Natal Fruit Fly

Ceratitis rosa, Natal fruit fly

Ceratitis rosa or natal fruit fly is a polyphagous African species.

It has been introduced to the Mascarene Islands: Mauritius and Réunion. It is considered to be a major pest of a number of commercial fruits, including fruits that are grown in subtropical or more temperate environments. It has similar environmental requirements to Ceratitis capitata except that it can withstand less dry conditions, but it is probably more suited to wetter and/or colder conditions. It should be considered as a potential invasive species in other parts of Africa, outside its current range, and in other parts of the world. The most likely pathway of dispersal and introduction is as larvae in infested fruits with commercial shipments or in the luggage of travellers. Ceratitis rosa is of quarantine significance for EPPO, JUNAC and OIRSA.

Ceratitis rosa, like other Ceratitis spp., has banded wings and a swollen scutellum which is marked yellow and black. The pattern of grey flecks in the basal wing cells distinguishes Ceratitis spp. from most other genera of tephritids. The Natal fruit fly overwinters in the adult stage and is able to withstand temperatures as low as 20°F, provided the warming period comes slowly. Food, water, and shelter are more important overwintering factors than temperature. Overwintering flies feed on honeydew and require an abundant water supply. This species is not attracted to traps during the winter months. Eggs are laid 10 to 20 at a time just below the fruit surface. Eggs may be laid in unblemished fruit and in ripe or unripe fruit. Eggs usually hatch within four days after oviposition, but may require longer than four days during cold weather. The three larval stages and a prepupal stage occupy a period of about 12 days. Pupation takes place in the soil, and the pupal stage lasts 10 to 20 days. Females usually begin oviposition in about seven days. Adults may live for several months.

Research & Development

Trap application guidelines

Do not re-use the trap to monitor different insects as this may lead to mixed catches. One-two hundred traps for every hectare of large scale fields of homogenous lands.

Lures for pest monitoring


Lures can be changed every 4-6 weeks to get the most accurate results.

Lures handling

Pheromone lures are a very sensitive tool. They can be affected by exposure to elevated heat and direct sunshine. Direct touching by hand may cause cross contamination leading to mixed catches in the trap. Some contaminants such as Nicotine May have repellent effect reducing trap catch.

Lure Storage

Store in a cool dry place.

Shelf life can vary from 3-36 months depending on the storage temperature.
