“…Our findings agree with Bueno et al (2009), who found that the parent parasitoid chose the host egg efficiently because it supplies food reserves for the offspring. Chlorantraniliprole's safety to T. remus may explain why it parasitizes chlorantraniliprole-treated egg masses.Though,chlorantraniliprole has potent ovicidal properties, it was found to be safe to the FAW egg masses parasitized by T. remuswhich is in affirmation with the findings of Preethaet al (2009) and Sharma (2005) who reported that chlorantraniliprole was safe and harmless to the egg parasitoid, Trichogramma chilonis. This may be due to the fact that, the biochemical changes that take place within the host egg due to parasitization might have led to the reduction in ovicidal action and ineffectiveness of chlorantraniliprole on the FAW eggs parasitized by T. remus.…”

The present study aimed to assessthe safety of insecticides and botanicals forFAW management against Telenomus remus. Laboratory investigation on the effect of botanicals / insecticides on the parasitic potential of T. remus on FAW eggs revealed maximum parasitization and parasitoid emergence from chlorantraniliprole treated eggs (97.2 and 95.4 %) followed by azadirachtin, emamectin benzoate, flubendiamide and Spinetorum. Similarly, pot culture study revealed maximum parasitization (97.0%) and parasitoid emergence (90.1%) in egg masses treated with chlorantraniliprole indicating the relative safety of chlorantraniliprole to T. remus. Chlorantraniliprole and emamectin benzoate control Fall armyworm. The foregoing experimental results show that T. remus can be a good candidate for integrated FAW management.

“…As a shortterm fix, we moved the boundaries of the computational domain far outside the region of interest, which required extrapolation of the initial topography and increased run time by 20%. In the long term, however, a transparent or absorbing boundary condition should instead be applied ͑e.g., Ehrhardt, 2001;Sharma and Imhof, 2005͒. As a side note, the time needed for one inversion run with 210 model evaluations and 2501 time steps per model was just under one day, using six IA-64 Itanium 2 processors clocked at 1.6 GHz on a SGI Altix system.…”

Geologic process models predict the geometry of geologic strata and their petrophysical properties, based on mathematical models of geological processes that affect the formation and evolution of geologic strata. Such processes include erosion, sediment transport, and deposition. The resulting forward model is typically nonlinear. Given observations and a misfit measure, one may attempt inversion of these models to estimate process parameters that yield compatible predictions. For seismostratigraphic inversion, seismic data are used as observations. We tested such an algorithm in a prograding-delta environment to examine the effect of using different seismic attributes as observations and, thus, different choices of misfit measures. The first measure, based on the degree of parallelism between seismic reflectors and modeled geologic strata, demonstrated a trade-off between geologic time and the sediment-influx rate used to parameterize the model. A second misfit measure used unwrapped seismic instantaneous phase as a crude proxy to relative geologic time, which regularized the model parameters. Then last, we combined the two measures to take advantage of their individual characteristics. For most of these inversion experiments, we obtained results that capture the geometry of the geologic strata as observed on the seismic data. With the exception of the depositional time-rate trade-off, where the same strata can be obtained in a shorter geologic interval when rates are increased, we found the inversion to be surprisingly stable, with a unique cluster of acceptable parameters, despite the nonlinearity of the geologic forward model.
