Red palm weevil, R. ferrugineus (Coleoptera: Dryophthoridae) is the principal insect pest attacks date palm all over Egypt,
Current work aims to take advantage of effective, ecofriendly, and safer plant sources in pest control. Toxicity of some
plant crude extracts on both normal and nano form against eggs and larvae stags of RPW was assessed in laboratory exposure
experiments. The treatments comprised three different concentration of plant extracts (5, 10 and 15 mg/100 ml) for both
normal and nano extracts of selected plants using aquatic solutions. Data showed that all the evaluated extracts showed
potential ovicidal and larvicidal activity against RPW, nano extracts recorded the highest ovicidal and larvicidal
activities compared to normal extract, as ovicidal potential eucalyptus nano extract at 15% was the most toxic which
give (80.00±1.00%) mortality, (LC50=9.011) followed by oleander nano extract at 15% 76.67±0.58% (LC50=9.48)
and Datura extract at 15 (70.0±1.0 %) (LC50=9.652), while, in Larvicidal activity, nano eucalyptus was the highest
effect among all extraction (LC50=5.228) followed by Oleander(LC50=6.042).
