The spider mite, Tetranychus urticae Koch is a serious pest of economically important plants in closed and open area worldwide. The spider mite resistance to acaricide plays a major role in the failure of the chemical control method. Thus, the aim of the current study was to evaluate the efficacy of two acaricides, abamectin and propargite, against two populations (strains) of the spider mite. Results showed that LC50s of the abamectin against susceptible and resistant strains of the spider mite were 0.1 and 2730?ppm, respectively. Whilst LC50s of the propargite against susceptible and resistant strains of the spider mite were 55 and 7199?ppm, respectively. Resistance ratio (RR) calculated as the ratio of resistance LC50/susceptible LC50 showed that RR for abamectin and propargite was 20285 and 130, respectively. The enzyme assay results showed that three mechanisms of MFO, GST and EST are involved in the abamectin resistance of the spider mite. In gel assays, when α-naphthyl acetate was used as substrate, three bands appeared in the gel in which bands E2 and E3 were major bands and E1 was a minor band confirming that α-naphthyl acetate was a better substrate for general esterase activity in the spider mite whereas β-acetate when used for esterase activity, only two faint bands (E1 and E2) were observed. The order of their involvement in the abamectin resistance is EST?>?MFO?>?GST. 相似文献

It is hypothesized that Capoeta fusca might display specific life‐history traits that differ from other species of this genus. To test this hypothesis a total of 354 specimens of C. fusca (listed by ICUN in the category DD = data deficient) were caught in the Qanat of Shadmehr (a well‐known active man‐made water well system in eastern Iran) on a monthly basis to cover fully the reproductive season from April to October 2007. Based on opercula readings the maximum ages of the population were 5+ years for both sexes. Sizes ranged from 57 to 190 mm total length (weight 2.14–84.76 g). Length‐weight relationship implied that the growth was negatively allometric for males and isometric for females. The von Bertalanffy growth model was estimated as Lt=18.74(1‐e?0.33(t+0.473)) and Lt=22.35(1‐e?0.32(t+0.333)) for males and females, respectively. Sex ratio was 1 : 2.42 in favour of females. The GSI indicated that reproduction of the fish in the qanat system occurred between May and August, with the highest average value of 6.12 for males in June and 9.55 for females in July. Oocyte diameters ranged from 0.30 to 2.05 mm, with a mean value of 0.92 mm. Absolute fecundity ranged between 506 and 22 800 eggs, with a mean of 4961 eggs. Fecundity relative to total weight fluctuated from 34 to 583, with a mean value of 133 eggs per g. Absolute fecundity and oocyte diameter to fish size (length and weight) were significantly correlated. 相似文献

S100B, a calcium-binding protein of the EF-hand type exerts both intracellular and extracellular functions. S100B is induced in the myocardium of human subjects and an experimental rat model following myocardial infarction. Forced expression of S100B in neonatal rat myocyte cultures, and high level expression of S100B in transgenic mice hearts and aortic smooth muscle cells inhibit cardiac hypertrophy and the associated phenotype, arterial smooth muscle proliferation, respectively, but demonstrate increased apoptosis following α1-adrenergic stimulation or myocardial infarction. Knocking out S100B, augmented hypertrophy, decreased apoptosis and preserved cardiac function following myocardial infarction. S100B induces apoptosis by an extracellular mechanism by interacting with the receptor for advanced glycation end products and activating ERK1/2 and p53 signaling. The intracellular, and extracellular, roles of S100B are attractive therapeutic targets for the treatment of both cardiac and vascular disease. 相似文献

Stable crystalline phosphorus ylides were obtained in excellent yields from the 1:1:1 addition reaction between triphenylphosphine (TPP) and dialkyl acetylenedicarboxylates, in the presence of NH-acids, such as benzhydrazide. To determine the kinetic parameters of the reactions, they were monitored by UV spectrophotometery. The second order fits were automatically drawn and the values of the second order rate constant (k2) were calculated using standard equations within the program. At the temperature range studied the dependence of the second order rate constant (Ln k2) on reciprocal temperature was compatible with Arrhenius equation. This provided the relevant plots to calculate the activation energy of all reactions. Furthermore, useful information were obtained from studies of the effect of solvent, structure of reactants (different alkyl groups within the dialkyl acetylenedicarboxylates) and also concentration of reactants on the rate of reactions. On the basis of experimental data the proposed mechanism was confirmed according to the obtained results and a steady state approximation and the first step (k2) and third (k3) steps of the reactions were recognized as the rate determining steps, respectively. In addition, three speculative proposed mechanisms were theoretically investigated using quantum mechanical calculation. The results, arising from the second and third speculative mechanisms, were far from the experimental data. Nevertheless, there was a good agreement between the theoretical kinetic data, emerge from the first speculative mechanism, and experimental kinetic data of proposed mechanism. Figure
