VILLAR-GONZALEZ, David del; VILLANUEVA-JIMENEZ, Juan A.  and  MARTINEZ-BECERRIL, César. Neem (Azadirachta indica) ethylic ether extracts on brown rice as feeding deterrent in the control of bronzed red-eyed cowbird (Molothrus aeneus). Agrociencia [online]. 2006, vol.40, n.2, pp.197-203. ISSN 2521-9766.

Effectiveness of neem (Azadirachta indica) leaf and seed in deterring feeding of bronzed (red-eyed) cowbird (Molothrus aeneus) was determined under laboratory conditions. Brown rice grains were contaminated with ethylic ether extracts from dry neem leaves (0.0, 0.1, 0.2 and 0.4%). After evaporation of solvent, four groups of cowbirds were fed with these contaminated rice mixtures. Ethylic ether extracts of unpeeled neem seed (0.0, 0.05, 0.1 and 0.2%) were used in a second experiment. Cowbirds had lower (p≤0.05) consumption of rice contaminated with 0.1 and 0.2% neem leaf extracts and 0.2% neem seed extract, with a repellency effectiveness of 15.42, 17.16 and 19.91%, respectively.
