Insecticidal and antifeedant activity of Momordica charantia aqueous extract against cutworm, Spodoptera litura(f.) (lepidoptera: noctuidae) larvae
Antifeedant activity of aqueous extract of Momordica charantia (Cucurbitaceae) leaf or commonly known as ‘peria katak’ was tested on early 4th instar larvae of Spodoptera litura. The preliminary study was carried out to investigate the effect of feeding activity on body weight of S.litura. From...

Antifeedant activity of aqueous extract of Momordica charantia
(Cucurbitaceae) leaf or commonly known as ‘peria katak’ was
tested on early 4th instar larvae of Spodoptera litura. The
preliminary study was carried out to investigate the effect of
feeding activity on body weight of S.litura. From the study, the
early 4th larval instar was fed with fresh leaves of M.
charantiaas well as fresh leaves of cabbage used as a control.
The larvae fed on M. charantia leaves showed a high percentage
value of reduction in weight, which is 91.81% after feeding at
day-7. The aqueous extract of M. charantia was then prepared
to determine the deterrent feeding activity of the larvae. The
deterrent feeding activity is count based on percentage of starvation index (Percent starvation = (C-E) / (C-S) x 100;
Where: C = Mean weight gain of control larvae within 24 hours,
E = Mean weight gain of treated larvae at each tested
concentration within 24 hours, S = Mean weight gain of starved
control larvae within 24 hours). The 100% concentration of
extracts was tested. From the experiment, the extract exhibited a
significant antifeedant activity at the LC50 levels. We found that
the extract of M. charantia has antifeedant activity against S.
litura larvae, where 100% concentration gave 57.02% of
starvation index. |
