The ecology of Melangyna viridiceps and Simosyrphus grandicornis (Diptera : Syrphidae) and their impact on populations of the rose aphid, Macrosiphum rosae

Soleyman-Nezhadiyan, Ebrahim. January 1996 (has links) (PDF)
Bibliography: leaves 213-233. This thesis studies the influence of the two common syrphid species on populations of rose aphids in rose gardens in Adelaide. The study determines whether the provision of attractive flowers increases the suppressive effect of syrphids on rose aphids and analyses some ecological and biological aspects of two syrphid species -- Melangyana viridiceps (Macquart) and Simosyrphus grandicornis (Macquart) -- in a Mediteranean climate to obtain a better understanding of their biological control potential.
