Date palms are known as the imperious crop producing good quality fruits. Red palm weevil (Rhynchophorus ferrugineus) is
recognized as the invasive pest of palm trees throughout the world. In Pakistan, date palm is being cultivated in various
provinces but infestation and population dynamics of Red palm weevil (RPW) not yet been reported. The objective of the
present study was to determine the population abundance and infestation of RPW in Pakistan having a connection with climatic
factors (temperature and humidity) by the implementation of (ferrugineol + ferrulure) pheromones and hand picking in palm
trees. Regarding the infestation level, a positive relationship was recorded between the populations and temperature while
negative effect was observed with relative humidity. The maximum average population of RPW recorded during April, May
and June in Punjab, Sindh, KPK and Baluchistan. Adult weevils collected from different provinces were found high during
April (Punjab 18.76; Sindh 24.42; KPK 11.26; Baluchistan 8.16 /trap). During survey, In Punjab, the highest 10.75±2.06
weevils were found on Mozawati from Layyah, and 13.00±3.69.5 on Kechnanr from Bahawalpur. The population recorded on
Kechanr from D.I Khan and Baluchistan were 17.60 4.74 and 6±1.25, respectively. The highest larval population 11.75±2.12
and 14.18±3.50 was also recorded on same date palms from Layyah and Bahawalpur region, respectively whereas 18.54±3.98
on Kechanr from D.I. Khan and 6.5±1.23 on Mozawati from Baluchistan was documented. Overall minimum weevils were
collected from Zeri and Denda (0.09±0.07, 0.25±0.12) in different districts. Maximum % infestation calculated from Layyah
was 12%±2.16 on Mozawati, 15.75%±1.70 on Hilawi from Sindh and 17.75%±2.75 and 7%±1.41 on Kechanr from DI Khan
and Baluchistan, respectively. This study will be helpful to manage date palm weevil keeping in view its infestation on various
date palm varieties and climatic condition.
