“…Ovipositing females should be favored by natural selection so as to lay eggs on plant species or parts on which offspring fitness is maximized (Thompson 1988). This advantage should be particularly true for insects immobile during the larval period, such as leaf miners, in which adult oviposition mainly determines larval feeding sites (Valladares and Lawton 1991;Auerbach and Alberts 1992;Stein and Price 1995). Therefore, we expect a positive correlation between preference and performance.…”

The relationship between oviposition preference and offspring performance of a leaf-mining moth (Paraleucoptera sinuella) on four Salicaceae species was investigated in 1997 and 1998. We observed the egg distribution pattern on different plant species in the field and carried out oviposition experiments in the laboratory to determine the preference of ovipositing females. We also examined larval survival, pupal mass, and developmental time to compare larval performance on each plant species. Egg density in the field differed significantly among plant species. However, egg density was not correlated exactly with demonstrated oviposition preference. No larvae could develop on two Salix species. This finding indicated that larval survival is the most critical index of larval performance. Larval performance on each plant species was correlated well with oviposition preference that was revealed by a no-choice experiment in the laboratory. However, this correlation was not found in the field. These results indicate that the preference-performance linkage that was observed under laboratory conditions, was not always maintained in the field.

“…The Plant Vigor Hypothesis (PVH; Price 1991) predicts that insect herbivores will choose preferentially large, more vigorously growing plants or plant modules and that offspring performance will be greater on these more vigorous plants or plant modules. Its predictions have been widely tested in diverse ecosystems around the world, being either fully supported (Price et al 1987a, b;Craig et al 1989;Kimberling et al 1990; Price and Ohgushi 1995;Stein and Price 1995;Woods et al 1996;Carr et al 1998;Inbar et al 2001;de Bruyn et al 2002), partially supported (Cornelissen et al 1997;Prado and Vieira 1999;Cornelissen and Fernandes 2001c;Fritz et al 2000;Ferrier andPrice 2004), or refuted (de Bruyn 1995;Faria and Fernandes 2001;Rehill and Schultz 2001). Faria and Fernandes (2001) argued that the amount of resources has been generally underestimated in large size class shoots.…”

Long term oviposition preference and larval performance of Schizomyia macrocapillata (Diptera: Cecidomyiidae) on larger shoots of its host plant Bauhinia brevipes (Fabaceae)

The Plant Vigor Hypothesis (PVH) proposes that natural selection on female oviposition choice results from higher fitness of larvae on more vigorous and larger plant modules. For six consecutive years we tested the PVH predictions by investigating the effect of shoot size of Bauhinia brevipes (Fabaceae) on the oviposition preference and offspring survival of the gall-midge Schizomyia macrocapillata (Diptera: Cecidomyiidae). Additionally, we analyzed the effects of bottom-up and top-down mortality forces on the system. The hypersensitive reaction (bottomup effect) accounted for more than 90% larval mortality of S. macrocapillata, making available few galls to be found and killed by natural enemies (top-down effect). Smaller shoots were always more abundant while longer shoots were rare. Nevertheless, the percent number of galls induced by S. macrocapillata was up to 10-fold greater on the largest shoots, corroborating the preference prediction of the PVH. Schizomyia macrocapillata should use over-exploit larger shoots to maximize the preference for, and consequently increase the performance on these shoots. Our results partially support the performance prediction of the PVH: (1) the observed survival was higher than expected on longer shoots, and (2) the ratio of survival per shoot was positively related with shoot length only in 2 years. Thus, we found a link between female preference and larval performance on large-sized shoots, at least in some years. The gall-midge attack pattern in this study might be an evolved response to maximize the female preference and increased larval performance on longer shoots of the host plant.

“…Researchers frequently measure the association (phenotypic or genetic) between the oviposition preference of females and the performance of their offspring. If there is a positive association between adult oviposition preference and the performance of offspring, compelling ecological and evolutionary stories can be told (Rausher, 1982;Via, 1986;Singer et al, 1988;Bossart & Scriber, 1995;Stein & Price, 1995;Gu et al, 2001), but the scenarios are more complicated when no concordance is found (Courtney, 1981;Thompson, 1988;Fox, 1993;Janz et al, 1994;BerdegueÂ et al, 1998;Gratton & Welter, 1998;Leyva et al, 2000). In these cases, finding an ecologically or evolutionarily plausible explanation for the observed patterns of adult preference and juvenile performance can be daunting, but potentially revealing of what ecological processes are involved and might drive evolution in natural populations.…”

Abstract. 1. The butterfly Melitaea cinxia uses two host plant species in the A Ê land Islands of south-west Finland. Survey data show that host plant use is spatially variable and that the two species are not used (fed on by M. cinxia larvae) in proportion to their abundances. The pattern of host plant use by M. cinxia has been attributed in part to plant distribution and spatial variation of butterfly oviposition preference.2. The additional roles that may be played by spatial variation in host plant quality and larval physiology (performance ability) were investigated. Seven years of field survey data and a series of laboratory experiments were used to demonstrate that neither of these variables contributed measurably to the observed pattern of host plant use.3. Specifically, while there was great variation among individuals in both the performance ability of caterpillars and host plant suitability, the two plant species appeared equally suitable, there was no within-species geographic variation in plant suitability, and there was no evidence for adaptation of caterpillars to the locally used host plants.
