Interactions between Cycloneda sanguinea and the brown citrus aphid: Adult feeding and larval mortality
Environmental Entomology 14 (4), 520-522
Abstract: The number of Toxoptera citricida eaten per day by Cycloneda sanguinea varies in proportion to the densities of the aphid. Functional responses for the predator male and female adults corresponded to that of Holling's type II. C. sanguinea immatures failed to develop to the adult stage when fed either live brown citrus aphid or dry brown citrus aphid meal. However, successful development was achieved with larvae fed dry meal of the aphid Dactinotus ambrosiae (Thomas). This suggests that T. citricida is nutritionally inappropriate for or is toxic to C. sanguinea. Although adults and, initially, larvae of C. sanguinea were voracious predators of T. citricida, the lack of complete development of the larval stage would likely limit its use in pest management of the brown citrus aphid.
