- Abstract
Three plant essential oils namely parsley, cumin and onion seed oil were tasted at three concentrations (0.1, 0.5 and 1 % V/V) in combination with the entomopathoginic fungi Metarhizium anisopliae var. acridum and Beauveria bassiana in laboratory against Schistocerca gregaria (Forskal) and Euprepocnemis plorans (Charpentier). Parsley oil was used at the concentration (0.1%) in combination with the two fungi at rate of 25 g spores/ha, as well as the two fungi separately at rates of 50 and 25 g spores/ha against common grasshoppers at Baharia Oasis. Laboratory results showed that parsley and cumin oils showed better effects for M. anisopliae var. acridum and B. bassiana, while onion oil caused antagonism. In the field, using Parsley oil at the concentration 0.1% in combination with the two fungi, better control was marked.
