34 p, 168.9 KB Geographical variation in alkaloid production in Conium maculatum populations experiencing differential herbivory by Agonopterix alstroemeriana / Castells, Eva (Universitat Autònoma de Barcelona. Departament de Farmacologia, de Terapèutica i de Toxicologia) ; Berhow, M.A. ; Vaughn, S.F. ; Berenbaum, M.R.
Conium maculatum, a Eurasian weed naturalized in North America, contains high concentrations of piperidine alkaloids, which act as chemical defenses against herbivores. In the United States, C. maculatum was largely free from herbivory until approximately 30 years ago, when it was re-associated via accidental introduction with a monophagous European herbivore, the oecophorid caterpillar Agonopterix alstroemeriana.

9 p, 285.6 KB Laboratory rearing of Agonopterix alstroemeriana, the defoliating poison hemlock (Conium maculatum L.) moth, and effects of piperidine alkaloids on preference and performance. / Castells, Eva (Universitat Autònoma de Barcelona. Departament de Farmacologia, de Terapèutica i de Toxicologia) ; Berenbaum, May R.
Conium maculatum L. (Apiaceae), or poison hemlock, is an invasive plant native to Europe that has become extensively naturalized throughout North America. This species contains piperidine alkaloids, including coniine and -coniceine, that are highly toxic to vertebrates. [...]

32 p, 155.9 KB Host plant selection by a monophagous herbivore is not mediated by quantitative changes in unique plant chemistry : Agonopterix alstroemeriana and Conium maculatum / Castells, Eva (Universitat Autònoma de Barcelona. Departament de Farmacologia, de Terapèutica i de Toxicologia) ; Berenbaum, M.R.
Host plant selection by ovipositing females is a key process determining the success of phytophagous insects. In oligophagous lepidopterans, host-specific plant secondary chemicals are expected to be dominant factors governing oviposition behavior; distinctive compounds can serve as high-contrast signals that clearly differentiate confamilial hosts from non-hosts increasing the accuracy of host quality evaluation. [...]

1 p, 308.8 KB Z-ocimene, but not alkaloids, deters oviposition of the specialist moth Agonopterix alstroemeriana on Conium maculatum (Apiaceae) / Castells, Eva (Universitat Autònoma de Barcelona. Departament de Farmacologia, de Terapèutica i de Toxicologia) ; Berenbaum, May
Conium maculatum (Apiaceae), a Eurasian weed naturalized in North America, contains high concentrations of piperidine alkaloids, such as γ-coniceine, coniine and conhydrinone, that are toxic for livestock and humans and might also confer resistance against phytophagous insects. [...]

1 p, 109.6 KB Genetic variation of alkaloid production in Conium maculatum after reassociation with the specialist moth Agonopterix alstroemeriana / Castells, Eva (Universitat Autònoma de Barcelona. Departament de Farmacologia, de Terapèutica i de Toxicologia) ; Berenbaum, May R.
Studies in biological control and invasion biology rarely determine whether introduced plants may rapidly evolve in the area of introduction. Examining the evolution of plant chemical defenses after reassociation with a coevolved enemy is important not only to understand the dynamics of plant-herbivore interactions but also in predicting potential ultimate outcomes of classical weed control programs. [...]
Total alkaloid production in C. maculatum was positively correlated with reassociation time between C. maculatum and A. alstroemeriana, with the longest historical association with A. alstroemeriana (NY) had highest alkaloid content; WA plants were intermediate, with the highest amount of variability among sites, and IL plants had lowest alkaloid concentrations. [...]
