The study highlights the adverse effects of organophosphate compounds dichlorvos and chlorpyrifos on reproduction in Drosophila. Freshly eclosed first instar larvae of Drosophila melanogaster transgenic for hsp70 (hsp70-lacZ) Bg(9) were fed on 0.015-150.0ppb dichlorvos and chlorpyrifos mixed food. Virgin flies eclosing from the normal and contaminated food were pair-mated to examine the effect of the test chemicals on reproduction of the exposed organisms. Expression of hsp70, sex peptide (SP or Acp70A), accessory gland protein (Acp36DE) and tissue damage was examined in reproductive organs of adult fly. Exposed organisms exhibited a dose-dependent significantly reduced reproductive outcome and males were found to be more sensitive than females. Hsp70 expression was restricted only within the testis lobes of male fly while it was not induced in the ovary of the female. In concurrence with absence of hsp70 expression in the accessory glands of male fly, tissue damage was evident in them. Acp70A and Acp36DE expression were found to be significantly downregulated at the higher concentrations of the test chemicals. The study suggests that (i) dichlorvos is more deleterious to fly reproduction compared to chlorpyrifos with an adverse effect on Acp70A and Acp36DE expression required to facilitate normal reproduction; (ii) hsp70 may be used as a marker of cellular damage against dichlorvos and chlorpyrifos in Drosophila.
