“…A similar conclusion was drawn by Cronin et al (1999) based on a study with North American populations of G. nymphaeae. In their study, field-collected (i.e., experienced) larvae and adults preferred the host from which they originated in pairwise choice experiments.…”

“…and Polygonum. Notwithstanding this, Cronin et al (1999) concluded, based on the variation in preference and performance, that at least two different ecotypes of G. nymphaeae occur in North America. Nokkala and Nokkala (1998) suggested that habitat races rather than host races are formed in Finnish G. nymphaeae living on N. lutea, Rubus chamaemorus, and Potentilla palustris (syn: Comarum palustre).…”

Host preference and larval performance suggest host race formation in Galerucella nymphaeae

In this study we investigated the possibilities for host race formation in Galerucella nymphaeae. This is a chrysomelid beetle feeding on four different hosts, belonging to two different plant families, the Nymphaeaceae and Polygonaceae. Previous results showed that beetles living on the two different host families differ in morphology, i.e., body length, mandibular width, and color of the elytra. In the current study, the preference of G. nymphaeae for four hosts was investigated, together with larval performance on these hosts. In a multichoice experiment, both parents and offspring showed a strong feeding preference for their natal host plant family: between 88-98% of the total consumption consisted of the natal host plant family. Females preferred to lay eggs on their natal host family: 81-100% of the egg clutches were laid on the natal host family. Host preference was accompanied by differences in offspring performance. Offspring survival was 1.2-25 times as high on the host family from which their parents originated than on the hosts of the other plant family. Furthermore, larval development tended to progress faster on the natal than on the other host family. Since the beetles use their host plant as a mating place, positive assortative mating is a likely consequence of the beetles' host preference. Together, these results suggest that there are two host races of G. nymphaeae: one living on Nymphaeaceae and the other on Polygonaceae.

“…al (1998), seem to suggest an element of host 414 dynamism (Fox and Morrow 1981;Bernays and Graham 1988), such that an herbivorous insect species may be a localized specialist while remaining a generalist over its geographic range (Cronin et al 1999). Monroe (1972) notes that M. gyralis was raised on Nuphar advena in Manitoba (Canada), and in South Carolina (USA), Stoops et al (1998) observed M. gyralis feeding on several species outside of the family Nymphaeaceae.…”

Although host preferences in phytophagous insects may be generated by several factors, few studies have simultaneously examined several potential host choice determinants. In this study we tested the impact of the following potential host choice determinants on host preference of the semi-aquatic lepidopteran Munroessa gyralis (Pyralidae): growth on different host plants; protein content, polyphenolic content, toughness, and chemical extracts of different host plants; prior feeding experience; and predation pressure on the caterpillar by fishes. Two water lilies, Brasenia schreberi and Nymphaea odorata, were preferred in cafeteria-style feeding experiments over 14 other species of vascular plants. The most preferred water lily (Brasenia) also afforded the fastest growth relative to three other species on which growth was measured. Feeding preferences across species were unrelated to protein content, polyphenolic content, or toughness. Domiciles constructed by caterpillars from leaf fragments were protective from field assemblages of fishes, but domiciles made from preferred or unpreferred host species conferred no significant protection from fish in the laboratory. Caterpillars responded positively to chemical cues of water lilies, and prior feeding experience increased preference for an otherwise unpreferred water lily (Nuphar advena) within the life-span of individual caterpillars. M. gyralis is a generalist herbivore exhibiting modest preference induction and preferences for and among members of the family Nymphaeaceae. Our results suggest that relative growth rates, chemical cues, and previous feeding experience are important factors determining feeding preference. Protein content, polyphenolic content, and toughness appear less important, and the importance of fish predators remains in question. As pupation seems to occur exclusively on Nymphaea, we suggest that host use may be restricted due to life-stage-specific developmental constraints that are not apparent from the results of growth or preference assays. It is currently unknown how often specific life-stages may restrict host use, but our work suggests this as a potentially important area of inquiry.

“…Organisms that consume living plant tissue are responsible for major herbivory losses by aquatic vascular plants. Chrysomelid beetles are known to specialize on vascular plants and some are used as biocontrols of floating vascular plants (Cronin, Schlacher, Lodge & Siska, 1999). Shredders that consume detritus have received a great deal of attention by stream ecologists.…”

Aquatic macroinvertebrates are involved in numerous processes within aquatic ecosystems. They often have important effects on ecosystem processes such as primary production (via grazing), detritus breakdown, and nutrient mineralization and downstream spiraling. The functional feeding groups (FFG) classification was developed as a tool to facilitate the incorporation of macroinvertebrates in studies of aquatic ecosystems. This classification has the advantage of combining morphological characteristics (e.g., mouth part specialization) and behavioral mechanisms (e.g., way of feeding) used by macroinvertebrates when consuming resources. Although recent efforts have greatly advanced our ability to identify aquatic macroinvertebrates, there is limited information on FFG assignment. Furthermore, there has been some variation in the use of the FFG classification, in part due to an emphasis on using gut content analysis to assign FFG, which is more appropriate for assigning trophic guilds. Thus, the main goals of this study are to (1) provide an overview of the value of using the FFG classification, (2) make an initial attempt to summarize available information on FFG for aquatic insects in Latin America, and (3) provide general guidelines on how to assign organisms to their FFGs. FFGs are intended to reflect the potential effects of organisms in their ecosystems and the way they consume resources. Groups include scrapers that consume resources that grow attached to the substrate by removing them with their mouth parts; shredders that cut or chew pieces of living or dead plant material, including all plant parts like leaves and wood; collectors-gatherers that use modified mouth parts to sieve or collect small particles (<1mm) accumulated on the stream bottom; filterers that have special adaptations to remove particles directly from the water column; and predators that consume other organisms using different strategies to capture them. In addition, we provide details on piercers that feed on vascular plants by cutting or piercing the tissue using sharp or chewing mouth parts and consume plant liquids. We also provide a list of families of aquatic insects in Latin America, with an initial assignment to FFGs. We recommended caution when assigning FFGs based on gut contents, as it can provide misleading information. Overall, FFG is a very useful tool to understand the role of aquatic macroinvertebrates in stream ecosystems and comparisons among studies will benefit from consistency in their use. Rev. Biol.
