EUROPEAN JOURNAL OF ENVIRONMENTAL SCIENCES
The European Journal of Environmental Sciences offers a mixture of original peer-reviewed research papers, which bring you some of the most exciting developments in environmental sciences in the broadest sense, often with an inter- or trans-disciplinary perspective, focused on the European problems. The journal also includes critical reviews on topical issues, and overviews of the status of environmental protection in particular regions or countries. The journal covers a broad range of topics, including direct or indirect interactions between abiotic or biotic components of the environment, interactions of environment with human society, or environmental sustainability.

abstract

This study aimed to determine the percentage infestation and population parameters of the green peach aphid Myzus persicae under laboratory conditions and evaluate the effect of aqueous extracts of three different plants (pot marigold: Calendula officinalis, mint: Mentha viridis and rosemary: Salvia rosmarinus) on the mortality of this aphid. Extracts of these plants were used at three concentrations (C1 = 15%, C2 = 30% and C2 = 45%). Results indicate a percentage infestation of 76.9 ± 9.4%, a mean relative growth rate of 0.062 ± 0.007 and generation time of 11.12 ± 1.42 days. All treatments reduced the numbers of aphids and statistically significantly reduced the number (α < 0.01) recorded after treatment with C1, C2 and C3 of each extract. C. officinalis extract was more effective than those of M. viridis and S. rosmarinus. The highest mortality (69.82 ± 5.23%) and efficacy (61.71 ± 4.46%) were recorded for the C3 of aqueous extract of C. officinalis, whereas the lowest mortality (38.24 ± 2.42%) and efficacy (32.41 ± 1.23%) were recorded for the C1 of extract of M. viridis. The data provided indicate that aqueous extracts of C. officinalis, M. viridis and S. rosmarinus have an insecticidal effect on M. persicae and can be integrated into a pest management strategy to reduce M. persicae abundance on pepper plants.
