“…It is possible that nontarget Lepidopterans could also develop resistance to permethrin. Resistance development in pest Lepidopteran species has been reported (Jia et al 2009 ; Grigg-McGuffin et al 2015 ; Uesugi 2020 ; Sun et al 2022 ) and has been reported in a nontarget aquatic invertebrate (Major et al 2022 ). The common aspect of this resistance development is that it occurs in organisms either targeted by the applications or are unintentionally routinely exposed to the insecticide.…”

Ground applications of adulticides via a specialized truck-mounted sprayer are one of the most common practices for control of flying adult mosquitoes. Aerosols released to drift through a targeted area persist in the air column to contact and kill flying mosquitoes, but may also drift into adjacent areas not targeted by the applications where it may affect nontarget insects such as imperiled butterflies. This study compared the risk of permethrin to adult mosquitoes and adult butterflies to assess the likelihood that the butterflies would be affected following such sprays. Permethrin toxicity values were determined for Aedes aegypti and Culex quinquefasciatus (LD50s of 81.1 and 166.3 ng/g dw, respectively) and then combined with published toxicity data in a species sensitivity distribution for comparison with published permethrin toxicity data for adult butterflies. The sensitivity distributions indicated adult butterflies and mosquitoes are similarly sensitive, meaning relative risk would be a function of exposure. Exposure of adult butterflies and adult mosquitoes to permethrin was measured following their exposure to ULV sprays in an open field. Average permethrin concentrations on adult mosquitoes (912–38,061 ng/g dw) were typically an order of magnitude greater than on adult butterflies (110–11,004 ng/g dw) following each spray, indicating lower risk for butterflies relative to mosquitoes. Despite lower estimated risk, 100% mortality of adult butterflies occurred following some of the sprays. Additional studies could help understand exposure and risk for butterflies in densely vegetated habitats typical near areas treated by ULV sprays.

“…However, developing resistant varieties and biological control approaches takes time. More importantly, Xcc is now resistant to the vast majority of chemicals, including copper‐based formulations, 7 and overused pesticides accumulate in the environment, leading to further resistance build‐up and toxicity for the environment and humans 8–10 . For these reasons, there is significant interest in the development of efficient control technologies based on nanomaterials to combat citrus canker.…”

BACKGROUNDCitrus canker caused by Xanthomonas citri subsp. citri (Xcc) is a devastating bacterial disease that reduces citrus yield and quality, posing a serious threat to the citrus industry. Several conventional chemicals have been used to control citrus canker. However, this approach often leads to excessive use of chemical agents, can exacerbate environmental pollution, and promotes the development of resistant Xcc. Therefore, there is significant interest in the development of efficient and environmentally friendly technologies to control citrus canker.RESULTSIn this study, water‐soluble ZnO quantum dots (ZnO QDs) were synthesised as an efficient nanopesticide against Xcc. The results showed that the antibacterial activity of ZnO QDs irradiated with visible light (EC50=33.18 μg/mL) was ~3.5 times higher than that of the dark‐treated group (EC50=114.80 μg/mL). ZnO QDs induced the generation of reactive oxygen species (•OH, •O‐ 2, and 1O2) under light irradiation, resulting in DNA damage, cytoplasmic destruction, and decreased catalase and superoxide dismutase activities. Transcription analysis showed down‐regulation of Xcc genes related to ‘biofilms, virulence, adhesion’, and ‘DNA transfer’ exposure to ZnO QDs. More importantly, ZnO QDs also promoted the growth of citrus.CONCLUSIONThis research provides new insights into the photocatalytic antibacterial mechanisms of ZnO QDs and supports the development of more efficient and safer ZnO QDs‐based nanopesticides to control citrus canker.

Chemical pesticides are the primary methods used to decrease vector mosquito populations ( Major et al, 2022 ), despite their limited availability due to environmental harm and non-target creatures ( Mulkiewicz et al, 2021 ). The utilisation of chemical insecticides presents greater difficulties and a variety of possible environmental issues, including their widespread emergence and their resistance to and interference with organic biological regulation mechanisms ( Reyes-Calderón et al, 2022 ).…”

The grindstone process, which uses tyrosinase as a catalyst, was used to create analogues of geranylacetone. Tyrosinase was used to prepare the Mannich base under favourable reaction conditions, resulting in a high yield. All synthesized compounds were characterized using FTIR, Nuclear magnetic resonance, and mass spectral analyses. The active geranylacetone derivatives (1a-l) were investigated for larvicidal activity against Culex quinquefasciatus; compound 1b (LD50:20.7 μg/mL) was noticeably more effective than geranylacetone (LD50: >100 μg/mL) and permethrin (LD50: 24.4 μg/mL) lead compounds because of their ability to kill larvae and use them as pesticides. All compounds (1a-1l) were found to be low toxic, whereas compounds 1b, 1d, and 1k were screened for antifeedant screening of non -aquatic target for the toxicity measurement against marine fish Oreochromis mossambicus at 100 μg/mL caused 0% mortality in within 24 h. Molecular docking studies of synthesised compound 1b and permethrin docked with 3OGN, compound 1b demonstrated a greater binding affinity (−9.6 kcal/mol) compared to permethrin (−10.5 kcal/mol). According to these results, the newly synthesised geranylacetone derivatives can serve as lead molecules of larvicides agents.
