- Abstract
Diaphorina citri is one of the most important pests in citrus orchards and is associated with the transmission of Huanglongbing (HLB), a disease caused by the bacterium Candidatus Liberibacter asiaticus on citrus. Currently, the use of chemical insecticides is the most common control strategy for controlling D. citri; however, other alternatives such as the use of mineral oils have been considered. Based on this, we studied the repellence and oviposition inhibition activity by the commercial mineral oils Akaroil®, Anasef - T®, Saf-T - Side® and Stylet Oil® on D. citri. The repellency was determined by exposing adults to previously treated orange leaves with different concentrations of mineral oils and the inhibition of oviposition by the residual application method. All tested oils caused significant = 90 % repellent activity to 35 mg/mL, however, this decreased to concentrations below 10 mg/mL. The greatest repellent activity was achieved by the Saf-T-Side oil (RC50 = 0.14 mg/mL), followed by Anasef-T, Akaroil and Stylet Oil, with CR50 of 1.33, 1.92, 3.32 mg/mL, respectively. Doses as low as 1 mg/mL were enough to inhibit oviposition in up to 90 % in all tested oils. We conclude that the activity of mineral oils should be validated under field conditions to determine if they represent a useful tool within D. citri integrated management.
