Abstract
Greenidea psidii is an invasive insect from Asia that feeds on a diverse variety of agriculturally and environmentally important plant species. As an essential component of research necessary for development of a better understanding of biodiversity and its conservation, this study documents a major recent expansion in range of G. psidii in the Neotropics to the region of the tropical restinga ecosystem of Brazil, where it was found infesting guava (Psidium guajava) and jabuticaba (Plinia cauliflora). A summary of information on the geographic distribution, host plants, identification, and potential natural enemies of G. psidii that may be useful for integrated management of this pest in the Neotropical Region and other areas where this invasive insect has recently become established and is likely to further spread is also provided.
Highlights
The insect Greenidea (Trichosiphum) psidii van der Goot (Hemiptera: Aphididae) is an invasive pest that feeds on ecologically and economically important plants of the family Myrtaceae such as guava (Psidium guajava), and has been recorded from plants in a diverse variety of other families (Halbert 2004; Pérez Hidalgo et al 2009)
Aphid specimens collected from a heavily infested guava and jabuticaba plants growing in Vitória, Espírito Santo in 2014 were identified as G. psidii
Culik et al SpringerPlus (2016) 5:734 in Espírito Santo is more than 700 km from the locale of previous records of the species in South America [Curitiba and Morretes, Paraná; Penha, Santa Catarina; and São Paulo, São Paulo, Brazil (Lazzari et al 2006)], this record of G. psidii documents a major new expansion in the distribution of this invasive pest in the Neotropics
Summary
The insect Greenidea (Trichosiphum) psidii van der Goot (Hemiptera: Aphididae) is an invasive pest that feeds on ecologically and economically important plants of the family Myrtaceae such as guava (Psidium guajava), and has been recorded from plants in a diverse variety of other families (Halbert 2004; Pérez Hidalgo et al 2009). Greenidea psidii is originally from Asia and has recently invaded many other areas such as the United States, Costa Rica, and Mexico (Halbert 2004; Pérez Hidalgo et al 2009; Salas-Araiza et al 2011) where it has become established and has caused concern as a pest of agriculturally valuable crops such as guava as well as environmentally important native species such as jabuticaba (Plinia cauliflora).
