Bactrocera carambolae

[2] From DNA analyses it was determined that B. carambolae forms a reciprocally monophyletic sister group to a larger clade containing the B. dorsalis species complex.

[7] Compared to other members of the B. dorsalis complex, B. carambolae have shorter male reproductive organs, known as aedeagi, and broader costal bands on their wings.

[7] Bactrocera carambolae are a polyphagous species which infects over 100 different host plants, including avocado, guava, mango, papaya and orange, among several others.

[5][8] The adult female B. carambolae lays her eggs under the skin of host fruits, which take a maximum of two days to hatch.

Following seven to ten days, the fruit matures and falls to the ground below, where the larvae pupates into the soil; emerging approximately one week later.

[9] The adult flies take approximately three weeks to fully mature, making the full life cycle last roughly 35 days.

[10] The large abundance of Proteobacteria are essential in the act of courtship and reproduction of not only B. carambolae, but Bactrocera fruit flies in general.

They are stored in the male rectal gland, and when released into the air they create upwind flight via zigzag movement, attracting a significant number of female B. carambolae for courtship.

The gecko is an avid consumer of immature carambola larvae, however their consumption greatly decreases when it comes to sexually mature male B.

[1] The economic losses through invasions by the carambola fruit fly, and those alike, raise a major concern for farmers and government agencies.

[5] B. carambolae are attracted to the scent of ammonia present in the insecticide, therefore it can be applied to only a small amount of spots in a crop and remain effective.
