Since the 1990s, the insect growth regulator pyriproxyfen and pyrethroids such as fenpropathrin have been widely used to reduce pest populations in agriculture. The widespread use of these insecticides makes it essential for researchers to understand how they behave in terrestrial ecosystems and how they can be detected. This work reviewed the most effective analytical techniques used to detect pyriproxyfen and fenpropathrin in various samples. The degradation of pyriproxyfen and fenpropathrin in soil takes time, but in aerobic environments, pyriproxyfen and fenpropathrin are degraded rapidly following first-order kinetics or pseudo-first-order kinetics. Both insecticides tend to adsorb on soils and are not susceptible to leaching into groundwater. Based on greenhouse or field conditions, both insecticides degrade differently by following first-order kinetics, and their half-lives in plants range from one to three weeks. Since both insecticide residues are soluble in acetone, hexane, ethyl acetate, and acetonitrile, they can be extracted in those solvents. They can also be processed in a variety of ways discussed in this paper. Ultimately, the review explains how fate profiles of pyriproxyfen and fenpropathrin in soil and plants affect these molecules' adverse effects on non-target organisms.

“…Currently, there are around 50 thousand of articles indexed in Scopus for pesticide and analysis within article titles, abstracts, and keywords, but only around 139 articles or 0.3 % if Indonesia and detection are added to the query filter. Moreover, to our knowledge, detection of pesticide in Indonesian plants or plant products are mostly related to tea [ 1 – 4 ], cacao [ 5 , 6 ], coffee [ 7 ], with only two reports in vegetables: that are shallot [ 8 ], potato and tomato [ 9 ], but none in rice and fruits. These limited reports may imply either low cases of pesticide detection- or a low number of pesticide analysis.…”

The first proficiency testing of pesticides in fruits and vegetables in Indonesia is reported. This report covers the findings of five-year proficiency testings. Every year, from 2016 to 2020, 18–25 laboratories join the proficiency testings and analyze 5–11 pesticides in tomato, orange, lettuce, brown rice, strawberry respectively. The number of laboratories participating in the proficiency testings tends to increase, although only 38 % of the laboratories are able to report all pesticides. More than 72 % of participants use QuEChERS or its modifications for sample preparation, all participants use gas chromatography or liquid chromatography for separation, at least 20 % of participants still rely on detectors other than mass spectrophotometer for detection, and 20 %–60 % of participants use matrix-matched calibration for quantification. The performance of laboratories is evaluated as z -score with an average of 90.8 % achieves satisfactory results while 3.3 % and 5.9 % achieve questionable and unsatisfactory results correspondingly. Overall, the performance of laboratory participants during proficiency testings is good. However, improvement is still needed, especially for the number of target pesticides for multi-residue pesticide analysis. Moreover, unsatisfactory z -scores are likely to be resulted from laboratories which use conventional solvent extraction, use detectors other than mass spectrometers, and are not accredited.
