| Abstract | ||
| Effect of the two Neem, Azadirachta indica extracts, Neem Azal F and T on fed Hylomma dromedarii (Koch) females and their fecundity under laboratory conditions was studied. Females mortality rate increased gradually as Neem extract concentration increased (i.e. 0.2 to 0.8%). The LC50 values were 0.8 and 0.6% post treatment ofNeem Azal F and T, respectively at the l I th day. Treated females laid fewer eggs than those of the control'. The concentrations 0.2, 0.4, 0.6 and 0.8% ofNeem extract decreased the percentage of hatching eggs from (46.38 to 10.56) and (35.4 to 8.42) and increased the larval mortality rate from (56.46 to 80.34) and from 87.15 to 94.53 for Neem Azal F and T, respectively. | ||
