tephritids

Tephritids, or tephritid flies, form the family Tephritidae within the order Diptera. They are among the fruit flies most familiar to agriculture and natural ecosystems, and they are distinguished by often vividly patterned wings that serve species recognition. Adults typically range from about 2 to 10 mm in length, with wing markings varying widely among species. The family is large and diverse, comprising thousands of described species found in tropical, subtropical, and temperate regions worldwide, with particularly high diversity in the Americas, Africa, and parts of Asia.

Ecology and life history: Tephritid larvae are primarily phytophagous, developing as internal feeders in plant tissues. Many species oviposit in fruits, seeds, stems, or flower heads, and the hatched larvae feed inside the host before pupating in soil or plant debris. Host ranges span from highly specialized to broad, and larvae can cause direct damage to crops as well as secondary infections by pathogens. Adults feed on nectar, honeydew, and often overripe fruit. Mating behavior is varied and frequently involves visual displays and species-specific pheromones or courtship rituals.

Economic and ecological significance: Tephritids include some of the world's most impactful agricultural pests, such as Ceratitis capitata (Mediterranean fruit fly), Bactrocera dorsalis (oriental fruit fly), and Bactrocera oleae (olive fruit fly). They are targets of quarantine and pest management programs due to their potential to infest fresh fruit and nuts. Conversely, research on tephritids has contributed to biological control methods and sterile insect technique programs.

Management: control strategies emphasize monitoring and rapid detection, cultural practices, biological control, sterile insect technique, and, when necessary, targeted chemical measures, all integrated within broader pest management frameworks.
