Effects of diflubenzuron on the mouse liver

Journal of Applied Toxicology, 1986
AbstractDiflubenzuron (DFB), a potent inhibitor of insect chitin synthesis, was administered to Swiss Webster mice in a 30‐day oral intubation study. Animal groups received either no treatment, vehicle control (Polyehylene glycol 400), or DFB suspensions at doses of 125, 500, and 2000 mg/kg body weight.

Effect of diflubenzuron on an estuarine crustacean

Bulletin of Environmental Contamination and Toxicology, 1979
In a review of one of the newer insecticides, diflubenzuron (Dimilin, TH-6040, [ i( 4-chloropher@l )-3( 2,6-dlfluorobenzoyl ) urea]), MARX (1977) emphasized that its ability to i~pair chltin synthesis, leading to toxicity in insects, is useful for controlling several insect pests.

Metabolism of Diflubenzuron in Lizard (Eremias argus) and Comparative Toxicity of Diflubenzuron and Its Metabolite

Journal of Agricultural and Food Chemistry, 2018
The metabolic process of diflubenzuron in rat or fish has been well studied, but little is known about its elimination pathway in lizard. The current study predicted the metabolic route of diflubenzuron in lizard feces and compared the toxicity of diflubenzuron and 4-chloroaniline on lizard thyroid system.

Analysis of diflubenzuron by gas chromatography/mass spectrometry using deuterated diflubenzuron as internal standard

Journal of Agricultural and Food Chemistry, 1991
A new and rapid gas chromatography/mass spectrometry analytical procedure for insect growth regulator diflubenzuron, a phenylurea-based insecticide, has been developed. Diflubenzuron is decomposed by the heat of a gas chromatograph into three reproducible fragments, 4-chlorophenyl isocyanate, 4-chloroaniline, and 2,6-difluorobenzamide, which elute ...

Persistence of Diflubenzuron on Soybean Leaves

Journal of Entomological Science, 2004
Diflubenzuron [Dimilin™, N-[{(4-chlorophenyl)amino}carbonyl]-2-6-difluorobenzamide] is an insect growth regulator that is highly effective and provides residual control (up to 54 days) against velvetbean caterpillar, Anticarsia gemmatalis Hübner, on soybean, Glycine max (L.) Merrill, in Louisiana.

The accumulation and elimination of diflubenzuron by fish

Bulletin of Environmental Contamination and Toxicology, 1979
In summary, diflubenzuron is accumulated from water into fish tissues at levels up to 80 fold within 24 hr when fish are exposed to concentrations of 10 ppb. Within the concentration range of 1-10 ppb, the amount accumulated in a 24 hr exposure is proportional to concentration. After 24 to 48 hr exposure fish degrade and eliminate diflubenzuron and the

Diflubenzuron: Intestinal absorption and metabolism in the rat

Xenobiotica, 1980
1. The metabolic fate of the insecticide diflubenzuron was investigated in the rat with radioactively labelled forms of the compound. 2. Intestinal absorption, measured as the sum of urinary and biliary excretion, diminished greatly with increasing dose, from about 50% at 4 mg/kg to about 4% at 900 mg/kg. 3.

Diflubenzuron larvicide auto-dissemination: A modeling study

Acta Tropica
Proposing substitutes for Pyriproxyfen (PPF) in the auto-dissemination strategy is essential to ensure the continuity of the strategy in the field, especially in the case of the emergence of populations resistant to this larvicide. One possible substitute among the compounds already in use in Brazil is the larvicide Diflubenzuron (DFB).

Ecotoxicological effect of diflubenzuron

36. Savetovanje dezinfekcija, dezinsekcija i deratizacija jedan svet - jedno zdravlje - zbornik radova
Diflubenzuron is an insecticide from the group of insect growth regulators, widely used in agriculture and forestry for pest control. Its application can have negative effects on non-target organisms and ecosystems. In the environment, diflubenzuron degrades through hydrolysis, photodegradation, and microbial activity, producing 4-chloroaniline (4-CA),

Determination of diflubenzuron in apples by gas chromatography

Journal of Chromatography A, 1997
A method for the determination of residues of the insecticide diflubenzuron, 1-(4-chlorophenyl)-3-(2,6-difluorobenzoyl)urea, in apples using gas chromatography with electron-capture detection has been developed and validated. The three solvents ethyl acetate, acetone and dichloromethane were tested for extraction of diflubenzuron residues from apples ...
