New Records and Updated Checklist of the Pentatomoidea (Hemiptera: Heteroptera) of Greece.

Eight species of the superfamily Pentatomoidea are recorded from Greece for the first time: Küster 1852, (Fabricius 1775), (Scopoli 1763), (Herrich-Schaeffer 1830), (Gallen 1789), (Linnaeus 1758), (Fabricius 1775) and (Jakovlev 1871). A complete updated species checklist with distributional data notes for all the new species for Greece are provided.

Identification and Seasonal Abundance of Auchenorrhyncha With a Focus on Potential Insect Vectors of Xylella fastidiosa in Olive Orchards in Three Regions of Greece.

Studies of the species composition, seasonal appearance, and abundance of Auchenorrhyncha in olive crops is of paramount importance to reduce the potential of Xylella fastidiosa to invade new areas. As similar investigations had not previously been conducted in Greece, extensive surveys were undertaken in olive orchards located in three of the most important regions for olive production in central Greece (Fthiotida), south-central Greece (Attica), and southern Greece (Chania). Surveys took place over a 13-mo period, using Malaise traps examined on a monthly basis.

New records and updated checklist of Cicadomorpha (Hemiptera: Auchenorrhyncha) species from Greece.

Seventeen auchenorrhynchan species of the family Cicadellidae are recorded from Greece for the first time: Euscelidius variegatus (Kirschbaum 1858), Euscelis ohausi (Wagner 1939), Psammotettix notatus (Melichar 1896), Psammotettix striatus (Linnaeus 1758), Psammotettix sabulicola (Curtis 1837), Anzygina honiloa (Kirkaldy 1906), Arboridia versuta (Melichar 1897), Edwardsiana ishidae (Matsumura 1932), Edwardsiana tersa (Edwards 1914), Eupteryx decemnotata (Rey 1891), Eupteryx curtisii (Flor 1861), Eupteryx rostrata (Ribaut 1936), Frutioidia sanguinosa (Rey 1891), Zygina rosea (Flor 1861), Zygina suavis (Rey 1891), Zygina tiliae (Fallen 1806), Anaceratagallia frisia (Wagner 1939). Faunistic and distributional data notes are given for each species and a complete, updated species checklist for Greece is provided.

Nano-formulation enhances insecticidal activity of natural pyrethrins against Aphis gossypii (Hemiptera: Aphididae) and retains their harmless effect to non-target predators.

The insecticidal activity of a new nano-formulated natural pyrethrin was examined on the cotton aphid, Aphis gossypii Glover (Hemiptera: Aphididae), and the predators Coccinella septempunctata L. (Coleoptera: Coccinellidae) and Macrolophus pygmaeus Rambur (Hemiptera: Miridae), in respect with the nano-scale potential to create more effective and environmentally responsible pesticides. Pyrethrin was nano-formulated in two water-in-oil micro-emulsions based on safe biocompatible materials, i.

Biocompatible colloidal dispersions as potential formulations of natural pyrethrins: a structural and efficacy study.

Biocompatible colloidal dispersions of the micro- and nanoemulsion type based on lemon oil terpenes, polysorbates, water, and glycerol were used for the formulation of pyrethrins, botanical insecticides derived from the white pyrethrum daisy, Tanacetum cinerariifolium. The proposed formulation is based on pyrethrin-containing water-in-oil (W/O) microemulsions that could be diluted in one step with an aqueous phase to obtain kinetically stable oil-in-water (O/W) nanoemulsions. Structural characteristics of the micro- and nanoemulsions were evaluated by electron paramagnetic resonance (EPR) spectroscopy, dynamic light scattering (DLS), small angle X-ray scattering (SAXS), and electrical conductivity.

Effect of temperature on development and survival of the parasitoid Pnigalio pectinicornis (Hymenoptera: Eulophidae) reared on Phyllocnistis citrella (Lepidoptera: Gracillariidae).

Laboratory studies were conducted to assess the effect of temperature on the development and survival of the indigenous parasitoid Pnigalio pectinicornis L. on the citrus leaf miner Phyllocnistis citrella Stainton as host, fed on leaves of Citrus sinensis L. Osbck cultivar Washington navel and Citrus reticulata Blanco cultivar Clementine.
