The effects
of azadirachtin, a natural extract of the neem tree
Azadirachta indica A. Juss, on larval growth and feeding
activity of pine processionary moth (Thaumetopoea
pityocampa (Schiff.)) was investigated in laboratory
experiments conducted in 2007 - 2008. The organic
insecticide NeemAzal-T/S (a commercial neem preparation) was
applied as suspension in distilled water at concentration
levels of 0.3, 0.5 and 1%. Comparing with the untreated
leaves, the effect of the insecticide NeemAzal-T/S was
tested on the 10th day after treatment. The
results obtained in conducted experiments indicated that
NeemAzal-T/S was effective against T. pityocampa
larvae, significantly inhibiting larval growth and reducing
feeding activity.
