“…Imidacloprid and acetamiprid are extensively used in pest management of different crops (Abdallah, Hanafi, et al, ; Abdallah, Abdel Ghani, & Hrouzková, ), and the neonicotinoid family share heralded by imidacloprid is 20% of the current insecticide market (Kagabu, ). The obtained results are in agreement with those obtained by El‐Saeid and Al‐Dosari () for a survey of pesticide residues in date fruits from a market in Riyadh City, Saudi Arabia. They detected fungicide, insecticide and herbicide residue concentrations that violated the MRL values in some samples.…”

“…This is the first study to identify and quantify 42 pesticides in dates using a QuEChERS and LC‐MS/MS technique. No published data exists on monitoring and evaluating the hazards of pesticide residues in dates in Saudi Arabia with the exception of a study performed by El‐Saeid and Al‐Dosari (). The main goals of the present study were to validate a simple, multi‐residue method based on liquid–liquid extraction and LC‐MS/MS techniques to identify and quantify 42 pesticides in dates collected from large markets in Saudi Arabia and to assess their health impact on consumers.…”

A sensitive, simple and rapid QuEChERS extraction method and liquid chromatography equipped with triple quadrupole mass spectrometry (LC-MS/MS) were used to determine 42 pesticides in dates. Acidified acetonitrile and citrate buffer salts were used to extract re-hydrated samples. Acceptable validation performances were achieved, i.e. recovery range of 70-120% and RSD values ≤20% for 42 analytes at three different concentrations:100, 50 and 10 μg/kg. This method was used to analyse 200 date fruit samples (var. Sukkari) collected from different large markets in the Al-Qassim region in Saudi Arabia. Pesticide residues were detected in 36 (18%) of the date fruits samples, and 15 samples (7.5%) exceeded the maximum residue levels. The ruggedness test results showed that this method is robust and suitable for the determination of pesticide residues in dates. Additionally, the results showed that the monitored dates did not have a health impact on consumers in Saudi Arabia during the study period.

“…Synthetic insecticides have been used to manage the populations of R. ferrugineus (Aljabr et al 2014; Al‐Shawaf et al 2010; Shar et al 2012). Although several insecticides have been found to be potent, environmental pollution and development of insecticide resistance limit their efficacy on red palm weevils (Al‐Ayedh et al 2016; EL‐Saeid & AL‐Dosary 2010; Kamel et al 2007). Al‐Ayedh et al (2016) mentioned that synthetic pesticides do not provide an effective control on R. ferrugineus .…”

The red palm weevil, Rhynchophorus ferrugineus, is the biggest pest of various palm species. The aim of this study was to evaluate the impact of the essential oils of purslane, mustard and castor (bulk and nano) on R. ferrugineus and to evaluate the oviposition deterrent effect to prevent new infestations. Prepared concentrations of essential oils (bulk and nano) were tested for their impact on R. ferrugineus larvae, pupae and adults. The most effective oil was purslane oil (bulk and nano), followed by mustard and the least effective was castor. The percent mortality of larvae was 75.2, 45.3 and 17.9% (bulk phase) and 92.5, 84.4 and 65.5% (nano phase) in purslane, mustard and castor, respectively, when treated with the high concentration. The percent mortality of adults was 67.2, 40.0 and 15.6% (bulk phase) and 83.5, 72.9 and 60.0% (nano phase) in purslane, mustard and castor, respectively, when treated with the high concentration. The number of eggs laid decreased with increasing concentration of the tested oils. Purslane essential oil showed good impact on R. ferrugineus larvae and adults followed by mustard and castor oils as bulk and as nano.

“…The detection principle of AChE biosensor is based on the changes in the activity of AChE composure to the pesticides before and after. Following enzymatically catalysed hydrolysis of acetylthiocholine, the oxidation current of thiocholine is produced and monitored by instrument [18]. Scognamiglio et al have designed and developed a miniaturized multitask biosensor array system for the detection of endocrine disrupting chemicals which is equipped with an optical excitation detection system, a current measurement and flow control system [19].…”
