Effectiveness of different plant extracts against Galleria mellonella larvae in laboratory

Abstract

The present investigation was undertaken to study the effectiveness of different plant extracts against Galleria mellonella larvae in laboratory. Acetone prepared extracts of leaves, stem, seed, root, husk of thirteen medicinal and healthy plants were used to examine their effects on the mortality of the greater wax moth Galleria mellonella larvae in laboratory.  Results revealed that only six plant extracts prepared with leaves and stem cause mortality of wax moth. Larval mortality was highest (93.33%) with husk prepared extract of P. psyllium followed by leaf prepared extract of H. sativum (80%), Raphanus sativus (73.33%), Linum usitatissimum (66.66%) Cucurbita moschata (46.66%) and Vicia sativa (46.66%). The larval mortality with stem/root/seed prepared extract was recorded highest in Hordeum sativum (73.33%) followed by Raphanus sativus (80%), Cucurbita moschata (60%)  Linum usitatissimum (53.33%) and Vicia sativa (40%) and found significant difference with the control (0.00%). There was no mortality of larvae was found in control and other remaining plant extract. Irrespective of the different plants, highest per cent mortality (52.22%) of wax moth larvae by stem/seed/ root prepared extract followed by leaf extract (48.66). Therefore, the plant extract of different plants were found effective against Galleria mellonella larvae.
