The active ingredient has been profiled in comparison to analogous derivatives in a battery of assay systems inter alia, against Aphis craccivora, Myzus persicae, Nilaparvata lugens, Spodoptera littoralis and Diabrotica balteata), and proved to be superior (Fig. 8.52 and Fig. 8.53).

Dimethylnonyl propanoate 196 (Scheme 22), the female produced sex pheromone of several corn root worm species, Diabrotica spp. keeps ( -configuration at the methyl branching, whereas the stereochemistry at the oxygen function may vary with species (including the formation of mixtures) [359,360]. The structure of the pheromone of the southern corn root worm D. undecim-punctata, ( )-10-methyltridecan-2-one 197, is closely related to 196 [361,362]. Compared with 196 and 197, (6R, 122 )-6,10-dimethylpentadecan-2-one 198, the sex pheromone of D. balteata shows similar structural features [363,364].
