Influence of Iron on Stage Specific Life-Table and Absolute Growth Rate of Culex Quinquefasciatus
The exposure of sub lethal doses of iron salt, FeCl3 resulted in a variable increase in mortalities of various life stages
(L1-L4, pupa), adult emergence and generation morality (k-factor). On the other hand, the absolute growth rate was declined
drastically but the developmental duration of various larval stages was declined significantly in L1 and L3 instars only. Beside
toxic and adverse effects of Fe salt on survival and longevity, stress of this heavy metal was found as accelerating factor for the
early larval development.
