The application of beneficial organisms to protected crops requires substantial manpower and obliges operators to remain for long periods in a hot and humid environment that leads to discomfort and fatigue. Mechanisation of this operation could reduce the distribution time with subsequent benefits for the health and safety of workers. A prototype distribution system for beneficial arthropods that could increase labour productivity and distribution quality on protected crops was developed. Experiments were conducted to assess the efficiency of the mechanical distribution system and its effect on the distributed organisms. Releases of the predatory mites Phytoseiulus persimilis and Amblyseius swirskii were tested in the laboratory. The release quality was verified through evaluation of distribution patterns and the effects on the viability and fecundity of both beneficial arthropods. The prototype was shown to properly perform the release without compromising the quality and biological traits of either species.

Abstract

The application of beneficial organisms to protected crops requires substantial manpower and obliges operators to remain for long periods in a hot and humid environment that leads to discomfort and fatigue. Mechanisation of this operation could reduce the distribution time with subsequent benefits for the health and safety of workers. A prototype distribution system for beneficial arthropods that could increase labour productivity and distribution quality on protected crops was developed. Experiments were conducted to assess the efficiency of the mechanical distribution system and its effect on the distributed organisms. Releases of the predatory mites Phytoseiulus persimilis and Amblyseius swirskii were tested in the laboratory. The release quality was verified through evaluation of distribution patterns and the effects on the viability and fecundity of both beneficial arthropods. The prototype was shown to properly perform the release without compromising the quality and biological traits of either species.
