Development, breeding and behavior of Toxorhynchites (Lynchiella) haemorrhoidalis haemorrhoidalis (Fabricius, 1794) (Diptera: Culicidae) in the laboratory

Rosa Sá Gomes Ηutchings About the author

The predation, canibalism and emergence behavior of Toxorhynchites (Lynchiella) haemorrhoidalis haemorrhoidalis in the laboratory is described. The development period for each instar, under laboratory conditions, is presented for rearing under different diet, temperature and light conditions. The larvae of T. h. haemorrhoidalis, reared with fish ration, completed their development, even though they took longer to achieve adult stage. Light conditions did not influence the development period of prey feeding larvae, contrary to ration fed larvae. Low temperature prolonged the larval development period, independent of diet.
