Calonecrinae represent a unique but small subfamily of Nitidulidae that is endemic to South Asia. Their habitats, the South Asian lowland forests, are under the imminent threat of degradation, posing a risk of rapid extinction for these species in their specific locales. Despite the looming threat to their existence, our understanding of this enigmatic group remains limited. We conducted an examination of museum and newly collected specimens, alongside a review of the literature, leading to the discovery of a new species, Calonecrus mindanaoensis, from Mindanao, Philippines. For the first time, the morphology of all immature stages of the Calonecrinae was described, with detailed photographs including SEM images. Additionally, their natural history was uncovered for the first time, revealing that all life stages are uniquely adapted to spending their entire life cycle within sticky resin. We re-evaluated the phylogenetic placement of the Calonecrinae by constructing a phylogenetic tree based on the mitochondrial genome. Calonecrinae are positioned within the Epuraeinae clade and show significant affinity with the genus Trimenus. Consequently, this study proposes reclassifying Calonecrinae as Calonecrini stat nov, an extremely modified tribe within the Epuraeinae.

In this study, the quality of sow pork was compared with commercial pork to evaluate sow pork as raw meat material for processing. Texture, cooking loss, color, pH, water, lipid, fatty acid, volatile profiles, and sensory characteristics of 3 parts (tenderloin, loin, hind leg) of sow and commercial pork were analyzed. In texture analysis, sow pork had significantly higher shear force compared to commercial pork (tenderloin: sow 143.19 N, commercial 107.79 N; loin: sow 173.62 N, commercial 120.65 N; hind leg: sow 211.76 N, commercial 112.80 N) (p<0.05). There were significant differences in cooking loss, color, and pH, but they differed by part. A total of 49 volatile compounds were identified, and there were significant differences in 22 volatile compounds. In the case of hexanal (one of the warmed-over flavors), which was detected on the largest scale, the relative concentration was significantly higher in the tenderloin of commercial pork (p<0.05). On the other hand, no differences were reported by sensory analysis for hardness, off-flavor, juiciness, oiliness, appearance, taste, and acceptability between cooked sow and commercial pork. This study provides a database on the quality of sow pork by parts, which is considerable to develop proceed meat products using sow meat.

Anoplophora horsfieldii (Hope, 1843), 국명 노랑알락하늘소(가칭)는 아열대 지역에 주로 분포하는 종으로 2019 년에 제주도 용연계곡에서 처음 발견되었으며, 2023년에 국내 정착이 보고되었다. 국내에서는 팽나무에서 발생 하는 것으로 알려졌으나, 섭식방식, 산란 선호성 등 생태적 특성에 대해서는 국내외 연구가 전무하다. 따라서 본 연구에서는 노랑알락하늘소의 기초적인 생태정보를 제공하고자 실내 산란 선호성 조사 및 야외조사를 진행 했다. 산란 선호성 실험은 기주식물로 알려진 팽나무, 멀구슬나무와 제주도내 대표 수종인 동백나무, 종가시나무 을 대상으로 했다. 이 중 팽나무에서만 산란이 확인었으며, 상대적으로 굵은 팽나무에서 더 많은 산란이 확인되었 다. 야외조사에서는 최대 발생지인 용연계곡을 기준으로 반경 3 km 내에서 노랑알락하늘소의 탈출공이 확인된 32 그루의 팽나무를 대상으로 피해를 조사하였다. 나무의 굵기는 흉고직경이 20-40 cm인 팽나무에서 탈출공이 많이 확인되었고, 높이는 지면으로 부터 0-100 cm 구간에서 가장 많은 탈출공이 발견되었다.

The Nitidulidae includes 10 subfamilies and over 350 genera and 4500 species and is the largest family in Cucujoidea. We place the enigmatic subfamily Calonecrinae into the internal relationship of Nitidulidae, a comprehensive molecular phylogenetic analysis was performed using five gene regions (COI, 28s, CAD, H3, Wingless) for 80 taxa. We included 73 ingroup taxa representing nine of the ten currently recognized subfamilies of Nitidulidae and 7 outgroups. The phylogenetic results are consistent with prior molecular studies, that include a polyphyletic Nitidulinae with the inclusion of Meligethinae and Cillaeinae and that the Calonecrinae is sister taxon to Epuraeinae. Ancestral state reconstruction of feeding behavior indicates that stem group nitiduilds were most probably sap-feeding with transitions to other feeding types independently derived multiple times.

