Abstract

Bioactivity of Melia azedarach L. was tested against diamondback moth (DBM), Plutella xylostella L. in the laboratory. The adult of DBM laid significantly lesser number (upto 71%) of eggs on the surfaces treated with methanolic extracts of M. azedarach than on those treated with solvent only. When larvae derived from above eggs were reared on fresh food, the mortality in the larval stage was upto 22.8% and that in pupal stage was upto 29.6%. The methanolic extracts also reduced feeding among the larvae significantly, when methanolic extract-treated food was offered to second instar larvae in a different set of experiment, thus, indicating an antifeedant effect.

Résumé

L'activité biologique de Mélia azedarach L. a été mise en preuve centre le diamondback moth (DBM), Plutella xylostella L. dans le laboratoire. Les adultes de DBM ont pondu de facon claire un moins petit nombre d'oeufs (jusqu'à 71%) sur les surfaces traités avec les extraits métanoliques de M. azedarach que sur ceux traités avec dissolvants seulement. Quand les larvae derivés de les-dits oeufs étaient élevés sur la nourriture fraîche, la mortalité à l'étape larval était jusqu'à 22.8 pour cent et que à l'étape pupal, c'était jusqu'à 29.6 pour cent. La malformation dans les adules était jusq'à 17.7 pour cent. Les extraits métanoliques ont réduit aussi de traitée avec l'extrait métanolique était offerte aux larvae au deuxiéme étape dans le différent ensemble d'expérience: donc indiquant un effect antinourrissant.
