Almost none of these factors correlated strongly with whether a species or subspecies was boldly striped, subtly striped, or stripeless — except for the prevalence of biting flies.
After examining 29 different environmental factors, including prevalence of biting flies, heat and predators, the researchers found that temperature had the strongest correlation with stripe patterns.
Boulgou Province was previously unsuitable for livestock farming because of the prevalence of tsetse flies.
To determine the prevalence of Campylobacter in flies around the broiler house, a total of 96 flies were captured singly within a distance of 50 m from the house by rackets equipped with small disposable plastic bags.
Moreover, a high prevalence of Campylobacter-infected flies captured in a broiler house has been found (11).
The prevalence of the tsetse fly defeated attempts to raise beef and dairy cattle until 1980, when tsetse-resistant cattle arrived from other parts of Africa.
The distribution of human Leishmaniasis is co-extensive with the prevalence of the sand fly vectors and thus constrained by climate, geography and altitude (Figure 1).
Because pest flies may act as vectors of STEC O157 H7 (7 ) and are abundant at fairs, we also estimated STEC O157 H7 prevalence in flies at fairs.
We are unaware of any studies that have correlated the abundance of flies with the prevalence of Campylobacter spp. positive broiler chicken flocks.
On the contrary, fly screens could have other beneficial effects; for instance, fly screens could reduce the prevalence of costly poultry diseases carried by flies.
To examine the prevalence of C. burnetii in field-collected flies, we tested flies from farms, forests, ranches, and zoos.
