| differential field responses of the little fire ant, wasmannia auropunctata (roger), to alarm pheromone enantiomers. | the little fire ant, wasmannia auropunctata (roger) (hymenoptera: formicidae), is an invasive ant with negative impacts on both biodiversity and agriculture throughout the tropics and subtropics. field experiments were conducted in order to elucidate the relative attractiveness of the enantiomers of the alarm pheromones, 2,5-dimethyl-3-(2-methylbutyl)pyrazine and 3-methyl-2-(2-methylbutyl)pyrazine. the enantiomers tested were synthesized from commercially available (s)-2-methylbutan-1-ol or kine ... | 2014 | 25370918 |
