“…In the grasshopper species Melanoplus bivittatus (Orthoptera, Acrididae) a strong relationship between diet selection and grass quality was shown (Jonas and Joern 2008), indicating that plant defenses are not necessarily more important in food selection than nutrient composition. Furthermore, protein and amino acid content in food plants can affect different behavioral and physical characteristics of phytophagous insects (Behmer and Joern 1994, Scheirs et al 2004, Zavala et al 2004a, 2004b. Many studies have examined responses of insect herbivores to drought-stressed food plants (Mattson and Haack 1987, English-Loeb et al 1997, Schowalter et al 1999, Huberty and Denno 2004.…”

Extreme weather events like drought and heavy rain are likely to increase with climate change in Central Europe and may affect nutrient content in plants. They may therefore influence the performance (growth rate, developmental time, mortality, body size/mass, fecundity) and population dynamics of herbivorous insects. We conducted a common-garden experiment on food plants to investigate effects of severe drought and moisture events on reproduction and fitness components in the insect herbivore Chorthippus biguttulus (Orthoptera, Acrididae). Periodic irrigations of food plants were used to simulate a 60% decrease in average summer precipitation (drought treatment), a 40% increase in average summer precipitation (moisture treatment) and a normal summer precipitation (control treatment). Individuals of C. biguttulus that fed on drought-stressed plants showed beneficial effects on life-history traits including an increased reproductive success than grasshoppers that fed on control plants. The opposite was true for individuals feeding on plants grown under severe moisture conditions. We propose that herbivore performance is influenced by increased concentrations of soluble proteins and amino acids in plants under drought stress conditions. Our results suggest that drought events may increase population performance and consequently population density in the grasshopper species C. biguttulus, while extreme moisture events may cause negative population trends.

“…However, many examples can also be found in the literature where females did not seem to prefer oviposition sites that would be best for the performance of their offspring (Rausher, 1979;Courtney & Kibota, 1990;Valladares & Lawton, 1991;Underwood, 1994;Berdegué et al, 1998;Fritz et al, 2000;Scheirs et al, 2000Scheirs et al, , 2004Faria & Fernandes, 2001;Harris et al, 2001;Shiojiri & Takabayashi, 2003;van Nouhuys et al, 2003). Thus, suggested integrating the two concepts of optimal foraging and optimal oviposition in plantinsect research.…”

Abstract. Oviposition site selection is crucial for the reproductive success of herbivorous insects. According to the preference-performance hypothesis, females should oviposit on host plants that enhance the performance of their offspring. More specifically, the plant vigor hypothesis predicts that females should prefer large and vigorously growing host plants for oviposition and that larvae should perform best on these plants.The present study examined whether females of the monophagous leaf beetle Cassida canaliculata Laich. (Coleoptera: Chrysomelidae) prefer to oviposit on large host plant individuals of the meadow clary and whether large host plants are of higher nutritional quality than small host plants. Subsequently, it was tested whether the female preference correlates with offspring performance and survival.In the field, females preferred large host plant individuals for oviposition and host plant quality, i.e. leaf nitrogen content, was significantly higher in leaves of large than of small host plants. In the laboratory, larval development time was shorter on leaves of large host plant individuals than on small host plant individuals, but this could not be shown in the field. However, a predator-exclusion experiment in the field resulted in a higher survival of larvae on large host plants than on small host plants when all predators had free access to the plants. On caged host plants there was no difference in survival of larvae between plant size categories.It is concluded that females of C. canaliculata select oviposition sites that enhance both performance and survival of their offspring, which meets the predictions of the plant vigor hypothesis.

“…Female cicadas prefer to oviposit on young branches of trees in sunny areas (Marlatt 1907;Lloyd & White 1976;Yang 2006). Alternatively, cicadas may choose trees for reasons unrelated to offspring success, such as a preference for their natal tree species (Barron 2001) or to maximize their egg-laying success rather than offspring fitness (Scheirs et al 2004). There are some tree species that cicadas avoid to oviposit.…”

Advertisement calls of some cicadas are so loud that they are a nuisance to city-dwellers in Korea. We hypothesized that the densities of cicada species were directly correlated with the availability of host plant species. We conducted complete enumeration surveys of exuviae in Hyalessa fuscata, Cryptotympana atrata, Meimuna spp., and Graptopsaltria nigrofuscata in three representative habitats in Republic of Korea: metropolitan, suburban, and country. We measured resource-weighted density of each species based on the area and the number of trees, and used those values to calculate organism-weighted density, which measures the intensity of competition that an individual experiences sharing its host with others of its own species. H. fuscata was the dominant species in all three habitats. H. fuscata and C. atrata comprised a minimum of 75.2% of all cicadas across all habitats and sampling periods. Resource-weighted densities of H. fuscata and C. atrata were much higher in the metropolitan habitat than in the country habitat. Habitat was a significant factor for variations in organism-weighted densities in C. atrata and G. nigrofuscata, but it was not in Meimuna spp. and H. fuscata. Some of the results concerning the percentages of trees without exuviae and preferred plants seemed to support the host availability hypothesis in C. atrata, Meimuna spp. and G. nigrofuscata, but they may not in H. fuscata. The similarity between resource-weighted and organism-weighted densities suggests that factors other than host availability, speculatively abiotic factors and predators, may also account for the patterns of population densities in C. atrata and G. nigrofuscata.
