seasonal activity and spatial distribution of eoteranychus frosti mcgregor, tydeus longisetosus (elbagouy and momen) and zetzellia mali ewing were studied during 9th july to 22th october 2006 in an unsprayed apple orchard, maragheh region, northwest of iran. also the density dependence interaction between preys and predator was assessed. to estimate the spatial distribution pattern of these spe...

The fauna of the family Stigmaeidae Oudemans on grapevines and weed plants associated with vineyard agroecosystem in the state of Rio Grande do Sul (Brazil) was studied. Five recognized species were reported: Agistemus brasiliensis Matioli et al., 2002, Agistemus floridanus Gonzales, 1965, Agistemus mendozensis Simons, 1967, Zetzellia agistzellia Hernandes and Feres, 2005, and Zetzellia malvina...

study of the spatial distribution of a pest and its natural enemies provides better decision tool for integrated pest management. the spatial distribution and seasonal activity of panonychus ulmi (koch) and its predator zetzellia mali (ewing) were studied in an apple orchard in khoramdareh (zanjan province, iran) during 2007. the interaction (density dependence) between the prey and its predato...

Two new species of Zetzellia Oudemans, Z. agistzellia sp. n. and Z. quasagistemas sp. n., are described from rubber trees of northwestern São Paulo State, Brazil. Females have clear features of Zetzellia, whereas males resemble Agistemus in some characters. Immatures are also described. The discovery of these species raises some problems concerning generic concepts in Stigmaeidae. Since feature...

the grape erineum mite (gem), colomerus vitis (pagenstecher) (acari: eriophyidae) is considered to be one of the most important pests, that sometimes causes irreversible damages to grapevine cultivars in western parts of iran. studies were carried out in order to find natural enemies associated with gem, during 2011-2013. results indicated that natural enemies included two species of predatory ...
