Abstract

The influence of different degrees of temperature 15, 20, 25. 30 & 35°C and
70::!:5% R.H. was investiqated on the developmental stages, fecundity, feeding
capacity and life table parameters of the predatory mite Neoseiulus neoreticulatus
Yousef & EI-Brollosy when fed on immature stages of the spider mite Tetranychus
urticae Koch under laboratory conditions. The obtained data revealed that the higher
temperature degree the shorter period of different stages.
Female and male longevity decreased when temperature increased from
15-35°C, whereas female longevity amounted 525, 30.8, 18.4, 12.3 and 9.4 days at
15,20,25,30 and 35°C respectively.
It could be concluded that life table parameters affected by temperature
degrees, whereas, 30°C gave the highest, net reproductive rate (Ro), survival rate
and rm values as 25.8. 0.90 and 0.27 respectively.
