Bactrocera zonata (peach fruit fly) is an A1 pest for EPPO and is regulated by many EPPO member countries (often as Dacus zonatus). Details of its biology, distribution and economic importance can be found in EPPO/CABI (1997).
Bactrocera zonata originates from South and South-East Asia (India, Indonesia, Laos, Sri Lanka, Thailand, Vietnam) and has been introduced into Bangladesh, Myanmar, Nepal, Pakistan, Saudi Arabia, Oman, Mauritius and Reunion Island. It is now present throughout Egypt, up to the borders of the Palestinian Territories (Gaza Strip) and Israel. Its presence has also been recorded recently in southern Iran and Lebanon. Experience in Egypt shows that B. zonata has already adapted to climatic conditions different to those in its area of origin. This major economic pest presents a threat to countries in West Asia, but also in North Africa and in Southern Europe.
The main hosts of B. zonata are guava, mango and peach. Secondary hosts include apricot, fig and citrus. This fly has been recorded on over 50 cultivated and wild plant species, mainly those with fleshy fruits. A list of susceptible species is given in Appendix 1. Eggs are laid inside the fruit and larvae feed on the fruit. Transport of infested fruit, either through trade or by travellers, is the main means of movement, and the pest will also spread via fruit packaging material. Its natural means of spread is adult flight.
EPPO member countries with areas at risk are advised to prepare a contingency plan for surveillance, eradication and containment of B. zonata.
This standard presents the basis of a national regulatory control system for the eradication and containment of B. zonata and includes guidance on its surveillance.
Countries where B. zonata is not capable of establishment due to climatic, geographical or other reasons, and where absence is recognized according to the first paragraph of section 3.1.2 of International Standard for Phytosanitary Measures (ISPM) No. 8 (Determination of pest status in an area), may decide that they have no reasons to apply the standard.
The EPPO countries bordering areas of known infestation are at highest risk and are advised to prepare a contingency plan for surveillance and eradication. Attention should be paid to providing sufficient traps, and registering suitable plant protection products for emergency treatments. Facilities should be identified which are suitable for disposal of contaminated wastes, destruction of woody plants and treatment of harvested fruits to ensure freedom from pests. Field inspection staff, including non-permanent workers, should be trained. Laboratories should have specimens of adults, larvae and pupae available and staff suitably trained in determining B. zonata.
This standard has been prepared on the basis of the Peach Fruit Fly Action Plan (FAO/IAEA, 2000), the NAPPO Regional Standards for Phytosanitary Measures No. 10 (NAPPO, 1998) and ISPM No. 26 Establishment of pest free areas for fruit flies (Tephritidae) (IPPC, 2006c).
