Technical Abstract: Trap saturation, the decrease in traps’ efficiency due to accumulation of trapped insects and debris, is a problem in all insect traps but especially in sticky traps. During field tests to trap navel orangeworm males (ca. 1.5 cm wing span) delta and wing traps whose liners (sticky surface ca. 465 cm2) were not replaced captured progressively fewer moths after ca. 50-60 moths were captured. In contrast, panel traps (sticky surface ca. 14,000 cm2) continued to catch in moths in high numbers. Whether nightly moth trap catch was low or high, the large sticky traps performed well with moths distributed over the entire surface of the traps from the onset of a test, and these large traps captured up to 10-fold more moths per night than commercial traps whose trapping surface was changed nightly. The large traps’ higher catch numbers per night imply that these traps have a larger sampling radius than wing and delta traps. This large sticky trap can be readily assembled in the laboratory from common building materials. Trap color also influences trap catch of navel orangeworm males and females and should be examined further.
