AB  - Larvae of gypsy moth (Lymantria dispar L.) are major defoliators of deciduous forests and urban
environment. The biological means of regulation of moth population density were incorporated
along with conventional treatment in the integrative management concept. The effects of tansy
(Tanacetum vulgare L.) essential oil (EO) to gypsy moths were monitored through the effects of
residual contact and digestive toxicity on the mortality and development in the second instar
larvae, but also through the growth and feeding indices of the fourth instar larvae. Although EO
presence didn’t cause residual contact toxicity or significantly affect larval mortality, tested oil notably elongated developmental time by delaying the molting moment and reduced percentage
of molted larvae. On the other hand, EO digestion caused significant mortality in the second instar
larvae (72% compared to control, at the end of experiment). Digestion of food enriched with tansy
oil decreased the efficiency of the diet, and led to reduced mass gain, and therefore induced the
delay of the molting moment, or completely stopped molting into the third instar larvae. Besides
that, EO reduced the daily mass gain (0.06 mg mg-1 day-1 compared to 0.3 mg mg-1 day-1 in control)
and the food consumption rate (0.61 mg mg-1 day-1 compared to 1.23 mg mg-1 day-1 in control)
in the fourth instar larvae and caused decrease of the conversion rate of digested food to larvae
body mass (10.62% compared to 26.05% in control). Despite that, food assimilation rate to larvae
body mass was not significantly decreased, which moderated negative effects of EO digestion as
well as reduced food intake.
