As phytoseiid species differ widely in chaetotaxy, as well as in their ability to cope with complex webs, this hypothesis was tested by studying relations between these two variables. In this paper we develop a simple method to quantify the degree to which the soma is protected from contact with the silk and apply it to phytoseiid species for which behavioural performance in the web is known from the literature. It is found that the better protected species experience less hinder from complex webs, such as produced byTetranychus spp. Moreover, they appear to be more successful in exterminating local populations ofTetranychus spp. Thus, setal patterns in the Phytoseiidae may well be a good indicator for selecting candidates for biological control ofTetranychus spp. Finally, we propose a parsimonious scenario for the evolution of dorsal chaetotaxy in the Phytoseiidae.
