Abstract

The present study was carried out to identify the breeding preferences of necrophagous flies to various types of mutton substrates i.e., fresh, cooked, salt, and turmeric powder treated and frozen forms. On day one of the experiment, the adult flies were recorded in group M1 and no flies were attracted to the remaining groups (M2 – M4). Fly eggs and first larval instars started to appear in the M1 group from the 2nd day onwards. By the 4th day onwards, adult flies, eggs as well larval instars were noticed in all the groups (M1 – M4). On the final day of the experiment, L3 stages were recorded with a varying number of all types of meat samples of mutton. In the present study, flies were attracted more immediately to fresh mutton meat than to remaining formulations. Other forms of mutton viz., cooked, salt, and turmeric treated and frozen samples were observed in the flies only after a day of its placement. The larvae obtained from fresh mutton (M1) samples were of Calliphora spp. (60%) and Lucilia spp. (40%). The majority of the dipteran larvae in cooked mutton (M2) were of Chrysomya spp. (73.3%) and the remaining (26.7%) were of Musca spp. In the third group of salt and turmeric powder treated mutton sample (M3), the obtained larvae were identified as Sarcophaga spp. (n=16) and the rest of the larvae were of Chrysomya spp. (n=14). The findings revealed that different Physico-chemical characteristics and also the proximate composition of mutton had significantly (P<0.05) influenced the breeding preferences of flies.
