TL;DR: None of the observed mechanisms explained the loss of susceptibility of populations to chlorpyrifos-ethyl, and no significant correlation was detected between resistance to deltamethrin and the presence of the kdr mutation.
Abstract: Only a few of the registered insecticides against Cydia pomonella L. are still effective in areas where insecticide resistance has emerged in this pest. Resistance mechanisms are multiple, and their lone or cumulative effects in a single population are not completely understood. A detailed estimation of resistance spectrum is still required to define the suitable insecticides to use against a given population. The efficacy of ten insecticides was therefore investigated together with the resistance mechanisms expressed in four laboratory strains and 47 field populations of C. pomonella from five countries. Bioassays were performed using topical applications of diagnostic concentrations on diapausing larvae, and resistance mechanisms were analysed on adults emerging from control insects. All populations exhibited a reduced susceptibility to at least one insecticide when compared with the susceptible laboratory strain. Cross-resistances were observed between azinphos-methyl or phosalone and more recent compounds such as spinosad and thiacloprid. Resistances to azinphos-methyl, diflubenzuron, spinosad, tebufenozide and thiacloprid were significantly correlated with mixed-function oxidase activity, while increased glutathione-S-transferase and reduced non-specific esterase activities were correlated with resistance to azinphos-methyl and emamectin, respectively. Conversely, resistances to azinphos-methyl, tebufenozide and thiacloprid were negatively correlated with increased esterase activity. None of the observed mechanisms explained the loss of susceptibility of populations to chlorpyrifos-ethyl, and no significant correlation was detected between resistance to deltamethrin and the presence of the kdr mutation. The suitability of such non-target instars to monitor insecticide resistance in field populations is discussed.

TL;DR: A magnetic metal-organic framework composite was synthesized and used as an adsorbent for magnetic solid-phase extraction (MSPE) of some organophosphorus pesticides (phosalone, chlorpyrifos and, profenofos) in rice and environmental water samples.

TL;DR: The simultaneous resistance to several classes of insecticides in these codling moth populations suggests that the implementation of a rotation program to delay resistance development will be difficult, and points to the need for improving alternative control methods such as microbiological insecticides or mating disruption.
Abstract: Strains of codling moth, Cydia pomonella (L.), were collected from 3 orchards in southeastern France where different strategies of chemical control had failed. Males were mated with females of a susceptible laboratory strain and the progeny were maintained for 7-9 generations on artificial diet treated with deltamethrin, dif1ubenzuron, or a mixture of dif1ubenzuron and phosalone. These insecticides were choosen to prolong the selection pressure to which each had previously been exposed in the field. Susceptibility to these compounds and to azinphosmethyl were evaluated on newly hatched larvae every 2nd generation and compared with a susceptible laboratory strain. Resistance to diflubenzuron, deltamethrin, and phosalone occurred in the strain obtained from the orchard protected mainly with pyrethroids during the last 5 yr. Selecting this strain with deltamethrin for 7 generations resulted in a 96-,6- and 3-fold increase in the resistance to diflubenzuron, deltamethrin, and phosalone, respectively. This reveals a cross-resistance to these different insecticides in this selected strain, which also exhibited a resistance to teflubenzuron, tebufenozide, bifenthrin, and lambda-cyalothtin. Selection with diflubenzuron also resulted in a high resistance to diflubenzuron but a lower resistance to pyrethroids compared with the strain selected with deltamethrin. A decreased efficacy of azinphos methyl was observed on the 3 selected strains. The simultaneous resistance to several classes of insecticides in these codling moth populations suggests that the implementation of a rotation program to delay resistance development will be difficult, and points to the need for improving alternative control methods such as microbiological insecticides or mating disruption.

TL;DR: It is suggested that ROS may not involve in the toxic effects of the pesticidal use of phosalone in low concentrations.

TL;DR: In this article, the fate of the residues of benalaxyl, dimethoate, iprodione, metalaxyl and phosalone in sunlight and oven raisin processing was studied.
Abstract: The fate of the residues of benalaxyl, dimethoate, iprodione, metalaxyl, phosalone, procymidone, and vinclozolin in sunlight and oven raisin processing was studied. The drying process caused a fruit concentration factor of 4, while the decreases in residue with the two drying processes were different for the different pesticides. In sunlight-drying the residue level in the raisins was identical to that in the fresh fruits for benalaxyl, metalaxyl, and phosalone, whereas it was higher for iprodione (1.6) and lower for vinclozolin and dimethoate (one-third and one-fifth, respectively). The oven-drying process was preceded by washing, which caused residue decreases for iprodione and procymidone of 57 and 41%, respectively, whereas no decrease was observed in all of the other pesticides. During oven-drying pesticide residues in raisins with respect to fresh fruits showed an increase of 2.7 for phosalone, the same values for benalaxyl, metalaxyl, and procymidone, and lower values for vinclozolin and dimethoate...
