First Record and Demonstration of a Southward Expansion of Aedes albopictus into Orange Walk Town, Belize, Central America1

2013

The first record of Aedes albopictus in northern Belize was made in Orange Walk Town, Orange Walk District, on November 3, 2011. Aedes spp. larvae were collected during a routine Ministry of Health mosquito survey and reared to adults. Upon emergence, a mixed population of Aedes aegypti (35) and Ae. albopictus (11) was observed (aegypti∶albopictus = 3∶1). Subsequent larval and adult surveys in Orange Walk and Corozal District, also in northern Belize, have confirmed the presence of Ae. albopictus, thereby indicating the range expansion and establishment of this nuisance biter and potential disease vector in Belize.
