Exotic Scale Insects (Coccoidea) on Ornamental Plants in Italy: a Never-Ending Story
Acta Zoologica Bulgarica, 2014
The introduction of ornamental plants into Italy for commercial and hobby purposes has provided scale insects with many chances of dispersion. Coccoidea often go unnoticed at border controls due to their cryptic lifestyle. Moreover, many of the introduced alien species become acclimatized outdoors, possibly due to the effects of urban pollution and global warming. The authors attempt to analyse this phenomenon and report on the records of new alien species in Italy, starting from the end of the Second World War. In the period 1945-1995, an average of 0.64 new introduced alien species were reported per year, whereas an average of 0.7/year were introduced between 1995 and 2005 and 1.25/year since 2005. About fifty alien species have been recorded so far in Italy, of which about 50% are presently acclimatized on ornamentals. The increase in alien species introduction is probably due to: the ever easier and faster transport and dispatch of plants in a globalized world trade; the free movement of goods within the European Union; and the weakness of the National Plant Protection Organization (NPPO) monitoring. Moreover the effect of global warming may have played an important role, directly enhancing the survival and development of the insects in their new environment. The authors comment and discuss the more invasive species, namely Ceroplastes japonicus Green, C. ceriferus Fabricius, Protopulvinaria pyriformis (Cockerell), Phenacoccus madeirensis Green, Phenacoccus peruvianus Granara de Willink, Phenacoccus defectus Ferris, Chrysomphalus aonidum L. and Aulacaspis tubercularis Newstead.

The Madeira mealybug, Phenacoccus madeirensis (Hemiptera: Pseudococcidae), is recorded from Jordan for the first time. Specimens were collected from heavily infested ornamental geranium plants, Pelargonium sp. (Geraniaceae), Chrysanthemum sp. (Asteroideae), Hibiscus rosa-sinensis L. (Malvaceae), Kalanchoe blossfeldiana Poellnitz (Crassulaceae) and basil, Ocimum basilicum L. (Lamiaceae). In addition, this mealybug was taken from infested leaves of cherry tomato, Solanum lycopersicum L., and sweet pepper, Capsicum annuum L. (Solanaceae). Kalanchoe blossfeldiana is recorded as a new host for P. madeirensis. Slide mounts were prepared, and voucher specimens were preserved at the University of Jordan Insect Museum. An urgent survey should be initiated to determine the current distribution of the pest in Jordan. Inspection of ornamental nurseries should be given priority and plant protection officials should pay particular attention to this serious pest.
First records of two mealybug species in Brazil and new potential pests of papaya and coffee
Journal of Insect Science, 2006
Five mealybug (Hemiptera: Pseudococcidae) plant pest species: Dysmicoccus grassii (Leonardi), Ferrisia malvastra (McDaniel), Ferrisia virgata (Cockerell), Phenacoccus tucumanus Granara de Willink, and Pseudococcus elisae Borchsenius are recorded for the first time in the state of Espírito Santo, Brazil. These are the first records of D. grassii in Brazil, from papaya (Carica papaya, Caricaceae), and from coffee (Coffea canephora, Rubiaceae). Ferrisia malvastra is also newly recorded in Brazil, where it was found on Bidens pilosa (Asteraceae). Ferrisia virgata was collected from an unidentified weed and Phenacoccus tucumanus from Citrus sp. (Rutaceae). Plotococcus capixaba Kondo was found on pitanga (Eugenia cf. pitanga, Myrtaceae) and Pseudococcus elisae on Coffea canephora, which are new host records for these mealybugs.

