Hemiptera

Kondo, Takumasa & Cortés, Ronald Simbaqueba, 2014, Sarucallis kahawaluokalani (Kirkaldy) (Hemiptera: Aphididae), a new invasive aphid on San Andres island and mainland Colombia, with notes on other adventive species, Insecta Mundi 2014 (362), pp. 1-10 : 4

( Hemiptera : Liviidae )

Of all recent invasive species, Diaphorina citri ( Fig. 2A ) has received particular attention because it is a confirmed vector of the phloem limited gram-negative bacterium Candidatus Liberibacter asiaticus, one of the pathogens that cause the devastating citrus disease “Huanglongbing” (HLB) or citrus greening disease ( Halbert and Manjunath 2004, Grafton-Cardwell et al. 2013). Besides being a vector of HLB, the Asian citrus psyllid, D. citri , can cause direct damage to its host plant by sucking large amounts of sap, injecting toxins that cause malformation of leaves and shoots and by inducing sooty molds that grow on the honeydew they produce ( Michaud 2004). Diaphorina citri has a worldwide distribution; in South America it is known from Argentina, Brazil, Colombia, Paraguay, Uruguay and Venezuela ( Augier et al. 2006, Cermeli et al. 2007, EPPO 2005, ICA 2010a). In Colombia, D. citri was reported in Colombia for the first time in 2007 and has been recorded since from the States of Antioquia, Atlántico, Bolívar, Caldas, Cauca, Cesar, Córdoba, Cundinamarca, Magdalena, Meta, Norte de Santander, Quindío, Risaralda, Santander, Sucre, Tolima, and Valle del Cauca ( ICA 2010a).
