The study was conducted to investigate the effects of post-incubation period and temperature treatment conditionsduring incubation on the uniform primordia formation and cultural characteristics of oyster mushroom (Pleurotus ostreatus). Threekinds post-incubation period; 25, 30, 35 days and control were applied for 30 days while two kinds incubation roomtemperature 23oC and 26oC and control were used 20oC. The substrate temperature during pre-incubation was of ‘Suhan No. 1’and ‘Gonji No. 7’. Oyster mushroom varieties tended to increase between 24oC to 26oC at 11 to 15 days after inoculation andthen they were maintained in treatment temperature during post -incubation period. The CO2 occurrence was at the highest at6,500ppm for ‘Suhan No. 1’ and 5,800ppm for ‘Gonji No. 7’ at the time of the highest temperature increase. The ratio of un-uniformal primordia formation and the ratio of non-commercial fruit body were reduced by 40%, 10.5%, respectively comparedto control for ‘Suhan No. 1’ when in the post-incubation temperature was 26oC, and incubated for 10days and 15daystreatment. Also, ‘Gonji No. 7’ was reduced by 19%, 9.5%, respectively when in the post-incubation temperature was 26oC, andincubated for 10 days treatment. Therefore, the higher post-incubation temperature of room and longer post-incubation periodresulted in the higher percentage of primordia formation of two cultivars.

Propylea japonica is small ladybug(approximately 4-5mm) and is met with everywhere in Korea. When there was no aphid, the survival rate of P. japonica was 0% among another instar bugs and 26.7～32.8% among same instar bugs after 48 hours. When there were sufficient aphids, the cannibalism of P. japonica was low, so the survival rate of P. japonica was 78.6～95.8% among another instar bugs and 80.6～100% among same instar bugs after 48 hours. In the comparison of the number of eggs at different oviposition site, P. japonica preferred the corrugated cardboard. In experiment using T-tube, the rate of decoy was 81% at cotton aphid compared with pepper leaf and 62% at cotton aphid compared with artificial diet. In the artificial diet using shrimp and chicken liver, the developmental period from egg to adult was 17days and the survival rate from egg to adult was 66.7% but the vitality was not good. These data suggest that P. japonica can be used effective natural enemy for control of aphids and is needed to research about artificial diet, mass rearing system and control effect in field.

After the test of specific characters from 2008 to 2011, it was finally selected and named. ‘Love Letter’ was developed because of distinctive characters such as growth uniformity and high yielding potential. A standard type with large sized flower, It has red(Red Group 46A) color flower. ‘Love Letter’ takes 43 days from pruning to blooming and cut flower productivity was 152 stems/m2 in a year. The stems of cut flower have no thorn and the length was long with 70.5 cm. It has 9.3 cm in flower diameter and 32.4 in petal numbers per flower. Vase life of the this cultivar could be as long as 12 days.
