Summary: This research explores the indirect effects of two insecticides on two different species of ladybirds, highlighting the extended and variable impacts of thiacloprid on the predators at different developmental stages. While reducing the field rate of lambda-cyhalothrin had no practical value for survival, using a lower dose of thiacloprid may enhance the chances of survival for certain developmental stages of the ladybirds. The study also found that the adult stages of the two species had similar survival dynamics, with noticeable differences in response to thiacloprid dose rate observed in the L4 stage.

Summary: This study identified differentially expressed genes associated with thiamethoxam resistance in the seven-spot ladybird beetle through transcriptome sequencing. Up-regulation of certain metabolic enzymes and transport proteins, as well as down-regulation of nicotinic acetylcholine receptor gene, were observed in the resistant strain.

Summary: This study evaluates the vulnerability of multicoloured Asian ladybeetle at different stages to both indigenous and invasive predators. The results show that the eggs and larvae of the ladybeetle are susceptible to predation by both native and invasive predators, but less vulnerable compared to other beetle species. The vulnerability of the ladybeetle to predators decreases with the age of the larvae and the weight difference between predator and prey.

Summary: This study used partial sequences of the coi gene to identify Biomphalaria species in Brazil and analyzed them using phylogenetic reconstruction and species delimitation algorithms. The study found that the use of the coi gene could provide insight into the evolution and dispersion of species in the genus, but it is not sufficient for solving complex taxonomic problems within the genus.

Summary: This study used DNA barcoding to survey the insect diversity in Pakistan and found that the knowledge about insect species in Pakistan is limited. Most species can only be classified into order and family, with only a small portion classified into genus and species. The study also found that a majority of the insect species in Pakistan are unique to the country, but some species are also reported in neighboring countries.

Summary: This study conducted DNA sequencing of lacewings and snake flies in Portugal for the first time, revealing that most species can be successfully identified through DNA barcoding, except for seven species of the Chrysopidae family. Additionally, distribution data for two neuropteran species in Portugal were published for the first time.

Summary: One-third of shark and ray species are threatened due to overfishing, and a study conducted in Malaysian waters used DNA barcoding to identify different species, improving species-specific data and aiding in conservation decisions. DNA barcodes for 67 species were successfully generated, belonging to 44 genera, 20 families, and 11 orders. This comprehensive database will facilitate monitoring and assessment of elasmobranch fisheries in Malaysia.

Summary: This study sequenced mitochondrial genes CO-I and Cyt b to elucidate the phylogenetic status of three species of the genus Schizothorax. The results suggest that the simultaneous use of two molecular markers along with morphometric data is a better strategy for the classification of Schizothoracinae species.

Summary: Insect fauna make up the largest proportion of animal biodiversity on earth. However, the assessment and quantification of insect species diversity is still incomplete. Recent studies have shown a rapid decline in insect population. It is crucial to document and quantify the diversity of insect fauna for a better understanding of terrestrial ecosystems. Modern technology, such as DNA barcoding and morphological identification, can be used to identify species more efficiently.

Summary: The fall armyworm is a noctuid moth from the Americas that poses a threat to a wide range of important crops. It consists of two strains with different host plant preferences. While the majority of specimens in Australia belong to the 'rice-strain', there are also 'corn-strain' individuals. Genetic characterization and monitoring of host plant preferences will provide valuable information as the pest spreads to new locations in Australia.

Summary: The yellowstripe scad is an important fish commodity in the Tropical Western Pacific. Genetic studies revealed two geographically distinct lineages of the species, with the Australian lineage potentially being a cryptic species. The species underwent rapid expansion in the late Pleistocene, emphasizing the need for lineage-specific management efforts.

Summary: Background explorations of the Kaladan River in Mizoram, India, have led to the discovery of a new species of torrent catfish. This study uses integrative taxonomy to distinguish the new species from its congeners through morphometric measurements and DNA sequence analysis. The discovery of this new species is significant as it provides insights into the Amblyceps genus in the Kaladan drainage.

Summary: Metabarcoding is a fast-developing field used to determine the species composition and diversity of marine zooplankton communities, but standardization of methods is still incomplete. The choice of genetic markers and primers is crucial for influencing species detection rates and accuracy. Taxon-specific mini-barcode primers have been developed to enhance species detection rates and accuracy in this study.

Summary: The Barcode of Life initiative was motivated by the need to overcome taxonomic difficulties and the limited number of expert taxonomists. This study contributes to the knowledge of DNA barcodes and occurrence records of Colombian freshwater fishes, with new species being identified and genetic diversity being better understood. The deposited specimens and their DNA barcodes are publicly available for further research and the geographical distribution dataset is accessible through the Global Biodiversity Information Facility (GBIF).
