  • The pinewood nematode Bursaphelenchus xylophilus (Nematoda: Parasitaphelenchidae) poses a serious threat to pine forests in Europe and East Asia, leading to a debilitating pine wilt disease. Infected pine trees in Korea are generally fumigated or crushed to small wood chips after felling. Although pine wilt disease often recurs in pest management sites, there are no adequate means to monitor the effectiveness of pest control measures in those sites. Recently, a male-produced aggregation pheromone, 2-(undecyloxy)ethanol, was shown to be useful for attracting several Monochamus species, which are vectors for the pinewood nematodes. In this study, we investigated the abilities of 2-(undecyloxy)ethanol at three different doses (175, 350, and 700 mg), as well as host plant volatiles (α-pinene and ethanol), to attract M. alternatus (Coleoptera: Cerambycidae) at a pine forest in Pohang, Korea where infected pine trees had been cut down and fumigated. Twenty-seven M. alternatus were captured in cross-vane panel traps made of polyethylene terephthalate bottles and acrylic sheets. The results indicate that a high dose of 2-(undecyloxy)ethanol (700 mg per trap) is the most effective for attracting M. alternatus. The aggregation pheromone could be used to monitor the effectiveness of pest control measures as well as M. alternatus populations.

  • Wood boring insects collected around bait logs of Pinus densiflora and Pinus koraiensis were 45 species from 4 families, which were composed of 21 species of Cerambycidae, 9 species of Curculionidae, 2 species of Rhynchophoridae, and 13 species of Scolytidae. Parasitic or predatory insects were 35 species from 15 families in 6 orders. Among the natural enemies, 2 parasitoids of Dolochomitus nakamurai and Echthus reluctator, and 2 predators of Trogossita japonica and Thanassimus lewisi, were observed frequently attacking a vector insect, Monochamus saltuarius, which has been known to transmit pine wood nematode. Bursaphelenchus xylophilus. Adults of D. nakamurai and E. reluctator emerged during early April and early May. Both parasitoids laid eggs on M. saltuarius prepupa and papa, which passed winter inside the pupal chamber. The general predators, T. japonica and T. lewisi, preyed actively during April and October, and attacted almost all of developmental stages of wood borers.

  • The toxicity of benfuracarb and ${\lambda}$-cyhalothrin on oak longicorn beetle, Moechotypa diphysis was investigated in terms of residual effect and control efficacy in the field. Mycelial growth inhibition of Lentinula edodes was also investigated in the laboratory. Benfuracarb and ${\lambda}$-cyhalothrin showed 100% of control values and over 90% residual activities of benfuracarb and ${\lambda}$-cyhalothrin were continued for 15 and 20 days after treatment, respectively. Benfuracarb and ${\lambda}$-cyhalothrin did not affect the mycelial growth of L. edodes Imhyup 1 variety. These results indicate that benfuracarb and ${\lambda}$-cyhalothrin might be used for the control of M. diphysis adults in the field.

  • Movement of adult Monochamus alternatus was investigated on young black pine, Pinus thunbergii, trees for about one month in a screen cage. Number of pine trees to which M. alternatus females and males moved during the experimental period was $6.4{\pm}1.4$ and $7.2{\pm}1.5$ out of 15 trees, respectively. Adult females and males moved to $0.2{\pm}0.1$ and $0.3{\pm}0.1$ tree per day, respectively. A 74.6 and 80.7% of adult females and males moved at night (17:00-08:00) to other trees. After moving, most beetles (72.6% of females and 76.0% of males) stayed on the tree to which they moved for one to two days. Some beetles stayed for up to seven days.

  • As the pest of the Letinus edoeds, five insect species and six animal species are investigated injuring the fresh mushroom. Of these, insect and animals, Achorutes armatus, Scaphidium amurense and Philomycus confusa caused severe damage to mushroom fruitbody, and a greate deal of damage was done to mushroom lamella by mites (Rhizoglyphis sp., and Histiostoma sp.). As the pest of Lentinus edodes bed logs, two insect species from immature bed logs, eight insects and one isopod species from matured bed logs were investigated. Of those, Moechotypa diphysis was found to be the most injurious species from both immature and matured bed logs. As the pest of Pleurotus ostreatus, six insects and the two mite species were investigated from sporophore. Of those, Lycoriella sp. and Mycophilla sp. are considered to be very serious. while two insects and five mite species were investigated from the mushroom bed. Of those, one insect (Lycoriella sp.) and two mites (Histiostoma feroniarum and Throglyphus bankslogior) found to be abundant and caused serious damage.
