Abstract<\/strong><\/p>\n\n\n\n

The current work was carried\nout at the El-Mattana Agricultural Research Station, Luxor Governorate during\nthe 2016\/17 and 2017\/18 seasons to assess the best possible expression to S.\nsacchari<\/em> (SS)infestation and its population ecology. Six promising sugarcane\ncultivars  were  utilized. Six infestation techniques\nof SS<\/em> were applied (i.e. Population density (PD), infested internode\nnumbers (IIN), IIN %), infested stalk numbers (Isn), Isn % and infestation index\n(II)). For determination PD, nymphs, females, adult females and all stages were\ndetected to select the best expression for PD. All stages of SS<\/em> per 10\nplants were used because the females and the adult females were small numbers. The population\necology of SS<\/em> is changed, now sexual dimorphism not available because the\nmale is absent but the parthenogenetic mode of reproduction is only observed in\nEgypt. Sep had the highest\nrates of infestation across two seasons.  The  largest  ranges  for  nymph\n &  all  stages  were  between  15  Aug\n and  15  Dec  and  for  females and adult\nfemales  between  15  Aug  and  1  October. G3\nand GT54-9 were highly sensitive and G4 had a high tolerance. At the same\ntime, the grades G48-47, G2003-44 and G 99-103 are moderately susceptible to SS\n<\/em>infestation. The  cultivars  being  tested  as\n well  as  the  seasons  varied  greatly  in  their\n susceptibility  to  S.<\/em> sacchari<\/em> based   on \n the   various  \ntheir  <\/em>properties or seasons. The comparing correlations between climatic parameters and infested\ntechniques revealed that the best expression for SS<\/em> to infest sugarcane\nwas IIN%, Isn and Isn%.<\/p>\n\n\n\n

Key words: <\/strong>Sugarcane, Saccharicoccus sacchari<\/em>, Population ecology.<\/p>\n\n\n\n
