THE PRESENCE OF WHITEFLIES IN HORTICULTURA AREAS OF THE AZUERO PENINSULA. LOS SANTOS, PANAMA, 1999.
The whiteflies are the insects plagues that more affect the tropical and subtropical horticolas zones of the world. In the American continent are plant pathogeny numerous vectors of virus. Several species and biotypes of whiteflies exist in Central America and the Caribbean area. In order to identify the species and existing of whiteflies biotypes in the Peninsula of Azuero, Panama, between January and April of 1999 were collected adult and immature individuals in diverse crops in 12 localities. This zone is located between 7° 13' and 8° 08' of North latitude and 79° 59' and 80° 59' of West longitude. Eighteen samples were taken from which five specimens by each one were analyzed, using the molecular test RAPD-PCR, with a total of 90 individuals. The immature stages were identified by means of taxonomic keys. In all the samples Bemisia tabaci was identified. The analysis of RAPD-PCR revealed 12 individuals of biotype A, 61 of biotype B and 17 without identifying, due to operative errors or differences in the electrophoretic pattern of the previous biotypes. The biotype A was identified in aji (Capsicum annum), tomatoe (Lycopersicon esculentum) and melon (Cucumis melo) in three localities. The biotype B was in the previous crops and zapallo (Cucurbita pepo) in all the localities. The biotype predominated in most of the samples.
