Abstract
Abstract A pheromonal compound produced by the southern corn rootworm has been identified as 10-methyl-2-tridecanone (10-M-2-T) having the structural formula: <IMAGE> The synthetic R-enantiomer of 10-M-2-T demonstrates activity toward the southern corn rootworm comparable to its natural counterpart, whereas the synthetic racemic mixture is characterized by approximately half the activity for a given amount. Related diabroticites such as the western spotted cucumber beetle also respond to the synthetic compounds. By attracting adult beetles to field traps, 10-M-2-T is a useful tool for the monitoring and control of these major agricultural pests.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
38 words
A method of attracting a male Diabrotica undecimpunctata adult to a locus for the monitoring or control of reproduction in adult populations, comprising applying to said locus an effective amount of 10-methyl-2-tridecanone in combination with a suitable carrier.
Claim 2
Independent Claim
38 words
A method of attracting a male Diabrotica undecimpunctata adult to a locus for the monitoring or control of reproduction in adult populations, comprising applying to said locus an effective amount of 10-methyl-2-tridecanone in combination with a suitable carrier.
Claim 3
Dependent Claim
30 words
A method as described in claim 1 wherein said Diabrotica undecimpunctata is a subspecies selected from the group consisting of D. u. howardi, D. u. undecimpunctata, and D. u. duodecimnotata.
Claim 4
Dependent Claim
19 words
A method as described in claim 1 wherein said 10-methyl-2-tridecanone is the racemic mixture of its R- and S-enantiomers.
Claim 5
Dependent Claim
18 words
A method as described in claim 1 wherein said 10-methyl-2-tridecanone is configurationally biased in favor of its R-enantiomer.
