To reduce the number of seeds released by Hakea sericea after fires, two seed-feeding insects were introduced into South Africa from Australia in 1970: a seed-moth, C. autologa, the larvae of which destroy the seeds in mature fruits, and a seed-feeding weevil Erytenna consputa, the larvae of which...

Successful establishment of invasive species requires that the species meet environmental conditions favouring their longevity and fecundity. When juveniles and adults consume different resources, gravid females may have to choose whether to feed or to reproduce. We used a successful invasive...

Several permanent populations of Thrips hawiiensis (Morgan) were discovered outdoors for the first time in 2015, in different sites in Italy. The species widely distributed and common in tropical countries is now recorded from three European countries: France, Spain and Italy. It is a phytophagous...

The plum seed wasp, Eurytoma schreineri Schr. (Schreiner, 1908) is non-native species insect for Bulgarian fauna. This species was first recorded in Bulgaria in 2013, in the regions Dobrich and Silistra, in the northeastern part of the country. E. schreineri is oligophagous. The larva feeds in the...

A population of the Indian wax scale (Ceroplastes ceriferus) was detected in Budapest, Bikáspark (Hungary) in November 2016, which is a new species to the Hungarian fauna. Overwintering females were found on hybrid plane (Platanus × acerifolia), mullberry (Morus alba) and silver maple (Acer...

Ionizing radiation is used as a phytosanitary treatment to mitigate risks from invasive species associated with trade of fresh fruits and vegetables. Commodity producers prefer to irradiate fresh product stored in modified atmosphere packaging that increases shelf life and delays ripening. However, ...

Rhagoletis completa Cresson (Diptera: Tephritidae) is native to North America and invaded Western Europe in the late 1980s, causing important damage to its principal host, walnut (Juglans spp.). In this review, we summarize the important elements of R. completa's biology, phytosanitary status and...

Plants with animal-dispersed fruits seem to overcome the barriers that limit their spread into new habitats more easily than other invasive plants and, at the same time, they pose special difficulties for containment, control or eradication. The effects of animals on plant propagules can be very...

The type of reproductive system may be an important trait for the establishment and maintenance of populations of invasive plant species in new areas, as it can influence their demography and genetics. We studied the breeding system of two exotic invasive species, Rosa rubiginosa and R. canina, in...

Question: How did the native and alien woody plant communities of protected lowland wet forests of a tropical oceanic island change in the presence of understorey invasive alien plants over the medium (21-27 yrs) and longer term (68 yrs)? Location: Bel Ombre, Brise Fer and Macchabé forests in the...
