Effect of granulosis virus (virotecto) as bioinsecticide on some biochemical changes in male albino rats

The objective of this study to determine the biochemical response of granulosis virus in male albino rats fed with potato treated with granulosis virus (0.15 g/Kg) against potato tuber moth in stores .It was carried out by evaluating the effect of daily feeding on treated potato for 5 weeks followed by withdrawal period for 10 days fed with normal diet on some biochemical and histological changes in kidney of male rats. A trail consists of 3 groups each one contain 18 rats, the first group fed on normal basal diet and served as control, the second group fed with 50% normal potato and 50% basal diet (potato group) and the third group fed with 50% basal diet and 50% potato treated with granulosis virus (virus group) through the experimental period. The obtained data revealed a significant reduction in final body weight and organs weight in both normal and treated potato groups. Sera collected at 2 and 5 weeks post feeding and at the end of withdrawal period, recorded significant disorders in some tested parameters. In addition, histological examination of kidney tissue showed different disorders in normal and treated groups.
