To quantify the potential capability of transporting and passing infective
pathogens of some blowflies (Diptera: Calliphoridae), Mihályi's danger-index was calculated for seven species. The original equation
was modified to include synanthropic information to discriminate between asynanthropic,
hemisynanthropic, and eusynanthropic status. Three groups were recognized,
of which
Phaenicia cluvia
and
Musca domestica
proved the flies with lowest
index value (D = 2.93 and 3.00 respectively);
Cochliomyia macellaria
,
Chrysomya albiceps
and
Sarconesia chlorogaster
presented a significantly higher index
value (p
<
0.10; D = 4.28, 4.44 and 5.66 respectively) and
C. megacephala,
C. vicina and
P. sericata appear to represent the heaviest potential sanitary risk with the
highest index value (p
<
0.10; D = 15.54, 16.88 and 12.49 respectively).
