“…With sufficient soil moisture, bittercress grows in the sun as well as in the shade of willows, Salix spp., or spruce, Picea engelmani Parry (Chew 1977;Louda & Rodman 1983a,b). This native herbaceous plant begins flowering in late June and typically sets seed in August or early September (Louda & Rodman 1983a).…”

“…3). It is likely that this within-plant distribution reflects differential attractiveness to the female (Chew 1977). Differences in secondary compound concentrations may be involved, at least in explaining the avoidance of very young, upper-position leaves, for these leaves have the highest concentrations of glucosinolates (Louda & Rodman 1983a).…”

“…Selective pressures should result in females ovipositing in leaves which promote increased larval development and survival (Mitchell 1975, Wiren & Larsson 1984, Larsson et al 1986; but see Chew 1977, Wolfson 1982. Therefore, larval occurrence and damage should reflect qualitative and quantitative differences in plant quality detectable by the ovipositing female (Chew 1977, Rausher 1979.…”

“…In these cases it would be an advantage if developing larvae could disperse and find new feeding sites. Whereas dispersal of insect larvae has been reported (Doak, 2000), little is known about their actual dispersal capacities and how they orient if they switch feeding sites (Chew, 1977;Bernays & Chapman, 1994;Berdegué et al, 1998;Soler et al, 2012). Whilst herbivorous larvae are often attracted by volatiles from their host plants (e.g.…”

Abstract. 1. Predatory larvae often have to face food shortages during their development, and thus the ability to disperse and find new feeding sites is crucial for survival. However, the dispersal capacity of predatory larvae, the host finding cues employed, and their use of alternative food sources are largely unknown. These aspects of the foraging behaviour of the aphidophagous hoverfly (Episyrphus balteatus De Geer) larvae were investigated in the present study.2. It was shown that these hoverfly larvae do not leave a plant as long as there are aphids available, but that dispersing larvae are able to find other aphid colonies in the field. Dispersing hoverfly larvae accumulated on large aphid colonies, but did not distinguish between different pea aphid race-plant species combinations. Large aphid colonies might be easier to detect because of intensified searching by hoverfly larvae following the encounter of aphid cues like honeydew that accumulate around large colonies.3. It was further shown that non-prey food, such as diluted honey or pollen, was insufficient for hoverfly larvae to gain weight, but prolonged the survival of the larvae compared with unfed individuals. As soon as larvae were switched back to an aphid diet, they rapidly gained weight and some pupated after a few days. Although pupation and adult hatching rates were strongly reduced compared with hoverflies continuously fed with aphids, the consumption of non-prey food most probably increases the probability that hoverfly larvae find an aphid colony and complete their development.

“…Observed relationships range from good correspondence between adult preference and some components of larval performance (e.g., Singer, 1972Singer, , 1983Rausher, 1982) to poor correspondence (e.g., Courtney, 1981Courtney, , 1982. In some cases poor correspondence between preference and performance may result from oviposition onto introduced host plants (e.g., Chew, 1977;Legg et al, 1986) or relative rarity of the preferred host (e.g., Williams, 1983).…”

The relationship between oviposition preference and growth, survival, and reproduction of offspring is the crux of the problem in the evolution of host associations between phytophagous insects and plants. Observed relationships between oviposition preference and performance of offspring range from good to poor. At least four hypotheses have been suggested to explain observed use of particular host plants that may not result in the fastest growth rates or greatest pupal masses: time, patch dynamics, parasite versus grazer lifestyles, and enemy-free space. Our current understanding of these relationships, however, is hampered by an almost complete lack of data on how preference and performance are related genetically. These data are needed to understand the origins of covariance between preference and performance and constraints on the evolution of host associations.
