Abstract
A field experiment was carried out during April, 2010 in olive orchard cultivated in Sarapium, Ismailia Governorate to evaluate the efficiency of six insecticides against the olive psyllid, Euphyllura straminea Loginova (Homoptera : Psylloidea, Aphalaridae) on olive trees. The obtained results showed that, the tested insecticides were highly effective against the olive psyllid, E. straminea and protect the new emergency flowers from insect damages. The highest effective compounds on the nymphal population were Fenitrothion and Phosmet (98.25 - 98.50%) followed by Imidacloprid (98.17%) and Pyriproxyfen (97.82%) whereas Chlorpyrifos and miscible mineral oil were the least effective (94.68 - 94.74%), respectively. Also, Fenitrothion and Phosmet were the highest effective insecticides on the adult population showing 98.11 - 98.32% followed by Pyriproxyfen and Chlorpyrifos (97.31 - 97.58%). Imidacloprid (96.35%) and Mineral oil came in last order (94.35%). The percentages of reduction in the insect population reached its maximum by the 4th week, it reached more than 97% for the nymph and adult populations. The obtained results revealed that, the post-spraying counts must be continue 4 weeks after application to determine the efficiency of the evaluated insecticides for control the olive psyllid E. straminea on olive trees.
