Films based on rice flour were optimized using varying concentrations of guabiroba pulp (0?20%). After production using casting techniques, the films were subsequently characterized and compared to the control film. It was observed that the addition of guabiroba pulp enhanced the mechanical, optical, and water vapor barrier properties of the obtained films. Scanning electron microscopy and Fourier-transform infrared spectroscopy tests indicated a good dispersion and interaction of the guabiroba pulp with the rice flour polymer matrix. Guabiroba pulp can therefore be used as a reinforcing additive in edible food packaging, among other purposes. |

High dispersal of Lepidoptera larvae between non-Bt and Bt cotton plants can favour the evolution of insect resistance; however, information on host acceptance of neonates in tropical transgenic crops is scarce. Therefore, the purposes of this study were as follows: (i) to investigate the feeding behaviour of susceptible and Cry1F-resistant strains of Spodoptera frugiperda (J.E. Smith) on Bt and non-Bt cotton (Gossypium hirsutum L.) varieties and (ii) to understand the possible effects of cotton field contamination on the dispersal and infestation capacity of S. frugiperda larvae by using an individualbased model. The main results of this paper are as follows: (1) the highest post-feeding larval dispersal of the Cry1F-resistant strain occurred at an exposure time of 18?24 h; (2) via video tracking assays, we found that the least distance moved was by larvae resistant to Cry1F on non-Bt cotton; and (3) the model indicated differences in mobility capacity between Bt and non-Bt cotton. We conclude that resistant neonates exhibit sedentary behaviour. Our report represents the first findings concerning the fitness cost of larval behaviour traits of S. frugiperda associated with Cry1F resistance in Brazilian populations. |
