Effect of aerial application of racemic disparlure on male trap catch and female mating success of gypsy moth (Lepidoptera: Lymantriidae)
Studies were conducted in Cecil County, Md., using racemic disparlure to disrupt mating communication of the gypsy moth, Lymantria dispar (L). Significant decreases in male trap catch and in mating success for three different female types were observed with increasing disruptant dose. Although degre...

Zusammenfassung: | Studies were conducted in Cecil County, Md., using racemic disparlure to disrupt mating communication of the gypsy moth, Lymantria dispar (L). Significant decreases in male trap catch and in mating success for three different female types were observed with increasing disruptant dose. Although degree of mating success was highly correlated for all three female types, differences among female types in slope, intercept, and linear and quadratic relationships were observed. Generally, plots having higher populations (as measured by larval counts) among replicate plots for each dose also had increased mating for all female types. |
