Molecular and morphological characterisation of Pseudococcidae surveyed on crops and ornamental plants in Spain

Beltrà Ivars, Aleixandre; Soto Sánchez, Antonia Isabel; Malausa, Thibaut (Cambridge University Press (CUP), 2012-04)

[EN] Mealybugs (Hemiptera: Pseudococcidae) are common invasive pests in Europe, causing major problems on crops and ornamental plants. However, very few data are available concerning the mealybug fauna of southern ...
Molecular evidence for ongoing complementarity and horizontal gene transfer in endosymbiotic systems of mealybugs

Lopez-Madrigal, Sergio; Beltrà Ivars, Aleixandre; Resurreccion, Serena; Soto Sánchez, Antonia Isabel; Latorre, Amparo; Moya, Andres; Gil, Rosario (Frontiers Media, 2014-08-26)

[EN] Intracellular bacterial supply of essential amino acids is common among sap-feeding insects, thus complementing the scarcity of nitrogenous compounds in plant phloem. This is also the role of the two mealybug ...
