چکیده
In recent years, one of the goals of the urban executives and plant protection experts is to control green spaces pests using botanical pesticides. Having said that, Tuberolachnus salignus (Order: Hemiptera) is one of the most important pests of cold season observed every year in Tehran green spaces. In this research, the contact toxicity of a new botanical compound based on plant gums and two medicinal plant essential oils (Artemisia siberi Besser and Eucalyptus globulus Labill) was investigated against willow aphid Tuberolachnus salignus at Research Center of Municipality Greenery, District 17. Bioassay tests were carried out by topical and contact methods in laboratory conditions with 3 replications. After preliminary tests, different concentrations of Artemis were applied on nymphs and adults and LC50 doses were calculated after 24 h. The results showed that in topical and contact methods, LC50 doses for nymphs and adult aphids were 737 and 838 ppm and 758 and 794 ppm, respectively. Because of favourable effectiveness at low doses and high wetting ability, Artemis can be a good alternative to chemical pesticides. Moreover, chemical pesticides usage in urban green space is not rational and safe alternatives such as Artemis can help to achieve low risk pest control operations. Developing easy applied and sustainable formulation of botanicals is a necessary step in urban plant protection industry.
