  • 많은 해충이 과수의 다양한 조직을 가해하여 국내 과수산업을 위협하고 있다. 경제적으로 중요한 과수 해충의 방제는 일반적으로 화학 살충제에 의존하고 있다. 환경과 인류 건강에 미치는 살충제의 영향에 대한 우려가 증가함에 따라 환경 친화적인 해충방제 전략이 시급하게 필요한 실정이다. 과수 해충의 페로몬은 교미교란이나 대량포획과 같이 환경적으로 안전한 방제 체계를 끌어낼 수 있다. 본 종설은 과수 해충 51종에서 알려진 페로몬의 유형과 성분을 요약한다. 장님노린재과, 진딧물과, 깍지벌레과, 가루깍지벌레과, 풍뎅이과, 혹파리과 및 씨살이좀벌과에 속하는 14종과 나비목의 26종은 암컷이 성페로몬을 생산하여 수컷을 유인한다. 반대로 호리허리노린재과, 노린재과, 총채벌레과 및 하늘소과에 속하는 11종은 수컷이 집합페로몬을 생산하여 암컷과 수컷 모두를 유인한다. 향후 과수 해충 관리에서 페로몬과 다른 신호화학물질의 사용을 확대하기 위해서는 새로운 해충의 페로몬, 주요 해충의 카이로몬, 장기간 페로몬 방출용 교미교란제 및 대량포획을 위한 트랩 디자인과 트랩 설치에 관한 연구가 필요할 것으로 보인다.

  • Densities and larval food habits of Holotrichia titanis belonging to Melolonthinae, and of Anomala corpulenta and A. mfocuprea belonging to Rutelinae, collected from surroundings of ginseng fields, were investigated to determine potentia]s as ginseng pests in scarabaeids. H. titanis had similar food habit to the ginseng pests, H. morosa and H. diomphalia, although the density of H. titanis was relatively low during the period of survey, which indicates that the scarabaeid may have potentials to be a major pest with build-up or the population in the fields. However, A. corpulenta and A. rufacuprea with higher populations than H. morose and H. dicmphalia had no or low potency as ginseng pests since they had little preference to ginseng roots or did not feed on these. The latter two species in Rutelinae showed different food habits in relation to dead organic matter.

  • A survey to assess the diversity of wound-associated Ophiostomatales and Microascales, the so-called ophiostomatoid fungi, on Korean native trees, was undertaken in 2017. Wounds were artificially created, and a fungus resembling a species of Sporendocladia was consistently isolated from the exposed cambium and inner bark of artificially induced wounds on Quercus variabilis. Morphological examination and DNA sequence comparisons based on the internal transcribed spacer (ITS) and 5.8S regions of the rDNA confirmed the identity of the fungus as Sporendocladia bactrospora. This is the first report on S. bactrospora occurring on Q. variabilis in Korea.

  • In this study, we propose a big data set of strawberry pests collected directly for diagnosis model learning and an automatic pest diagnosis model architecture based on deep learning. First, a big data set related to strawberry pests, which did not exist anywhere before, was directly collected from the web. A total of more than 12,000 image data was directly collected and classified, and this data was used to train a deep learning model. Second, the deep-learning-based automatic pest diagnosis module is a module that classifies what kind of pest or disease corresponds to when a user inputs a desired picture. In particular, we propose a model architecture that can optimally classify pests based on a convolutional neural network among deep learning models. Through this, farmers can easily identify diseases and pests without professional knowledge, and can respond quickly accordingly.

  • This study was carried out to investigate the status of spot damage by fruit piercing pests and the kinds of these pests on yuzu (Citrus junos) fruit in Koheung, the most chief producing district of yuzu fruit in Korea, from ’97 to ’99. The extent of spot damage by fruit piercing pests on yuzu was increasing in recent years. This damage of fruits was severe in the lower canopy than the high one from ground and intercropping groves between yuzu trees had a greater damage to compare with single cropping of yuzu. Spot damage of yuzu fruit was occurred mainly from late September to early November when yuzu fruit is enlarging and coloring yellow. The blackish concave spot on yuzu fruit surface was appeared in 3 days after introduction of Riptortus clavatus into a netted cage containing one yuzu fruit and the diameters of this spot was 8.3 mm. At 10 days after introduction, this spot changed into milky-white with 9.2 mm diameters. One concave spot has contained oil cells by 17.7 and its external appearances has unchanged until harvest. The kinds of piercing pests of yuzu fruit were investigated with 3 orders, 16 families and 37 species. These pests were classified by 11 species of bugs, 5 species of hoppers and 21 species of moths. Among them, dominant species were Physopelta gutta, Halyamorpha halys, Empoasca vitis, Aedia leucomelas, Agrotis tokionis, etc. Macroglossum bombylans and Acherontia s쇼x are newly confirmed species as the fruit piercing moths in Korea.
