Perbedaan Lama Perkembangan Larva Lalat Hijau (Calliphoridae) pada Bangkai Mencit (Mus Musculus ) Antara Medan dan Berastagi

Abstract

Background: The green Bottle fly (family: Calliphoridae) is the most important taxon in forensic entomology. These flies immediately colonize corpses immediately after death. Research insect larval development is useful for estimating post-mortem times. However, the development of insects, including flies, is greatly influenced by food and environmental factors, one of which is geographical location. In this study, the aim was to see a comparison of the length of development of the life cycle of green fly larvae and the time difference between geographical types between Medan and Berastagi. Method: Using descriptive observational research with a prospective research design. Variables are measured at the same time as the research takes place. Research using primary data to determine the duration of the larval life cycle in each of 3 samples of mice (Mus musculus) aged 2-3 months and weighing 20-25 grams at the Medan and Berastagi locations. A dislocation was carried out on the mice neck and a 5 cm incision was made on the mice stomach and the changes in the sample were seen by examining each phase of the life cycle of the development of green fly larvae from egg to pupa and identifying the flies in the sample. Results : There is a comparison of the development of green fly larvae of the Calliphoridae family in the Medan and Berastagi areas. The development of Calliphoridae fly larvae in Medan from egg to imago phase is 208 hours (8.6 days) while in Berastagi it is 272 hours (11.3 days). The difference between the development of calliphoridae fly larvae between Medan and Berastagi is 64 hours (2.5 days).
