Some biological aspects of the red palm Weevil, Rhynchophorus ferrugineus (Olivier) as influenced by rearing on certain palm varieties, temperature and relative humidity [electronic resource].

Includes reference.

Certain biological aspects of Rhynchophorus ferrugineus (Olivier) (larval and pupal periods, male and female longevity as well as female fecundity of eggs) were studied for two successive years from 22/6/2005 to 22/6/2007 on five varieties of palms (Hayani, Eglany, Amry, Zaghlool date palms and Pritchardia ornamental palm ) under laboratory conditions. The obtained data revealed that the durations of larvae and pupae were high significantly affected by the tested varieties during the 1st and 2nd generations. Longevity of both males and females insignificantly and high significantly influenced with palm variety during the 1st generation, but during the 2nd one the opposite is true. The highest mean numbers of eggs/female (107.33 and 127.50) were deposited in case of Amry and Zaghlool date palm varieties in the 1st and 2nd generations, respectively. The fecundity of females resulted in case of Pritchardia ornamental palm variety was the least during the two aforementioned generations.
