| Abstract | ||||
| This is the first study on Red Palm Weevil Rhynchophorus ferrugineus (Oliv.) in Baharia Oases. The aim of the present work was to study the population abundance of R. ferrugineous (Oliv.) adults in relation to two climatic factors using attracting pheromone traps on date palm plantation. This work was carried out during January 2013 to December 2014 in Baharia Oases, Giza Governorate- Egypt. The obtained results recorded that adults emerging continually throughout the year. The lowest adults population was recorded during January and December in the two tested years, the population showed two peaks of adult population for each year. The first peak in 2013 recorded at the second week of April while the second peak recorded at second week of October. In 2014 the first peak recorded at second week of March and the second peak at the second week of September. There were different effects of daily mean temperature and relative humidityon the population activity of R. ferrugineous. The sex ratios of male to female were 1: 2.5 and 1: 2.4 during 2013 and 2014 respectively. | ||||
