Effects of neem seed extract on feeding frequency of Nezara viridula L. (Hemiptera: Pentatomidae) on pecan nuts
Journal of the Australian Entomological Society 34 (3), 221-223
Abstract: Different concentrations of neem seed extract, containing azadirachtin, were found to significantly decrease the number of feeding sites by the green vegetable bug, Nezara viridula, on pecan nuts. Application of this extract to nuts decreased the feeding scars on nuts from 6.6 per bug per 24 h to 1.9 per bug per 24 h. This decrease was independent of azadirachtin concentration suggesting that only low application rates of this substance may be necessary to significantly reduce the damage done by this insect in pecan orchards.
