Cydia inopinata (EPPO A2 quarantine pest) occurs in the western part of Henan province, China. Review of Agricultural Entomology, 89(2), p 234 (1718).
Dacus ciliatus (EPPO A1 quarantine pest) was identified on cucurbit crops in Bangladesh. This confirms earlier reports. Review of Agricultural Entomology, 89(5), p 561 (4191).

Frankliniella occidentalis (EPPO A2 quarantine pest) occurs in Auckland, New Zealand (Anonymous, 2001).
In a paper (van den Berg ; Greenland, 2000) reviewing the literature on Tamarixia dryi, a parasitoid of Trioza erytreae (EPPO A1 quarantine pest), it is stated that Liberobacter africanum (causal agent of citrus greening - EPPO A1 quarantine pest) has been a serious problem on St Helena since the 1980s. This statement confirms earlier reports on the possible presence of L. africanum in St Helena.
Liberobacter asiaticum (EPPO A1 quarantine pest – causal agent of citrus greening) was found on pomelos and mandarins in Irian Jaya, Indonesia. It was not detected in Papua New Guinea or north Queensland (Australia). Review of Plant Pathology, 80(4), p 359 (2645).
Liriomyza trifolii (EPPO A2 quarantine pest) occurs in Uttar Pradesh, India. Review of Agricultural Entomology, 89(1), p 45 (310).
Microcephalothrips abdominalis (EPPO Alert List) is present in Florida, US. Review of Agricultural Entomology, 89(1), p 49 (344).
Opogona sacchari (EPPO A2 quarantine pest) was recently found in Guangdong, China, where it caused serious damage to ornamental plants. Review of Agricultural Entomology, 89(3), p 339 (2548).
Scirtothrips aurantii (EPPO A1 quarantine pest) occurs in Mpumalanga Province, South Africa. It causes severe fruit lesions on mango fruits (Grové et al., 2000).
Xanthomonas axonopodis pv. citri (EPPO A1 quarantine pest) was identified on citrus (in small and isolated foci) in Irian Jaya, Indonesia. Review of Plant Pathology, 80(4), p 359 (2644).
- New host plants
In the Punjab Province of Pakistan, Cotton leaf curl begomovirus-Pakistan was found in radish plants (Raphanus sativus) showing symptoms of leaf curl and enations (Mansoor et al., 2000).
In Thailand, melon (Cucumis melo var. reticulatus) plants showing symptoms of a yellow leaf disease have been observed since 1983. Molecular studies revealed the presence of a virus showing 97% sequence similarity with Tomato leaf curl begomovirus from India (Samretwanich et al., 2000).
