Seasonal activity of the native dung beetles, Copris ochus (Motschulsky) and Copris tripartitus Waterhouse, was studied in Jeju Island, Korea. Reproductive condition and breeding cycles of adult females were determined using physiological age-grading techniques to assess the proportions of newly emerged, nulliparous and parous beetles, and those resorbing oocytes. C. ochus appears to be univoltine. Its main period of adult emergence occurs in summer rather than in spring (March–May), as was previously thought. The female population consisted of the complete range of reproductive age classes in August– September. C. tripartitus also appears to be univoltine. However, this species has two adult activity periods: a peak activity in spring when most oviposition occurs, and another in autumn when the new generation emerges. With the onset of winter, C. tripartitus adults cease reproductive development and females over winter in a nulliparous stage.

Paratlanticus ussuriensis eggs overwinter by entering diapause, which can be prolonged to more than 1 year depending on environmental conditions. To determine temperature effects on diapause duration of P. ussuriensis eggs, the rates of embryonic development and hatching were compared at various temperatures conditions by measuring embryonic stages and egg weights. Most eggs stayed in a very young stage (blastoderm formation, stage 4) when reared at 15 and 20 °C, 10–30% eggs developed into middle or late stages when reared at 25 °C, and most embryos developed fully (stage 23/24) when reared at 30 °C. Egg weight at 30 °C was 1.5 times higher than those reared at 20 °C. Chilling induced hatching in embryos at stage 23/24. Chilling caused stage 4 embryos to develop into stage 24, but they failed to hatch in response to a second warm period. Thus, P. ussuriensis eggs can overwinter either as young embryos (initial diapause) or as fully-developed embryos (final diapause). Eggs that experience an initial diapause overwinter again the second year in a final stage diapause. The post-diapause period was shorter when embryos overwintered in a final stage diapause. The hatching rate was highest in a temperature range of 7.5–15 °C. Our results suggest that temperature is an important environmental factor for the control of prolonged diapause in P. ussuriensis and initial diapause plays an important role in the control of its life cycle.
연구보문 : 토양환경 ; 우분 분해에 대한 지렁이와 소똥구리의 상호작용

우분의 분해에 있어 소똥구리와 지렁이를 함께 처리한 구에서 단독으로 소똥구리와 지렁이를 처리한 것 보다 분해율이 높았고, 지렁이와 소똥구리가 우분 분해 활동을 한 다음에 식물체를 파종했을 때 식물체 생장은 비료를 처리한 것과 동일한 효과가 인정되었다. 우분 함수율 78%까지는 소똥구리에 의해 분해 활동이 일어나며, 30%까지는 지렁이에 의해, 30% 이하에서는 두 동물군 모두 분해 활동을 하지 않았다. 소똥구리와 지렁이에 의해 운반된 우분은 초기 우분의 약 72%이며, 이중 10.2%는 소똥구리의 brood ball 형성에 이용되었다. 지렁이의 활동이 소똥구리의 brood ball 형성에 저해요인이 되지 않았고, 소똥구리의 활동 또한 지렁이의 생육에 영향을 미치지 않아 지렁이와 소똥구리는 우분에서 공간적 분포를 같이 하면서 먹이 경쟁을 하기 보다는 상호보완적인 작용을 하는 것으로 밝혀졌다. The effect of earthworm and dung beetle on cattle dung pat decomposition was assessed by combining quantification of earthworm density and with or without dung beetle in pats and measurements of the decomposition rate of these pats. Cattle dung decomposition rate was higher in the pots treated with both earthworm and dung beetle than in the pots with either earthworm or beetle alone. After dung beetle and earthworm activity, the growth of oat in earthworm with dung beetle treatment was similar effect with fertilizer treatment. Dung beetle was responsible for dung decomposition until 78% moisture content in the dung, earthworm was responsible for up to 30% moisture of dung, and two group were not shown any activity for decomposition less 30% moisture content of dung. Therefore dung in the different periods could be broken down by each group. The disappearance and conveyance of dung by earthworm and dung beetle was 72% of the initial dung amount. 10.2% of 72% dung was used making brood balls by dung beetle. Earthworm activity was not an impediment on making brood balls by dung beetles. The interaction of earthworm and dung beetle may have a complementary cooperation rather than competition in the same dung pat. Indeed, development of earthworm accelerate to coexist with dung beetles instead without dung beetles. From this result, maximum benefits of the effective earthworm and dung beetle can be achieved, it is needed to preserve population of earthworm and dung beetles in pasture to sustainable agricultural environment.

Development of Copris tripartitus (Coleoptera: Scarabaeidae) in Two Different Rearing Media
Bang, Hea-Son,Wardhaugh, K.G.,Hwang, Seok-Jo,Kwon, Oh-Seok 한국곤충학회 2003 Entomological Research Vol.33 No.3
Like many other sub-social insects, Copris tripartitus Waterhouse requires parental care during the development period in the brood balls. Mass-rearing is achieved by using indoor rearing systems and adding more dung after taking away the brood balls containing eggs. Without parental care, larvae are often affected by desiccation, as well as by fungal or sciarid fly intrusion of the brood balls. This study developed a good substitute for brood ball rearing medium. A significantly greater number of progeny survived to adulthood from broods produced by beetles reared on vermiculite medium ($90.69{\pm}10.98%$) than on peat moss medium ($44.82{\pm}13.92%$). Results of the study suggest that to protect the brood balls from desiccation and to produce healthy adults, 15-20% moisture content vermiculite must be used as brood ball rearing medium for most species reared in the laboratory.
