Ecological And Biological Study For The Expansion Of The Psedococcidae
On Citrus In The Syrian Cost
Abstract
During the years 2001-2002 a survey for mealy bugs on leaves and fruits of
citrus trees was conducted at the gardens and open orchards around Lattakia and
along the Syrian Coast. The results of the study revealed the presence of the
following species: Planococcus citri Risso, Pseudococcus
comostocki Kuwana, Pseudococcus adonidium Linne at all the sites,
with the highest infestation rate of the three species being in August. The
infestation rate on the leaves in the citrus gardens around the city reached
19.13, 2.5 and 78.32% for the three species, respectively. The infestation rate
in the citrus open orchards was 40.54, 2.46 and 57.0%, respectively. P. citri
was the most common on citrus fruits. The generation duration for the
mentioned three species under Lab conditions reached 41.6±4.79, 38.1±3.70 and
39.5±5.46 days, respectively.
