Custard apple, Annona

The pheromones can also be used to enhance a beneficial activity of the beetles. Nitidulids are primary pollinators of custard apple (Annona) flowers, but poor pollination has often been a problem (Gazit et al., 1982 Nagel et al., 1989). A new concept was to place pheromone lures in Annona trees to increase beetle density and enhance pollination, and Pena et al. (1999) found that pollination and fruit set were significantly improved when the pheromones were employed.

Custard Apple, Cherimoya (Annona cherimola, Annonaceae)... 

Reticuline is an important alkaloid, which is remarkably found in Nature in both enantiomeric forms (S)-(+)-reti-culine in Annona reticulata (the fruit is called custard-apple, also bullock s heart or bull s heart), in Phylica roger-sii, and in Papaversom-niferum, while (/ )-(-)-reticu-line occurs in Coulter s Matili-ja poppy (Romneya coulteri var. trichocalyx).

The fruit of a small tree (of the family Annonaceae) that is native to the American tropics. The yellowish-greenheartshaped fruit are 3 to 4 in. (8 to 10 cm) in diameter, white, and have a sweet granular custardlike pulp. They are used as a dessert fruit, and are closely related to the other Annona species of fruit (the most common ones are the cherimoya, custard apple, and soursop). Their flavor is best when fully ripe, a stage at which the fruit is very perishable. 

The heat capacity data of these cheny stones and other fruit seeds (natural micro and nanomaterials), shells and pits, are shown, as a function of temperature, in Figure 12. These include walnut and hazelnut shells, annona (custard apple) fruit seeds, peach pats and olive stones (Queiros, 2010). The plot shows that the heat capacity of all samples increases up to a maximum between 350 and 370 K, decreasing then to very small values (around 1 Jg-iR-i).
