Accumulation of diflubenzuron in bolti fish Orechromis niloticus
Food / Nahrung, 1991AbstractOrechromis niloticus fingerlings were exposed to the insect growth inhibitor diflubenzuron 1‐(2, 6‐Difluorobenzoyl)3‐(4‐chlorophenyl)urea for 21 days. Diflubenzuron was introduced to the aquariums where fish were maintained at the beginning of the experiment, then its level in water, gills and liver was detected after 1, 7, 14 and 21 days.

Pesticide Science, 1984
Abstract[14C]Diflubenzuron is readily degraded in various agricultural soils and in hydro‐soil; 50% of the applied dose of 1 mg kg−1 was metabolised in 2 days or less. The chief products of hydrolysis were identified as 4‐chlorophenylurea and 2, 6‐difluorobenzoic acid. A part of the radioactivity, increasing with incubation time, could not be extracted.

FATE AND DISPOSITION OF DIFLUBENZURON IN RICE FIELDS
Environmental Toxicology and Chemistry, 1996Abstract Laboratory and field investigations were undertaken to determine the fate, disposition, and persistence of the insecticide diflubenzuron in California rice culture. Water solubility was similar in distilled/deionized water (88.8 ± 4.0 μg/L) and rice field water (92.6 ± 3.5 μg/L), while the measured Henry's law constant was 2.34 ±

Utilisation du diflubenzuron en lutte antiacridienne
Zeitschrift für Angewandte Entomologie, 1979AbstractDiflubenzuron is a chemical active on Schistocerca gregaria at dosis acceptable in practice. Its efficiency however, varies in the course of intermoulting period; it is particularly hopeful two or three days before the next exuviation. Therefore its use is possible only on gregarigenous areas.RésuméLe diflubenzuron est un produit actif sur ...

Pharmacokinetics of diflubenzuron in two types of chickens
Journal of Toxicology and Environmental Health, 1984Pharmacokinetic parameters of [14C]diflubenzuron, N-([(4-chlorophenyl) amino]-carbonyl)-2,6-difluorobenzamide, in White Leghorn (WL) egg-production chickens and Rhode Island Red/Barred Plymouth Rock (RIR/BPR) meat-production chickens after single 1-mg/kg intravenous and single 5-mg/kg oral doses were investigated to explain a breed-related egg residue ...

Effects of Diflubenzuron on Benthic Macroinvertebrates in Littoral Enclosures
Archives of Environmental Contamination and Toxicology, 1996Two applications of the insect growth regulator diflubenzuron were made to replicate littoral enclosures at nominal concentrations of 0.7, 2.5, 7.0, and 30 &mgr;g/L. Assessment of the effects of this insecticide on benthic macroinvertebrate community structure was accomplished by measuring changes in abundance and taxonomic richness.

Preliminary study of synergism of acid rain and diflubenzuron
Bulletin of Environmental Contamination and Toxicology, 1995Diflubenzuron{sup 1} (Dimilin{reg_sign}) was used on over 7 million acres in the U.S. in 1990 to control forest pests, particularly the gypsy moth. This chitin synthesis inhibitor affects insects and other anthropods. It is a restricted use pesticide due to its nontarget effects on aquatic macroinvertebrates.

Investigation of locust cuticle using the insecticide diflubenzuron
Journal of Insect Physiology, 1977Abstract Diflubenzuron inhibits the synthesis of chitin ( Verloop , in prep.). Some of the resulting possibilities for the investigation of cuticle are explored in this paper. The cuticle of locusts treated with DFB is prone to fracture in characteristic ways. This is of relevance in studying the function of the exoskeleton.
