| Abstract |
Pulvinaria tenuivalvata (Newstead) is an economic important insect pest on sugarcane in Upper Egypt governorates. The severe infestation causes economic loss in sugarcane quantity and quality, it can destroy the crop entirely and increases the loss of sugar production causing a shortage of sugar supply in Egypt.
The present work was conducted in Naga-Hammadi district for two years (Sep. 4th 2002 &. Sep. 15th 2003) to evaluate the efficiency of six organophosphorus insecticides for control the insect and protect the sugarcane crop from the insect damage.
The obtained results showed that, the tested insecticides were highly effective on the insect populations in the both years (2002/2003). The statistical analysis of the tested organophosphorus insecticides combined over the two years showed that, Actellic was the highest effective compound (99.1%) on the nymphal populations followed by Sumithion in the 2nd order (98.4%). Dursban came in the 3rd order (96.9%). Dimethoate, Malatox and Malathion came in the last order (96.1%, 96% and 95.7%).
The same trend of the experiments compounds was observed with the adult populations, the highest effective compound was Actellic (96.9%) followed by Sumithion and Dursban in the 2nd order (95.8% &. 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 the insect populations (nymphs and adults) combined over the two 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%).
