Abstract
Cheletogenes ornatus (CF 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.
