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.

ABSTRACT Collections of mosquitoes were conducted for the surveillance of species of medical importance in the state of Morelos, Mexico, in June 2017. Species collected included Mansonia (Mansonia) dyari, which was identified using morphological characters and cytochrome c oxidase I DNA barcoding. Although 3 species of genus Mansonia have been previously reported in Mexico, this is the 1st confirmed record of Ma. dyari in Morelos State, where no Mansonia species had been recorded. Historical records of Ma. dyari and Ma. indubitans in Mexico were reviewed. Therefore, this record increases the number of mosquito species occurring in Morelos to 46. The specimens collected in this study were deposited in the Culicidae collection of the Universidad Autónoma Agraria Antonio Narro, Unidad Laguna.

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.
