Temperature and relative humidity mediated life processes of species (Lepidoptera: Noctuidae).

Anthropogenic-mediated climate change is expected to negatively affect pest management in agriculture. Hence, we investigated the oviposition, immature mortality, and developmental processes of species ( (Hübner) and (Fabricius)) under different temperatures (20, 25, and 30°C) and relative humidity (RH) (30-35, 50-55, 70-75, and 90-95%) conditions. For fecundity, mouths of each species were released into a rectangular box whose inner walls were covered with a sheet of white paper for each combination of temperature and RH.

Temperature and Host Plant Impacts on the Development of (Fabricius) (Lepidoptera: Noctuidae): Linear and Nonlinear Modeling.

The tobacco cutworm, (Fabricius) (Lepidoptera: Noctuidae), is one of the most serious pests in field crops, vegetables, and ornamentals. Temperatures (15, 20, 25, 27, 30, 35, and 40 °C), host plants (soybean ( (L.)), maize ( L.

First report of of sword bean in South Korea.

(SMV) is a member of the genus in the family . Legume crops are often infected by SMV. SMV has not been naturally isolated from sword bean () in South Korea.

Evaluation of Soybean Wildfire Prediction via Hyperspectral Imaging.

Plant diseases that affect crop production and productivity harm both crop quality and quantity. To minimize loss due to disease, early detection is a prerequisite. Recently, different technologies have been developed for plant disease detection.

First report of post-harvest tuber rot of Medikus caused by in South Korea.

Medikus, a perennial vine legume native to North America, is known as 'Indian potato' or 'Apios' for their underground tubers that are used for human consumption in Korea (Choi et al., 2017). These tubers are known to be rich in isoflavones as well as other secondary products to have known several medicinal properties (Chu et al.

Utilization of Spectral Indices for High-Throughput Phenotyping.

The conventional plant breeding evaluation of large sets of plant phenotypes with precision and speed is very challenging. Thus, consistent, automated, multifaceted, and high-throughput phenotyping (HTP) technologies are becoming increasingly significant as tools to aid conventional breeding programs to develop genetically improved crops. With rapid technological advancement, various vegetation indices (VIs) have been developed.

First Report of causing Fusarium wilt on in South Korea.

Soybean ( L.) is one of the most important crops worldwide. In South Korea, three species of have been reported as causal pathogens of Fusarium wilt of soybean (KSPP, 2021).

Species Composition, Abundance, and Seasonal Dynamics of Perilla Seed Bugs (Heteroptera: Lygaeidae) in Weeds and Perilla Fields in Korea.

Perilla seed bugs (Nysius sp.) are considered to be the emerging pests causing nutritional and yield losses in perilla and cereal crops. A survey of perilla seed bugs on weeds and perilla crops was conducted over the course of 2 yr in Korea to determine the species composition, abundance, and seasonal dynamics of perilla seed bugs.

First Report of causing Anthracnose on in South Korea.

Sorghum ( (L.) Moench) is one of the top five cereal crops in the world, but the cultivation area in Korea is estimated to be about 3,000 ha (MIFFAF, 2012). In August 2014, anthracnose symptoms on sorghum leaves were observed in two fields in Yecheon (36.

Complete genome sequence of peanut virus C, a putative novel ilarvirus.

We determined the complete genome sequence of a putative novel ilarvirus, tentatively named "peanut virus C" (PVC), identified in peanut (Arachis hypogaea). The three segmented genomic RNA molecules of PVC were 3474 (RNA1), 2925 (RNA2), and 2160 (RNA3) nucleotides in length, with five predicted open reading frames containing conserved domains and motifs that are typical features of ilarviruses. The three genomic RNAs shared nucleotide sequence similarity (74% identity and 93% query coverage for RNA1, 75% identity and 85% query coverage for RNA2, and 72% identity and 70% query coverage for RNA3) with the most closely related ilarvirus, parietaria mottle virus.

First Complete Genome Sequence of Barley Virus G Identified from Proso Millet () in South Korea.

The complete genome sequence of an Uiseong isolate of barley virus G (BVG) on proso millet plants in a field in South Korea was determined by RNA sequencing and Sanger sequencing. To our knowledge, this is the first complete genome sequence report of BVG infecting proso millet in South Korea.

Complete Genome Sequences of Grapevine Yellow Speckle Viroid 1 and Hop Stunt Viroid Assembled from the Transcriptome of Ixeridium dentatum Plants.

Here, we report complete genome sequences of grapevine yellow speckle viroid 1 (GYSVd1) and hop stunt viroid (HSVd), members of the family Pospiviroidae, assembled from the transcriptome data generated from Ixeridium dentatum plants. To our knowledge, this is the first report of GYSVd1 and HSVd in I. dentatum.

One-step multiplex reverse transcription-polymerase chain reaction for the simultaneous detection of three rice viruses.

Rice stripe virus (RSV), Rice black-streaked dwarf virus (RBSDV), and Rice dwarf virus (RDV) are major rice-infecting viruses in Korea that can cause serious crop losses. A one-step multiplex reverse transcription-polymerase chain reaction (mRT-PCR) was developed for the simultaneous detection of these rice viruses. Three sets of specific primers targeted to the capsid protein coding genes of RSV, RBSDV, and RDV were used to amplify fragments that were 703 bp, 485 bp, and 252 bp, respectively.

Hybrid treatment for thoracic aortic aneurysm combined with aberrant right subclavian artery.

An aberrant right subclavian artery (ARSA) is the most common vascular abnormality of the aortic arch and is associated with development of aneurysms in 3-8% of these anomalies. In this case report, we describe an 84-year-old man with a symptomatic ARSA treated with staged hybrid procedure combining surgical replacement of the ascending aorta and bilateral carotid-to-subclavian artery bypass with implantation of a stent graft in the aortic arch and descending aorta. Our case suggests that a less invasive hybrid therapy can be performed successfully for the treatment of ARSA with aneurysmal change in patients at high surgical risk.

The Effect of Seed-borne Mycoflora from Sorghum and Foxtail Millet Seeds on Germination and Disease Transmission.

The seed-borne mycoflora of sorghum and foxtail millet collected from different growing areas in South Korea were isolated and taxonomically identified using dry inspection, standard blotter and the agar plate method. We investigated the in vitro and in vivo germination rates of disinfected and non-disinfected seeds of sorghum and foxtail millet using sterilized and unsterilized soil. The percent recovery of seed-borne mycoflora from the seed components of sorghum and foxtail millet seeds was determined and an infection experiment using the dominant species was evaluated for seedling emergence and mortality.
