Hole, U.B., & Salunkhe, G.N. 1998 Evaluation of rose cultivars against red scale (Aonidiella aurantii Maskell).. Journal of Maharashtra Agricultural Universities 22: 199-201.
Notes: Studies with thirty cultivars of Rosa spp. evaluated against red scale Aonidiella aurantii under field conditions in India indicated that cv. Mabella had the lowest population of scales, whereas cv. Maharaja S.S.N. was affected by the greatest number of scales. The cultivars with greater amounts of moisture, chlorophyll, nitrogen, phosphorus and lower amounts of carbohydrates coupled with a greater number of thorns per unit area appeared to have greater infestation levels of scales.
