  • The average number of oviposion scars in lower (facing the Land) and upper part (facing the Sun) of P. koraiensis logs were $16.3{\pm}13.9$ and $3.3{\pm}3.6$, respectively. Oviposition preference of Monochamus saltuarius adults was lower part of Pinus koraiensis. Estimated average number of larvae and egg from oviposition scars ($64.7{\pm}23.8$) in P. koraiensis logs was $18.8{\pm}10.0$ in the laboratory condition. However, oviposition scars were $63.6{\pm}31.1$ and average number of larvae and egg was $2.0{\pm}2.6$ in field condition. When we fed with inner bark (phloem) and xylem of P. koraiensis, body weight of M. saltuarius larvae was normal. However, when we only fed xylem of P. koraiensis, body weight and size were reduced but they were recovered after feeding inner bark (phloem). Esterase isozymes were assessed from larvae fat body of M. saltuarius and Est1 were specifically activated when we fed with inner bark (phloem) and xylem.

  • The purpose of this study was to investigate the effects of p. Linteus and C. militaris supplement on lactate, phosphorous, ammonia, MDA(malondialdehyde), GPX(glutathione peroxidase) and TAS(total antioxidant status) following $VO_{2max}$, and 85% $VO_{2max}$ exercise. The 15 male college students were divided into three groups: 5 P. liteus supplied(PL), 5 C. militaris supplied(CM), and 5 placebos supplied(PB) and compared the differences between supplement before and after. Obtained results were as follows: In the exercise performance time, there were no differences in PL, CM and PB groups. Regular supplement of P. linteus or C. militaris partially reduces fatigue induction factors. Also, P. linteus or C. militaris supplement decreases MDA, increases GPX and TAS. Therefore, it can be concluded that P. linteus or C. militaris supplement not only have a pharmacological effect for clinical treatment, but also have a maintenance effects on the tissue oxidant-antioxidant system after exercise.
