The presented paper considered the pollen morphology of thirteen species belonging to seven genera of the Fabaceae family occurring in the Pau-de-Fruta Special Protection Area (SPA), Diamantina, state of Minas Gerais, Brazil. The pollen grains of six species of Chamaecrista [C. cathartica (Mart.) H.S. Irwin & Barneby, C. debilis Vogel, C. flexuosa (L.) Greene, C. hedysaroides (Vogel) H.S. Irwin...

ABSTRACT Galls are structures of vegetal tissue modified by several biological agents, mainly dipterans the Cecidomyiidae family. The galls indicators gall inducers’ presence, because species-specific interaction between inducer and its host plant species. aim this study was to expand geographical distribution cecidomyiids – usually known only type-locality in species Andira Lam. (Fabaceae) dis...

The walnut twig beetle, Pityophthorus juglandis Blackman, and associated fungus Geosmithia morbida Kolařík, Freeland, Utley, & Tisserat constitute the insect-fungal complex that causes thousand cankers disease in walnut, Juglans spp., and wingnut, Pterocarya spp. Thousand cankers disease is responsible for the decline of Juglans species throughout the western United States and more recently, th...

Abstract The Walnut Twig Beetle (WTB), Pityophthorus juglandis Blackman, is a small bark beetle native to Mexico and Southwestern USA recorded for the first time in Europe (NE Italy) 2013. WTB attacks walnut ( Juglans spp.) wingnut trees Pterocarya vector of Geosmithia morbida Kolarík et al., pathogen causing thousand cankers disease (TCD). TCD represent serious threat orchards Europe. Spatiote...

The late Early Pleistocene was the last time of equable climate in northern Central Italy, reflected its large mammal fauna and numerous palynological records. Reliably dated leaf fossils from this are rare, but provide crucial information on local regional vegetation, biogeographic relationships, species turnover coinciding with assembly modern forest biomes. Here we investigated a rich assemb...

Thousand Cankers Disease (TCD) of Juglans and Pterocarya (Juglandaceae) involves a fungal pathogen, Geosmithia morbida, and a primary insect vector, Pityophthorus juglandis. TCD was described originally from dying Juglans nigra trees in the western United States (USA), but it was reported subsequently from the eastern USA and northern Italy. The disease is often difficult to diagnose due to the...
