Evaluation of two Neem seed kernel extracts against Liriomyza trifolii (Burg.) (Dipt. Agromyzidae)
Anzeiger für Schädlingskunde, Pflanzenschutz, Umweltschutz 68 (2), 39-41
Abstract: Laboratory evaluation of Neem Azal-S and Margosan-O was carried out against the adult and larvae of Liriomyza trifolii Burgess. The feeding deterrent activity of both compounds was significantly realized against the adults particularly at high concentrations which lasted for 5 days after treatment. Both formulations also deterred the females from laying eggs and the percentage of oviposition deterrent index (ODI) reached 80.7 and 52.6 for Neem Azal-S and Margosan-O (2%), respectively.
Post infestation treatment of bean seedlings containing 3rd instar larvae indicated that the toxic action of the tested extracts was quite limited. However, different percentages of malformed pupae were obtained. The sex ratio between the resulting adults was nearly unaffected with the exception of individuals whose larvae were treated with 2% Neem Azal-S where all the resulting progenies were females.
