| Abstract | ||||
| The experimentation was carried out during two successive seasons, (2015 and 2016) on mature Fig trees farm, at Dar-Ramad, Fayoum Governorate. Three chemicals, Diazenox 60%, Cidial L50 % and Renoban 48%, were tested against the bark beetle Hypothenemus eruditus (Westwood) on Fig trees. Three concentrations of each 1.5, 3.0 and 4.5cm3/1-liter water were used in addition to water alone as untreated control (untreated cuts). Counting entrance and exit holes, cidial L50 was the most effective insecticide where no holes were observed in the treated cuts at all concentrations, in both seasons with Renoban, the number of entrance holes was low with no exit holes in the 1st season and 5.7 holes/cut on cuts treated with 4.5cm/liter in the 2nd season. Diazenox was the least efficient where, after two months of exposure, there was no difference in infestation (14.2 holes/cut) between those treated with 1.5% conc. and the untreated. Results in both season were similar. | ||||
