Aphides affecting cultivated Plants. (I) The Carrot, Parsnip, and Willow Aphid



Aphides affecting cultivated Plants. (I) The Carrot, Parsnip, and Willow Aphid



N. Z. J. Agric, Wellington, April 20th. 50: 4, 230-231



The introduced Aphid, Cavarietta aegopodii, Scop., causes serious damage to carrots and parsnips in New Zealand during January or February, when the presence of large numbers on the leaves cause the tops to wilt and the plants to lie prone on the ground. In heavy infestations an offensive smell is given off, and the tops become sticky with honey-dew. The overwintering eggs are laid in the axils of the buds of willow and hatch when these open.
