Abstract

The efficiency speed of some pesticides (Gokilaht. Solfac, Delta Fog and
Neocidol) against American cockroaches, Perip < /em>laneta americana at intervals with time
were tested. Results showed that, after 10 min. of contact treatments, Gokilaht
showed the most toxic effect against Periplaneta americana followed by Solfac, Delta
fog and Neocidol. While with contact toxicity test under laboratory condition., results
showed that. Solfac pesticide had the highest toxic effect against Periplaneta
americana
followed by Neocidol. Gokilaht and Delta-Fog pesticides, the LCso values
were 0.066. 0.8, 0.92 and 0.95 Ilglcm2 respectively.
Pesticides residues of neociodol and solgac were also determined at
intervals with time in different materials types (ceramic. thermal tiles, texture (cotton.
wool), unpainted wood and glasses) by using gas liquid chromatography.
The side effects of these insecticides on some enzymes activities
(chlolinesterase (ChE), Aspartate aminotransferase (AST), Alanine aminotransferase
(AL T), alkaline phosphatase (AP), total protein, Albumin, uric acid and Cholesterol) in
white rats were studied 24 hours and 21 days after treatments. Data reveald that
Solfac, Gokilaht and Neocidol gave a normal behaviour without any toxicity
symptoms. while Delta-fog exhibited abnormal behaviour. Also different changes in
the enzymes activities were detected during the experimental period for all pesticides
tested.
