This study focuses on morphological and genetic differences between two central European subspecies of the noctuid moth Noctua interjecta Hübner: N. interjecta interjecta Hübner, 1803 from Transcarpathia in Ukraine and N. interjecta caliginosa (Schawerda, 1919) from Poland. While the morphological differences between these taxa are fairly obvious, individuals from these two populations were found to differ also genetically, as indicated by the cytochrome c oxidase I (COI) gene sequences. The Transcarpathian population exhibits solely the NImizH3 haplotype, but the Polish one the relatively distant NImizH1 and NImizH2 haplotypes. A Neighbour-Joining tree and a network of haplotypes separated the two haplotypes found in Poland (N. i. caliginosa) from those derived from NImizH3 (N. i. interjecta). The divergence time for these two groups was estimated as 400–600 thousand years before present, coinciding with the maximum extent of the Pleistocene ice-sheet covering Europe.

We submitted first results of the DNA studies of the Central Asiatic owlet moths of the genus Euchalcia. Standard cytochrome C oxidase subunit I (COI) gene fragments were sequenced for DNA barcoding of six specimens belonging to Euchalcia herrichi and Euchalcia gyulai. We compared the received sequences between discussed species and with two European Euchalcia species (E. variabilis and E. consona). We found no variability within the COI sequences of the samples collected in the same locality (Alai Mts., Kyrgyzstan), whereas the difference in COI sequences between two populations (Ketmen Mts., Kazakhstan and Alai Mts., Kyrgyzstan) was 0.005.

AbstractThe fall armyworm (FAW), an invasive pest of maize, is an emerging threat in Southern Asia after America and Europe. Recently, this notorious pest has also been found in different areas of Pakistan. To assess its presence in Pakistan, a survey was carried out in the provinces of Punjab, Sindh, and Khyber Pakhtunkhwa during May–October 2019. We observed the highest incidence of FAW in Sindh with maximum impact in districts Tando-Allahyar and Hyderabad. These samples were identified as Spodoptera frugiperda on the morphological and taxonomical bases. However, morphological identification of this pest is very difficult at early larval instars. Here, we use the mitochondrial cytochrome c oxidase I (COI) gene region for the precise identification of larva of this invasive pest at species level. Two different regions of COI gene (COI-5′ and COI-3′) were used as molecular markers for the identification of this species. DNA sequence similarity searches of the obtained COI gene sequences (NCBI GenBank Accession Nos. MW241537, MW241538, MW349515, MW349516, MW349493 and MW349494) revealed that genetically it is more than 99% identical to S. frugiperda. The phylogenetic analysis indicated it as the rice-strain (R-strain). Both 3′- and 5′-fragment tree topologies showed that the collected samples of the FAW species belong to the R-strain. To the best of our knowledge, this is the first report providing molecular evidence for the existence of R-strain of S. frugiperda that was found feeding on maize crop in Sindh, Pakistan, using COI gene sequences as a marker.

Daerah Modoinding dan Tomohon di Sulawesi Utara, dikenal sebagai  daerah penghasil sayuran kubis di Indonesia. Sayuran kubis memiliki hama utama yaitu Plutella xylostella. Penyebab serangga ini dapat bertahan hingga saat ini karena adanya sifat resistensi akibat pemberian insektisida yang berlebihan. Penelitian ini dilakukan untuk menganalisis variasi pada gen cytochrome C oxidase IPlutella xylostella yang diperoleh dari dua lokasi yang berbeda, yaitu Modoinding dan Tomohon. Analisis sekuens menunjukkan adanya perbedaan pasang basa nukleotida dari sampel yang berbeda lokasi. Selain itu, variasi juga ditunjukkan pada sampel yang diperoleh dari basis data GenBank dengan adanya perbedaan 1-14 pasang basa nukleotida dengan spesimen pada penelitian ini. Hubungan kekerabatan gen COI P. xylostella keseluruhan sampel tergolong dalam variasi intraspesies dengan nilai jarak genetik berkisar antara 0-0,022 (0-2,20%).Modoinding and Tomohon areas in North Sulawesi, are known as regions in Indonesia that produce a cabbage. The main pest of cabbage, Plutella xylostella. This insect can survive due to its resistance resulted from prolonged insecticide application. This study aims to analyze genetic variation of COI genes in P. xylostella from Modoinding and Tomohon areas. Sequence analysis showed there were differences in nucleotide base pairs between these locations. In addition, variations were also shown in samples obtained from the GenBank database with differences in 1-14 nucleotide base pairs with specimens in this study. The genetic relationship of P. xylostella COI gene in all samples was classified as intraspecific variation with genetic distance values ranging from 0-0,022 (0-2,20%).D aerah Modoinding dan Tomohon di Sulawesi Utara, dikenal sebagaidaerah penghasil sayuran kubis di Indonesia.

The frequency of occurrence of abnormal, three- (or more) needle dwarf shoots of most southern and central European two-needle pine (<em>Pinus</em>) species were studied. No specimens with more than two-needle dwarf shoots were found in a population of <em>P. nigra </em>Arnold subsp. <em>salzmannii </em>(Dunal) Franco from the Iberian Peninsula and in two populations of <em>P. uliginosa</em> Neumann from the Sudeten Mountains in Central Europe. Single specimens were found within one population of <em>P. pinaster </em>Aiton from the Iberian Peninsula and among six populations of <em>P. sylvestris </em>L. from the Iberian Peninsula and Central Europe. Abnormal dwarf shoots mostly with three, but also four, five or six needles were found among 24 of 25 surveyed populations of <em>P. mugo </em>Turra and <em>P. uncinata </em>Ramond. The average frequency of specimens with at least one three-needle dwarf shoot was 24% for <em>P. mugo</em> and 20% for <em>P. uncinata</em>. The frequencies of occurrence varied significantly among studied populations and were highest in samples collected from the upper elevational range limits of the species in the mountains and near the northern limits of their ranges. The frequency of abnormal dwarf shoots in the same populations was significantly high in 2-3 consecutive years. Needles from three-needle dwarf shoots were not significantly shorter than those of two-needle shoots.

Abstract The giant mottled eel is a species with high commercial value so overfishing, river management, and water pollution have negatively affected its movement and population numbers. Anguilla marmorata (eel) was listed in the Vietnam Red Data Book 2007 with a description of Vulnerability. This study used a barcode technique to analyze molecular characteristics and build genetic plants based on the cytochrome c oxidase I gene segment isolated from the mitochondrial genome of 48 individuals of A. marmorata collected in five different ecological regions of Thua Thien Hue, Vietnam. The isolated the cytochrome c oxidase I sequence has a length of 843 nucleotides, four base nucleotides of 30.03% Thymine, 25.15% Cytosine, 27.49% Adenine, and 17.43% Guanine. The percentage of Guanine + Cytosine content (42.58%) is acceptable, lower than the Adenine + Thymine content. The replacement capacity of Adenine and Guanine is 22.45% highest, the ratio between Thymine and Guanine; Cytosine and Guanine are the lowest at 2.72%. The establishment of genetically modified plants has shown the high genetic similarity of individuals in eel populations in Thua Thien Hue. The population of Anguilla marmorata eels in Thua Thien Hue, Vietnam is divided into two separate groups that are guided by the migration process and specific ecological. This is particularly important in building strategies to conserve and develop the gene for eel in Vietnam and Thua Thien Hue.
