Unlike humans, the sex and physical appearance of fruit flies is not influenced by hormones. [16] The appearance and sex of fruit flies is determined only by genetic information. [16] Female fruit flies are substantially larger than male fruit flies, with females having bodies that are up to 30% larger than an adult male. [17] [18]
Drosophila is a prime candidate for genetic research because the relationship between human and fruit fly genes is very close; disease-producing genes in humans can be linked to those in Drosophila. [52] The fly has approximately 15,500 genes on its four chromosomes, whereas humans have about 22,000 genes among their 23 chromosomes. [53]
The Drosophilidae are a diverse, cosmopolitan family of flies, which includes species called fruit flies, although they are more accurately referred to as vinegar or pomace flies. [1] Another distantly related family of flies, Tephritidae , are true fruit flies because they are frugivorous, and include apple maggot flies and many pests.
Drosophila melanogaster, the common fruit fly, has been used to study the effects of spaceflight on living organisms.. On a July 9, 1946, suborbital V-2 rocket flight, fruit flies became the first living organisms to go to space, and on February 20, 1947, fruit flies safely returned from a suborbital space flight, which paved the way for human exploration.
Anastrepha obliqua is a species of fruit fly. It is the most important fruit fly pest of mangoes in Neotropics and attacks a wide range of other spicy fruits. A. obliqua is widespread in Mexico, Central and South America and the West Indies. [1] It is sometimes called the West Indian fruit fly in English.

Drosophila montana, colloquially referred to as a fruit fly, [1] is a species of fly belonging to the family Drosophilidae and the genus Drosophila. [1] [2] It belongs to the montana phylad, which diverged from the D. virilis species group in South Asia before its migration into North America. [3]
Lake Malawi Museum is a museum on Lake Malawi in Malawi.Situated in the Old Gymkhana Club and organized by the Society of Malawi since 1971 [1] (and likely not updated since then), the museum is located near the Queen Victoria memorial near the Bakili Muluzi Bridge in Mangochi town, Mangochi District, within the Southern Region of Malawi.
