Invasion and spread of the neotropical leafhopper (Hemiptera: Cicadellidae) in Africa and North America and the role of high-altitude windborne migration in invasive insects.

Invasive insects threaten ecosystem stability, public health, and food security. Documenting newly invasive species and understanding how they reach into new territories, establish populations, and interact with other species remain vitally important. Here, we report on the invasion of the South American leafhopper, into Africa, where it has established populations in Ghana, encroaching inland at least 350 km off the coast.

Baseline susceptibility of Anopheles gambiae to clothianidin in northern Ghana.

Background: Clothianidin, an insecticide with a novel mode of action, has been deployed in the annual indoor residual spraying programme in northern Ghana since March 2021. To inform pragmatic management strategies and guide future studies, baseline data on local Anopheles gambiae sensu lato (s.l.
