|Abstract||When larvae of Aedes aegypti (L.) infected with Romanomermis culicivorax were fed on a diet low in quantity or protein content or both, the number of postparasites that emerged from the hosts decreased and host mortality increased marginally. Parasitic development was prolonged and became asynchronous in nutritionally deprived hosts. Nematodes emerged from insects infected by more than one nematode before the remaining juveniles comprising such infections had completed parasitic development; this resulted in substantial reductions in postparasite numbers. Host development was retarded by low protein and/or reduced diets. Postparasites emerging from 2nd- and 3rd-instar mosquito larvae were reduced in size and the amount of stored nutriment compared to those recovered from hosts fed on a high protein diet ad lib. A greater proportion of the mermithids developed into males on reduced diets but not in hosts fed on low protein diets..|
