Abstract:In 1966, traps equipped with blacklight lamps and baited with 2 virgin female Manduca sexta Johannson moths per trap were tested to determine effectiveness of the combination in capturing moths from native populations. Baited and unbaited traps were arranged with 1- and 2-mile spacings in each of 2 sections, the moth populations being relatively high in 1 section and low in the other. In 1967 the area, covered by baited traps all spaced about 1 mile apart, was increased from about 3 to 16 square miles.
The number of male moths captured in traps baited with virgin females was nearly 4 times greater than the number caught in unbaited traps. Trap spacings had no apparent effect on moth captures in either baited or unbaited traps. In the section with low population, the ratio of male to female moths captured in baited traps showed a greater increase over unbaited traps than in the section with high population. Effectiveness of baited traps appeared to be slightly reduced when the area covered was increased from 3 to 16 square miles.
