| Abstract | Field data do indicate that Z. mali does have a negative impact on phytoseiid populations but that this impact is greater on some species of phytoseiids than others. In an apple system connating two phytoseiids, Typhlodromus pyri was less heavily affected by the presence of Z. mali at low prey densities than was M. occidentalis. M. occidentalis was, in fact, eventually displaced by Z. mali while the combination of T. pyri and Z. mali continued to provide satisfactory biological control of spider and apple rust mites. Laboratory trials indicate that the differential impact of Z. mali on the two phytoseiid species may be due to a difference in the oviposition locations of the phytoseiids and the foraging strategy of the stigmaeid. The use of Z. mali in biological control systems with phytoseiids at low prey densities may, therefore, be possible with appropriate management. |
