130 Food Plants of Aphis rumicis 



A few small isolated colonies present on the veins beneath the leaves of 

 the Rumex plants, but very few in numbers. One Rumex plant which 

 is producing a taU flowering head has a number of colonies on it. 



The other plants not infected. 

 14. 7. 13. The aphids are heavily infesting the Broad Beans, and appear to have all 

 left the Euonymus bushes. 



A few isolated, smaU colonies on the Rumex leaves. I found one winged 

 viviparous female on the Poppies, but no colonies forming yet on 

 these plants. 



Many winged viviparous females are produced, and a number are walking 

 on the roof of the tent as though wanting to escape. 



A few aphids present on the leaves of the Red Beet, but numbers very 

 few. 



Other plants not infected. 

 22. 7. 13. The Broad Beans are very heavilj' infested, although some of the plants 

 still have plenty of young growth to afford food for the aphids. 

 Many of the young pods are heavily infested with the aphids, and 

 the colonies have extended to about half-way down the stems in some 

 cases. Many colonies also beneath the leaves, and the winged 

 females present on these plants chiefly settle below the leaves, 

 although several are also on the stem. 



A few colonies are now forming on the Poppies being chiefly collected 

 along the flower- stalks, but some also on the stems and beneath the 

 leaves. 



There are a few colonies on the Red Beet and Sugar Beet, but very few in 

 number. Some of the Red Beet leaves are crinkled along the veins, 

 which seems to be due to the action of the aphids. 



Several of the Rumex plants have a few colonies, consisting of a small 

 number of individuals, present on the underside of the leaves. 



I found one or two small colonies of apterous forms present on the 

 Euonymus bush, but the aphids seem to have practically all left 

 these plants. 



There are no aphids on the Swedes, Nasturtiums and Onions. 

 10. 8. 13. The Broad Beans in many cases are ahnost smothered with aphids, the 

 underside of many of the leaves being almost covered with them. 

 They are also in great numbers on the young pods. The terminal 

 shoots of these plants are brownish in colour and dying off. 



The Shiiley Poppies are now fau'ly heavily infested, and there are many 

 winged viviparous females and nymphs on them. The aphids are 

 to a great extent collected along the flower-stalks, towards the flower- 

 heads, but also some along the stems and beneath the leaves. 

 There are several colonies also present on the Papaver rhoea 

 plants. 



There are a few isolated colonies, small in number, present on the Red 

 Beet and Sugar Beet ; and a very few aphids on the Mangolds, but 

 in this latter case only a small isolated colony on a very few 

 leaves.
