Dual-Donor-Induced Crystallinity Modulation Enables 19.23% Efficiency Organic Solar Cells.

Trap-assisted charge recombination is one of the primary limitations of restricting the performance of organic solar cells. However, effectively reducing the presence of traps in the photoactive layer remains challenging. Herein, wide bandgap polymer donor PTzBI-dF is demonstrated as an effective modulator for enhancing the crystallinity of the bulk heterojunction active layers composed of D18 derivatives blended with Y6, leading to dense and ordered molecular packings, and thus, improves photoluminescence quenching properties.

Chromosome-level genome assembly and comparative genomics shed light on Helicoverpa assulta ecology and pest management.

Background: The Oriental tobacco budworm, Helicoverpa assulta, a specialist herbivorous insect that exclusively feeds on plants of the Solanaceae family, causes considerable damage to crops, such as tobacco and hot pepper. The absence of a genome sequence for this species hinders further research on its pest management and ecological adaptation.

Results: Here, we present a high-quality chromosome-level genome of a Korean strain of H.

Exaptation of I4760M mutation in ryanodine receptor of Spodoptera exigua (Lepidoptera: Noctuidae): Lessons from museum and field samples.

Since 2007, diamide insecticides have been widely used in Korea to control various types of lepidopteran pests including Spodoptera exigua. For nearly a decade, diamide resistance in field populations of S. exigua across 18 localities has been monitored using bioassays.

(Lepidoptera: Noctuidae) Life Table Comparisons and Gut Microbiome Analysis Reared on Corn Varieties.

The fall armyworm (, FAW) is an invasive migratory pest that has recently spread to Korea, damaging several corn cultivars with significant economic value. Comparisons of the growth stages of FAW were conducted based on the preferred feed. Therefore, we selected six maize cultivars, including three categories: (i) commercial waxy corn (mibaek 2-ho, heukjeom 2-ho, dreamoak); (ii) popcorn (oryun popcorn, oryun 2-ho); and (iii) processing corn (miheukchal).

Genetic Diversity of Dengue Vector Collected from South Korea, Japan, and Laos.

is native to Southeast Asia and has emerged as a major vector for vector-borne diseases that are spreading rapidly worldwide. Recent studies have shown that populations have different genetic groups dependent on their thermal adaptations; however, studies on Korean populations are limited. In this study, we analyzed the genetic diversity and structure of two mitochondrial genes ( and ) and sixteen microsatellites in mosquitoes inhabiting Korea, Japan, and Laos.

Comparative population genetics of the invasive mosquito Aedes albopictus and the native mosquito Aedes flavopictus in the Korean peninsula.

Background: Aedes mosquitoes are important invasive species contributing to the spread of chikungunya, dengue fever, yellow fever, zika virus, and other dangerous vector-borne diseases. Aedes albopictus is native to southeast Asia, with rapid expansion due to human activity, showing a wide distribution in the Korean peninsula. Aedes flavopictus is considered to be native to East Asia, with a broad distribution in the region, including the Korean peninsula.

Complete mitochondrial genome of (Yamada, 1921) (Diptera: Culicidae) collected in South Korea.

In this study, we determined for the first time the mitochondrial genome sequence of an specimen collected in South Korea. Its mitochondrial genome was 16,060 bp in length, consisting of 13 protein-coding, 22 tRNA, and 2 rRNA genes and a non-coding A + T rich region. The overall base composition in the heavy strand was 39.

Complete mitochondrial genome of Ortmann, 1894 (Crustacea: Decapoda: Grapsoidea) specimen collected in South Korea.

In this study, the complete 16,184 bp mitochondrial genome of was determined from a specimen collected in South Korea. It consists of 13 protein-coding, 22 tRNA, 2 rRNA genes, and a non-coding A + T rich region. The base composition of the heavy strand in the mitochondrial genome was 34.

Complete mitochondrial genome of the mantis shrimp, Hwang, Ahyong, & Kim, 2018 (Stomatopoda: Protosquillidae).

In this study, we determined the mitochondrial genome of a stomatopod, , collected from Korean waters. The complete mitochondrial genome comprised 15,880 bp, encoding 13 proteins, 22 transfer RNAs, 2 ribosomal RNAs genes, and a non-coding A + T rich region. The overall base composition in the heavy strand was A: 35.

Complete mitochondrial genome of the mantis shrimp (Fukuda, 1909) (Stomatopoda: Gonodactyloidea: Takuidae) in South Korea.

The superfamily Gonodactyloidea is polyphyletic because of Hemisquillidae, but to date, mitochondrial genome of that family does not exist. As valuable data that can be compared in the future with that family within this superfamily, we report the first complete mitochondrial genome sequence of of the family Takuidae. The mitochondrial genome is 15,960 bp in length and consists of 13 protein-coding genes (PCGs), 22 transfer genes, 2 ribosomal genes, and a non-coding A + T rich region.

Phylogeographic studies on two shore crab species from East Asia: similar but different stories.

Background: The genetic structure of marine organisms in the East Asian region has long been a subject of interest. Two grapsid crab species, Hemigrapsus penicillatus (De Haan, 1835) and Hemigrapsus sanguineus (De Haan, 1835), are commonly found in the rocky intertidal zones around this region. They are known to spread via larval migration, which makes them an appropriate model species for observing the genetic structure of East Asian intertidal invertebrate animals.
