Insecticide Residue Analyses in Cucumbers Sampled from Çanakkale Open Markets1 Çanakkale Açık Pazarlarından Örneklenen Hıyarlarda Insektisit Kalıntı Analizleri
Türk. entomol. derg., 2020, 44 (4): 449-460 ISSN 1010-6960 DOI: http://dx.doi.org/10.16970/entoted.767482 E-ISSN 2536-491X Original article (Orijinal araştırma) Insecticide residue analyses in cucumbers sampled from Çanakkale open markets1 Çanakkale açık pazarlarından örneklenen hıyarlarda insektisit kalıntı analizleri Hayriye ÇATAK2 Osman TİRYAKİ3* Abstract The aim of this study was to investigate four insecticide residues in cucumbers with the aid of QuEChERS 2007.1 method. For method verification assessment, pesticide-free cucumber matrix was spiked with 0.1, 1 and 10 times of MRL for each pesticide. The QuEChERS-LC-MS/MS analytical method revealed that the detection limits of the insecticides were below the MRLs and the overall recovery of method was 97.7%. These figures were within the SANTE recovery limits (60-140%) and the values specified for the repeatability (≤20%). Cucumbers were collected from six different stands (A-F) at Çanakkale open markets for 6 weeks between 23 November and 28 December 2018. Residues of each sampling time and each stand were assessed. Acetamiprid residue of 257g and 236 µg/kg were detected in week 5 from stand B and in week 2 from stand E, respectively. These values are close to MRL (300 µg/kg). Formetanate hydrochloride residue of the week 3 from stand F (36.3 µg/kg) was more than MRL of 10 µg/kg. Pirimiphos methyl and chlorpyrifos residues were not detected in cucumbers. Theoretical maximum daily intake assessment showed that there was no chronic exposure risk for these four pesticides through cucumber consumption. Keywords: Cucumber, insecticide residues, QuEChERS, risk assessment, toxicology Öz Bu çalışma hıyarlarda dört insektisit kalıntısını QuEChERS 2007.1 yöntemi ile belirlemek amacıyla yapılmıştır. -

Box 24885, Safat 13109, Kuwait; [email protected] (D.G.A.); [email protected] (M.S.A.); [email protected] (V.Y.D.); [email protected] (N.A.) * Correspondence: [email protected]; Tel.: +965-249-8984 Received: 1 May 2017; Accepted: 12 July 2017; Published: 25 July 2017 Abstract: The presence of pesticide residues in primary and derived agricultural products raises serious health concerns for consumers. The aim of this study was to assess the level of pesticide residues in commonly consumed fruits and vegetables in Kuwait. A total of 150 samples of different fresh vegetables and fruits were analyzed for the presence of 34 pesticides using the quick easy cheap effective rugged and safe (QuEChERS) multi-residue extraction, followed by gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass spectrometry (LC-MS/MS). Pesticide residues above the maximum residue limits (MRL) were detected in 21% of the samples and 79% of the samples had no residues of the pesticides surveyed or contained residues below the MRL. Multiple residues were present in 40% of the samples with two to four pesticides, and four samples were contaminated with more than four pesticide residues. Of the pesticides investigated, 16 were detected, of which imidacloprid, deltamethrin, cypermethrin, malathion, acetamiprid, monocrotophos, chlorpyrifos-methyl, and diazinon exceeded their MRLs. -

The toxicity of Bacillus thuringiensis subsp. aizawai (Bt GO33A) combined with chlorantraniliprole (Chl) has not been documented. Here, we examined sin- gle and combined toxicity of chlorantraniliprole and Bt to assess the levels of resistance in four DBM strains. Additionally, enzyme activities were tested in field-original highly resistant (FOH-DBM), Bt-resistant (Bt-DBM), chlorantraniliprole-resistant (CL-DBM), and Bt + chlorantraniliprole-resistant (BtC-DBM) strains. The Bt product had the highest toxicity to all four DBM strains followed by the Citation: Shabbir, M.Z.; He, L.; Shu, mixture of insecticides (Bt + Chl) and chlorantraniliprole. -
