Interpretive Summary: Three chemicals were found to be attractive to Navel Orangeworm (NOW) adults during field testing. Two of the three attractants captured similar numbers of moths and many more than the third attractant. Preliminary studies of dosage effects on trap capture indicate that higher dosages of better attractants captured more moths. Trapped moths in the size and shape range of NOW were at least 95% NOW. Both male and female moths were trapped, and in most tests more males than females were trapped and all trapped females were mated.

Technical Abstract: Three chemicals were found to be attractive to Navel Orangeworm (NOW) adults during field testing. Traps baited with compounds 2 and 3 captured similar numbers of moths and both captured more moths than compound 1. Preliminary studies of dosage effects on trap capture indicate that higher dosages of compounds 2 and 3 captured more moths. Most of the moths captured in the traps were NOW, and of those in the size and shape range of NOW at least 95% were NOW. Both male and female moths were trapped, and in most tests more males than females were trapped. However, all trapped females were mated, as evidenced by the presence of one or more spermatophores in their bursa copulatrix.
