“…This species is closely related to N. viridula, but it has a more northerly distribution in Japan (Kiritani et al, 1963). Nezara antennata produces two generations per year in the southern part of Wakayama Prefecture (Kiri tani et al, 1963), and our field observations in Kyoto City were consistent with this.…”

“…Nezara viridula has a worldwide distribution throughout tropical and subtropical regions (Todd, 1989;Panizzi et al, 2000b). It occurs only in the southern part of Japan, and the northern limit of its distribution in 1961-1962 was reported to be about 70 km south from Osaka City (Kiritani et al, 1963). However, this species is now common in Osaka City.…”

“…Thus, this species shows a long-dayshort-day photoperiodic response (Numata, unpublished). Because overwintering adults lay eggs in May and June (Kiritani et al, 1963), nymphs of the first generation develop under long-day conditions, enter summer dia pause as adults, and begin to lay eggs only after a decrease in daylength. Then, nymphs of the second gen eration develop under short-day conditions, and enter winter diapause as adults.…”

Abstract. Photoperiodic responses and their adaptive significance were examined in Riptortus clavatus (Heteroptera: Alydidae), Plautia crossota stali, Dolycoris baccarum, Aelia fieberi, Nezara viridula, Nezara antennata, Graphosoma rubrolineatum, Dybowskyia reticulata, and Eurydema rugosum (Heteroptera: Pentatomidae) in the Kyoto-Osaka area, central Japan. All of these spe cies overwinter as adults in diapause. Although they have similar feeding habits, their photoperiodic responses were quite different. Riptortus clavatus, P. c. stali, D. baccarum and N. viridula showed long-day photoperiodic responses with critical daylengths between 13 and 14 h, and were assumed to have three generations per year. The photoperiodic responses of the other five species were different both from those of the above species and from each other. These results suggested that A. fieberi and N. antennata pro duce two generations per year, and G. rubrolineatum, D. reticulata and E. rugosum have one or two generations per year. Nezara antennata showed a long-day-short-day photoperiodic response with summer adult diapause, which may avoid production of heatsusceptible nymphs in the hottest season. With the exception of N. antennata, the photoperiodic responses resulting in fewer genera tions were shown to be adaptations to dietary conditions in the field.

“…The temporal parameters of female calling song vary significantly among individuals and it has been suggested that variability might play a role in mate choice (Miklas et al, 2003b). Nezara viridula is often found syntopically with other stink bug species emitting vibrational signals with similar spectral and temporal characteristics (Cokl et al, 1978;Kon et al, 1988;Cokl et al, 2001;Blassioli Moraes et al, 2005) and interspecific copulations between N. viridula and N. antennata were observed in the field (Kiritani et al, 1963;Kon et al, 1993). Taking into account the potential predation risks associated with mate searching (e.g.…”

SUMMARYAnimals often communicate in environments with high levels of biotic noise that arises from the signals of other individuals. Although effects of background biotic noise on mate recognition and discrimination have been widely studied in air-born sound communication, little is known about incidental interference between signallers that use substrate-borne vibrational signals. In this study we investigated the ability of males of the southern green stink bug Nezara viridula (L.) (Heteroptera: Pentatomidae) to recognize conspecific female song in the presence of biotic noise originating from conspecific and heterospecific vibrational signals. We tested male responsiveness on a bean plant in playback experiments. One leaf was vibrated with conspecific female song, while to the other one we simultaneously applied either heterospecific female signal or various altered conspecific signals with different temporal parameters. We tested males in three levels of biotic noise, ranging from +6dB to -6dB and we compared male responsiveness in each treatment with response obtained in unilateral treatment with unaltered conspecific female calling song. Male responsiveness was reduced in the presence of heterospecific signals or when background noise from conspecific signals obscured the species-specific temporal pattern of conspecific female song. By contrast, the presence of two sources of conspecific female songs had a positive effect on male responsiveness, for as long as the signal repetition rate of perceived song did not differ from the species-specific value. In the presence of interfering background signals, searching activity was less affected than male signalling. Increased signal-to-noise ratio restored male responsiveness to the level expressed in unilateral stimulation with conspecific female song. The results are discussed with regard to male behavioural strategies for vibrational communication in a noisy environment. Supplementary material available online at

“…The African lineage of N. viridula is represented by only a single individual from Botswana (Kavar et al 2006) and this individual is the most genetically distant of all the COI haplotypes available from the genus Nezara ( antennata and N. viridula, but these pairings do not produce offspring (Kiritani et al 1963;Kon et al 1988). The specimen from Botswana may represent a misidentified individual of another Nezara species rather than a new species within what is currently described as N. viridula, but N. viridula is widely reported from Africa (Afreh-Nuamah 1983; Ivbijaro & Bolaji 1990;Khaemba & Mutinga 1982;Poutouli 1995;Sithole et al 1986).…”

The interaction between diet breadth, geography and gene flow in herbivorous insects

The geographical distribution and life history of insects and their host plants determines when, and if, they will interact. The vast majority of herbivorous insects are host-plant specialists and their narrow host range limits their distribution and may also restrict gene flow between their populations. Generalist insect herbivores, by contrast, might be expected to have much higher gene flow across populations because the distribution of multiple host plant species is likely to be much more contiguous. Species distributions shift continually, so with enough time the populations of a specialist insect species should experience more events that fracture their distribution because of the changing distribution of their relatively fewer hosts. The changing distribution of insects and their host plants is thus important for mediating host-plant interactions and will also influence how and when adaptation to a host plant, or subset of host plants, occurs.To investigate the influence of geography and host breadth on gene flow, and thus speciation, I explore the evolutionary history and population genetic structure of two herbivorous insects with different host plant relationships, the generalist bug Nezara viridula (Pentatomidae, Hemiptera), a global pest species, and the specialist thrips Cycadothrips chadwicki (Aeolothripidae, Thysanoptera), the pollinator in a brood-site mutualism with Macrozamia cycads. The results from these systems were then integrated with other similar data sets from phytophagous insects to understand better how gene flow and host specificity relate to one another, and to examine the role each has played (and may still play) in the evolution of insect-plant interactions more generally.The pest bug N. viridula has two globally distributed mitochondrial lineages, the Asian (mtDNA lineage A) and the European (mtDNA lineage E), and the species status of these lineages has not been resolved. In Australia, I found that both of these N. viridula mitochondrial lineages were present.Microsatellite data show two genetically and geographically distinct populations, but these did not correspond directly to the two mitochondrial lineages. Together, mtDNA and microsatellite data shown that secondary contact has occurred in eastern Australia between the two lineages and has resulted in introgression of mtDNA lineage A into predominantly mtDNA lineage E populations in a narrow area, but without widespread introgression across the nuclear genome. Past research on this insect suggested that these lineages represented a single species because these mtDNA haplotypes were found together in single populations. The evidence presented here indicates that mating between lineages can occur, but that an analysis of mtDNA alone is not enough to understand the evolutionary history of these Conference abstracts for both of the above references can be found in Appendix 2.
