Abstract
Mass releases of house fly Musca domestica (L) and stable fly Stomoxys calcitrans (L). Produced by manure piles accumulated nearby horse stables and dairy farm village in Abu-Graib provide continuous threat to inhabitants west of Baghdad. Timing of fly’s mass release in association with the presence of Escherichia coli in manure piles was examined at these locations. Experimental result indicated that flies survived during cold period of December and January in form of larvae deep in manure piles where temperature was around 15-17°C. Once the population of fly’s larvae started to increase by the second week of February, the concentration of E. coli was up to 80×106 CFU mL-1 in manure suspension. Later when larval population reached to a maximum number by the last week of April, the concentration of E. coli in manure sample dropped down to 38×102 CFU mL-1. Similar trend was observed with the proportion of E. coli to general bacteria present in manure samples where the percent decreased from 89% in early season to 1.5% when maximum number of larvae was recorded. The correlation coefficient (R) between the number of larvae and coli form bacteria was = -0.73657. These results suggest the association of larval development with the consumption of E. coli. Thus manipulation of bacterial community in manure piles may lead to possible eradication of fly’s seasonal release.
Highlights
From the bacterial community within the larval gut (Zurek et al, 2000; Perotti et al, 2001)

Summary
From the bacterial community within the larval gut (Zurek et al, 2000; Perotti et al, 2001). The muscoid flies persist as cosmopolitan pest of works (Glaser, 1924; Gerberich, 1948) had reported a human and of domestic livestock throughout much of positive relationship between bacterial activity and the world, in because of the ability of the house fly maggot growth, leading to the understanding immature stages to develop in variety of common that bacteria growth factors such as vitamins and organic materials such as manure, garbage and human sterols (Brookes, 1958) are essential for maggot west (Keiding, 1974). The survival is enhanced greatly in media supplemented with bacteria compared with sterile one Another perspective that involved the digestibility of bacteria in the intestinal tract was examined in house fly (Espinoza-Fuentes and Terra, 1987), stable fly (Rochon et al, 2004), blow flies (Greenberg, 1968) and black soldier fly (Qiaolin et al, 2008). Since land applications of dairy cattle and horse manures are a common practice and have served as primary source for soil fertilizers available to farmers in Iraq, this research was initiated to understand mass release of adult flies from manure piles west of Baghdad and possible manipulation of microbial population to suppress larval development
