Nanotechnology-based Pest Control
Given the development of nanotechnology within numerous scientific disciplines, it is likely that nanoscale products have been and will be used for agricultural, vector, and urban pest control prior to a complete evaluation of exposure and risk. Significant differences may exist between nanotechnology-based pesticides (NBPs) and conventional pesticides, primarily due to size and surface charact...
متن کاملInsect Pest Control
In October 2004 the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture celebrated 40 years of existence. The creation in October 1964 of this Division, which includes the Insect Pest Control Subprogramme, marked the beginning of what is certainly a unique and arguably the best example of inter-agency cooperation within the whole UN family. The goal was to join the talents and...
متن کاملOptimal Control in Discrete Pest Control Models
We use discrete time models to represent the dynamics of two interacting populations, a “valuable” population and a “pest” population. We investigate optimal control in the form of decreasing the growth rate of the “pest” population with the goal of maximizing the “valuable” population while minimizing the cost of the control. We compare different types of growth functions for the “valuable” po...
