In Papilio machaon host plant utilization is argued to be proximally guided by adult and larval preferences, both of which are genetically determined. To decide whether these preferences are controlled by one or two gene complexes, oviposition preferences and larval survival of a Scandinavian population were investigated with regard to all potential host plants in the region. The experiments revealed a substantial difference between the potential host plant ranges of the adults and the larvae, indicating that adult and larval host plant preferences are determined by separate gene complexes.

This study addressed the possible behavioraHnduction effects of previous exposure to several specific host plants on subsequent host "preference hierar chy" and "specificity" (i.e .. how far down the ranking order a female will go) in the most polyphagous swallowtail butterfly in the world, Papilio glaucus (Papilionidae). Multi-choice preference bioassays using individual females in revolving arenas were used to assess one of the potentially most significant non-genetic sources of variation: learned (or induced) oviposition preferences. Results of the 4-choice studies using tulip tree (Liriodendron tulipifera; Mag noliaceae), black cherry (Prunus serotina; Rosaceae), quaking aspen (Populus tremuloides; Salicaceae), and hoptree (Ptelea trifoliata; Rutaceae), fail to show any significant oviposition preference induction with two-day prior exposure to any of the host species tested. It appears that the eastern tiger swallowtail butterfly, while polyphagous as a sp...
Evolutionary Ecology of Oviposition Strategies
Chemoecology of Insect Eggs and Egg Deposition, 2003
Finding and choosing a good site for oviposition is a challenging task for females of herbivorous insects, and her decision has far-reaching and profound consequences for the life history of her offspring. One of the most prominent features of host plant preference is that the range of host plants accepted for oviposition is often very narrow. The reason for this widespread specialization is a question that has puzzled researchers for many years, and even though interesting progress has been made, it still waits for a completely satisfying answer. The oviposition strategy of an insect is a complex trade-off between many, sometimes contradictory, factors, including host plant range, clutch size, host quality, the difficulty of finding hosts of sufficient quality, the chances of finding even better hosts, predation risks on her and her offspring, larval mobility and host-finding capability, microclimate, etc. Thus, although the female's prime goal may be to choose an oviposition site that maximizes offspring survival and performance the outcome is not necessarily a perfect match between female host plant preference and larval performance.

1. A series of experiments was conducted to measure the impact of plant genotype, plant growth rate, and intraspeci®c competition on the oviposition preference and offspring performance of the host races of Eurosta solidaginis (Diptera: Tephritidae), a¯y that forms galls on Solidago altissima and Solidago gigantea (Asteraceae). Previous research has shown that both host races prefer to oviposit on their own host plant where survival is much higher than on the alternate host plant. In this study, neither host race showed any relationship between oviposition preference and offspring performance in choosing among plants of their natal host species.

Cera/ilis capi/ala, fruit tlies, oviposition behavior, insects Host pl ant selection is one ofthe central questions in the study ofinsect-plant relations. This factor is of criticaI impOltance in holometabolic insects because the larvae ofthese insects have relatively Iittle mobility and depend for survival on the nutritive resources determined by adult females through their ovi posi ting behavior (SINGER 1986; RENWICK 1989). A controversial point about host selection by females is ifthey would be ab le to select the host plant that would permit best immature performance. Knowledge ofthe relation between ovipositing preference and larval performance is crucial for the understanding of the changes in host (THOMPSON 1988; CRAIG et aI. 1989). Hierarchical preferences for plant resources have been reported for various phytophagous insects (COURTNEY 1986; THOMPSON 1988) and a sim pie evolutionary hypothesis for explaining this hierarchy of preference is that the latter may correspond to the quality of the resources for offspring performance (RAUSHER 1979). The existence of a positive correlati on between host se lecti on for ovipositing and offspring performance has been demonstrated in some spec ies (
Choice of oviposition sites by Manduca sexta and its consequences for egg and larval performance
Entomologia Experimentalis et Applicata, 2012
The preference-performance hypothesis predicts that female insects should prefer to lay eggs in locations that enhance offspring performance. This study examines the choices of females regarding where to oviposit within plants, focusing on the hawkmoth Manduca sexta L. (Lepidoptera: Sphingidae) and its host Datura wrightii Regel (Solanaceae) in the southwestern USA. Smaller Datura leaves provide cooler microclimates for eggs (which may lead to faster embryonic development, shortening their exposure to egg predators) and more nitrogen for larvae. In contrast, large leaves reach temperatures that are stressfully high (which slows embryonic development) and provide less nitrogen for larvae. Thus, we would expect females to oviposit on small leaves. To examine whether leaf size influences female preference and offspring performance, we used laboratory and field studies to address the following questions. On what size leaves do females typically oviposit? (2) Does the distribution of eggs in nature differ from that expected by chance? And (3) how does leaf size affect survival or growth of eggs and larvae? We find that oviposition choices of females do not lead to the highest probability of offspring survival. Females lay eggs on larger leaves, likely due to the greater accessibility of those leaves; however, eggs are more likely to hatch on small leaves. Larvae grow faster on large leaves, but larvae are also surprisingly mobile, suggesting that the consequences of oviposition site are minor once eggs have hatched. Larval mobility was seen only in the field, not in the laboratory, emphasizing the importance of field studies for predicting real-world performance. Although females' leaf choices are potentially risky for eggs, the threats of high temperature and predation may vary sufficiently in space and time that there is no consistent selection for strong preferences. Furthermore, the fitness consequences for eggs and larvae largely offset each other and offspring are sufficiently mobile to cope with the conditions where they are laid.
