First detection of chlorfenapyr (Secure) resistance in two-spotted spider mite (Acari: Tetranychidae) from nectarines in an Australian orchard.

Exp. Appl. Acarol. 31(1-2) , 131-4, (2003)

Chlorfenapyr resistance (2.9- and 19.9-fold respectively at LC50 and LC99 level) was detected in Tetranychus urticae Koch causing control failure following a single application of product to nectarines.

New developments in insecticide resistance in the glasshouse whitefly (Trialeurodes vaporariorum) and the two-spotted spider mite (Tetranychus urticae) in the UK.

Pest Manag. Sci. 58(2) , 123-30, (2002)

A recent survey of insecticide resistance in two of the most problematic pests in UK glasshouses revealed some new developments. At least some individuals in all UK samples of Trialeurodes vaporariorum that were tested resisted the insect growth regulator (IG...

Ultraviolet radiation increases sensitivity to pesticides: synergistic effects on population growth rate of Daphnia magna at low concentrations.

Bull. Environ. Contam. Toxicol. 87(3) , 231-7, (2011)

In the present study we aimed to investigate whether UV-B radiation can exacerbate effects of pesticides fenoxycarb, pirimicarb, and tebufenpyrad on the survival, reproduction, and population growth rate of the standard test species Daphnia magna. We applied ...

Incidence and inheritance of resistance to METI-acaricides in European strains of the two-spotted spider mite (Tetranychus urticae) (Acari: Tetranychidae).

Pest Manag. Sci. 57(5) , 443-8, (2001)

A strain of Tetranychus urticae (Koch; Acari: Tetranychidae), collected from hops (Humulus humuli L; Cannabaceae) in England with a short history of tebufenpyrad use, exhibited resistance to four METI (mitochondrial electron transport inhibitor)-acaricides; t...

[Acute tebufenpyrad and tolfenpyrad poisoning in humans].

Chudoku. Kenkyu. 23(4) , 324-8, (2010)

Design, synthesis, and insecticidal activity of novel pyrazole derivatives containing α-hydroxymethyl-N-benzyl carboxamide, α-chloromethyl-N-benzyl carboxamide, and 4,5-dihydrooxazole moieties.

J. Agric. Food Chem. 60(6) , 1470-9, (2012)

On the basis of commercial insecticides tebufenpyrad and tolfenpyrad, two series of novel pyrazole-5-carboxamides containing α-hydroxymethyl-N-benzyl or α-chloromethyl-N-benzyl and pyrazoles containing 4,5-dihydrooxazole moieties were designed and synthesized...

Improved regioselectivity in pyrazole formation through the use of fluorinated alcohols as solvents: synthesis and biological activity of fluorinated tebufenpyrad analogs.

J. Org. Chem. 73(9) , 3523-9, (2008)

The preparation of N-methylpyrazoles is usually accomplished through reaction of a suitable 1,3-diketone with methylhydrazine in ethanol as the solvent. This strategy, however, leads to the formation of regioisomeric mixtures of N-methylpyrazoles, which somet...

Synthesis of new fluorinated Tebufenpyrad analogs with acaricidal activity through regioselective pyrazole formation.

J. Org. Chem. 73(21) , 8545-52, (2008)

In previous studies, our group has shown that the use of fluorinated alcohols such as trifluoroethanol (TFE) and hexafluoroisopropanol (HFIP) as solvents dramatically increases the regioselectivity in the pyrazole formation from 1,3-diketone with methylhydraz...

Cross-resistance, inheritance, and biochemistry of mitochondrial electron transport inhibitor-acaricide resistance in Tetranychus urticae (Acari: Tetranychidae).

J. Econ. Entomol. 94(6) , 1577-83, (2001)

Resistance of the twospotted spider mite, Tetranychus urticae Koch, to acaricides acting as mitochondrial electron transport inhibitors (METIs) is an increasing problem. Because of their high levels of cross-resistance to all commercially available METI-acari...

Sublethal effects of tebufenpyrad on the eggs and immatures of two-spotted spider mite, Tetranychus urticae.

Exp. Appl. Acarol. 36(3) , 177-85, (2005)

Sublethal effects of the mitochondrial electron transport inhibitor (METI) tebufenpyrad on Tetranychus urticae Koch females surviving treatment as eggs or immatures (> or =90% mortality) were investigated in life-table assay. The developmental time of females...
