Abstract

The Present Work Aims To Study The Effect Of Some Weather Factors On Population Fluctuation Of The Two Most Prevalent Phytophagous Mite Species In Cotton Fields. The Effect Of Day Maximum Temperature, Night Minimum Temperature And Daily Mean Relative Humidity On Might Populations Is Studied. Also, The Effect Of Temperature And Relative Humidity On Preoviposition Period, Egg Incubation Period, Oviposition Period Longevity And Fecundity Of Females, Is Investigated. Finally, The Effect Of Temperature And Relative Humidity On The Immature Stages Is Studied.
