Appeal No. 1997-2338
Application No. 08/173,376
ants and said selected species of ants are killed by exposure to said toxicant substance,
said method comprising the step of:
providing to said selected species of foraging ants a bait consisting essentially of:
(1) a toxic amount of a substance which is toxic to said selected species of ants
which is transportable by said selected species of foraging ants from a location external to
said ant’s nest back to said population of said selected species of ants, said substance
having delayed action sufficient to permit said selected species of foraging ants to
transport said substance back to their nest before said selected species of foraging ants
are killed by said substance;
(2) an effective amount of a behavior-modifying substance selected from the group
consisting of 3-octanol, 3-octanone, nonanol, decanal, dodecanal, 2- phenylethanol, citral,
farnesol, 6-methyl-5-hepten-2-one, 4-methyl-3-heptanone, decanoic acid, geraniol,
tetradecanal, $-pinene and mixtures thereof, said behavior modifying substance and said
toxic substance being in association with each other; and
whereby exposure of said selected species of ants to said behavior-modifying
substance induces said selected species of ants to transport a greater amount of said
toxic substance back to their nest, to admit said toxic substance to the nest and to
distribute said toxic substance to other members of said population of said selected
species of ants and said selected species of ants are killed by exposure to said toxic
substance.
61. A method of improving the amount of toxic substance retrieved by a selected
species of ants comprising the steps of:
providing to foraging members of said selected species of ants a toxic
substance in association with an effective amount of behavior modifying substance, said
behavior modifying substance comprising the structural equivalent of at least one
component of the alarm pheromone of said selected species of ants, whereby a greater
amount of said toxic substance is retrieved by said selected species of ants.
