“…This fact alone makes it unlikely that the morphological differentiation is due to phenotypic plasticity. We know from only one study which has found host plant‐induced shape variation in herbivorous insects, namely, Gillham & Claridge's (1994) study of Alnetoidia alneti leafhoppers. However, these leafhoppers are hemimetabolous.…”

“…Host plants differ, for example, in nutritional value (Häggström & Larsson, 1995) and amount of secondary metabolites (Roitberg & Isman, 1992). This can translate into host‐related body‐size differences (e.g., Leclaire & Brandl, 1994; Stoyenoff et al., 1994; Lill & Marquis, 2001; Blair et al., 2005), but also into host‐plant induced shape variation (Gillham & Claridge, 1994).…”

The present study investigates morphological differentiation among host races of the fruit fly Tephritis conura Loew (Diptera: Tephritidae) for two fitness‐related traits and whether these traits are host induced or genetically determined. Flies were analyzed from independent sympatric regions, and from one syntopic site where parental host plants [Cirsium heterophyllum (L.) Hill. and Cirsium oleraceum (L.) Scop. (Cardueae)] and hybrid plants (C. heterophyllum×C. oleraceum) co‐occur. As both host races may oviposit on hybrid plants and hybrid plants provide an identical environment for larvae of both host races, flies emerging from C. heterophyllum×C. oleraceum hybrids were used to assess whether host‐race morphological differences are genetically determined or due to phenotypic plasticity. No significant size (wing length) differences were found among host races, whereas flies emerging from C. heterophyllum had on average 8.4% longer ovipositors than flies emerging from C. oleraceum. The mean size‐corrected ovipositor length (i.e., the ratio ovipositor/wing length) was 10.3% longer. These proportions were repeated among host races emerging from hybrid plants. Although flies of the C. heterophyllum host race from hybrid plants were smaller than on parental host plants, the ratio ovipositor/wing length was constant. Hybrid flies (which emerged only on hybrid plants) were intermediate in relative and absolute ovipositor length. Thus, ovipositor‐length differences among T. conura host races most likely have a genetic basis. This suggests that host‐related differences in ovipositor length reflect adaptations to the respective host‐plant species, most likely to the host's flower‐head size, whereas both host races experience similar selection regimes on body size.

“…Loader & Damman (1991), Häggström & Larsson (1995), Björkman (1997) and others showed that herbivore populations living on different host species differed in average body size. Other morphological traits that may differ between diets include shape (Gillham & Claridge, 1994), larval appearance (Greene, 1989), wing form (Denno & Douglass, 1985) mandible size (Bernays, 1986;Greene, 1989) and colouration (Fescmeyer & Erlandson, 1993;Grayson & Edmunds, 1989). Life history traits influenced by the host species on which the herbivore feeds include survival rate (Goyer et al, 1995;Fox et al, 1994;Rank, 1994), development time (Guldemond et al, 1994;Stoyenoff et al, 1994), tendency to enter diapause (Hunter & McNeil, 1997;Wedell et al, 1997) and phenology (Feder et al, 1993).…”

The water lily beetle Galerucella nymphaeae L. (Coleoptera: Chrysomelidae) exploits different hosts, including Nuphar lutea Sm. and Nymphaea alba L. (both Nymphaeaceae), as well as Polygonum amphibium L. and Rumex hydrolapathum Hudson (both Polygonaceae). The present study investigates whether within‐species differences in morphological and reproductive traits are associated with differences in host species exploitation. A total of 1103 adult beetles were collected from 11 localities in The Netherlands, one of which contained all four hosts and three other localities contained hosts from both families (sympatric localities). Adults originating from Nuphar and Nymphaea were on average darker in colour and larger in size and had disproportionally bigger mandibles than beetles originating from Polygonum and Rumex across the 11 localities. Head capsules of first instar larvae from Nymphaeaceae hosts were between 17% and 28% larger than those of larvae from Polygonaceae hosts. Furthermore, beetles from Nuphar and Nymphaea laid larger sized eggs, but fewer eggs per clutch than beetles originating from Polygonum and Rumex. Although host related variation was less pronounced at the sympatric localities than in the allopatric localities, differences in larval and adult size were still highly significant at the sympatric localities. It is not clear whether the observed differences are genetically based, as opposed to host induced. However, leaf toughness varied among species in a way suggesting that leaf toughness may be partly responsible for host related differences in G. nymphaeae.

“…Ideally, differentiation is best achieved by experimental rearing and transfer between hosts (Claridge and Gillham 1992). For example Gillham and Claridge (1994) reported results of multivariate analyses of morphological characters of the common polyphagous, tree-feeding leafhopper, Alnetoidia alneti (Dahl. ), in Europe.…”
