In this study, we review the wide range of alternative control methods used to this day to control the Colorado potato beetle (Leptinotarsa decemlineata Say), the biggest potato pest globally. We further categorize and highlight the advantages and disadvantages of each method by comparing them to conventional insecticides. In a second step, we point out the current knowledge about positive and negative impacts of using alternative control methods. By this, we illustrate how alternative control methods, farmers’ activities, and environmental factors (e.g., biodiversity and ecosystem health) are heavily linked in a cycle with self-reinforcing effects. In detail, the higher the acceptance of farmers to use alternative control methods, the healthier the ecosystem including the pest’s enemy biodiversity. The following decrease in pest abundance possibly increases the yield, profit, and acceptance of farmers to use less conventional and more alternative methods. Overall, we try to balance the positive and negative sides of alternative control methods and combine them with current knowledge about environmental effects. In our view, this is a fundamental task for the future, especially in times of high species loss and increasing demand for environmentally friendly agriculture and environmentally friendly products.

Mrežasta stjenica platane Corythuca ciliata Say (Hemiptera: Tingidae) značajan je štetnik platane. Stjenice sišu na listovima čime smanjuju fiziološke funkcije, izazivaju žućenje listova, a za jakog napada uzrokuju i preranu defolijaciju platana. Također su i neugodan molestant u urbanim sredinama. Suzbijanje štetnika otežano je zbog veličine krošnje i opasnosti za zdravlje ljudi i životinja uslijed primjene insekticida, stoga se sve više pozornosti pridaje ekološki prihvatljivijim mogućnostima suzbijanja. U radu je istraživana učinkovitost smanjenih doza biološkog insekticida na bazi prirodnog piretrina u suzbijanju mrežaste stjenice platane. Uz preporučenu dozu, istraživana je učinkovitost ½ doze, 1/5 doze, 1/10 doze, te 1/20 preporučene doze navedenog preparata tijekom laboratorijskog pokusa. Rezultatima je dokazana učinkovitost višestruko smanjenih doza piretrina što upućuje na visoku djelotvornost ovog ekološki povoljnijeg sredstva što je od izuzetne važnosti kod planiranja zaštite u urbanim sredinama gdje je povećana opasnost od kontaminacije ljudi i kućnih ljubimaca uslijed primjene kemijske mjere zaštite bilja.
