Abstract
The present work aims to study the Population dynamics of RPW Rhynchophorus. ferrugineus (Oliv.) adults in relation to certain climatic factors using attracting pheromone traps on date palm plantation. Experiments were conducted during two successive years (2009 and 2010) in Wardan and Abu-Ghalep villages, 6th October Governorate. The diurnal flying activity of RPW were also considered. The obtained results showed that adults emerging continually throughout the year. The lowest adults population was recorded during December and January. The population showed four peaks each year. There were four peaks of emergence during 2009 at 2nd week of April, 1st week of June, 1st week of August and 2nd week of November, in 2010, four peaks were also recorded during 4th week of March , 3rd week of June, 3rd week of July and 2nd week of November. Data indicated that there was significant positive correlation between average temperature and adults population abundance of the RPW during the studied two year. While relative humidity had negative effect. The diurnal flying activity of RPW adults was studied during the tested period. The obtained data revealed that the maximum flying activity of RPW adults during day hours was at time 6.00 am followed by the time at 16.00 pm.
