Abstract
Three cucumber varieties namely Zena, Thamin and Sweet crunch were cultivated during nili 2005 and summer 2006 seasons on the farm of Plant Protection Research Institute, Dokki, Giza to evaluate its susceptibility to the tarsonemid pest P.latus infestation. The relationship between the mite different stages populations and someplant leaves phytochemical components were also investigated.
Sweet crunch proved to be the most susceptible variety to mite infestation, while Zena variety was tolerant and Thamin was moderately infested.
The relationship between the population density of P.latus eggs, immatures and adults on the three tested varieties was significantly positive with true protein, but significantly negative with total hydrolysable carbohydrate, total sugars, non- reducing sugars and total phenolic compound. On the other extreme, the relationship was insignificantly negative with phosphorous and potassium elements, but it was insignificantly positive with reducing sugars.
