The '''pitaya''' (also known as '''pitahaya''', '''dragon fruit''', '''huǒ lóng guǒ''' (火龍果/火龙果), '''strawberry pear''', '''nanettikafruit''', or '''thanh long''') is the [[fruit]] of several [[cactus]] [[species]], especially of the [[genus]] ''[[Hylocereus]]'', but also see ''[[Stenocereus]]''. Native to [[Mexico]] and [[Central America|Central]] and [[South America]], these vine-like [[epiphyte|epiphytic]] cacti are also cultivated in [[Southeast Asia]]n countries such as [[Vietnam]], the [[Philippines]], and [[Malaysia]]. They are also found in [[Taiwan]], [[Okinawa]], [[Israel]], and southern [[China]]. The pitaya blooms only at night; they are large white fragrant flowers, typical of cactus, that are often called [[Moonflower]] or Queen of the Night.

The species ''[[Stenocereus]] gummosus''<ref>{{cite web | url=http://www.oceanoasis.org/fieldguide/sten-gum.html| title = Ocean Oasis Field Guide| accessdate = 2007-10-01}} </ref> in the [[Sonoran Desert]] has been an important food source for Native American peoples. The [[Seri people]] of northwestern Mexico still harvest the highly appreciated fruit of the ''pitaya agria'' (Spanish), which the Seris call ''ziix is ccapxl'' - "thing whose fruit is sour".

==Cultivation==

The plant has adapted to live in dry tropical climates with a moderate amount of rain.
The dragonfruit sets on the cactus-like tree 30-50 days after flowering and can sometimes have 5-6 cycles of harvests per year. There are some farms in Vietnam that produce 30 tons of fruit per hectare every year. <ref>{{cite web | url=http://www.newcrops.uq.edu.au/newslett/ncn11163.htm| title = Pitaya (Hylocereus undatus), a Potential New Crop for Australia| accessdate = 2007-09-14}} </ref>

==Pests, diseases and problems==

Overwatering or excessive rainfall can cause the flowers to drop and fruit to rot. Birds can be a nuisance. There is a [[bacterium]] named ''[[Xanthomonas campestris]]'', which causes the stem flesh to rot. The fungus ''[[Dothiorella]]'' can cause brown spots on the fruit, but is not common.

==Fruit==
[[Image:Dragon_fruit.JPG|thumb|right|Dragon fruit]]
The fruit comes in three types, all with leathery, slightly leafy skin:
*''[[Hylocereus undatus]]'', white flesh with pink skin
*''[[Hylocereus costaricensis|Hylocereus polyrhizus]]'', red flesh with pink skin
*''[[Selenicereus megalanthus]]'', white flesh with yellow skin

The fruit can weigh from 150-600 grams and the flesh, which is eaten raw, is mildly sweet and low in [[calorie]]s. Eating the fruit is sometimes likened to that of the [[kiwifruit]] due to a prevalence of [[sesame]] seed-sized black crunchy seeds found in the flesh of both fruits which make for a similar texture upon consumption. The skin is not eaten. The fruit may be converted into [[juice]] or [[wine]]; the [[flower]]s can be eaten or steeped as [[tea]]. Although the tiny pitaya seeds are eaten with the flesh, the seeds are indigestible. It is generally recommended that dragon fruit be eaten chilled, for improved flavor.
