Abstract
Zlatooka Chrysoperla carnea smatra se jednom od važnijih predatorskih vrsta za biološko suzbijanje štetnih kukaca, kako na otvorenom, tako i u zaštićenim prostorima. Za dobivanje boljih rezultata često se upotreba prirodnih neprijatelja kombinira s prirodnim insekticidima (botanički insekticidi) i derivatima nekih organizama (naturaliti). Cilj ovog istraživanja bio je utvrditi akutno i rezidualno djelovanje botaničkih insekticida i naturalita na zlatooku C. carnea. Istraživanje je provedeno u laboratorijskim uvjetima na ličinkama zlatooke koje su postavljene u petrijeve posude tretirane s pet različitih insekticida (azadiraktin, piretrin, spinosad, abamektin i cipermetrin kao standard). Očitavanje se provodilo svakih 24 sata tijekom sedam dana. Akutno djelovanje utvrđeno je nakon 24 h, a rezidualno djelovanje sedmi dan od tretiranja. Najučinkovitijim na ličinke pokazao se standardni kemijski insekticid s djelatnom tvari cipermetrin, čija je učinkovitost sedam dana od tretiranja iznosila 73,1 % te je klasificiran kao malo opasan za ličinke C. carnea. Botanički insekticidi i naturaliti pokazali su se bezopasnima za ličinke C. carnea, jer su imali vrlo slabo akutno i rezidualno djelovanje. S obzirom na rezultate, botaničke insekticide i naturalite možemo smatrati sigurnijom alternativom za upotrebu od kemijskih insekticida, kada se koriste zajedno s prirodnim neprijateljem C. carnea.
Abstract (english)
Lacewing Chrysoperla carnea is considered one of the most important predatory species for biological control of pest insects, both outdoors and in protected areas. For achieving better results, the use of natural enemies is often combined with natural insecticides (botanical insecticides) and derivatives of some organisms (naturalytes). The aim of this research was to determine the acute and residual effects of botanical insecticides and naturalytes on C. carnea. The study was conducted under laboratory conditions on larvae which were placed in petri dishes treated with five different insecticides (azadirachtin, pyrethrin, spinosad, abamectin and cypermethrin as a standard). The readings were performed every 24 hours during seven days. The acute effect was determined after 24 h, and the residual effect on the seventh day after treatment. The standard chemical insecticide with the active substance cypermethrin proved to be the most effective against larvae, with an efficiency of 73.1% seven days after treatment and was classified as slightly harmful for C. carnea larvae. Botanical insecticides and naturalytes proved to be harmless to C. carnea because of very low acute and residual activity. Given the results, botanical insecticides and naturalytes can be considered a safer alternative to chemical insecticides to use together with C. carnea against insect pests.
