Abstract
The effectiveness of buprofezin against the California red scale, Aonidiella Aurantii (Maskell), and the Mediterranean black scale, Saissetia oleae (Olivier), was studied. LC50 for first and second instars of A. aurantii were 0.127 and 0.135 mg (AI)/liter and for S. oleae were 0.008 and 0.031 mg (AI)/liter, respectively. Buprofezin had a moderate effect on male pupae of A. aurantii, with an LC50 of 93 mg (AI)/liter. Females of both scales were not significantly affected by buprofezin. At 100 mg (AI)/liter, buprofezin suppressed embryogenesis of both scale species, resulting in a significant reduction in production of A. aurantii crawlers and in strong suppression of egg vitality of S. oleae. The effect on S. oleae embryogenesis was associated with length of exposure of females to buprofezin before oviposition. Buprofezin was quite persistent. The RLT50 values (residual lethal time of which potency is reduced to 50% of the original value) of 125 mg (AI)/liter under indoor and outdoor conditions were 87.9 and 33.5 d, respectively.
