摘要： Introduction. The rapid development of the nanotechnology industry opens new perspectives for modern crop protection strategies. This review summarizes and discusses the use of polymers as nanocarriers of insecticides. They are expected to ensure a higher level of protection for humans and the environment, while ensuring good efficacy of the active ingredient. Literature. Some of the synthetic polymers (including polyethylene glycol, polylactic acid, polycaprolactone and polyhydroxybutyrate), which are widely used in pharmaceutical or cosmetic areas, can be employed as insecticide carriers. But natural polymers (including chitosan, alginate, cellulose, starch and cyclodextrins) are receiving increasing attention because of their environment-friendly properties. The polymeric materials can be prepared in various types of tridimensional structures, among which nanocapsule, nanosphere, micelle, nanogel and nanofiber are the most common for the delivery of the active ingredient. The environmental risks of polymer-based nanoinsecticides are highlighted, together with the main challenges that must be solved before future marketing. These challenges include the reduction of their production cost and assessment of their performance, especially at the field level. New protocols for characterizing, detecting and quantifying are also urgently required. Conclusions. Polymer-based nanoformulations appear to be promising for target release of active ingredients while reducing excess runoff. In order to facilitate the development of new beneficial products, collaboration among countries around the world is required.
