giz. (From Chesnokov 1953, p. 13. Complete reference listed under 

 Wheat.) 

 The extent of downiness on leaves of Vitis spp. influenced the degree of in- 

 festation by the red spider {Epitetranychus sp.). 



LUPINS 



(57) Wogerek, W., and Dunajska, L. 1964. [the morphology and anatomy of 



LUPIN VARIETIES RESISTANT AND NONRESISTANT TO THE PEA APHID "MACRO- 



siphum PisuM."][In Polish.] Biul. Inst. Ochr. Rosl. 27: 1-15. (R.A.E. 54: 



511.) 

 Length and density of leaf hairs of Lupinus spp. were examined. There were 

 few hairs on the highly susceptible variety. The resistant lines had dense pu- 

 bescence, but it did not prevent access to the leaf surface by Acyrthosiphon 

 ( = Macrosiphum) pisum (Harris). 



OATS

cinella frit" (l.). Sver. Utsadesforen Tidskr. 66: 249-280. (From 

 Peregrine and Catling. 1967.) 

 Hirsute shoot bases in Avena were associated with the resistance of Oscinella 



frit (L.). 



(59) Peregrine, W. T. H., and Catling, W. S. 1967. studies on resistance in 



oats to the frit fly. Plant Pathol. 16: 170-175. 

 None of the forms of resistance to Oscinella frit (L.) in Avena found and 

 investigated in this study merited incorporation into a breeding program. 



PASSIFLORACEAE 



(60) Gilbert, L. E. 1971. butterfly- plant coevolution: has "passiflora aden- 



opoda" won the selectional race with heliconiine butterflies? Sci- 

 ence 172: 585-586. 



Hooklike trichomes of Passiflora adenopoda D.C. ( = acenfolia Cham, et 

 Schlecht.) provide a specific, absolute defense against butterfly larvae of 

 Heliconius erato (L.) and Heliconius melpomene (L.). See also Natl. Geog. 

 School Bui. No. 20., Feb. 14, 1972. 



RICE 



(61) Patanakamjorn, S., and Pathak, M. D. 1967. varietal resistance of rice 



TO THE ASIATIC RICE BORER, "CHILO SUPPRESSALIS" (LEPIDOPTERA: CRAMBI- 

 DAE), AND ITS ASSOCIATION WITH VARIOUS PLANT CHARACTERS. Ann. Ent. 



Soc Amer. 60: 287-292. 

 In general, varieties of Oryza sativa L. less susceptible to infestation by 

 Chilo suppressalis (Walker) were those with hairy upper lamina, tight leaf- 

 sheath wrapping, small stem with a ridged surface, and thicker hypodermal 

 layers.
