 insect is also discussed.

 Biochemical Interaction Between Plants and Insects. Recent Adv. 

 Phytochem. 10: 271-350. 



The aspects of plant-insect interactions, discussed in previous sections of 

 this revie\f, have dealt primarily with laboratory or field experiments of 

 that aspect. The thrust of the boll weevil research program of the past 15 

 years was to develop a multidisciplinary technology to eliminate the insect. 

 From 1970 to 1974 a considerable number of field tests were done, including 

 the South Mississippi Pilot Bell Weevil Eradication Experiment (1971-1973). 

 Elements of plant-interaction have been included in most of the test regimens, 

 so it is on this basis that the results will be discussed.

 space volatiles of the cotton plant. Phytochemistry lA : 2088-2090. 



When the air space volatiles of cotton grown in the greenhouse were collected 

 and concentrated, they were found to possess a cotton plant odor. Upon analysis 

 54 compounds were identified: 4 aliphatic hydrocatbons, 17 aromatic hydrocarbons, 

 4 aliphatic and alicyclic carbonyl compounds, 4 aromatic carbonyl compounds, 

 9 aliphatic and alicyclic alcohols, 2 aromatic alcohols, 5 ethers and furans, 

 4 phthalates, and 4 miscellaneous compounds. Only 6 compounds, nonanal, 

 benzaldehyde, cumic aldehyde, 1-hexanol, isoborneol, and benzyl alcohol were 

 also found in cotton bud essential oil. In contrast, the cotton bud essential 

 oil has been found to contain at least 30 monoterpene and sesquiterpene hydro- 

 carbons and alcohols, 2 sesquiterpene oxides, 14 carbonyl compounds and 12 other
