e2“Its concentration in the wax varies considerably with cultivar and in some (e.g. 6SD and CSH 1) it is present at concentrations which are highly deterrent to Locusta”
e0“The deterrent effects of a lipid extract from seedling Sorghum bicolor on Locusta migratoria migratoroides (R. & F.) reside in several of the surface wax components of the extracts”

Other claims from this paper (5)
- Observation ρ‐Hydroxybenzaldehyde is present in the surface wax of all sorghum cultivars examined and acts as an antifeedant against Locusta.
- Association The concentration of ρ‐Hydroxybenzaldehyde in sorghum wax decreases with increasing plant age.
- Observation Sorghum seedlings contain deterrent amounts of the wax antifeedant only in the early stages of growth.
- Observation Sorghum seedlings appear to have thicker or more resistant cuticular waxes than other Gramineae.
- Observation The chemical composition of the surface waxes of the sorghum cultivars examined is qualitatively similar.
