Effect of some plant extracts against the greater wax moth Galleria mellonella L.

Abstract

The present study was carried out to evaluate the biochemical effects of four plants extracts (D. stramonium L., Hyoscyamus muticus L., Nerium oleander L. and Eucalyptus camalulensis Dehn.) on the late instar larvae of the greater wax moth Galleria mellonella L. The results showed that treatment of D. stramonium L. 4% gave the maximum total mortality percentage (73.33%), while the minimum total mortality percentage was (13.33%) which recorded by N. oleander L. 4%. Biological parameters were studied under laboratory conditions, the life cycle decreased by increasing plant extract concentrations. The life cycle could be arranged in ascending order as follow: 58.33, 56.67, 62.67 and 69.00 day for the larvae treated with D. stramonium L. 4%, Sakran 4%, E. Camalulensis Dehn., and N. oleander L. 4%, respectively.
