Abstract
Cheletogenes  ornatus  (C&F)  developed  and reproduced  on three  different types  of food,  crawlers  of  the  scale  insect, Hembeiisia  lataniae  (Signoret);  immatures  of Eutetranychus  orientalis (Klein) and the  acarid mite,  Tyrophagus putrescentiae  (Shrank)  at 20 &25±2°C  ald  65±5%  R.H. Females  had  two nymphal  stages; while males  had only one. Predator was found  for  the  first  time  in  high numbers on  aromatic  and  medicinal  plants,  (Jasmine)  Lonicera japonica Thunb.  (F:  Caprifoliaceae)  hiding under  H.  lotaniae,  scale  insect  and  in  low  numbers  with  Fig  fruit  trees  during  study period.  As temperature  changed between 20  and 25°C,  the  incubation  and  both  male  and female  immature  stages  periods decreased.  Temperature also  decreased  significantly on  the  adult female  and male longevity.  C.  ornatus lived  longer  on crawlers  of  H. iataniae  than other  tested  foods.  The developent at  25°C was  faster  than  at  20°C  a Significant  greatest number of  deposited  eggs  by  female  was  96±2.97  at 25°C when  fed  on  H.latania  scale insect  crawlers;  while it  was 48 eggs/female  it  20°when fed on  acarid  mite. Life  table  parameters  showed  that,  The  mean generation time  (T) and doubling  time  (DT)  values  decreased  with temperature  increase.  The values  of  rm ; Ro and λ )  increased  with temperature increase.  Also  crawlers of  scale  insect  was the  favorable  followed  by phytophagous  mites  then  acarid  mite.
