Abstract:
The use of systemic insecticides to control the egg or the young larva of the almond wasp, Eurytoma amygdali, within the nucellus of the young almond fruit was examined. Phosphamidon was found to leave low, but very persistent residues in the seed, and rather high and persistent residues in the pericarp of the fruit. Phosphamidon and monocrotophos were applied as sprays at three different phenological dates. They did not prevent hatching. 0.03% Phosphamidon was effective in killing the larvae when applied after about 66% had hatched, but had little or no effect when applied earlier, when only 12% of the eggs had hatched, or later, 2 weeks after termination of hatch. 0.06% Phosphamidon was effective when applied at 12% hatch, but not when applied 2 weeks after the termination of hatch. 0.08% Monocrotophos was particularly effective at both application times.
