Elwan, E.A., Shalaby, M.S.I., & Khewa, M.M. 2005 Efficiency of some insecticides for control Pulvinaria tenuivalvata (Newstead) (Homoptera: Coccidae) on sugarcane in Naga-Hammadi District, Qena governorate.. Egyptian Journal of Agricultural Research 83(4): 1649-1661.

Notes: An experiment was conducted in Naga-Hammadi district, Egypt, during 4 September 2002 and 15 September 2003 to evaluate the efficiency of Actellic 50% EC (pirimiphos-methyl), Sumithion 50% EC (fenitrothion), Malathion 57% EC (malathion), Malatox 50% WP (malathion), Dimethoate 40% EC (dimethoate) and Dursban 48% EC (chlorpyrifos) for the control of Pulvinaria tenuivalvata. The insecticides were highly effective against the insect populations in both 2002 and 2003. Actellic was the highest effective compound (99.1%) on the nymphal populations followed by Sumithion in the second order (98.4%). Dursban came in the third order (96.9%). Dimethoate, Malatox and Malathion came in the last order (96.1, 96 and 95.7%). Similar results were observed with the adult populations where the highest effective compound was Actellic (96.9%) followed by Sumithion and Dursban in the 2nd order (95.8 and 95.2%). Malatox, Dimethoate and Malathion came in the last order (93.3, 93.2 and 93%). On the other hand, the efficiency of the tested insecticides on insect populations (nymphs and adults) combined over the 2 years indicated that, Actellic was the highest effective compound (98.7%) followed by Sumithion in the 2nd order (98.2%) and Dursban in the 3rd order (96.4%). Dimethoate, Malatox and Malathion came in the last order (95.8, 95.4 and 95.3%).