Chlorantraniliprole: Reduced-Risk Insecticide for Controlling Insect Pests of Woody Ornamentals with Low Hazard to Bees
242 Redmond and Potter: Acelepryn Control of Horticultural Pests Arboriculture & Urban Forestry 2017. 43(6):242–256 Chlorantraniliprole: Reduced-risk Insecticide for Controlling Insect Pests of Woody Ornamentals with Low Hazard to Bees Carl T. Redmond and Daniel A. Potter Abstract. Landscape professionals need target-selective insecticides for managing insect pests on flowering woody orna- mentals that may be visited by bees and other insect pollinators. Chlorantraniliprole, the first anthranilic diamide insec- ticide registered for use in urban landscapes, selectively targets the receptors that regulate the flow of calcium to control muscle contraction in caterpillars, plant-feeding beetles, and certain other phytophagous insects. Designated a reduced- risk pesticide by the United States Environmental Protection Agency, it has a favorable toxicological and environmental profile, including very low toxicity to bees and most types of predatory and parasitic insects that contribute to pest sup- pression. Chlorantraniliprole has become a mainstay for managing turfgrass pests, but little has been published concern- ing its performance against the pests of woody ornamentals. Researchers evaluated it against pests spanning five different orders: adult Japanese beetles, evergreen bagworm, eastern tent caterpillar, bristly roseslug sawfly, hawthorn lace bug, ole- ander aphid, boxwood psyllid, oak lecanium scale (crawlers), and boxwood leafminer, using real-world exposure scenarios. Chlorantraniliprole’s efficacy, speed of control, and residual activity as a foliar spray for the leaf-chewing pests was as good, or better, than provided by industry standards, but sprays were ineffective against the sucking pests (lace bugs, aphids, or scales). Basal soil drenches in autumn or spring failed to systemically control boxwood psyllids or leafminers, but autumn drenches did suppress roseslug damage and Japanese beetle feeding the following year. -
Quantitative Determination of Pyrethroids, Pyrethrins, and Piperonyl Butoxide in Surface Water by High-Resolution Gas Chromatography/High-Resolution Mass Spectrometry
J. Agric. Food Chem. 2006, 54, 6957−6962 6957 Quantitative Determination of Pyrethroids, Pyrethrins, and Piperonyl Butoxide in Surface Water by High-Resolution Gas Chromatography/High-Resolution Mass Spectrometry MILLION BEKELE WOUDNEH* AXYS Analytical Services Ltd., 2045 Mills Road West, Sidney, British Columbia V8L 3S8, Canada DANIEL RAY OROS San Francisco Estuary Institute, 7770 Pardee Lane, 2nd Floor, Oakland, California 94621 A new method for determination of pyrethroids, pyrethrins, and piperonyl butoxide (PBO) by high- resolution gas chromatography/high-resolution mass spectrometry (HRGC/HRMS) was developed for surface water samples. The method is based on sampling 100 L of ambient surface water with a solid phase extraction (SPE) technique that uses both wound glass fiber filters for collecting the particulate-associated chemicals and XAD-2 resin for collecting the dissolved chemicals. The method detection limits of the analytes ranged from 0.58 to 8.16 ng/sample, which is equivalent to a detection limit range of 0.0058-0.082 ng/L for a 100 L water sample collected by the SPE technique. The SPE when coupled with HRGC/HRMS was a suitable match for detecting these chemicals at subnanogram per liter ranges that are toxicologically significant to aquatic organisms. To confirm the utility of this method for environmental applications, pyrethroids and PBO were found at subnanogram per liter concentrations in surface water samples collected from five tributaries (primarily urban creeks) of the San Francisco Bay, California. KEYWORDS: Pyrethroids; pesticides; XAD-2; HRGC/HRMS; San Francisco Bay INTRODUCTION by inhibiting a group of enzymes (mixed-function oxidases) that are involved in pyrethroid detoxification, which as a result The decision of the U.S.
