The effect of Diablo (imidaclopride) on the survival of Branchiura sowerbyi Beddard, 1892 (Annelida: Oligochaeta)

Abstract

This study aimed at the effect of Diablo pesticide on the survival of aquatic
oligochaets Branchiura sowerbyi in the laboratory using three concentrations of the
pesticide and they are (0.5, 0.25,0.125)% and doubled the recommended and half,
respectively, and have shown that the results of the pesticide and toxic effect of a
killer the worms as the cause of loss of all the worms through (1,1.5,1.6) minutes of
exposure to concentrations prepared and respectively comparing with the controlled
group ,thus that the pesticide impact on the behavior of the worms through the
irritation and springing around itself. Moreover, the results of statistical analysis
have shown a significant inverse relationship between the concentrations pesticide
used and the time loss worms, and the value of LC50 ranged between (0.000002-
0.000003)% m/l.
