Abstract:

Morphological and histo-pathological effects of a common broad spectrum systemic organophosphate insecticide, Phorate (O, O-Diethyl S-(ethylthio) methyl phasphoroditl) were evaluated on the integument of an epigeic earthworm, Eisenia fetida. The acute toxicity experiments were conducted by direct contact test (48 h) through a filter paper method recommended by OECD Guideline, 207. The LC50 value for 48 h was recorded and it was 20-40µl. Morphological alterations on the worm’s skin and histological observations showed coiling, curling and rupturing of body wall and formation of internal glandular cell mass and disintegration of circular and longitudinal muscles, which failed to regulate the internal coelomic pressure leading to fragmentation of body. The findings of morphological and histo-pathological studies could be applied in the environmental risk assessment of phorate.


Keywords: Histology, Phorate, OECD, Earthworm, Eisenia fetida.
