFP-expressing Salmonella enterica serovar Typhimurium (ex Kauffmann and Edwards1952) Le Minor and Popoff 1987, (Enterobacteriales: Enterobacteriaceae) (GFP S. Typhimurium) within the fly alimentary canal. Adult house flies we...

Effects of house prices on health: New evidence from Australia.

Recent house price variation has strongly affected households' housing wealth and debt, yet the non-economic consequences of these changes in housing wealth are still poorly understood. Using a sample of 19,000 individuals from the Household, Income and Labour Dynamics in Australia Survey (HILDA) for 2001-2015, we examine the relationship between house price fluctuations and individual health by exploiting large exogenous changes in house prices in Australia. We find that an increase in local house prices i...

Using an In-House Approach to Computer-Assisted Design and Computer-Aided Manufacturing Reconstruction of the Maxilla.

Computer-assisted design (CAD) and computer-aided manufacturing (CAM) techniques are in widespread use for maxillofacial reconstruction. However, CAD/CAM surgical guides are commercially available only in limited areas. To use this technology in areas where these commercial guides are not available, the authors developed a CAD/CAM technique in which all processes are performed by the surgeon (in-house approach). The authors describe their experience and the characteristics of their in-house CAD/CAM reconstr...

Assessment of DDT contamination in house rat as a possible bioindicator in DDT-sprayed areas from Ethiopia and South Africa.

Ethiopia and South Africa are among the few countries to still implement indoor residual spraying with dichloro-diphenyl-trichloroethane (DDT) for malaria vector control. In this study, we investigated the levels and ecological risks of DDT and its metabolites in liver tissues of house rat, as a sentinel animal, for providing an early warning system for public health and wildlife intervention from Ethiopia and South Africa. The results showed that ΣDDT concentration ranged from 127 to 9155 μg/kg wet weig...

Response of House Finches Recovered from Mycoplasma gallisepticum to Reinfection with a Heterologous Strain.

After recovery, house finches ( Haemorhous mexicanus) reinfected with the same Mycoplasma gallisepticum strain remain partially resistant to reinfection for at least 14 mo in that they recover from reinfection much more rapidly than do Mycoplasma gallisepticum-naïve birds. To test the response of birds to reinfection with a heterologous strain we performed two experiments. In a first experiment we exposed birds to one of three strains that differed in virulence. After they had recovered all were reinfected...

A simple mathematical method to estimate ammonia emission from in-house windrowing of poultry litter.

In-house windrowing between flocks is an emerging sanitary management practice to partially disinfect the built-up litter in broiler houses. However, this practice may also increase ammonia (NH3) emission from the litter due to the increase in litter temperature. The objectives of this study were to develop mathematical models to estimate NH3 emission rates from broiler houses practicing in-house windrowing between flocks. Equations to estimate mass-transfer areas form different shapes windrowed litter (tri...

Similar localization of conformational IgE epitopes on the house dust mite allergens Der p 5 and Der p 21 despite limited IgE-cross-reactivity.

Due to high IgE recognition frequency and high allergenic activity, Der p 5 and Der p 21 are clinically important house dust mite (HDM) allergens. The objective of this study was to characterise the immunodominant IgE epitopes of Der p 5 and Der p 21 responsible for their high allergenic activity.

I thought he was going to set our house on fire.

Recently the wife of an octogenarian suffering from dementia brought her husband to the emergency department stating, "I can't take care of him anymore. He is becoming more aggressive. I thought he was going to set our house on fire last night". She recounted finding her husband in the kitchen at the range turning the dials. This article is protected by copyright.

Here, Paul Browning, (Doctoral Research Student, University of Worcester, employed by 3M UK plc) summarises the key points from the evening and explains why it is so important we keep wound care on the Government's agenda.

Prevalence of Shiga-toxigenic Escherichia coli in House Flies (Diptera: Muscidae) in an Urban Environment.

House flies (Musca domestica L. [Diptera: Muscidae]) can act as a mechanical vector for food-borne pathogens including Shiga toxin-producing Escherichia coli (Migula; Enterobacteriales: Enterobacteriaceae) (STEC) in and around cattle feedlots. The present study assessed the prevalence of STEC in house flies from a restaurant area of a town in northeastern Kansas.

Effects of urbanization on host-pathogen interactions, using Yersinia in house sparrows as a model.

Urbanization strongly affects biodiversity, altering natural communities and often leading to a reduced species richness. Yet, despite its increasingly recognized importance, how urbanization impacts on the health of individual animals, wildlife populations and on disease ecology remains poorly understood. To test whether, and how, urbanization-driven ecosystem alterations influence pathogen dynamics and avian health, we use house sparrows (Passer domesticus) and Yersinia spp. (pathogenic for passerines) as...

Longevity of Fly Baits Exposed to Field Conditions.

Insecticidal fly baits are important tools for adult house fly, Musca domestica L. (Diptera: Muscidae), control, especially on animal operations. Two house fly baits, containing either cyantraniliprole or dinotefuran, were tested on a dairy farm for attractiveness over time compared to a sugar control. Sticky trap and bucket trap house fly catches were recorded for each bait type at 1 h, 3 h, 6 h, 12 h, 24 h, 48 h, 72 h, and 168 h. After 1 wk of exposure to flies and field conditions, these 'aged' baits wer...

Associations between flame retardant applications in furniture foam, house dust levels, and residents' serum levels.

Polyurethane foam (PUF) in upholstered furniture frequently is treated with flame retardant chemicals (FRs) to reduce its flammability and adhere to rigorous flammability standards. For decades, a commercial mixture of polybrominated diphenyl ethers (PBDEs) called PentaBDE was commonly applied to foam to fulfill these regulations; however, concerns over toxicity, bioaccumulation, and persistence led to a global phase-out in the mid-2000s. Although PentaBDE is still detected in older furniture, other FR comp...
