To date, Periphyllus allogenes is known only in Korean peninsula, has been reported with morphological characteristics about only the aptera viviparous generation. In this study, we collected fundatrix and alate viviparous female individuals of P. allogenes samples from Gapyeong-gun, and Hongcheon-gun in Korea between 2021 and 2022. Herein, we provide new descriptions, measurements, distributions, host plants, and photographs of unknown morphs, fundatrix and alate viviparous generations of P. allogenes.

Nicobium castaneum belonging to the family Anobiidae of Coleoptera was found in Jeju Folk Museum in 2006, Miribeol Folk Museum in 2007, and a bier preserved in the bier house of Jeju in 2008. We found that this species did considerable damage to the several wooden cultural properties. For Identification and pest management to conserve wooden cultural properties from this anobiid species, we report morphology of adult and damage pattern (shape of exit holes from the host, tunnels and their excrements etc).

Treatment of juvenile hormone analogue(JHA) at the 5th instar larvae prolonged the duration of adult development one to one and half days as well as the elongation of feeding time with the increasing of larval body weight. Morphological observation and protein analysis in hemolymphs, integuements, alimentary canals, fat bodies and ovaries also revealed that the development of these tissues and organs for adultation are affected by the JHA treatment.

An aphid species, Glyphina betulae( Linnaeus, 1758), which has been known only in western Paleoarctic, is recognized from Mt. Baekdu-san, North Korea. Besides the descriptions and illustration for apterous viviparous female and alate viviparous female, brief biology, host plahts and distribution are discussed. This is the first record of the genus Glyphina in Korean Peninsula.

This study was conducted to investigate the morphological characteristics, overwintering sites and behavior for each stage of Oligota kashmirica benefica (Coleoptera: Sthphylinidae). Egg was oval type, yellow, 0.3 mm size. Larva exuviated 3 times and the last (3rd) instar, length 1.6 mm, wide 0.4 mm, became dermata pupa in soil. Adult was lightish dark-brown, and coriaceous forewing covered a half of abdomen. O. kashmirica benefca mainly overwinters with adult at Japanese cedar (Cryptomeria japonica) windbreaks of orchards, but it did not diapause in greenhouse during winter.

국내의 대부분 도시하천에 우점하여 나타나는 깔따구속(Chironomus)은 국내에 밝혀진 깔따구과(Chironomidae)중에서 가장 다양한 종다양성을 보이며 개체가 상대적으로 크고 사육이 용이하여 생태학, 독성학 및 분자유전학적 재료로 널리 쓰이고 있다. 그러나 깔따구속 각 종간의 성충 및 유충의 형태적 유사성으로 인하여 많은 분류학적 어려움을 안고 있다. 특히 국내에 분포하는 노랑털깔따구(C. flaviplumus)와 요시마쓰 깔따구(C. yoshimatsui)는 성충과 유충에 있어서 많은 변이가 나타나 여러 문헌에서 혼동되어 쓰이고 있는 실정이므로 그들의 분류가 시급한 실정이다. 본 연구에서는 전형적인 한국의 도시하천인 서울시 중랑천을 대상으로 그곳에 우점하는 장수깔따구(C. plumosus), 구슬등무늬깔따구(C. circumdatus), 등깔따구(C. dorsalis), 안개무늬깔따구(C. kiiensis), 요시마쯔깔따구의 형태적 유사성 및 차이점을 비교하였다. 채집된 요시마쯔깔따구는 배무늬 및 생식기 형태에서 다양한 변이를 보였으며, Wing length 2.77$\pm$0.17mm (2.53-2.94), Leg ratio(L.R.)가 1.60$\pm$0.05, Antenna ratio(A.R.) 2.84土0.10의 값을 나타냈다. 일부 개체는 A.R.이 3.35로 국내산 노랑털깔따구(A.R. 3.50$\pm$0.11, Ree & Kim, 1981)와 혼란될 수 있으나 이는 요시마쯔깔따구 군집내의 변이로 생각된다. 국내에 기록된 요시마쯔깔따구와 노랑털깔따구는 일본산 요시마쯔깔따구와 노랑털깔 따구가 A.R.값이 각각 3.1과 4.0(Sasa, 1978)으로 구별되는 것과 달리 A.R.에서 큰 차이가 나타나지 않고 배무늬 및 생식기 형태의 변이 폭이 크게 나타나므로 앞으로 전국적인 지역에 분포하는 상기 두 종의 개체군에 대한 비교 연구가 필요하다.

The antennal sensilla of the adult male and female ladybird beetle, Harmonia axyridis (Coleoptera: Coccinellidae) were examined by scanning electron microscopy. Nine types of sensilla were characterized and grouped into 5 morphological classes: $B\ddot{o}hm$, basiconic, chetiform, coeloconlc, and trichoid sensilla. $B\ddot{o}hm$ sensilla were localized on the scape and pedicel, part of the ventral and dorsal proximal side. This placement suggests a role in proportion of antennal position and movement. Basiconic and chetiform sensilla were divided into 3 subtypes by morphology and length differences. Trichoid sensilla are confined to the last 2 flagellum segments on both sexes. Sexual dimorphism of antennal sensilla is limited to the three types of difference. The principal characteristics of this dimorphism are the following: a) The distribution of sensilla was differ from male and female in antennae. b) Males exhibit coeloconic sensilla not present in females; c) Females posses more trichoid sensilla than males. The possible role of specific dilference of the sensilla in intersexual communication is discussed.
