The synanthropic house fly, Musca domestica (Diptera: Muscidae), is a mechanical vector of pathogens (bacteria, fungi, viruses, and parasites), some of which cause serious diseases in humans and domestic animals. In the present study, a systematic review was done on the types and prevalence of human pathogens carried by the house fly. Major health-related electronic databases including PubMed, PubMed Central, Google Scholar, and Science Direct were searched (Last update 31/11/2017) for relevant literature on pathogens that have been isolated from the house fly. Of the 1718 titles produced by bibliographic search, 99 were included in the review. Among the titles included, 69, 15, 3, 4, 1 and 7 described bacterial, fungi, bacteria+fungi, parasites, parasite+bacteria, and viral pathogens, respectively. Most of the house flies were captured in/around human habitation and animal farms. Pathogens were frequently isolated from body surfaces of the flies. Over 130 pathogens, predominantly bacteria (including some serious and life-threatening species) were identified from the house flies. Numerous publications also reported antimicrobial resistant bacteria and fungi isolated from house flies. This review showed that house flies carry a large number of pathogens which can cause serious infections in humans and animals. More studies are needed to identify new pathogens carried by the house fly.

Over the past decade, abnormalities have been documented in white-tailed deer (Odocoileus virginianus) in west-central Montana. Hypotheses proposed to explain these anomalies included contact with endocrine disrupting pesticides, such as imidacloprid. We evaluated the effects of imidacloprid experimentally at the South Dakota State University Wildlife and Fisheries Captive Facility where adult white-tailed deer females and their fawns were administered aqueous imidacloprid (an untreated control, 1,500 ng/L, 3,000 ng/L, and 15,000 ng/L). Water consumption, thyroid hormone function, behavioral responses, and skull and jawbone measurements were compared among treatments. Additionally, liver, spleen, genital, and brain imidacloprid concentrations were determined by an enzyme-linked immunosorbent assay (ELISA). Results indicated that 1) control deer consumed more water than treatment groups, 2) imidacloprid was present in the organs of our control group, indicating environmental contamination, 3) as imidacloprid increased in the spleen, fawn survival, thyroxine levels, jawbone lengths, body weight, and organ weights decreased, 4) adult female imidacloprid levels in the genitals were negatively correlated with genital organ weight and, 5) behavioral observations indicated that imidacloprid levels in spleens were negatively correlated with activity levels in adult females and fawns. Results demonstrate that imidacloprid has direct effects on white-tailed deer when administered at field–relevant doses.

Housefly, Musca domestica, has a long history of association with animals, which still are suffering from its harmful impacts. It occupies human and livestock premises and acts as a source of nuisance and annoyance to them. The present bibliographical study explains role of House fly as a disease vector of humans and livestock. This article highlights various aspects of the life of the said pest that includes its general description-morphology, biology, life cycle, its pest status and major control strategies. The pest is cosmopolitan in nature and shows holometabolous metamorphosis as it passes through all stages of development like egg, larva, pupa and adult which takes 10 to 14 days for its completion. Its life span is between 15 to 30 days. With respect to control strategies of the said pest, it was reviewed that chemical control is the most common and efficient technique but dependence on insecticide for fly control isrndecreasing due to increased insecticide resistance and environmental constraints. Biological control with natural enemies also provides reasonable results for outdoor control. Indoors control is mainly dependent on light and odor baited traps. Therefore combinations of several methods for the control of House fly population like Integrated Pest Management (IPM) program is recommended for the effective and efficient results.

Role of housefly (Musca domestica, Diptera; Muscidae) as a disease vector; a review

Broiler chicken’s production considered a very important sector of Egyptian poultry production. Diarrhea is a common problem that Threaten poultry production. There are many causes of broiler chicken’s diarrhea as; nutritional causes, infectious causes (viral, bacterial and parasitic). Larvae rarely infest and cause diarrhea in chickens but if present they irritate intestinal mucosa which causes a secondary bacterial diarrhea. In our investigation, intestinal myiasis was reported as uncommon cause of broiler chicken diarrhea in Egypt. The collected larvae were identified using scanning electron microscope study which revealed that; it is 3rd larval stage of M. domestica; creamy white in color; the length of the larvae ranged from 10-12 mm (10.5 ± 0.3); the anterior end contain the black colored cephalopharyngeal skeleton; the anterior spiracles present in the 2nd segment and had a number ranged from 6 to 8 rounded spiracular openings. The spines present in the group resembles the combs which present in the spinose area. The spinose comb contains from 5 to 9 spines which is small and triangular with slightly tapering ends. The posterior peritremes contain three snake or S- shaped or even tortoise openings; with central button; the peritreme was complete; the distance between the two peritreme ranged from 70- 100 μm in length.

Cotton aphid (Aphis gossypii) is a key pest of cotton crop. The indiscriminate use of insecticides and pesticides during 1930's and latter to control insects pests, developed resistance in cotton aphid against these chemicals resulting in outbreak of this pest. Cotton aphid has a major impact on quality and yield of cotton which emphasizes the need to manage this notorious pest. The main goal of this review is to highlight various strategies viz., biological, chemical and cultural control for cotton aphid management. The selection of suitable control strategy is made on by viewing the severity of cotton aphid outbreak. Furthermore, the role of transgenic crops in lowering cotton aphid population is also described. However, the preservation of the cotton aphid's natural enemies could be an ecologically sustainable method of maintaining the aphid population below threshold level.

Halophiles are salt loving microbes optimally growing at high concentrations of salt. Khewra salt mines of Pakistan provide extreme saline conditions where enormous halophilic microbial biota thrives. The present study aimed at isolation and molecular identification of bacterial strains from saline waters of Khewra salt mines. Using halophilic media, nine halophilic bacterial strains from saline water bodies were cultured and studied under optimized growth conditions (NaCl, pH and temperature). Bacterial growth at different NaCl concentrations was measured at 600nm wavelength, showing optimal growth at 1.5M NaCl. 769bp size 16S rRNA gene was amplified for molecular identification of bacterial strains. The amplified genes of the strains FA2.2 and FA3.3 were sequenced and their homology with other bacterial strains was analyzed. The results showed FA2.2 shared maximum homology with Bacillus anthracis strain while FA3.3 showed close resemblance with Staphylococcus saprophyticus subsp. bovis. Isolated halophilic bacterial strains possess potential for various biotechnological applications. They could be manipulated for synthesizing transgenic crops tolerating high salinity boosting the agricultural yield. Moreover extremozymes of these bacteria holds great industrial importance.
