Cantharophily (beetle pollination) and Mellithophily (bee pollination) are accepted as possible pollination syndromes in cupuassu (Venturieri et al. 1997, Venturieri 1994). Regarding the two potential pollinators so far identified, the chrysomelid weevils may shelter in cupuassu flowers overnight, feed on pollen in the petal pouches, and then move on the following day when the flower wilts (Venturieri et al . 1997).

The Cupuassu is a plant native to the Amazon, found widely in the wild, when it can live to 80 years and reach more than 30m high. In the north, this vegetable is multiplied by grafting, budding or grafting and by seeds. Cupuassu (Theobroma grandiflorum [Willd. ex Spreng.] Schum.) is a plant that is native to the Amazon and of great importance to family farmers in northern Brazil (Alves et al. 2007). In general, cupuassu plantations have low productivity due to the unselected planting material employed, with high hybridized (Alves et al., 2017) by using the cupuassu controlled-pollination technique, as reported by Venturieri & Ribeiro Filho (1995). After evaluating and selecting the progenies, the most productive parents, who remained asymptomatic for M. perniciosa after 15 years of field exposure, were duly identified and selected.

While individual stem yields of over 80 kg/yr. have been recorded, plantation yields have been frustrated by uneven bearing and tremendous fruit drop caused by poor pollination, drought, nutrient deficiencies, and principally pests and diseases. Flower. Flowers of cupuaçu are structurally complex, and require pollination from biotic vectors. The majority of cupuaçu trees are self-incompatible, which can result in decreased pollination levels, and consequently, a decrease in fruit yields.

Cupuassu (Theobroma grandiflorum) Pollination is carried out mainly by ants and aphids, with vespertine anthesis. The fruit occurs in the form of a drupe and is strong and pleasant smelling. It is smooth on the outside, ellipsoidal, 25 cm long by 12 cm wide and weighs up to 1.5 kg.

Cupuassu (Theobroma grandiflorum), a specie native to Amazonia, has been planted commercially in Brazil to satisfy the demand for the flavorful juice obtained from the pulp around its seeds. The

It is hardy to zone (UK) 10. The flowers are pollinated by Insects, Wind. Suitable for: medium (loamy) and heavy (clay) soils and prefers well-drained soil. Cantharophily (beetle pollination) and Mellithophily (bee pollination) are accepted as possible pollination syndromes in cupuassu (Venturieri et al. 1997, Venturieri 1994).
