Eschscholtzia californica, California-poppy. (S) 



Bessey 1911 (16): Injury severe. 



Goff 1936 (96): Infestation to very heavy; majority of plants heavily

 tation on this plant.] Florida.

Watkins 1929 (248) : Eschscholtzia rated as "resistant." Florida. 



Euchlaena mexicana (E. luxurians), teosinte. (C) 



Bessey 1911 (16): No infestation found. 

 Euphorbia hirta. 



Linford 1939 (14®)' Appears highly resistant under Hawaiian field condi- 

 tions; roots highly attractive to larvae in vitro. 



Euphorbia hypericifolia (E. pilulifera). 



Bessey 1911 (16): Nematodes not abundant and no injury observed. 

 Euphorbia nutans (E. preslii), nodding spurge, upright spotted spurge.

Godfrey 1935: 49 Infestation commonly observed to be light. Hawaii. 



Euphorbia spp. (N) 



Grower: All euphorbias are seriously injured. California. 



A single host report, without estimate of severity, is known for each of 33 addi- 

 tional species including poinsettia, E. pulcherrima. The available data on infes- 

 tation are probably incomplete. 



Eustachys petraea. (C) 



Bessey 1911 (16): No infestation found. 

 Evening-primrose, see Oenothera. 

 Everlasting, see Helichrysum. 

 Fagopyrum vulgare (F. esculentum) , buckwheat. (C)

 specifically considered]. California. 



The California State Department of Agriculture has a record of infestation in

 house, District of Columbia]. 



Ficus carica, common fig. (N, S) 



Condit 1933 (45): Many infested trees can apparently produce fair crops in 



fertile soil; the replacing of killed rootlets is a drain on the vitality of 



the tree, the seriousness of which depends on the extent of infestation. 



California.
