“…It has been generally reported that P traps are more efficient than L traps in attracting moths early in the season when populations are low, while the inverse is true later in the flight period, when the density is at its highest level (Hendricks et al, 1973;Starratt & McLeod, 1976;Campbell et al, 1992;Mahrt et , 1987;Srivastava & Srivastava, 1989). A similar population density-trap catch relationship was also observed with respect to the total trap catches, with P traps being more efficient at low densities but not at high ones (Roach, 1975;Fletcher-Howell et al, 1983;Herbert et al, 1991).…”

The seasonal flight activity of both sexes of the eastern hemlock looper, Lambdina fiscellaria fiscellaria Guenée (Lepidoptera: Geometridae) was studied during two consecutive years in Quebec and Newfoundland, using light (L), pheromone (P) and combined light and pheromone (LP) traps. Moth density significantly affected the performance of the different traps, with P traps being more effective at low than high density. However, P trap catches decreased just prior to the onset of female captures, probably as a result of competition between traps and virgin calling females. Nearly all females caught in L and LP traps were already mated and even the first females caught had laid at least half of their egg complement. In Quebec under warm nights, the pattern of male activity occurred at different times, with peak P catches being later in the scotophase than those of L traps, but overall similar numbers of males were caught in both traps. In contrast, under cool nights, males were caught early in the night in both P and L traps, suggesting a strong competition effect between traps, although more males were caught in P than L traps overall. In Newfoundland, the pattern of male captures in L and P traps was similar at both high and low temperatures, so competition between trap types would always be high. Under these conditions P traps were more effective than L traps. Irrespective of the region, year or temperature, significantly more males were captured in LP, with the effect of L and P being additive. In both regions, females responded similarly to L and LP traps with peak activity occurring early in the night. Captures of females were lower than those of males under cool temperatures, suggesting that the temperature threshold for flight is higher for females. The use of L and P traps simultaneously and/or in combination is discussed in relation to integrated pest management programs and ecological considerations.

“…Blacklight trap data are sparse in other areas due to the maintenance and the cost to run the traps, which makes them difficult to use for widespread scouting (Mahrt et al 1987). Pheromone traps are commonly used to record cumulative moth flights, but are limited to the capture of S. albicosta males.…”

“…Black light traps were used to monitor S. albicosta moth flights and characterize phenology patterns at field sites near corn fields in four Nebraska locations over multiple years: Aurora (1981-1988 and 2000-2005) and Clay Center (1994) in southeastern NE, Concord (1981) in northeastern NE, and North Platte (1986 in central NE. Black light traps were used because they capture both males and females (Mahrt et al 1987). Traps consisted of a black light placed ~1.5m above ground level, with a metal funnel and canister below and use of a moth killing agent (Mahrt et al 1987).…”
