Abstract
A chemically defined synthetic rearing medium was used to compare larval growth of Aedes aegypti with or without crude animal lecithin or synthetic dipalmitoyl lecithin. Pupal weights, adult female life spans and oviposition histories of pupae and adults derived from synthetic diet rearings and from crude culture (liver powder) rearings were also compared. Both lecithins improved larval growth rate; optimal concentrations reduced time to pupation by 2 and 1 days for animal and synthetic lecithins respectively, and animal lecithin was better tolerated by the mosquito larvae at the higher concentrations tested. Addition of crude animal lecithin to the basal synthetic rearing medium had little effect on the weights of male and female pupae, but it increased adult female life spans and improved weekly egg production. In no ease did mosquitoes from axenic rearings in synthetic media deviate greatly from limits specified by earlier workers for field‐derived mosquitoes.RÉSUMÉ: AMELIORATION DES PERFORMANCES DES ADULTES ET DES LARVES D'AEDES AEGYPTI PAR LA PRESENCE DE LECITHINE DANS LE REGIME ALIMENTAME SYNTHETIQUE DES LARVESLes développements larvaires d'Aedes aegypti out été comparés sur des Substrats alimentaires avec ou sans lecithine animale brute ou DL‐a‐dipalmitoyle lecithine synthétique.Les comparisons ont porté aussi sur les poids nymphaux, la longé‐vité et la fécondité de femelles élevées sur régime synthétique ou à partir de poudré de foie.Les deux types de lecithines améliorent le développement larvaire; les concentrations optimales des deux régimes (lecithine animale et lecithine synthétique) avancent respectivement la pupaison de 2 et 1 jour; les lecithines animale et synthétique sont tolérées par les larves respectivement jusqu'aux concentrations de 0,008 et 0,006%.L'addition de lecithine animale brute au régime contenant de la lecithine synthétique a eu peu d'effets sur les poids des nymphes mâles et femelles mais a augmenté la longévité et la fécondité hebdomadaire des femelles.Les performances des moustiques élevés sur substrat aseptique synthétique n'ont jamais été très éloignées des limites indiquées antérieurement par les travaux sur moustiques provenant de la nature.This publication has 21 references indexed in Scilit:
