Abstract
The effect or neem seed kernel powder on larvae and adults of Tribolium costoneum was studied. The LC50 for T. Costoneum larvae was 2.99%, 1.88%. 1.36, and 0.54% alter 24 hours, 48 hours, 120-10urS, and 3M) hours respectively. The LC50 for the adults after one month was 0.622% and the LC50 was 6.41% Thirty days old Bovan chicks were fed on 0.5% and 15% of neem seed powder so as to study its effect on body weight and histopathological picture, There was an increase in body weight for the chicks that were red on 0.5% and 15% in comparison with the control chicks. The histopathological changes vary from haemorrhage and/or congestion of liver, kidney and brain cells to degeneration and necrosis of these cells. Dipping eggs of Argus persicus in different concentration of neem seed kernel oil and neem seed kernel water extract was found to decrease the hatchability The packet test was used to detect the mortality or Argus persicus larvae, The LC50 for the larvae was round to be 2.7% for neem oil extract and 12.39% for neem water extract. Thirty days old Bovan chicks were dipped into 0.5% and 15%of the previous solutions twice a week. Decreascs in weight gain were noticed for both solutions in comparison to the control. Histopathological changes were manifested in congestion and/or haemorrage of liver cells for neem seed kernel water extract for neem oil the liver cells showed hyperemea, cell infiltration while the kidney and brain cells showed congestion necrosis and fatty degeneration of the cerebellum.
