Life history of the flat-mite, Brevipalpus phoenicis (Geijskes)‎ ( Acari : Prostigmata: Tenuipalpidae)‎ on Navel orange variety (Citrus sinensis (L.)‎)‎

الملخص EN

Biology of Brevipalpus phoenicis (Geijskes, 1936) was studied on leaves of navel orange at two temperature degrees 25 and 30°C and 70 % R.H.

The lengths of embryonic and post-embryonic period were affected by due to the temperature degrees, where the mite was showed better development and higher fecundity at 30°C and 70 % R.H .The total immature time was averaged 16.32 & 14.23 day and 12.93 & 12.04 day for females and males at temperature degrees 25 and 30°C, respectively, while the life cycle was averaged 24.32 & 21.73 and 19.03 &17.94 day for females and males at temperature degrees 25 and 30°C, respectively.

In addition, the fecundity of B.

phoenicis was affected by temperature degrees where it averaged 11.66 & 16.23 eggs/ female by daily rate 21.24 & 2.12 egg / female /day at temperature degrees 25 and 30°C, respectively
