Effects of Three Essential Oils and /or Gamma Irradiation on the Greater Wax Moth, Galleria Mellonella

Abstract

The journal of Toxicology and pest control is one of the series issued twice by the Egyptian Academic Journal of Biological Sciences, and is devoted to publication of original papers related to the interaction between insects and their environment. The goal of the journal is to advance the scientific understanding of mechanisms of toxicity. Emphasis will be placed on toxic effects observed at relevant exposures, which have direct impact on safety evaluation and risk assessment. The journal therefore welcomes papers on biology ranging from molecular and cell biology, biochemistry and physiology to ecology and environment, also systematics, microbiology, toxicology, hydrobiology, radiobiology and biotechnology. www.eajbs.eg.net Provided for non-commercial research and education use.

Metarhizium anisoplia was found No mortality observed at the highest concentration (4g/L) and the lowest tested concentration while the recommended concentration recorded mortality (0.1333±0.0908%) of B. brevicornis adult. While The recommended concentration (2g/L) of B. bassiana induced no mortality among the adult parasitoids while its highest tested concentration (4g/L) and the lowest concentration (1g/L) gave mortality (0.0667±.06667%) and (0.1333±0.0908%) respectively.

Influence of Some Honey Bee Products and Plant Oils on the Greater Wax Moth, Galleria mellonella L. (Lepidoptera: Pyralidae)

“…Also, clove oil differed significantly from other oils. Elbarky et al (2015) studied the efficacy of some essential oils viz., peppermint (Mentha piperita L.), geranium (Pelargonium graveolens L.) and basil, O. basilicum, using four concentrations of each oil (0.625, 1.25, 2.50 and 5.0%) against the fourth instar larvae of G. mellonella. They found that basil oil, O. basilicum scored the highest larval mortality (100%), followed by M. piperita (67%), then P. graveolens (50%) at a concentration of 5% after 96 hours of treatment.…”

Evaluation of some Essential Oils Against Wax Moth Larvae (Lepedoptera: Galleria mellonllaL.) and Adult Honeybee Workers (Hymenoptera: Apis mellifera L)

“…Sanad and Mohanny (2015) sprayed 4% clove and mint extract on new combs and found that the spray with clove extract reduced the wax moth's life cycle to 42.9 days while untreated combs was 72.0 days. in addition, Elbarky et al (2015) found that the essential oils increased the larval and pulpal periods and decreased pupation and percentage of adult emergence. Ncibi et al (2021) investigated the efficacy of natural products that were discovered to be safe for adult honeybees while effectively controlling fourth instar wax moth larvae.…”

“…Fourth instar larvae of the G. mellonella treated with Menthapiperita, Pelargonium graveolens L. and Ocimumbasilicum L. decrease pupation and percentage of adult emergence and extended the larval-pupal periods. In terms of mortality, O. basilicum is the most active, followed by M. piperita and finally, P. graveolens (Elbarky et al 2015). The oils of five plants (neem, cedar, clove, peppermint, and karang) and one extract (neem seed kernel) were tested at various concentrations and exhibited varying degrees of activity against the larvae of G. mellonella.…”
