Summary: Biting midges of the genus Culicoides Latreille were collected from two BTV prevalent provinces in western Thailand, and identified using wing morphology and molecular markers. The most abundant potential BTV vector species identified were Culicoides peregrinus. These results contribute to new knowledge of Culicoides BTV vectors in Thailand and will aid further BTV studies in the region.

Summary: This study used mitochondrial cytochrome c oxidase I (COI) sequences as genetic markers to evaluate the level of genetic diversity and the genetic structure of Culicoides mahasarakhamense from Thailand. Results showed that the level of genetic diversity was relatively high, but most populations were not genetically different. However, one population from northern Thailand was found to be genetically highly different from others, possibly due to historical population isolation and geographic distance separation.

Summary: Biting midges of the genus Culicoides are potential biological vectors for arbovirus transmission. A study in the border areas of Yunnan Province, China, collected 405 Culicoides individuals from seven animal farms and detected the presence of major arboviruses, with Bluetongue virus 1 being found in Culicoides oxystoma specimens. The study suggests that C. oxystoma species could play a role in the transmission of Bluetongue virus.

Summary: This population genomics study uncovers the complex multiple introduction history of the fall armyworm from the Americas to Africa and Asia, providing insights into the directionality of gene flow and the extent of genomic exchange. The study highlights the potential of international partnership and population genomic approaches in addressing global emerging pest threats and biosecurity challenges. The study also challenges the previous hypothesis of west-to-east spread, instead finding evidence of directional gene flow from the East to eastern Africa.

Summary: This study examined the population genetic structure of the bean leaf beetle in Uganda using microsatellite DNA markers and mitochondrial cytochrome oxidase subunit I gene sequences. The results showed that the genetic variation occurred mainly within populations and there was no evidence of genetic differentiation. There was also no evidence of isolation by distance between geographical and genetic distances, except in one agro-ecological zone. This information will contribute to the design of control strategies for the bean leaf beetle.

Summary: The fall armyworm is a harmful pest present in many countries. Its rapid spread and damage to agriculture pose challenges. Currently, management of this pest relies on insecticides and genetically modified crops. Understanding its response and resistance genes is crucial. In Australia, the pest has been detected and studied, revealing multiple pathways and introductions contradicting previous assumptions of its spread.

Summary: The fall armyworm, a notorious agricultural pest, has rapidly spread from West Africa to East Asia since 2016. Genome analysis revealed that the majority of populations in this study were hybrids of C- and R-strains. The spread of the fall armyworm was facilitated by international trade of live/fresh plants and plant products, as well as the establishment of "bridgehead populations" in neighboring countries.

Summary: The European grapevine moth is a species that can feed on over forty plant species, but grapevine is its preferred crop globally. It has recently spread to Chile, Argentina, and California, and there are concerns about its possible further expansion in other regions of the Americas. In this study, we provide an updated review of its taxonomy, morphology, biology, ecology, genomics, geographic distribution, and invasiveness. We also outline significant challenges for future research on bio-ecology and invasion biology, which are crucial for prevention and management strategies.
