CARRIER MATERIALS FOR MOSQUITO-LARVAE KILLING PESTICIDES, MOSQUITO-LARVAE KILLING PRODUCTS AND METHOD OF MANUFACTURING THE SAME

摘要

The subjects of the present invention are carrier materials for mosquito-larvae killing pesticides (carrier composites), and mosquito-larvae killing products containing these carrier composites and a known larvicide (larvicide composites) and procedures of their manufacture. The carrier composites, which have lower density than the density of water, comprising one or more hydrulic binder, preferably gypsum or cement or their mixtures, containing one or more foamed aluminosilicate, preferably pumicite or perlite or their mixtures, containing one or more modified polysaccharide, preferably modified starch, modified cereal flour, carboxymethyl cellulose, or (C1-2)alkyl-hydroxy-(C1-2)alkyl-cellulose derivatives, and containing both of opened and closed air pores. The larvicide composites containing the abovementioned carrier composites and one ore more biological or chemical larvicide, feeding attractant(s) or an other attractant to call the female mosquitoes to lay eggs. Preparation methods are relating to manufacturing the carrier composites and larvicide composites.
