Abstract: Several annual and perennial crops are severely attacked by mites from the family Eriophyidae, Tenuipalpidae and Tetranychidae. A suitable alternative commonly used in several countries for the control of these pest mites involve the use of predatory mites in the family Phytoseiidae. The phytoseiid fauna in the Brazilian natural vegetation is very rich, but nothing is known about the biology of most of these species, as it is the case with Proprioseiopsis cannaensis (Muma). The objective of this study was to determine biological parameters of P. cannaensis fed on pest mite species such as Phyllocoptruta oleivora (Ashmead) (Eriophyidae), Brevipalpus phoenicis (Geijskes) (Tenuipalpidae) and Tetranychus urticae Koch (Tetranychidae). To enable a comparison for different food sources, one of the treatments consisted of pollen from Typha angustifolia L. The study was conducted in the laboratory at 25 ± 1ºC, 80 ± 10% RH and Photophase of 12h. Proprioseiopsis cannaensis did not complete the development when it was fed on P. oleivora. Its fecundity was very low with all other food sources (maximum of 3.3 eggs/female with pollen of T. angustifolia). The values of r_m for P. cannaensis were -0.05, -0.09 and 0.002 when fed on B. phoenicis, T. urticae and pollen respectively. The unsatisfactory results from the four types of food sources do not permit us to conclude that P. cannaensis utilizes mites from the family Eriophyidae, Tenuipalpidae, Tetranychidae or pollen from different plant species as principal sources of food in nature.
