Imidacloprid
(1[(6-chloro-3-pyridinyl) methyl]-N-nitro-2-imi- dazolidinimine, chloronicotyl
(CAS No: 105827-78-9)), neonicotinoid insecticide, is an extensively used
insecticide for crop protection in the world wide from the last decade due to
its low soil persistence and high insecticidal activity at low application
rate. The acute and sublethaleffects ofimidacloprid on non-target organisms are
not well known on aquatic life. The aim of the present study is to determine
the histopathological effects of sublethalimidacloprid on the standard
non-target test organism, Tilapia (Oreochromisniloticus). Experiments were
conducted at two concentrations (50 and 100 mg/Limidacloprid) with two control
groups (control and control with acetone). 60 L glass aquariaswere used with
aeration. The mean weight and length of tilapia were 34.07± 1.49 g and
12.85±0.18 cm, respectively. After exposure to 24 and 96 h to
sublethalimidacloprid concentrations, the fish were sacrificed under ice
anesthesia and fixed with buffered 10% formalin. Routine histological procedures
were processedand tissue sections were stained with H&E. Following exposure
to sublethalimidacloprid caused some lesions on gill and liver tissues. There
is no significant histopathological findings were observed on the other tissues
when compared to control groups. Gill tissues showed hyperemia, epitelial
lifting, fusion of secondary lamellae and talengiectasia, whereas hyperemia and
hydropic degeneration were observed in the liver tissues.

Imidacloprid was affected on cellular level even in sublethal
concentrations
