| Popis: | The insect growth regulator, RO 13-5223, applied at concentrations up to 0.1% a.i., did not affect the normal development of immature stages of 2 hymenopterous parasites:Metaphycus bartletti Annecke & Mynhardt andAphytis holoxanthus DeBach, parasitoids ofSaissetia oleae (Olivier) andChrysomphalus aonidum (L.), respectively. Spraying citrus trees at the rate of 7.5 g. a.i./tree had no adverse effect on the activity of the following parasitoids:Aphytis chrysomphali (Mercet) andComperiella bifasciata Howard, an ecto- and endoparasite of the California red scale,Aonidiella aurantii Maskell, respectively;Aphytis hispanicus (Mercet) andProspaltella inquirenda Silvestri, an ecto- and endoparasite of the citrus chaff scale,Parlatoria pergandii Comstock, respectively. |
