검정파리(Calliphoridae)에 의한 폐가축의 분해 촉진 = Biodegradation of Abandoned Livestock by Blow Flies (Diptera: Calliphoridae)

국문 초록 (Abstract)

시식성 파리에 의한 폐가축의 분해촉진 가능성을 폐사돈과 폐계를 사용하여 실험하였다. 2007년 5월 30일에 야외에 방치한 폐사돈(36kg)은 23일 후에 완전히 분해되었다. 2007년 7월 25일 폐계(3.4kg)를 상자에 넣고 문을 닫아두었을 때보다는 열어 놓았을 때에 야외의 파리가 유인되어 산란함으로써 더 빨리 분해되었다. 폐계를 상자에 방치한 지 6일 후의 무게는, 문을 3일간 열어두었을 때에는 0.6kg으로 감소하였으나 문을 닫아두었을 때에는 3.0kg으로 분해 속도가 느렸다. 2007년 10월 1일 폐계를 상자에 넣고 구리금파리(Lucilia sericata)를 50쌍 접종하였을 경우에는 3.2kg이던 것이 접종 22일 후에 1.0kg으로 줄어들었으나, 암:수 200:100 마리를 접종하였을 때에는 3.4kg이던 폐계가 11일 후에 0.8kg으로 감소되었다. 따라서 폐가축은 파리류에 의해서 분해가 촉진될 수 있으며, 폐가축 분해를 위한 검정파리류의 실용화를 위해서는 더 다양한 크기의 폐가축을 대상으로 더욱 다양한 환경조건 하에서 분해속도를 조사해야 할 것으로 생각된다.

A possible rapid biodegradation of abandoned livestock was tested by using the dead pig and chicken. The dead pig (36kg) was completely decomposed after 23 days of placement in the open field during June 2007. When the door of a cage in which a dead chicken (3.4kg) was placed was opened, a lot of flies were attracted to the chicken and layed eggs on the chicken. As the result the chicken was decomposed down to 0.6kg after 6 days of placement in the open field, On the other hand when the door was closed, the decomposition was very slow. The chicken weighed 3.0kg even after 6 days. An experiment conducted during October 2007 showed that decomposition speed depended on the number of inoculated flies. When 50 pairs of Lucilia sericata flies were inoculated to 3.2kg chicken, it was decomposed down to 1.0kg after 22 days in the field. However, when 200 female and 100 male flies were inoculated, the 3.4kg chicken was decomposed to 0.8kg after 11 days in the field. A 10,858 pupae (371.2g) was produced from the latter chicken. These pupae may possibly be used as a feed for fish and fowl. From these results it is considered that further research is needed to commercialize the blow flies for the rapid decomposition of an abandoned livestock of diverse size under diverse environment.
