TARCISSTJS 
HARCISSUS BULB ?LY ( L-'erodon egug str is Tab.) 
Washington C. D. Doucette (September IS): Infestations have been 
observed in practically every planting of narcissus in 
the State. Generally the infestation has been light, be- 
tween one-half of 1 and 2 per cent, with some exceptions. 
In one planting of 75,000 bulbs grown in Taeomr , the in- 
festation ranged from 40 to 65 per cert, defending on the 
seen. Elie large infestation was partly due to the fact 
that these bulbs had been in this field two successive 
years. 
Oregon C. ~. Doucette (September 16): Infestations have been 
observed in several sections producing nrrcissus bulbs. 
I have not had an opportunity to stud;' the conditions in 
Oregon as thoroughly as in Washington, hut consider that 
they are quite similar, as ell districts visited showed 
some infestation. Infestations of 3 per cent were ob- 
served in the Tillamook district, one-tenth of 1 per 
cent in the Columbia EiVer district, and 1 per cent in 
the Willamette Valley.
