Reevaluation of kinetic data for a paraoxon-hydrolyzing enzyme in a resistant strain of the predacious mite Amblyseius potentillae

Autor: F.J. Oppenoorth

Publikováno v: Pesticide Biochemistry and Physiology. 38:99-100

In a previous paper (1989, Pestic. Biochem. Physiol. 33, 283–297), on a hydrolytic enzyme as a cause of resistance, Anber and I reported that it had a k3 value for paraoxon of 0.14 per hour. It is shown here that this is impossible, and that the en

Hydrolysis of paraoxon and malaoxon in three strains of Myzus persicae with different degrees of parathion resistance

Autor: S. voerman, F.J. Oppenoorth

Publikováno v: Pesticide Biochemistry and Physiology. 5:431-443

Homogenates of three strains of Myzus persicae , A, R, and E, with an LD 50 for topically applied parathion of 9, 93, and 263 ng per aphid, showed an in vitro hydrolytic degradation of paraoxon of 2.3, 4.7, and 8.6 pmol/mg aphid/h, respectively. Thes

Insensitive acetylcholinesterase, high glutathione-S-transferase, and hydrolytic activity as resistance factors in a tetrachlorvinphos-resistant strain of house fly

Autor: W. Welling, L.J.T. van der Pas, F.J. Oppenoorth, H.R. Smissaert, K.T. Hitman

Publikováno v: Pesticide Biochemistry and Physiology. 7:34-47

The gene producing insensitive acetylcholinesterase in a tetrachlorvinphos-resistant strain of house fly was introduced into the genome of a susceptible strain. The resistance to a number of organophosphorus insecticides, which was high in the origin

Biochemistry of insecticide resistance

Autor: F.J. Oppenoorth

Publikováno v: Pesticide Biochemistry and Physiology. 22:187-193

After briefly summarizing various resistance mechanisms and their effects on certain types of insecticides, attention is focused on gaps in the understanding of resistance. Most resistance mechanisms consist either of a change in sensitivity of the s

Glutathione S-transferase and hydrolytic activity in a tetrachlorvinphos-resistant strain of housefly and their influence on resistance

Autor: N.W.H. Houx, F.J. Oppenoorth, L.J.T. van der Pas

Publikováno v: Pesticide Biochemistry and Physiology. 11:176-188

The high glutathione S -transferase activity found in a tetrachlorvinphos-resistant strain CH was studied. A substrain CH 3 was bred in which the gene for high transferase activity was introduced into an otherwise susceptible genome. This strain had

An unusual type of malathion-carboxylesterase in a Japanese strain of house fly

Autor: F.J. Oppenoorth, H.R. Smissaert, Maria I.Picollo de Villar, L.J.T. van der Pas

Publikováno v: Pesticide Biochemistry and Physiology. 19:60-65

It had been reported that a Japanese multiple-resistant strain of house fly, Hirokawa, had a high malathion-carboxylesterase activity as well as a normal level of esterase activity to α-naphthylacetate (NA). This is different from the situation in s

Evidence that the elevated carboxylesterase (esterase 2) in organophosphorus-resistant Myzus persicae (Sulz.) is identical with the organophosphate-hydrolyzing enzyme

Autor: F.J. Oppenoorth, A.P. Beranek

Publikováno v: Pesticide Biochemistry and Physiology. 7:16-20

An enzyme hydrolyzing methylparaoxon in vitro in an organophosphorus-resistant strain of the peach potato aphid ( Myzus persicae Sulz.) is present in the same electrophoretic fraction as a carboxylesterase (esterase 2) which has previously been shown

Insecticide metabolism and partition in isolated organs of house fly larvae and adults

Autor: L.J.T. van der Pas, F.J. Oppenoorth

Publikováno v: Pesticide Biochemistry and Physiology. 25:40-53

Isolated organs of larvae and adults of house flies were incubated in nutrient solutions to study uptake and metabolism of insecticides. Single organs were incubated in solutions of radiolabeled paraoxon, methyl-paraoxon, parathion, and tetrachlorvin
