Mealybugs (Hemiptera: Coccomorpha: Pseudococcidae) constitute important agricultural pests that often require control measures. Different mealybug taxa might, however, react differently to natural enemies and pesticides so that appropriate control measures against mealybugs rely heavily on the correct species identification. The mealybug Planococcu...

Contexte - Les plantes ornementales abritent et alimentent un grand nombre d’espèces de cochenilles, que ce soit dans les jardins/ espaces verts, les collections botaniques ou les exploitations horticoles ornementales. C’est la raison pour laquelle les partenaires de l’UMT Fiorimed ont piloté de janvier 2017 à décembre 2019, le projet Cochorti, fin...

A new genus of Eriococcidae, Dzumacoccus Hodgson gen. n., is erected for a new species, Dzumacoccus baylaci Hodgson, Germain & Matile-Ferrero, feeding on Gymnostoma poissonianum, a species of Casuarinaceae endemic to New Caledonia. The adult female and first-instar nymph are described and illustrated.

Quarantine interception of invasive and nonindigenous insect pests at ports of entry is often impeded by the lack of robust identification methods. Because of their inconspicuous morphology and wax-covered bodies, mealybugs present a particular challenge. The present study employs DNA barcoding (658 base pairs near the 5′-terminus of the cytochrome...

The Serra Gaúcha region is the most important temperate fruit-producing area in southern Brazil. Despite mealybugs (Hemiptera: Pseudococcidae) infesting several host plants in the region, there is a lack of information about the composition of species damaging diferent crops. A survey of mealybug species associated with commercial fruit crops (appl...

En Afrique, en Europe du Sud et au Moyen-Orient, le genre Spodoptera était jusqu’à présent représenté par huit espèces, dont trois d’importance économique : S. exempta, S. exigua et S. littoralis (Brown, 1975). S. frugiperda s’ajoute à ce trio de ravageurs.

Full-text available
Scale insects (Sternorrhyncha: Coccoidea) are one of the most invasive and agriculturally damaging insect groups. Their management and the development of new control methods are currently jeopardized by the scarcity of identification data, in particular in regions where no large survey coupling morphological and DNA analyses have been performed. In...

Following the description of the species Epitrix papa Orlova-Bienkowskaja, 2015, which was previously misidentified in the EPPO region as E. similaris Gentner, 1944, the authors assessed the mitochondrial cytochrome c oxidase I (COI) sequence divergence between specimens of E. papa from Portugal and E. similaris from California. This study strongly...

The worldwide mealybug genus Paracoccus Ezzat & McConnell (Hemiptera: Coccomorpha: Pseudococcidae) has eight described Neotropical species, including two species known from Brazil. In this article, we describe a third species from Brazil: Paracoccus galzerae Pacheco da Silva & Kaydan sp. n., based on the morphology of adult females collected on the...

Pseudococcus comstocki (Hemiptera: Pseudococcidae) is a mealybug species native to Eastern Asia and present as an invasive pest in northern Italy and southern France since the start of the century. It infests apple and pear trees, grapevines and some ornamental trees. Biocontrol programmes against this pest proved successful in central Asia and Nor...
Article
In the last decade, the incidence of mealybugs (Hemiptera: Pseudococcidae) in vineyards has increased, especially on crops grown under plastic covering, in the Serra Gaúcha region of southern Brazil where the major Brazilian wineries are concentrated. Eggs, nymphs, and female adults were collected in two highly infested vineyards in Bento Gonçalves...

Brazil has the greatest insect diversity in the world; however, little is known about its scale insect species (Hemiptera: Coccomorpha). Mealybugs (Pseudococcidae) have been found in at least 50% of persimmon orchards Diospyros kaki L. in the southern part of the country. In this study three new mealybug species on persimmon trees located in the Se...

During the summer and autumn of 2014 the mealybugs Maconellicoccus hirsutus (Green, 1908) (Hemiptera: Pseudococcidae) and Phenacoccus peruvianus Granara de Willink, 2007 (Hemiptera: Pseudococcidae) were observed in different localities of Sousse (Tunisia). This is the first record for both of these species in Tunisia and in North Africa. For M. hir...

At the end of August 2014, a visitor to the French National Plant Protection service (NPPO) in Cayenne (French Guiana) brought in mango twigs covered with a significant amount of sooty mould. From these branches, the NPPO officers took large numbers of mealybugs from the underside of the leaves (Fig. 1). The sample was sent to the Plant Health Labo...

Mealybugs (Hemiptera: Pseudococcidae) are pests constraining the international trade of Brazilian table grapes. They damage grapes by transmitting viruses and toxins, causing defoliation, chlorosis, and vigor losses and favoring the development of sooty mold. Difficulties in mealybug identification remain an obstacle to the adequate management of t...

Epitrix species (Coleoptera: Chrysomelidae) feed mostly on plants from the family Solanaceae and some of them are major pests of potato crops. All Epitrix species are morphologically highly similar, which makes them difficult to identify and limits their study and management. Identification of species is mostly based on the observation of the genit...

Pseudococcidae (mealybugs) is a large taxonomic group, including a number of agronomic pests. Taxonomic identification of mealybug species is a recurrent problem and represents a major barrier to the establishment of adequate pest management strategies. We combined molecular analysis of three DNA markers (28S-D2, cytochrome oxidase I and internal t...

Mealybugs are major pests of grapevines worldwide. They cause economic losses by lowering the cosmetic value of fruits, reducing yields, transmitting viruses and resulting in the quarantine or rejection of produce in international trade. Knowledge of the species present in a vineyard is important for the adjustment of management strategies. We surv...

A new species of mealybug from Chile, Pseudococcus meridionalis Prado sp. n., is described and illustrated based on the morphological and molecular characterization of adult females. This species belongs to the "Pseudococcus maritimus" complex and displays a wide host plant range, including Japanese pear, persimmon, pomegranate, pear and grape.
Article
Mealybugs (Hemiptera: Pseudococcidae) are major pests of a wide range of crops and ornamental plants worldwide. Their high degree of morphological similarity makes them difficult to identify and limits their study and management. We aimed to identify a set of markers for the genetic characterization and identification of complexes of taxa in the Ps...
