GENETICALLY BASED POLYMORPHISMS IN MORPHOLOGY AND LIFE HISTORY ASSOCIATED WITH PUTATIVE HOST RACES OF THE WATER LILY LEAF BEETLE, GALERUCELLA NYMPHAEAE

Abstract L. lilii is a Eurasian chrysomelid beetle that was first found in Quebec, Canada, in 1943, from where it has spread to several Canadian Provinces, and Vermont and Maine in the USA. It was also reported in Boston, Massachusetts, in 1992, and it is now found in several New England States. It is also alien and invasive in the UK and, probably, in Northern Europe. The beetle most probably spreads with the sale and movement of potted lilies, flowering bulbs or cut flowers. In countries where it is invasive, it is a serious pest of cultivated lilies and fritillaries. Without control methods, leaves and flowers are totally defoliated by larvae. In North America, it also represents a threat to native lilies.

Conservation Concern

Invasive species are among the leading threats to global ecosystems due to impacts on native flora and fauna through competition and predation. The lily leaf beetle, Lilioceris lilii Scopoli (Coleoptera: Chrysomelidae), is an invasive pest of lilies (Lilium spp.) and other genera of Liliaceae (Liliales). A habitat suitability model was created using Maxent, to help predict if L. lilii will be able to establish in locations were native North American Liliaceae species grow. The model was created using georeferenced occurrence records from the beetle’s native, naturalized, and invasive range. Model results indicate that precipitation in the driest quarter and annual average temperatures are most strongly correlated with L. lilii distribution, and suggest that the species will perform poorly in very dry, hot, or cold environments. The model also indicates that the beetle should be able to establish throughout the range of most North American Liliaceae genera, including species of special conservation concern. This model can be used by natural area managers to identify areas of high habitat suitability that overlap with vulnerable North American Liliaceae species, and prioritize L. lilii monitoring and control activities as the beetle continues to expand its range.
