Abstract:Further field and laboratory tests of propoxur against Hylurdretonus amllrariae Schedl show it to be a good candidate for proposed aerial application trials. High mortality was obtained in the field at dosage rates of 5.0 and 22.5 liters/ha of propoxur 20% EC but significantly less at 2.5 liter/ha. Poor mortality was recorded with a I% dust formulation. Whereas a rapid knockdown of exposed H. araucariae occurred in petri dishes, it took over 48 hours for total mortality to occur when infested branchets were sprayed. Residual life activity of pro- poxur 20% EC against the pest is probably more than 1 month but less than 3 months. There was no mortality among associated insects in the field, but in a cage trial, propoxur 20% EC caused high mortality among 6 insect species but not among 5 bird species, except for a bird species which died in both the test and control cages. Mortality among fish and insects was observed initially when a small mountain stream was contaminated with a high concentration of propoxur 20% EC, but no mortality was observed 200 m and more from the release point.
