Effect of the carrion weight and temperature on the attraction of Calliphora vicina

The experiment was carried out in the city of Kut, Al-Karadiya zone, Iraq on 9th May and 18thFebruary 2020, to investigate the effect of corpse weight and temperature on the attraction ofCalliphoravicina. The speed and density of C. vicinaadults were recorded on May 9th, 2020 where the density of insects was 9.5% in the corpse weighing 20-15kg, while the best time was morning (39±2°C), with an average of 9-12 insects. The percentage of presence in the corpse weighing 5-3kg was 3.3%, while the best time for their presence was morning (39±2°C) with an average of 3-5 insects. The temperature had a clear effect on the attraction of C. vicinato the carrions, where 39±2°C (morning) was the most appropriate degree for the attraction for all weights (7.1%), while 42±2°C (noon) was the lowest (4.8%). On the 8th of February, the presence rate of C. vicinaon the carrion 20-15kg was 3.0%, with the best time at noon (18±2°C) with an average of 4 insects. The percentage of its presence on the corpse 5-3kg was 0.3%, with the best time at noon (18±2°C), with an average was 1 insect. The temperature of 18±2°C (noon) was the best in all weights of the carrion, with a rate of 2.6%, while its presence was 1.3% at 16±2°C (morning).
