IconÒ is a water miscible type II synthetic pyrethroid insecticide based on active ingredient lambda cyhalothrin (10% w/w). It is used in Sri Lanka as an adulticidal indoor spray against malaria vector mosquitoes. The goal of this study was to assess the effects of IconÒ on pregnancy outcome of rats when exposed during early pregnancy (days 1 / 7). IconÒ was gavaged daily for 7 consecutive days in three different doses; 63, 83, or 125 mg/kg/day (active ingredient; lambda cyhalothrin; 6.3, 8.3, 12.5 mg/kg/day), respectively. Several parameters of reproduction and preand post-natal development were monitored. The results show that IconÒ is detrimental to pregnancy outcome (in terms of quantal pregnancy, number of uterine implants, implantation index and foetal deaths) but induced no detectable developmental defects. The anti-reproductive effects of IconÒ were mainly due to increased pre-implantation losses. Enhancement of post-implantation losses played a subsidiary role. These effects resulted from multiple mechanisms: maternal toxicity, stress, uterotropic activity and embryo-foetotoxicity. Further progesterone had a protective effect against IconÒ induced anti-reproductive actions. Overall, the results suggest that exposure to IconÒ during early gestation may result in a threat to pregnancy.

Lambda-cyhalothrin (LCT) is a type II pyrethroid insecticide widely used in pest management. This study was undertaken to evaluate the toxic effects of LCT on the kidneys and adrenal glands of rats after subacute exposure. Twenty-eight 6-week-old male albino <em>Rattus norvegicus</em> rats were randomly assigned to four groups. Group 1 was the control group, which received distilled water. The experimental groups 2, 3 and 4 received 20.4, 30.6 and 61.2 mg/kg body weight, respectively, of LCT, administered orally over 28 days. The effects of the insecticide on various biochemical parameters were evaluated at 14 and 28 days. Histopathological studies were carried out in the kidneys and adrenal glands at the end of the experiment. Lambda-cyhalothrin, as a pyrethroid insecticide, induced significant increases (P≤0.05) in plasma urea, creatinine, uric acid and glucose concentrations, and alanine aminotransferase and aspartate aminotransferase activities after 14 and 28 days. In the rat plasma samples after 28 days, residual concentrations of LCT 1R, cis,
