This study was conducted in Diyala governorate/Iraq during wintering period of the sunn pest from Dece. 2016 to Feb. 2017. Three species of sunn pest was diagnostic. These species are Eurygaster integriceps (Puoton, 1881), E. testudinaria (Geoffory, 1785) and E .maura (len.1758).E .maura  was new species recorded to Iraq funna .E. integriceps is The most abundance of the three species hibernated  in the fields of the four region of Diyala governorate. The results showed that the three species of genus Eurygaster which diagnostic in Diyala governorate were overwintered as an adults under bushes ,dead leaves, weed ,date palm leaf base .The heights total number of adults(68,56,51 and 44adults/5m2) was found under cogon grass(Imperata cylindrican L.), Bermuda grass(Cyndo dactylon L.),Grape tree(Vitis vinifera L.)and Eucalyptus tree(Eucalyptus spp.) respectively. Higher densities were recorded in Muqdadiyah (200), Balad rooz (193), Kalas (113) and decreased to( 65) adults in  Khanakin. Found that the higher percentage for species E. integriceps then followed E. testudinaria finally the species E. maura in all region in Diyala governorate.

Grape cultivation is a billion-dollar agricultural sector in California, where invasive or novel pest species can disrupt management practices. We report herein on a new pest associated with California vineyards, the carpentermoth Givira ethela (Neumoegen and Dyar, 1893). Rather than an invasive species, G. ethela appears to be a newly recognized wood-boring pest of Vitis vinifera (L.) in regions of California’s Central Valley, where its initial occurrence has been dated back to, at least, the beginning of the 2000s. The habitus of adult, genitalia and pupa is illustrated. Givira ethela distribution in California is updated including published records and new data. Carpentermoth galleries seem to facilitate the access of Planococcus ficus Signoret, 1875 to vine sap and protection from natural enemies, environmental stresses, and pesticide treatments. Notes on pest status, life history, monitoring practices, natural enemies, and management options on grapes are also discussed. Tools for the Integrated Pest Management of G. ethela should include the correct identification of the insect and its damage, a full understanding of its biology and ecology, the application of monitoring methods, and the identification of economic thresholds and injury levels.

Tissue Homogenates

Cell walls have been isolated from the mesocarp of mature grape (Vitis vinifera L.) berries. Tissue homogenates were suspended in 80% (v/v) ethanol to minimise the loss of water-soluble wall components and wet-sieved on nylon mesh to remove cytoplasmic material. The cell wall fragments retained on the sieve were subsequently treated with buffered phenol at pH 7.0, to inactivate any wall-bound enzymes and to dislodge small amounts of cytoplasmic proteins that adhered to the walls. Finally, the wall preparation was washed with chloroform/methanol (1:1, v/v) to remove lipids and dried by solvent exchange. Scanning electron microscopy showed that the wall preparation was essentially free of vascular tissue and adventitious protein of cytoplasmic origin. Compositional analysis showed that the walls consisted of approximately 90% by weight of polysaccharide and less than 10% protein. The protein component of the walls was shown to be rich in arginine and hydroxyproline residues. Cellulose and polygalacturonans were the major constituents, and each accounted for 30-40% by weight of the polysaccharide component of the walls. Substantial varietal differences were observed in the relative abundance of these two polysaccharides. Xyloglucans constituted approximately 10% of the polysaccharide fraction and the remainder was made up of smaller amounts of mannans, heteroxylans, arabinans and galactans.

Os sistemas atmosféricos exercem um papel significativo no clima de uma região e poucos trabalhos determinaram os impactos dos sistemas atmosféricos no de­senvolvimento e na produção de videira. Os objetivos deste trabalho foram deter­minar a frequência de ocorrência dos sistemas atmosféricos durante o período da maturação à colheita da videira (Vitis vinifera L.) var. Cabernet Sauvignon para as duas regiões produtoras de Santa Catarina em diferentes safras e determinar a as­sociação entre a ocorrência dos sistemas atmosféricos e as regiões produtoras e as safras. Os sistemas atmosféricos foram identificados durante as safras de 2005/2006 à 2008/2009. Os municípios de Água Doce e Campos Novos foram escolhidos para re­presentar a região produtora 1 e os municípios de Bom Retiro e São Joaquim para re­presentar a região produtora 2. As frequências de ocorrências dos sistemas atmosfé­ricos durante o período da maturação à colheita de videira são muito semelhantes entre as regiões, somente houve diferença na frequência de ocorrência do sistema jato subtropical entre regiões. Houve uma diferença significativa da ocorrência da frequência dos sistemas atmosféricos entre safras.
