 The resistance of 'TKM 6' to Chilo suppressalis was not lowered when 

 hairs on the leaf blades of Oryza saliva L. were rubbed off with a wet cloth. 

 This suggested that for 'TKM 6', the pubescent lamina was not a major in- 

 fluence on ovipositional preference.

Because of the lack of toxicity of seedling and young plants, older Xicotiana 



plants should be used in screening tests for this type of resistance to the 



green peach aphid. Myzus persicae (Sulzer). Toxic exudates from certain tri- 



chomes of these plants increased in amount as the plants matured.

 There was direct acaricidal action attributable to leaf hair exudate of Ly- 

 copersicon. This was verified by topical application of the exudate to mites.

 Solarium pennellii Correll and segregates of five accessions of Lycopersicon 

 peruvianum (L.) Mill, were resistant to Macrosiphum euphorbiae (Thomas) 

 in the greenhouse. The entanglement of the aphids in the glandular hairs pre- 

 vented colonization on S. pennellii. but physiological incompatibility appeared 

 to be the reason that aphids failed to colonize the segregates of L. peruvian- 

 um, which have a sparse vesture of glandular hairs.

 Young leaves of Lycopersicon spp. were divested of exudate from glandular 

 hairs by washing with 75 percent ethanol. These leaves and unwashed senes- 

 cent leaves on older plants did not repel the tobacco flea beetle. Epitrix hir- 

 tipennis (Melsheimer).

 Tetranychus cinnabannus (Boisduval) and Tetranychus urticae became en- 

 tangled in the sticky exudate of the glandular hairs of S. pennellii and L. 

 hirsutum Humb. & Bonpl. and L. hirsutum f. glabratum C. H. Mull. 

 (69) 1968. resistance in "lycopersicon" and "solamm" to green-

 The sticky exudate from glandular hairs of 5. pennellii and L. hirsutum 

 trapped adults of Trialeurodes vaporanorum (Westwood).
