High impact information on Tefluron

• Randomized clinical trial to investigate the effectiveness of teflubenzuron for treating sea lice on Atlantic salmon [1].
• The teflubenzuron was administered in the feed at a dosage of 10 mg kg(-1) biomass d(-1) for 7 d [1].
• No appreciable resistance to novaluron or chlorfluazuron was observed in a field strain of Spodoptera littoralis collected from cucumber field in the central part of Israel. On the other hand, the field strain showed a mild resistance of about 4-fold to teflubenzuron as compared to the laboratory susceptible strain [2].
• Two insect growth regulators, namely CME 134 and Dowco 439, have been tested for their effect on growth and on aflatoxin B1 and lipid productivity in Aspergillus flavus [3].
• The results obtained indicate degradation of teflubenzuron by soil microorganisms to be a process to be mediated by microbial consortia, and starting with hydrolysis of the phenylurea bridge by several bacterial species [4].

Associations of Tefluron with other chemical compounds

• Administration of diflubenzuron (1-5 ppm), flufenoxuron (0.025 ppm), and teflubenzuron (1-5 ppm) reduced Culex quinquefasciatus larvae in ditches by 40-90% [5].

Analytical, diagnostic and therapeutic context of Tefluron

• A bioassay to investigate the effects of exposing Capitella sp I and Capitella sp B to sediment spiked with environmentally relevant concentrations of teflubenzuron (8.4, 25 and 41.8 microg/g dry wt. sediment) is described [6].
• In the field, AC-291898 at the rates of 0.005 and 0.01 lb AI/acre caused 85 and 100% inhibition of adult emergence of Cx. tarsalis 2 days after treatment [7].
