Gyeongbuk Agricultural Technology Administration carried out the nation opinion research to mushroom industry in 115 of the citizen and the provincials from 10/17/2008 to 10/18/2008. Which was for both grasping the citizen’s opinion and habits and understanding farmers’. The result of the research is the following. 37.4 percent people preferred Lentimus edodes among the all respondents and 27.0 percent preferred Flammulina velutipes. As for the purchasing place, 57.4 percent buy them in large retail stores, 40.9 percent buy them in traditional markets. 67 percent of the respondents mainly use them in fall, 31.3 percent use them in winter. 88.7 percent of them mainly eat the mushrooms at home, 11.3 percent is at restaurants. 63.5 percent of them responded that the price of mushrooms was resonable, 26.1 percent answered that was expensive. In appearance, 27 percent of them chose yellow Flammulina velutipes as a goodlooking mushroom, 19.1 percent chose Lentimus edodes .

The techniques of IVM, IVF and IVC of canine oocytes may provide useful information for gamete salvage programs and the conservation of endangered canidae. This investigation has been made to determine the efficiency of in vitro maturation (IVM) as a basic experiment to study the development of canine oocytes after in vitro fertilization (IVF). The rate of oocytes developing to the MII stage was higher in the hormone treated group (10 IU/ml hCG+eCG, 14.7%, p<0.05) than in the control group (0 IU/ml hCG+eCG, 10.0%). The monospermy and pronuclear rates of canine oocytes were investigated after caffeine treatment on IVF. Canine oocytes were fertilized in the Fert‐TALP medium supplemented with 0, 10, 20 or 30 mM caffeine (Fert I, Fert II, Fert III or Fert IV, respectively). The highest pronuclear formation rate was obtained in the Fert I for 24 h IVF (6.7%, 6/89). Therefore, it is believed that unlike in other mammals, caffeine in canine IVF does not increase the efficiency of fertilization rate, and is not an important factor.

Spider mite is the most concerned pest in apple production. This study compared and analyzed the historical changes of two mite pests, Tetranychus urticae koch and Panonychus ulmi (Koch) in 16-30 representative apple orchards in the major apple production area; Gyeongnam, Gyeongbuk, and Jeonbuk province of Korea from 1992 to 2007. Monthly sampling of 100 leaves per orchard provided the basic data of population density of two mite species. Among those orchards, chemical spray history was also analyzed from four orchards, which could be representatives of IPM practitioners. It was found that overall population densities of T. urticae were higher than those of P. ulmi for 16 years. Before 2000, T. urticae was dominant over P. ulmi in most orchards. However since 2000, P. ulmi have occurred more than or as much as T. urticae.. Moreover, although there was large fluctuation of occurrences of two mite species over the years and localities, spider mite pressure appeared to decrease, in general. It seemed to relate the timing of ground cover management with pheromone-based IPM implementation nationwide from late 90s. Panonychus ulmi appeared to rise in April and July in general, fall in August, and go up again in the late season; September-October, while T. urticae appeared to begin to rise in June with July or August peak and sometime with late season second peak in October. Application frequency of acaricide has been dropped from four times in the late 1990s to 2.5 times in the late 2000s.
