The performance of egg traps for monitoring ovipositional activity of the navel orangeworm, Amyeloi$ transitella (Walker), is impaired by the competing attractiveness of the almond crop during the period when the almonds dehisce (hullsplit). To determine if egg traps detect the onset of second-generation moth activity, activity of navel orange worm after hull split was monitored with egg traps and blacklight traps in five commercial almond orchards during two seasons. The performance of egg traps that were painted black also was compared with that of standard, clear plastic egg traps. Although significantly more eggs were found on black traps than on standard traps, both trap types detected fairly accurately the onset of second-generation moth emergence, as measured by the black light trap catches.
