The effect of the new mitecide of the class of Ketoenoles (spirodiclofen) was evaluated on the natural enemies in citrus orchard. The experiment was carried out in field conditions in São Paulo/Brazil, from January to March 2002. The design was randomized blocks. Each plot consisted of 10 citrus trees, variety Pera. The treatments consisted of the miticides spirodiclofen at the doses of 4.8, 6.0 and 7.2 g of a.i./100 L of water and azocyclotin at the dose of 25 g of a.i./100 L of water and control. The application was made through a spray gun coupled to the tractor. The evaluations were made until 45 days after the application, through the method of spraying of knock down insecticides and placement of cloth sheets under the plants for the count of the fallen natural enemies on the cloth. For predators mites pocket lens was used in the counts. Spirodiclofen caused inferior mortality to 20% for spiders, ants and ladybugs (Cycloneda sanguinea) and mortality of 60% for predators mite (Euseius concordis) until 8 days after the spraying. After 20 days of spraying the populations of predators mite were reestablished.
