Hemeida, I.A., El-Shabrawy, H.A., Helmy, E.I.M., & El-Sahn, O.M.N.I. 2006 Evaluation of alternative scalicides against the Hemisphaerical soft scale insect Saissetia coffeae (Walker) infesting Cycas revoluta Thunb. under semi field conditions. Egyptian Journal of Agricultural Research 84 (5):

Notes: Five compounds, two summer miscible oils, namely Super Misrona and Super Mox , winter mayonnaise oil, Alboleum, liquid soap (Misrol 410) and Ashok (a neem kernel extract) were tested against Saisetia coffeae different stages infesting Cycas palm like in El-Zoherya botanical garden at Cairo Governorate in two successive seasons (April 2003 and 2004 ). Results revealed that Alboleum ( mayonnaise oil ) gave the highest reduction O/O in the 2 seasons with 94.63 and 91.44 %, 25 days after treatment, followed by Super Mox oil (91.68 & 91.77% ), super Misrona oil ( 82.99 & 85.73 O/O ) and Misrol soap gave ( 73.84 & 73.93 O/O ), respectively. While, the neem kernel extract (Ashok) recorded the lowest reduction O/O with 27.24 & 23.77 O/O in both seasons, respectively. Analysis of data showed a significant differences between oils, liquid soap and Ashok. Also , data recorded that the nymphal stage was the most affected stage after 25 days from treatment with 75.55 and 77.23 O/O in the two experimental seasons. While adult and gravid females came next with (73.73 & 73.84 O/O ) and ( 72.95 & 68.91 %), respectively, with insignificant differences between stages in the season. From the previous mentioned data, it was clear that mayonnaise oil and the 2 miscible oils gave an excellent results as a control agents against different stages of S. coffeae at tested rate of 1.5% and 1%. Also, no phytotoxic effect observed on the tested plant leaves.
