The Difference in the Development of Green Flies Larvae (Calliphoridae) in the Carcass of Mice (Mus Musculus) between Terrain and Berastagi

Introduction

Forensic entomology, a branch of entomology that deals with the application of insects in forensic science, has become increasingly important in the field of criminal investigation. One of the most crucial insects in forensic entomology is the green fly, classified in the Calliphoridae family. These insects are known to quickly colonize carcasses after death, making them a valuable tool in estimating post-death time. However, the development of insects, including flies, is strongly influenced by various food and environmental factors, one of which is the geographical location. This study aims to compare the duration of the development of the life cycle of green flies larvae in two different locations, namely terrain and Berastagi.

Background

Green flies, also known as blowflies, are one of the most common insects found in carcasses. They are attracted to the smell of death and can lay their eggs on the carcass within a short period after death. The eggs hatch into larvae, which feed on the carcass and grow rapidly. The development of green flies larvae is a critical factor in estimating post-death time, as it can provide valuable information about the time of death. However, the development of insects is influenced by various factors, including temperature, humidity, and food availability.

Methodology

This study used a descriptive observational approach with a prospective research design. The variables studied were measured simultaneously during the research process. The study used primary data to determine the duration of the life cycle of the larvae in each of the three samples of mice (Mus musculus) aged 2-3 months with a weight of 20-25 grams, which is taken from the location of the field and Berastagi. The process includes cutting on the neck of mice and incisions 5 cm in the abdomen to observe the changes that occur, and examine each phase of the development of green flies larvae from eggs to pupa, and identify flies contained in the sample.

Results

The results showed a significant difference in the development of green fly larvae from the Calliphoridae family in the Medan and Berastagi regions. In Medan, the duration of larval development from the egg phase to the imago phase is 208 hours (8.6 days), while in Berastagi it reaches 272 hours (11.3 days). Thus, there is a difference in the development of green flies larvae between the field and Berastagi which is 64 hours (2.5 days).

Discussion

Differences in the duration of the development of green flies larvae in these two locations can be influenced by various environmental factors. One of the most relevant factors is air temperature, which can play a major role in metabolism and larvae growth. Medan, which is located in the lowlands with higher temperatures and higher humidity, can accelerate the process of larvae development. Meanwhile, Berastagi, which is located in the highlands, has a cooler temperature that can slow down the development process.

Another factor that can influence is the existence of food sources and microorganisms that are around the location. The wreck as a breeding medium has a different composition in both places, which may also affect the speed of larval development. In the context of forensic entomology, understanding of this difference is very important, especially in an effort to estimate the time of death accurately in various locations.

Conclusion

This research not only highlights the importance of green flies in forensic entomology, but also emphasizes that environmental factors and geographical locations have a significant effect on larvae development. This discovery is an important foundation for further research, both in the field of forensic and in insect ecology studies.

Recommendations

Further research is needed to investigate the effect of other environmental factors on the development of green flies larvae. This includes studying the effect of temperature, humidity, and food availability on the development of green flies larvae. Additionally, research is needed to investigate the application of green flies in forensic entomology in various locations.

Limitations

This study has several limitations. The study only investigated the development of green flies larvae in two locations, and did not investigate the effect of other environmental factors on the development of green flies larvae. Additionally, the study only used primary data and did not use secondary data to support the findings.

Future Directions

This study provides a foundation for further research in the field of forensic entomology. Future research should investigate the effect of other environmental factors on the development of green flies larvae, and should also investigate the application of green flies in forensic entomology in various locations. Additionally, research is needed to investigate the use of green flies in estimating post-death time in various locations.
