ANNOTATED BIBLIOGRAPHY — PLANT HAIRS AND INSEC1 RESISTANCE ' 



CHESTNUTS

 lenhal).] [In Bulgarian/ Rastit. Zasht. 8: 69-71 . (R.A.E. 50:60 



The infestation of this weevil was in inverse ratio to the density of the 

 spines on the pericarp of Castanea spp.

Kuhma eupatorwides L.. a very hairy plant, was avoided by the grass- 

 hopper. Melanoplus femurrubrum (De Geer). in feeding preference tests. 



CORN

 differences in surface texture. J. Kans. Ent. Soc. 30: 59-63. 

 Experiments with an apparatus designed to test the ability of a moth to 

 cling to a surface showed that villous surfaces are best suited to moths of 

 Helwthis zea (Boddie) for maintaining a foothold.

 pubescence in corn as factors influencing leaf injury by the adult 

 western corn rootworm. J. Econ. Ent. 60: 1071-1073. 

 Zinc-deficient Z ea ma ) s L. had the least number of hairs per leaf and the 

 greatest amount of leaf injury. The close correlation between the amount of 

 leaf pubescence and amount of leaf injury indicated that pubescence may act 

 as a barrier to the feeding of the adults of Diabrotica virgifera LeConte. 



COTTON

ton plants to infestation with insect and mite pests. Bui. Soc. Ent.

 Two pubescent varieties of Gossypium were more susceptible to the cotton 

 aphid, Aphis gossypn Glover, than standard cultivars. A pubescent line was 

 more resistant to attack by a Lepidopteran, Spodoptera littoral is Boisduval 

 (=Prodenia litura (F.) ). and the Tetranychus complex. There were no sig- 

 nificant differences in resistance to a Lepidopteran. Earias insulana (Boisdu- 

 val), the pink bollworm. Pectinophora gossypiella (Saunders), or the onion 

 thrips. Thnps tabaci.

 Hair length on the lamina and thickness of palisade cells were the most 

 important characters in resistance of Gossypium sp. to Amrasca devastans 

 (Distant).
