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.

Rearing media were selected for the production of sterile larvae of greenbottle blowfly, Phaenicia (=Lucilia) sericata (Meigen) which is widely used in maggot therapy. Eight media available in the market were used in this study. Egg hatchability was not different among the media. Survivorship of the larvae was higher in blood agar (BA), sabouraud dextrose agar, and brucella blood agar than the others. A higher content (20${\sim}$40%) of sheep blood in BA and chocolate agar increased the survivorship of larvae. The eggs and the early 3rd larvae could be stored for 12 days at $8^{\circ}C$ and for 15 days at $6^{\circ}C$ without decrease in hatchability and larval survivorship, respectively.

Because insect visitors was different depending on decomposition stage, dipterans occurred on chicken carcasses depending on postmortem intervals were compared by abandoned sites and decomposition from a serial study on arthropod occurrence from carcasses as forensic indicator. Species occurrence and decomposition of carcasses were different depending on abandoned sites (forest hill, open field, stream, greenhouse and roof), seasons (spring, summer, fall and winter), and situation (burying and non-burying). Development of carcass decomposition was faster at all sites in summer, carcass in greenhouse in winter, and unburied carcasses. Although visiting time of blow flies (Calliphoridae) (Phaenicia sericata, Lucilia illustris, Lucilia sp., Chrysomyia pinguis, and Chrysomyia megacephala) was different depending on abandoned season, their adults were generally collected from carcasses within 2 days. However, there were no visited flies at fresh stage of buried carcasses. The flesh flies (Sarcophagidae) were collected from all sites and seasons, and much faster from unburied carcasses than buried carcasses. Those were collected earlier from carcasses in greenhouse than other sites and occurrence was also shorter. In greenhouse, occurrence time of flesh flies were different depending on season; spring and summer - from fresh to active decay stage, fall - fresh to active decay stage, and winter - advanced decay to remains stage. Calliphora lata, Tricerotopyga calliphoroides, and Aldrichana grahami were dominant species and occurrences were different from other flies. These flies were active mainly from fresh to active stage. Larvae of sarcophagid flies were occurred earlier than those of calliphorid flies on buried carcasses.

Maggot therapy (MT) has been re-introduced for non-healing wounds such as pressure sore, diabetic and necrotic ulcers, as well as infected surgical wounds, burn, and trauma injuries since early 1990s. For the production of sterile maggot of proper developmental stage, Lucilia sericata were studied on developmental periods of immature stages on liver agar medium under six different temperatures such as 15.4, 20.6, 22.5, 26.2, 29.1, and $33.0^{\circ}C$, and adult longevity and egg Production under $29^{\circ}C$. The periods of eggs and larvae of the 1st and the 2nd instars were shortest at $33^{\circ}C$ by 9.0, 14.0 and 18.6 hours, respectively. The periods of the 3rd instar larvae and pupae were shortest at $29.1^{\circ}C$ by 285.0 and 171.0 hours, respectively. Developmental zero point and total effective temperature far the development of each stage were calculated based on the developmental periods. Adults of both female and male lived more than one month. Females laid an average of 338.5 eggs through 2.7 times of egg laying throughout her lifetime.
