Аннотация: In field studies in the Russian Far East, five types of illuminating devices were evaluated for attracting adult gypsy moth, Lymantria dispar (L.), pink gypsy moth, L. mathura Moore, and nun moth, L. monacha (L.). Our objective was to determine if light from commercial lamps suited to out-of-doors floodlighting could be modified to reduce their attractiveness to moths without a reduction of illumination. During 17 nights of tests, fluorescent blacklight lamps captured significantly more adults than either phosphor mercury or high-pressure sodium lamps, Captures were slightly higher for phosphor mercury than high-pressure sodium lamps but both were unattractive to all three lymantriids after the addition of filters that blocked spectral emissions <480 nm. Daily temporal periodicity, based on adult captures at lights, resulted in distinct activity patterns for the three lymantriids. Peak activity for L. dispar was between 2300 and 0100 hours; for L. mathura, 0100-0300 hours; and 0300-0500 hours for L. monacha. Temporal activity patterns suggest that L. dispar and L. monacha possess nonoverlapping diel rhythms, whereas L. mathura overlaps broadly with both L. dispar and L. monacha.

Аннотация: Male Asian gypsy moths, Lymantria dispar (L.), were attracted to synthetic pheromone (cis-7R,8S-epoxy-2-methyloctadecane) in the Russian Far East, Central Siberia, and Germany, where this strain has recently been detected. A bimodal pattern of attraction was evident at all 3 sites. One peak of attraction was in early to midafternoon, with a 2nd, usually smaller peak, following sunset. Temperature modulated attraction: warm daytime temperatures increased catch, whereas low nighttime temperatures generally suppressed or eliminated attraction. However, the surge of male attraction to pheromone in the hour after sunset seemed unaffected by falling temperatures. As average temperatures at the 3 sites decreased, the daytime peak of male activity progressively shifted to later in the afternoon. Female eclosion in Germany also followed a bimodal pattern, with a major midmorning to midday peak of emergence and a 2nd, smaller peak, in the afternoon. The timing of male attraction allowed coordination of the ranging flight of the male with the availability of emerging and pheromone-emitting females. The congruence in daily activity patterns suggest that the timing of mating would not be a barrier to the hybridization of the Asian, European, and North American strains of this lymantriid in new areas of sympatry.
