A life stage-targeted acaricide application approach for the control of Haemaphysalis longicornis

Matthew Bickerton et al.

Summary: This study indicates that a single application of pyrethroid acaricide lambda-cyhalothrin can effectively control Haemaphysalis longicornis for up to 7 weeks, with the highest efficacy observed when applied in June and July. A late-summer application in August can also provide near complete control of the larval population. Multiple sequential treatments targeting all life stages can significantly reduce the overall population of H. longicornis throughout its activity season.

A multi-seasonal study investigating the phenology, host and habitat associations, and pathogens of Haemaphysalis longicornis in Virginia, USA

Alec T. Thompson et al.

Summary: The study on the phenology of Haemaphysalis longicornis in Virginia revealed seasonal differences in tick activity compared to previous studies in the northeastern United States. The presence of this exotic tick was found to be lower in field habitats and during the summer months, and it was detected on several wildlife hosts. Additionally, tick-borne pathogens were analyzed, including the detection of arthropod-borne pathogens native to the United States in host-seeking H. longicornis.

Complete mitochondrial genome of Asian longhorned tick, Haemaphysalis longicornis, Neumann, 1901 (Acari: Ixodida: Ixodidae) identified in the United States

Ji-Yeon Hyeon et al.

Summary: Limited knowledge exists about the genetic features of Haemaphysalis longicornis in the US. In this study, the complete mitochondrial genome of two H. longicornis ticks collected in New York in 2020 was sequenced. The mt-genome showed high similarity to those of H. longicornis from China, providing valuable insights for genetic changes and phylogenetic studies of this tick species.
