Abstract Mealybugs (Hemiptera: Pseudococcidae) are major pests of a wide range crops and ornamental plants worldwide. Their high degree morphological similarity makes them difficult to identify limits their study management. We aimed set markers for the genetic characterization identification complexes taxa in Pseudococcidae. surveyed tested used previous studies then identified new particularly relevant genomic regions which no satisfactory were available. all on subset four distributed...
Scale insects are frequent invaders. With 129 established species, they numerically represent one of the major group alien to Europe. Scales usually small with wingless females. Due this size and concealment, many mainly belonging families Diaspididae, Pseudococcidae Pseudococcidae, have been accidentally introduced Europe, mostly originating from tropical regions essentially Asia. The trade fruit trees ornamentals appears be usual pathway introduction. At present, scales an important...
Abstract Epitrix species (Coleoptera: Chrysomelidae) feed mostly on plants from the family Solanaceae and some of them are major pests potato crops. All morphologically highly similar, which makes difficult to identify limits their study management. Identification is based observation genitalia requires a high level expertise. Here, we propose tool reliably all developmental stages most economically important feeding in Europe North America ( cucumeris, similaris, tuberis, subcrinita...
Abstract Pseudococcidae (mealybugs) is a large taxonomic group, including number of agronomic pests. Taxonomic identification mealybug species recurrent problem and represents major barrier to the establishment adequate pest management strategies. We combined molecular analysis three DNA markers (28S-D2, cytochrome oxidase I internal transcribed spacer 2) with morphological examination, for 176 specimens collected from 40 populations infesting various crops ornamental plants in Egypt France....
Mealybugs (Hemiptera: Pseudococcidae) are pests constraining the international trade of Brazilian table grapes. They damage grapes by transmitting viruses and toxins, causing defoliation, chlorosis, vigor losses favoring development sooty mold. Difficulties in mealybug identification remain an obstacle to adequate management these pests. In this study, our primary aim was identify principal species infesting major grape-producing regions Brazil, morphological molecular characterization. Our...
Abstract Mealybugs are major pests of grapevines worldwide. They cause economic losses by lowering the cosmetic value fruits, reducing yields, transmitting viruses and resulting in quarantine or rejection produce international trade. Knowledge species present a vineyard is important for adjustment management strategies. We surveyed accurately characterized mealybugs infesting vineyards one main production areas Chile; 164 were sampled from 26 four regions Chile identified DNA sequencing two...
Pseudococcus comstocki (Hemiptera: Pseudococcidae) is a mealybug species native to Eastern Asia and present as an invasive pest in northern Italy southern France since the start of century. It infests apple pear trees, grapevines some ornamental trees. Biocontrol programmes against this proved successful central North America second half 20th In study, we investigated possible biocontrol agents P. comstocki, with aim developing programme France. We carried out systematic DNA-barcoding at...
Scale insects (Sternorrhyncha: Coccoidea) are one of the most invasive and agriculturally damaging insect groups. Their management development new control methods currently jeopardized by scarcity identification data, in particular regions where no large survey coupling morphological DNA analyses have been performed. In this study, we sampled 116 populations armored scales (Hemiptera: Diaspididae) 112 soft Coccidae) Chile, over a latitudinal gradient ranging from 18°S to 41°S, on fruit...
Deux nouvelles espèces de Pseudococcidae du genre Phenacococus sont signalées pour la première fois en Egypte, Phenacoccus parvus et P. solenopsis. Une clé d''identification est proposée différencier les cinq connues Egypte.
A preliminary inventory of scale insects (Hemiptera: Coccoidea) developing on the mango tree is presented for Northern and Central Benin. The following species, Gigantococcus euphorbiae, nigroareolatus, Ceroplastes uapacae, Parasaissetia nigra, Saissetia privigna, Udinia catori, Ferrisia virgata, Paracoccus interceptus, Phenacoccus solenopsis, Rastrococcus invadens, Aonidiella orientalis Lepidosaphes tapleyi, were collected from 2005 to 2007 in orchards Sudanian area Benin, branches, leaves,...
Abstract In Europe, the meadow spittlebug Philaenus spumarius is main known vector of quarantine bacterium Xylella fastidiosa . So far detection and identification X has more often been performed from plant matrices than insects, mainly using a real‐time PCR multilocus sequence typing (MLST) approach. Detection in its insect vectors would enhance knowledge epidemiologic situation France, specifically already infected Corsica Provence‐Alpes‐Côte d’Azur (PACA) regions. The aim this study was...
Around 2004, a new type of injury was noticed in potato tubers harvested the north Portugal. Two North American flea beetles, Epitrix cucumeris and similaris were later identified. The second species seems to be responsible for characteristic tuber observed. main morphological characters enabling two distinguished are presented.
Cycas species and their relatives have been a staple in the Florida landscapes for 50 years. In last 25 to 30 years popularity of these plants landscape has increased worldwide. 1996, devastating pest cycads was intro duced into Florida, cycad Aulacaspis scale (Aulacaspis yasumatsui Takagi). This insect since plagued both homeowner grower alike significant many other areas world. The origin Cycad (CAS) is from Southeast Asia where it described Thailand by Takagi (1977) specimens col lected...
The Serra Gaúcha region is the most important temperate fruit-producing area in southern Brazil. Despite mealybugs (Hemiptera: Pseudococcidae) infesting several host plants region, there a lack of information about composition species damaging different crops. A survey mealybug associated with commercial fruit crops (apple, persimmon, strawberry and grapes) was performed between 2013 2015, using both morphology DNA analyses for identification. abundant were Pseudococcus viburni (Signoret),...
A new species of mealybug from Chile, Pseudococcus meridionalis Prado sp. n., is described and illustrated based on the morphological molecular characterization adult females. This belongs to “Pseudococcus maritimus” complex displays a wide host plant range, including Japanese pear, persimmon, pomegranate, pear grape.
During the summer and autumn of 2014 mealybugs Maconellicoccus hirsutus (Green, 1908) (Hemiptera: Pseudococcidae) Phenacoccus peruvianus Granara de Willink, 2007 were observed in different localities Sousse (Tunisia). This is first record for both these species Tunisia North Africa. For M. hirsutus, this was also a Western Mediterranean country. It on Hibiscus rosa‐sinensis (Malvacae). P. collected from Bougainvillea glabra (Nyctaginaceae) Citharexylum quadrangularis (Verbenacae).
Trois espèces de Cochenilles invasives sont nouvellement citées pour l’île Maurice : Paracoccus marginatus Williams & Granara Willink, 1992, Phenacoccus solenopsis Tinsley, 1898, et Planococcus kenyae (Le Pelley, 1935).
In August 2013, Phenacoccus madeirensis Green, (Hemiptera: Pseudococcidae) was identified for the first time in Tunisia, region of Akouda (Sousse, coastal area Tunisia) on Cestrum nocturnum (Solanaceae) during a survey. The infestation observed leaves, shoots and also collar. This is record P. Tunisia this pest North Africa. Two other mealybugs Peliococcus cycliger Planococcus citri were recorded They have previously been reported Tunisia.
Eriococcus munroi> (Boratynski) (Eriococcidae) est nouvellement signalé comme nuisible au Lavandin en France. En complément, Phenacoccus madeirensis Green et Spilococcus halli (McKenzie & Williams) sont signalés de France pour la première fois.
