Valuing and controlling the economic losses from red palm weevils (Rhynchophorus ferrugineus) in Riyadh, Saudi Arabia
Abstract: Abstract: The current study was carried out to estimate the economic losses caused by red palm weevils in Riyadh, KSA. A well-planned questionnaire and personal interviews from 200 date palm farmers carried out for primary data collection. Bernoulli or binomial distribution methodology and standard errors at 95% confidence level used for estimating the value of removed palm trees. Results of the study revealed that the average incidence of red palm weevils in the sampled farms was 42.5 percent. Due to heavy infestation, 20 to 167 palm trees were removed from the various studied farms, this ranged, 3.94 percent of the total and 9.28 percent of the total infested palm trees. Due to the rapid spread of red palm weevils and removal of severely infested palms, date palm production reduced between 20.0 to 35.1 percent at a confidence level of 95% in the sampled farms. In case of Riyadh region, this decline in date production ranged between 20.57 and 32.83. Further, the value of removed date palms ranged between 85.65 to 715.15 thousand riyals in 2017. Across Saudi Arabia, this value was about 43.23 million riyals in 2016 and 2017. The result of the current study recommends the necessity of adopting the principle of integrated management of the control program of red palm weevil in the Kingdom of Saudi Arabia
