The lesser date moth ( B. amydraula) is one of most important pests of hobabook and kimri stages of date fruits in south of Iran, specially in Boushehr province. The larvae feeds on emberyonic tissues of immature date fruits and cuts relation between pedicle-fruits and then dry fruits are defoliate. The chemical control of this pest, not only wasn&rsquot successfull, but also it cause ecosystemic pollution and ommits some of useful animals. However, natural enemies of this pest, were collected, identified and then application pottential of those were determined. Date fruits that were infected by this larvae were obtained weekly from 10 orchards of different zones,at the beginning of the pest activities in Dashtestan and Tangestan (Boushehr province),and then they reproduced in speciall experimental containers at laboratory. Two Hymenopter parasitoids Gonizus sp. and Bracon sp., one larval pathogen Pasteuria (=Bacillus) sp. and one spider of family Thomisidae were identified. The pottential and parasitism of them were determined. The active parasitoides, predators and bacterial pathogens on lesser date moth larvae showed a high pottential of biological pest control in Boushehr province with lowest chemical application in ecocystem.