Inventory of ornamental plant mealybugs (Hemiptera Pseudococcidae) in Tunisia: species, host plants and distribution. In recent years, mealybugs (Hemiptera, Pseudococcidae) have become an important pest of ornamental plant in Tunisia due to their accident introduction and invasiveness. Awareness, early knowledge of invasive species, their host plant and geographical distribution could help to implement control methods which minimize the economic losses caused by them. A survey was conducted during 2013-2018 period to identify the mealybug species on ornamental plant, their host plant and document their geographic and periodic distribution. Seven species belonging to five genera were identified: Maconellicoccus hirsutus Green, Phenacoccus peruvianus Granara de Willink, Phenacoccus madeirensis Green, Planococcus vovae Nassonov, Planococcus citri Risso, Ferrisia virgata Cockerelland Pseudococcus longispinus Targioni-Tozzetti. M. hirsutuswas the most abundant mealybug and found in twenty-one sites on Hibiscus rosa-sinensis and Hibiscus mutabilis. P. peruvianus was the most polyphagous specie found on five host plants belonging to four families in eleven sites. P. citri was the single specie observed during wet season, therefore, all the rest species were found during dry season (summer, beginning autumn). These finding provide primary baseline knowledge of the mealybug fauna on ornamental plant in Tunisia and contribute information for use in the development of sustainable ornamental pest management strategies in the country.

Originating from USA and co-evolved with numerous food plants, the mealybug Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) has become a highly invasive and polyphagous pest. It is reported damaging >200 plant species from about 24 countries of tropical and subtropical regions of the world. The average length of P. solenopsis life cycle range between 28 and 35 days and it can complete about 8 e12 generations in a year, inflicting significant yield losses to cotton (Gossypium hirsutum Linn.) and other economically important crops. The devastating outbreaks of P. solenopsis on cotton causing 30e60% yield losses have been reported from India and Pakistan during 2005e2009 and since then the pest has received worldwide attention as an invasive species of quarantine importance. About 28 species of natural enemies including 12 predators and 16 multiple parasitoids of P. solenopsis have been reported throughout its range, but only an Encyrtid species Aenasius bambawalei Hayat has been instrumental in controlling P. solenopsis natural populations in a range of 30e60%. Due to the highly polyphagous nature and the ability to oviposit on a wide range of host plants, P. solenopsis has huge potential to invade new areas and to adapt to a wide range of ecological situations. This clearly indicates that P. solenopsis can pose a serious threat to agricultural and horticultural production, especially in tropics and subtropics where the temperatures are expected to increase under projected climate change. There is a need for undertaking adaptive strategies against this pest to lessen the yield losses and safeguard the interest of crop growers.
Hibiscus mealybug,Culik et al, 2013
In South America the invasive hibiscus mealybug Maconellicoccus hirsutus (Green, 1908) (Hemiptera: Pseudococcidae) has been restricted to Caribbean South America until re-cently but in 2010 it was detected in Northern Brazil in Roraima, and this is the first report of this insect in a second Brazilian State, Espírito Santo, located approximately 3.400 km southeast of Roraima. Because M. hirsutus is a potential pest of many plant species and may become more widely established in South America, pheromone traps may be useful for detecting entry into new areas and monitoring this mealybug. Although M. hirsutus has been recorded on a diverse variety of plants, apparently few are favored hosts, and in most areas where it has become established natural enemies maintain populations of this mealybug below damaging levels, indicating that besides prevention of spread of this pest, efforts should be directed toward establishment, augmentation, and maintenance (conservation) of effective natura...

Systematic Revision of the Mealybug GenusDelottococcusCox & Ben-Dov (Hemiptera: Pseudococcidae)
African Entomology, 2011
A systematic revision of the mealybug genus Delottococcus Cox & Ben-Dov is presented. Nine species are treated, including D. millari which is described as new. The eight previously described species are: Delottococcus aberiae (De Lotto), D. confusus (De Lotto), D. elisabethae (Brain), D. euphorbiae (Ezzat & McConnell), D. phylicus (De Lotto), D. proteae (Hall), D. quaesitus (Brain), and D. trichiliae (Brain). Adult females of all species are described and illustrated and a key for their identification is presented. In the past, specimens determined as D. elisabethae have been recorded from citrus and other hosts, but these appear to be misidentifications of D. aberiae. Delottococcus elisabethae is only known from the original collection. As invasive species, D. confusus is reported from California and Hawaii, D. aberiae from Spain, and D. euphorbiae from France, Italy, and Sicily.
