Abstract

Mrežasta stjenica platane najvažniji je štetnik američke platane. Suzbijanje štetnika u urbanim područjima otežano je zbog habitusa biljke, a primjena insekticida ugrožava zdravlje ljudi i životinja. Učinkovitost prirodnih polifenola dokazana je u suzbijanju mnogih štetnika, a njihova bi primjena u suzbijanju mrežaste stjenice platane doprinijela očuvanju okoliša i zdravlja ljudi. Cilj rada bio je utvrditi učinkovitost pripravaka na bazi ekstrakta kave (koncentracije 45 g/L), standarda kofeina... More (koncentracije 45g/L), ekstrakata lišća stevije (koncentracije 6 g/L i 75 g/L), te mješavine ekstrakata kave (koncentracije 45 g/L) i stevije (koncentracije 6 g/L) u suzbijanju stjenice. Najbolji učinak iskazao je pripravak na bazi kofeina (do 80 %), a potencijalni insekticidni učinak utvrđen je kod primjene mješavine ekstrakata kave i stevije (do 75 %). Insekticidnu učinkovitost istraživanih polifenola u suzbijanju ovog štetnika potrebno je dodatno istražiti i na drugim vrstama kukaca. Less

Abstract (english)

The sycamore lace bug is the most important pest of the American sycamore. Pest control in urban areas is difficult due to the habit of the plant, and the use of insecticides endangers human and animal health. The efficacy of natural polyphenols has been demonstrated in the control of many pests, and their application in the control of the sycamore lace bug would help protect the environment and human health. The aim of this study was to determine the efficacy of preparations based on coffee... More extract (concentration 45 g/L), standard caffeine (concentration 45 g/L), stevia leaf extract (concentration 6 g/L and 75 g/L) and a mixture of coffee (concentration 45 g/L) and stevia extract (concentration 6 g/L) in pest control. The preparation based on caffeine showed the best efficacy (up to 80%), and the potential insecticidal activity was found when using mixtures of coffee and stevia extracts (up to 75%). The insecticidal efficacy of the studied polyphenols needs further investigation in other insect species. Less
