The cacao bean in 80% of chocolate is made using beans of the Forastero group, the main and most ubiquitous variety being the Amenolado variety, while the arriba variety (such as the Nacional variety) are less commonly found in Forastero produce. Forastero trees are significantly hardier and more disease-resistant than Criollo trees, resulting in cheaper cacao beans. Major cocoa bean processors include Hershey's, Nestlé and Mars, all of which purchase cocoa beans via various sources. Chocolate can be made from "T.
Midge greatly from species to species, though within any particular family, midges commonly have similar ecological roles. One type of midge "ceratopogonid midges" (a type of fly in the family Dipteran) is a major pollinator of "Theobroma cacao" (cocoa tree) because of its unique morphological and behavioral characteristics. Having natural pollinators has beneficial effects in both agricultural and biological production because it increases "Theobroma cacao" crop yield and also density of predators of the midges (still beneficial to all parties). Examples of families that include species of midges include: The Ceratopogonidae (biting midges) include serious blood-sucking pests, feeding both on humans
