Diflubenzuron - an overview | ScienceDirect Topics
Diflubenzuron is less effective on the Colorado potato beetle, Leptinotarsa decemlineata, than lufenuron or hexaflumuron (Karimzadeh et al., 2007). Diflubenzuron is relatively nontoxic to mammals and birds. The LD 50 for rats and mice is > 4640 mg/kg. The LC 50 for zebra fish (96 h) is > 0.2 mg/L, and it is nontoxic to bees (LD 50 > 100 μg/bee).

Diflubenzuron (DFB) is a benzoylurea insect growth regulator, that inhibits chitin synthesis, widely used for arthropod pests’ control in agriculture, forestry, public health programs, and veterinary medicine. In general, DFB is recognized as less toxic and more selective than other synthetic insecticides and therefore, considered relatively ...
A systematic review on the eco-safe management of mosquitoes …
Feb 1, 2023 · In agriculture, diflubenzuron registered trademark formulations (Dimilin®) were initially for the control of locusts and grasshoppers. Diflubenzuron (DFB) is a halogenated benzoylphenyl urea, an effective stomach and contact insecticide that acts by inhibiting chitin synthesis and interferes with the formation of the cuticle.
Diflubenzuron - an overview | ScienceDirect Topics
Diflubenzuron is a white crystalline solid that is almost insoluble in water. It is a stable compound in acidic and neutral environments but hydrolyses under alkaline conditions. It is difficult to degrade in sterilized water, but rapidly breaks down under field conditions. Diflubenzuron has low mobility and is not easily absorbed or ...
Bioaccumulation and elimination, acute toxicity analysis and risk ...
Sep 1, 2023 · The diflubenzuron concentrations in carp tissues versus time initially increased and sequentially decreased. And the diflubenzuron residues in carp tissues increased to the peak concentration at the 4th or 5th day, indicated that diflubenzuron was absorbed and enriched by fish body during initial stage of exposure experiment.
Chronic diflubenzuron exposure causes reproductive toxic effects …
May 1, 2023 · The detection of diflubenzuron in fish muscle was carried out following a previously described protocol (Zhou et al., 2022). Muscle samples were collected from female marine medaka after removing the fish's head and guts. Diflubenzuron-d4 was added to the muscle samples overnight at 4 °C as a surrogate standard.
Novel ability of diflubenzuron as an inhibitor of mitochondrial ...
Apr 1, 2024 · Diflubenzuron (DFB) inhibits the expression of α-smooth muscle actin in cancer-associated fibroblasts (CAFs) and suppresses the CAF-mediated cancer cell invasion. DFB inhibits the expression of actin and myocardin-related transcription factor (Mrtf) in insect tissues and Schneider S2 cells, leading to cell growth suppression.
Dissipation rates and residue levels of diflubenzuron and ...
Nov 1, 2019 · The MEs of diflubenzuron and difenoconazole were −10% and −6%, respectively, indicating that the proposed purification method was effective.As shown in previous papers, if the ME ranges from −10% to 10%, then it can be ignored; otherwise, a matrix-matched standard solution should be used to ensure the accuracy of the method (Zhu et al ...
Diflubenzuron leads to apoptotic cell death through ROS …
Aug 1, 2021 · Diflubenzuron suppresses cell viability and cell proliferation The cytotoxic effect of DFB on the viability of MAC-T cells were investigated using the MTT assay. After the cells were treated with wide concentration ranges of DFB for 48 h, we observed that the viability gradually reduced with increase in concentration ( Fig. 1 A ).
Rapid on-site immunoassay for diflubenzuron in grains
Sep 18, 2002 · An antibody-based test for field use has been developed to enable a screening test for diflubenzuron in animal feed grain. In this test, a pesticide containing methanol extract of the grain sample and an HRP-labeled diflubenzuron derivative are separately added to the antibody-precoated 8-well strip. After a brief incubation period, the strip ...
