 Hairiness of wheat {Triticum sp.) leaves favored the attack of the spring 

 fly, Hylemya ( = Phorbia) genitalis Schnabl.

1163-1166. 

 All highly resistant accessions of Triticum dicoccum Schrank were pubes- 

 cent, but this pubescence varied in density and size of hairs. Pubescent leaf 

 surface, per se, was not the sole factor in resistance to Oulema melanopus; 

 very susceptible pubescent accessions of Triticum dicoccum also were found.

FOR RESISTANCE TO THE CEREAL LEAF BEETLE. J. Econ. Ent. 62: 360-363. 



Larval survival of Oulema melanopus on resistant Triticum lines after 3 

 days was significantly reduced, and larval weights were significantly lower 

 on very resistant wheat. Seedlings of the pubescent wheat line, CI 8519, were 

 least preferred for oviposition.

61:900-903. 

 Densely pubescent wheat {Triticum sp.) was almost entirely avoided for 

 oviposition by Oulema melanopus. The number of eggs laid on plants was 

 significantly less for each increase in level of pubescence.

Triticum aestivum L. germinated and grown in closed petri dishes had 

 leaves with more pubescence than wheat grown under natural conditions. 

 Larval weight gain of Oulema melanopus was significantly lower on these 

 plants compared with the control plants.

 Hairy lines of Triticum were attacked less by Oulema melanopus than 

 smooth- leaved forms according to V. A. Megalov.

 Small grain seedlings were tested in the laboratory for resistance to Oulema 

 melanopus by exposing plants to prediapause adults. Wry pubescent wheat 

 lines had little seedling mortality; less pubescent Triticum lines and smooth- 

 leaved Avena and Hordeum lines were damaged extensively.
