“…The half-lives were 16.51 days (ACE), 5.14 days (CLO), 7.23 days (IMI), and 65.22 days (THA). Due to different microbes and factors, the biodegradation rate differed among other streams [ 39 ]. The biodegradation percentage of CLO was only 37% in 37 days at 30 °C; the half-life of THA was 20.9 h; and 64.4% of IMI was degraded in 6 days in different water environments [ 40 ].…”

Neonicotinoid insecticides (NEOs) are commonly used to prevent unwanted insects in urban fields. Degradation processes have been one of the important environmental behaviors of NEOs in an aquatic environment. In this research, hydrolysis, biodegradation, and photolysis processes of four typical NEOs (i.e., thiacloprid (THA), clothianidin (CLO), acetamiprid (ACE), and imidacloprid (IMI)) were examined through the adoption of response surface methodology–central composite design (RSM-CCD) for an urban tidal stream in South China. The influences of multiple environmental parameters and concentration levels on the three degradation processes of these NEOs were then evaluated. The results indicated that the three degradation processes of the typical NEOs followed a pseudo-first-order reaction kinetics model. The primary degradation process of the NEOs were hydrolysis and photolysis processes in the urban stream. The hydrolysis degradation rate of THA was the highest (1.97 × 10−5 s−1), and that of CLO was the lowest (1.28 × 10−5 s−1). The temperature of water samples was the main environmental factor influencing the degradation processes of these NEOs in the urban tidal stream. Salinity and humic acids could inhibit the degradation processes of the NEOs. Under the influence of extreme climate events, the biodegradation processes of these typical NEOs could be suppressed, and other degradation processes could be further accelerated. In addition, extreme climate events could pose severe challenges to the migration and degradation process simulation of NEOs.

“…Bees biosynthesize limited types of enzymes endogenously that can be enhanced by phytochemicals, but a large pool of candidate bacteria could generate more types of enzymes to efficiently detoxify various pesticides that bees cannot. Bees obtain exogenous bacteria from natural food (namely, horizontal transmission) or endogenous bacteria mainly from former generations (vertical transmission), with the latter being dominant in eusocial bees (honey bees and bumble bees) in nature. ,, In addition, more exogenous bacteria may be used for probiotic formulations that are (1) found in the environment (soil, water, or sediment) and selected for bioremediation of pesticide-contaminated environments, (2) found in plants, animals, and insects that evolved to be capable of detoxifying pesticides, or (3) currently used in probiotics for humans, animals, and bees. ,− A series of bacteria have demonstrated the capacity to detoxify pyrethroids, − organophosphates, ,, neonicotinoids, − a combination of several insecticides, and herbicides and fungicides (Supporting Information Table 2). More bacterial candidates can be discovered by genomic and omic technology as well as microbe databases. ,,− …”

The ongoing global decline of bees threatens biodiversity and food safety as both wild plants and crops rely on bee pollination to produce viable progeny or high-quality products in high yields. Pesticide exposure is a major driving force for the decline, yet pesticide use remains unreconciled with bee conservation since studies demonstrate that bees continue to be heavily exposed to and threatened by pesticides in crops and natural habitats. Pharmaceutical methods, including the administration of phytochemicals, probiotics (beneficial bacteria), and recombinant proteins (enzymes) with detoxification functions, show promise as potential solutions to mitigate pesticide poisonings. We discuss how these new methods can be appropriately developed and applied in agriculture from bee biology and ecotoxicology perspectives. As countless phytochemicals, probiotics, and recombinant proteins exist, this Perspective will provide suggestive guidance to accelerate the development of new techniques by directing research and resources toward promising candidates. Furthermore, we discuss practical limitations of the new methods mentioned above in realistic field applications and propose recommendations to overcome these limitations. This Perspective builds a framework to allow researchers to use new detoxification techniques more efficiently in order to mitigate the harmful impacts of pesticides on bees.

“…The frequent metabolic reactions included nitro reduction, demethylation, cyano hydrolysis, hydroxylation, olefin, guanidine and urea formation, ring-opening, etc. Moreover, some articles have discussed the metabolic pathways of neonicotinoid insecticides in plants ( Motaung 2020 ) (spinach ( Ford & Casida 2008 ), pistachio ( Faraji et al, 2017 ), and onion ( Thurman et al, 2013 )) and environments ( Faraji et al, 2017 ) (soil ( Anjos et al, 2021 , Ma et al, 2021 ) and water ( Carla et al, 2014 , Matthew et al, 2016 )) using high-resolution mass spectrometry (HRMS). There are differences in the metabolism, translocation, and accumulation of neonicotinoid metabolites in various substrates.…”
