The red-striped soft scale insect Pulvinaria tenuivalvata attacking sugarcane at Attfieh region, Giza governorate is considered an economic important insect pest on sugarcane in Egypt. Laboratory evaluation of different extracts of Cressa cretica on the biological aspects of P. tenuivalvata was studied. The obtained results revealed a wide range difference in the response of the two stages (Adult and Nymphal) to the tested compounds. It was obvious that, the nymphal stage was most susceptible tested treatments while the adult stage was the most tolerant one. Petroleum ether was the most effective compound on nymphal and adult stages of P. tenuivalvata while water extract was the least toxic compound. Based on the obtained results, treatments could be used in IPM program against P. tenuivalvata.
