Insecticide effect of pennyroyal and rosemary essential oils on the rice weevil

Abstract

The article provides data on distribution, biological features, long-term population dynamics and modern conditions of the heath butterfly Coenonympha oedippus (Fabricius, 1787) on the territory of Belorussia. In the Belorussian Polesie region, there is quite dense network of large settlements of this species on large bog massifs. The species is very sensitive to overgrowing of the habitats by bushes and reeds caused by the drop of the groundwater level in the bogs due to the water drainage by land reclamation systems and the climate warming. The overgrowing of the bogs has significantly accelerated in the last decades when they have been no longer used for mowing. In the same time, the fight against bogs bushing by burning vegetation and mechanized mowing is a concern for the well-being of the settlements of C. oedippus
