The red - striped soft scale insect Pulvinaria tenuivalvata attacking sugar - cane at Attfieh region , Giza Governorate is considered an economic important insect pest on sugar - cane in Egypt recentlyThe main topics of this present study can be summarized as follows : Population dynamics of Ptenuivalvata , its rate of growth and survey of predators and parasitoids associated were conducted through careful inspection of sugar - cane fieldsNymphal infestation started from apical part of plant in the two studying seasonsAlso , adult infestation started on apical part of sugar - cane plant in first and second seasonsIn both seasons infestation disappear from January to the end of seasonNegative Correlation was found between the population density of Ptenuivalvata and temperature
