The basic product of export of Cuba were, for that moment, pork and a sugar cane. As a result of application БО on Cuba all livestock of pigs and up to 80 % of landings of a sugar cane was lost.
Application БО has been carried out, possibly, at airport Varadero, whence (probably near to a gangway of self-summer) the mosquitoes infected by the activator hem. con. of pigs have been let out.
