Dört farklı uçucu yağın düşük sıcaklıkta Değirmen güvesi Ephestia kuehniella Zeller (Lepidoptera: Pyralidae)'nın farklı dönemlerine karşı fümigant toksisitesi.

Bioproducts are defined as the derivatives obtained from plant components, living organisms such as fungi, bacteria, nematodes, and used as biological substances against agricultural pests and diseases. Essential oils, which are easy to obtain and can be decomposed rapidly because of their volatile property without leaving residues in the environment, are considered as alternatives to synthetic chemicals. In this study, fumigant toxicity of essential oils of four different plants [coriander (Coriandrum sativum L.), sage (Salvia officinalis L.), lavender (Lavandula angustifolia Mill.), and mint (Mentha spicata L.)] were tested against two different developmental stages of Mediterranean flour moth Ephestia kuehniella Zeller (Lepidoptera: Pyralidae). Sage and coriander essential oils were found as the most effective oils to the larval stage of E. kuehniella during 3 experimental day, respectively 96% and 98%. In egg bioassays, lavender and coriander essential oils showed 98% fumigant efficacy. In addition, even the lowest doses of those two oils were able to prevent hatching of eggs. The study results suggested that environmentally friendly essential oils were promising substances in the control of the pest as well. [ABSTRACT FROM AUTHOR]