The genus Rosalia contains three subgenera of which distinctly divided by different body colors and distributional patterns. Eurybatodes is a monotypic subgenus with yellow tegument only found in Yunnan, China. Eurybatus is the most specious subgenus contains 21 species with reddish body color, widely distributed in Oriental region including Taiwan and Ryukyu islands. The blue subgenus Rosalia contains 5 species that distributes West Palaearctic, East Palaeartic, Japan, Oriental and West Nearctic, respectively. Here we present the ongoing research on multi-gene phylogeny and evolutionary studies of the genus Rosalia. This study provides new insight into the internal relationships and the evolutionary history of various traits (e.g. biogeography, colors, elytral patterns) of the genus Rosalia.

Correlated evolution of biology and morphology of related organs of insects is an intriguing yet poorly understood topic. Gigantic member of phytophagan, the subfamily Cerambycinae provide us a unique opportunity to understand the topic because they have wide range of host plants, oviposition strategies and various forms of ovipositors. The evolutionary pathway of these traits is totally unknown because no robust internal phylogeny has been studied. Here we construct a multilocus phylogeny of Cerambycinae (134 taxa, 9 gene regions, 5211bp) focusing on wide range of oviposition strategies, host plant and ovipositor length. Ancestral state reconstruction analyses show that shortened ovipositor in Cerambycinae evolved at least four times independently; host plant use evolved from stressed hosts to dead and living host, broad leaved trees to conifer and herbaceus plants. Continuous mapping of ancestral state reconstruction shows extremely shortened ovipositor evolved independently at least four times. The correlated evolution test revealed the only correlation is between the ovipositor length and the oviposition strategy. This study unveiled the complex evolutionary history of ovipositor, oviposition strategy, host plant usage and their correlation within Cerambycinae for the first time.

Family Nitidulidae is the second largest family in Cucujoidea which includes ten subfamilies. Because of their morphological and biological diversity, the phylogenetic relationship within Nitidulidae is one of the most debated topics among Cucujoidea phylogeny and yet, is still open to many questions. To recover the internal relationship of Nitidulidae, we performed ML and BI analyses that targeted on five gene regions (COI, 28s, CAD, H3, Wingless) for 73 taxa. We include 67 ingroups containing nine of the ten currently recognized subfamilies of Nitidulidae and 6 outgroups. The phylogenetic results suggest followings i) Subfamilial status of Prometopinae is reconfirmed; ii) Epuraeinae is paraphyletic with inclusion of Calonecrinae; iii) Nitidulinae is paraphyletic with inclusion of Meligethinae and Cillaeinae. In addition, the generic relationships within Nitidulinae and the evolutionary history of their feeding behaviors are also briefly discussed.

Evolutionary relationship between ovipositior and oviposition behaviour in insect is an intriguing yet poorly understood topic. Gigantic member of phytophagan, the subfamily Cerambycinae provide us a unique opportunity to understand the topic because they have diversified but specialized host plants, oviposition strategies and ovipositors. The evolutionary pathway of these traits is totally unknown because no robust internal phylogeny of Cerambycinae has been studied. Here we construct a multi-locus phylogeny of Cerambycinae (134 taxa, 9 gene regions, 5211bp) focusing on wide range of oviposition site, host plant and ovipositor length. Ancestral state reconstruction analyses show some general trends in cerambycine evolution: i) host plant use evolved from stressed broad leaved trees to conifers and herbaceus plants; ii) oviposition site evolved from bark crevice to wood fissure or plant surface; iii) extremely shortened and elongated ovipositor independently evolved at least four times, respectively. Correlated evolution test show that ovipositor length and oviposition strategy evolved with very strong correlation, while any of other two traits did. This study unveils the complex evolutionary history of ovipositor, oviposition site, host plant use and their correlation within Cerambycinae for the first time.
