AbstractPredation experiments were conducted to identify a predator with the capacity to control the tomato russet mite, Aculops lycopersici(Massee) (Eriophyidae), in greenhouse tomato crops. The efficiency of four predatory mites species was evaluated at the individual level in the laboratory: the tydeid Homeopronematus anconai(Baker) and the phytoseiids Phytoseiulus persimilisAthias-Henriot, Amblyseius cucumerisOudemans, and A. fallacisGarman. The first three species had already been suggested as potential control agents. Predation by P. persimiliswas essentially zero on tomato russet mite, whereas H. homeopronematusfailed to develop to the adult stage when fed solely with this prey. Amblyseius cucumerisdeveloped successfully on tomato russet mite but failed to reproduce. Only A. fallacisappears to possess several of the biological attributes required to control the tomato russet mite. This species attacks all stages of the pest and displays excellent survival (.92%), adequate rate of development (6.3 days at 22 °C), and good reproductive capacity in the presence of A. lycopersici. |
