Effect of Aging on Three Lures Used for Monitoring Ceratitis capitata (Diptera: Tephritidae): Release Rate, Volatile Composition, and Fly Recaptures.

Prevention and control programs for Ceratitis capitata require a large supply of lures and traps for use in established trapping networks and mass-trapping suppression measures. The main lures currently used are: Trimedure (TML), three-component Biolure (BL), and Ceratrap (CT). The aim of this study was to determine the release rates of these lures, the chemical composition of their volatiles, and how these parameters change with exposure time.

Universal features of amorphous plasticity.

Plastic yielding of amorphous solids occurs by power-law distributed deformation avalanches whose universality is still debated. Experiments and molecular dynamics simulations are hampered by limited statistical samples, and although existing stochastic models give precise exponents, they require strong assumptions about fixed deformation directions, at odds with the statistical isotropy of amorphous materials. Here, we introduce a fully tensorial, stochastic mesoscale model for amorphous plasticity that links the statistical physics of plastic yielding to engineering mechanics.
