Contribution to the study of reproduction in diaspine coccinellids. I. The influence of laboratory rearing and of delayed mating on the fecundity and sex ratio of Chrysomphalus ficus Ashmead (Homoptera-Diaspididae)



Contribution to the study of reproduction in diaspine coccinellids. I. The influence of laboratory rearing and of delayed mating on the fecundity and sex ratio of Chrysomphalus ficus Ashmead (Homoptera-Diaspididae)



Annales de la Societe Entomologique de France 17(2): 157-170



When the reproduction of Chrysomphalus aonidum (L.) (ficus Ashm.) was studied in the laboratory under optimum conditions of temperature and relative humidity but on watermelon or squash instead of its natural food-plant in the field (citrus), the females produced 61-438 progeny each (average 240, as compared with an average of about 100 on citrus in the field) and the total oviposition period was prolonged (an average of 48 days, as compared with 30 days).
