Theobroma cacao by bees (Hymenoptera) or butterflies/moths (Lepidoptera), cacao flowers are pollinated by tiny flies, "Forcipomyia" midges in the subfamily Forcipomyiinae. Having the natural pollinator "Forcipomyia" midges for "Theobroma cacao" was shown to have more fruit production than using artificial pollinators. The fruit, called a cacao pod, is ovoid, long and wide, ripening yellow to orange, and weighs about when ripe. The pod contains 20 to 60 seeds, usually called "beans", embedded in a white pulp. The seeds are the main ingredient of chocolate, while the pulp is used in some countries to prepare refreshing juice, smoothies, jelly, and nata. Usually discarded
Theobroma cacao up to 8% of cacao pods dry weight. The cacao genome appears close to the hypothetical hexaploid ancestor of all dicotyledonous plants, and it is proposed as an evolutionary mechanism by which the 21 chromosomes of the dicots' hypothetical hexaploid ancestor underwent major fusions leading to cacao's 10 chromosome pairs. The genome sequence enables cacao molecular biology and breeding for elite varieties through marker-assisted selection, in particular for genetic resistance to fungal, oomycete and viral diseases responsible for huge yield losses each year. In 2017-18, due to concerns about survivability of cacao plants in an era of global warming in
