- New records
Aleurocanthus woglumi (Homoptera: Aleyrodidae – EPPO A1 List) is reported for the first time from Brazil. It was found in citrus and mango crops in the state of Maranhão in 2003/2004 (de Lemos et al., 2006). Present, in the state of Maranhão.
In Libya, symptoms of ‘brittle leaf disease’ of date palms (or ‘maladie des feuilles cassantes’ – formerly on the EPPO Alert List) have been reported near Waddan (municipality of Al Jufrah). The etiology of this disease is still unclear (Namsi et al., 2007). Present, in the region of Waddan (Al Jufrah municipality).
Diaphorina citri (Homoptera: Aphalaridae – EPPO A1 List, vector of citrus huanglongbing) was recently detected in Iran, it was found in some parts of Hormozgan and Sistan-Baluchestan provinces. During surveys on natural ennemies, a nymphal parasitoid of D. citri was identified as Psyllaephagus stenopsyllae (Hymenoptera: Encyrtidae) (Ameri et al., 2006). Present, in the provinces of Hormozgan and Sistan-Baluchestan.
Diaphorina citri (Homoptera: Aphalaridae – EPPO A1 List) is reported for the first time from Costa Rica (Villalobos et al., 2005). Present, no details.
Echinothrips americanus (Thysanoptera: Thripidae) is reported to occur on glasshouse crops in Poland (Fielder, 2006). Present, no details.
Liriomyza trifolii (Diptera: Agromyzidae – EPPO A2 List) occurs in Iran (Talebi et al., 2005). Present, no details.
In Southern Iran, Maconellicoccus hirsutus (Homoptera: Pseudococcidae – EPPO A1 List) is considered as an important pest (Moghaddam, 2006). Present, no details.
In Iran, Monochamus sutor (Coleoptera: Cerambycidae) was trapped in natural forests (Farashiani et al., 2006). Present, no details.
Scirtothrips citri (Thysanoptera: Thripidae - EPPO A1 List) occurs in the Khūzestān Province, Iran (Akbari ; Seraj, 2007). Present, Khūzestān province.

Anastrapha fraterculus and A. obliqua (Diptera: Tephritidae – EPPO A1 List) occurs in the State of Amapá, Brazil (da Silva ; da Silva, 2007).
The presence of the Q biotype of Bemisia tabaci (Homoptera: Aleyrodidae - EPPO A2 List) is reported for the first time in the State of Sonora, Mexico. B. tabaci biotype Q was identified on poinsettia plants (Euphorbia pulcherrima) at several nurseries (Martinez-Carillo ; Brown, 2007).
Bactrocera dorsalis (Diptera: Tephritidae – EPPO A1 List) occurs in Andhra Pradesh, India (Kannan ; Rao, 2006).
Bactrocera latifrons (Diptera: Tephritidae) occurs in Hainan Province, China (Lin et al., 2006).
In Iran, Clavibacter michiganensis subsp. michiganensis (EPPO A2 List) was first reported from Urmiyeh in the West Azerbaijan province in 1993. In 2004-2005, a collection of 102 bacterial isolates was obtained from tomato fields in the major producing areas. 98 isolates, collected from the West Azerbaijan and Golestan Provinces, were identified as C. michiganensis susbp. michiganensis (Nazari et al., 2007).
Monochamus carolinensis (Coleoptera: Cerambycidae – EPPO A1 List) occurs in Iowa, USA (Rice ; Veal, 2006).
Monochamus alternatus (EPPO A1 List) and M. urussovii (Coleoptera: Cerambycidae) occur in Jilin Province, China (Wang et al., 2007).
Pepino mosaic virus (Potexvirus, PePMV – EPPO Alert List) occurs in glasshouse tomatoes in Minnesota, USA. PePMV has frequently been found in association with an unknown tymovirus whose identity is currently being investigated (Lockhart, 2007).
Thrips palmi (Thysanoptera: Thripidae – EPPO A1 List) occurs in glasshouse rose crops in the State of Minais Gerais, Brazil (Carvalho et al., 2005).
- Host plants
Studies were carried out in Idaho and Washington states in the USA to determine the potential weed hosts of Iris yellow spot virus (Tospovirus, IYSV – EPPO Alert List). The presence of IYSV could be detected (ELISA, RT-PCR, sequencing) in the following weed species growing in infected onion fields or in their vicinity: Amaranthus retroflexus (Amaranthaceae), Chenopodium album (Chenopodiaceae), Kochia scoparia (Chenopodiaceae), Lactuca serriola (Asteraceae), Tribulus terrestris (Zygophyllaceae) (Sampangi et al., 2007).
