الملخص EN

A laboratory experiment was conducted at Shambat Research Station to study the effect of Nimbecidine ® 0.03% (neem oil based) and Bacillus thuringiensis Berliner under trade name Agerin® against the second larva of P.

demodoucs on lime(Citrus aurantifolia Swingle) by using Complete Randomized Design with three replications.

Mean mortality number of second instar larvae was recorded daily until the end of experiment.

Nimbecidine 0.03% at 4.5 ml/L and 3.6 ml/L showed significantly highest mean mortality number of larva after third day of spray.

Than the untreated control, while Agerin® at 1.33 g/L and 1.66 g /L showed the same performance after four days of treatment.

To confirm the laboratory experiment results, an experiment was conducted at two different sites under nursery conditions.

The effective doses of Nimbecidine 0.03%, Agerin® and a mixture of lowest doses of each were tested in a completely randomized design with three replications.

No larva was detected at Nimbecidine 0.03% at 4.5 ml/L after two days of spray.

The results showed the potential of Nimbecidine 0.03% at 4.5 ml/L and Agerin® at 1.33 g/L to 1.66 g/L in the control of P.

demodocus Larva on lime seedlings under nursery conditions.
