“…The half-life of MP may reflect not just temporal changes in the relative payoffs for first and second clutches (Quiring & McNeil, 1984;Visser et al, 1992), but changes in who encounters the mark. Some MPs may be designed to last only as long as the marker herself is likely to revisit the marked host (Okuda & Yeargan, 1988;Nelson & Roitberg, 1993).…”

Oviposition behavior in phytophagous insects and entomophagous parasitoids is often modified by the presence of conspecific brood (eggs and larvae). Often, females avoid laying eggs on or in hosts bearing brood, a behavior that acts to reduce the level of competition suffered by their offspring. Avoidance of occupied hosts is typically mediated by cues and/or signals associated with brood. In this article, we review the role of Marking Pheromones (MPs) as signals of brood presence in both phytophagous and entomophagous insects. We place information about the function and evolution of MPs in the context of recent theory in the field of animal communication. We highlight the dynamics of host-marking systems and discuss how effects of MPs vary according to factors such as female experience and egg load. We also examine variation in the form and function of MP communication across a variety of insect taxa. While studies of MP communication in phytophagous insects have focused on the underlying behavioral mechanisms and chemistry of MP communication, studies in entomophagous insects have focused on the functional aspects of MPs and their role in 'decision-making' in insects. We argue that an approach that incorporates the important contributions of both of these somewhat independent, but complementary areas of research will lead to a more complete understanding of MPs in insects. Finally, we suggest that MP systems are model systems for the study of animal signaling and its evolution.

“…The cost of superparasitism in this system is rather lower than it is in other systems where host marking occurs. In many such systems, larvae are cannibalistic and crowding effects become manifest when even two larvae share the same host (Quiring and McNeil 1984;Bauer 1986;Averill and Prokopy 1987;Roitberg and Prokopy 1987). O. ruficauda larvae are not cannibalistic (Lalonde and Roitberg 1992) and we show here and elsewhere (Lalonde and Roitberg 1992) that clutches of up to 4 eggs show no strong detrimental effects of crowding.…”

Female Canada thistle seed flies (Orellia ruficauda) preferentially oviposit into seed heads which are a single day from opening. When flies are forced to oviposit into flower heads at other stages of development, offspring typically do slightly poorer: they attain a mature mass of about 15% less than do larvae derived from preferred hosts. Larval mass correlates strongly with reproductive success: heavy larvae develop into adults that produce eggs at a faster rate than do those developing from small larvae. After laying a clutch of eggs, flies circumscribe the rim of the flowerhead with their extended ovipositor and deposit a clear fluid. Flies reject previously-attacked hosts, bearing this apparent marking pheromone, significantly more often than they reject unattacked hosts. Costs of superparasitism in this system are relatively small, inasmuch as there is only a weak relationship between clutch size and larval success at the densities measured in this study. We speculate that flies are highly selective, when the apparent costs of making a mistake are rather low, because the information provided by phenological cues and by the putative marking pheromone is highly reliable, and low fecundity and time costs allow sufficient time to express a high level of discrimination.

“…They point out that the high mortality faced by larvae exhausting a resource prematurely generally outweighs the decrease in the total number of eggs laid when females lay clutches smaller than the capacity of the patch, especially when the risk of predation or the search time associated with finding a new patch is small. A reduced likelihood of oviposition on resource patches already bearing eggs has been reported for several insects (Prokopy 1972;Rausher 1979;Quiring & McNeil 1984;Messina & Renwick 1985;Ives 1989), while other studies have found no relationship between egg load and subsequent oviposition (Singer & Mandracchia 1982;Ives 1989). The large amount of scatter when Omphalocera clutch size is correlated with the number of leaves on a pawpaw indicates that, while females can adjust clutch size, their control over clutch size is limited.…”

SUMMARY(1) Insects that lay their eggs in groups can influence the success of their offspring not only by selectively laying eggs on hosts of high quality, but also by adjusting the number of eggs that they place on hosts.(2) The oviposition behaviour of females of the pyralid moth, Omphalocera munroei, leads them to vary the number of eggs placed on their food plants in the genus Asimina in such a way as to reduce the impact of within-species competition.(3) Plants with many leaves are more likely to have eggs laid on them, receive larger clutches, and receive more clutches than plants with few leaves.(4) The number of eggs placed on a plant more closely reflects the carrying capacity of the plant when natural mortality rates are taken into consideration than it does the carrying capacity in the absence of mortality.(5) The overall effect of the oviposition behaviour of 0. munroei is to reduce substantially the likelihood that the moth larvae will be forced to abandon the plant before they complete development, thus increasing their chances of survival to reproduction.
