“…Differential host plant use and differential effects of natural enemies have been suggested as contributing factors to displacement among Liriomyza species in the United States (Reitz and Trumble 2002a,b) and Japan (Abe and Tokumaru 2008). The results of the current study partially explain the roles that can be played by both host plants and parasitoids in the displacement of Liriomyza species.…”

Host plant species can affect the behavior and attributes of parasitoids, such as host searching, oviposition, and offspring fitness. In this study, parasitism, host feeding, and sex ratios of Diglyphus isaea (Walker) (Hymenoptera: Eulophidae) on Liriomyza huidobrensis (Blanchard), Liriomyza sativae Blanchard, and Liriomyza trifolii (Burgess) (Diptera: Agromyzidae) larvae reared on Phaseolus vulgaris L., Pisum sativum L., Solanum lycopersicum L., and Vicia faba L. were determined. In no-choice tests, L. huidobrensis had the highest rate of parasitism when reared on P. vulgaris (46%), L. sativae when reared on V. faba (59%) and P. vulgaris (59%), and L. trifolii when reared on S. lycopersicum (68%). Host feeding in no-choice tests ranged between 2% and 36% and was highest on L. trifolii reared on V. faba. Results of choice tests showed a significant interaction effect for host plant and Liriomyza species on parasitism and host feeding. Within plant mixtures, L. sativae reared on P. vulgaris had the highest rate of parasitism (31%), followed by L. trifolii on S. lycopersicum (29%) and L. huidobrensis on V. faba (28%). Host feeding was highest on L. trifolii reared on S. lycopersicum (14%) and lowest on L. huidobrensis reared on P. sativum and S. lycopersicum (1%). In some instances, plant mixtures resulted in a higher proportion of females of D. isaea than single plant species. The highest proportion of females was obtained in plant mixtures on L. huidobrensis and L. trifolii on V. faba (71 and 72%, respectively). This study suggests that planting crop mixtures can potentially lead to higher proportions of females, thus improving parasitism and host feeding, depending on Liriomyza and host plant species. Keywords: biological control, leafminer, ectoparasitoid, sex ratio, tritrophic interactionsThe leafmining flies Liriomyza huidobrensis (Blanchard), Liriomyza sativae Blanchard, and Liriomyza trifolii (Burgess) (Diptera: Agromyzidae) are economically important pests of a wide range of greenhouse and field-grown plants (Murphy and LaSalle 1999, Liu et al. 2009). These three pests are considered alien invasive species in the Afrotropical region, and L. trifolii was first reported in Kenya in 1976, where 10 yr after its accidental introduction the pest was found to be widespread from the coastal regions to the highlands (Spencer 1985). The three Liriomyza species are highly polyphagous, attacking plants in several families 1 (Murphy and LaSalle 1999). Globally, they are important pests of high value horticultural crops such as snow pea (Pisum sativum L.; Fabaceae), French bean (Phaseolus vulgaris L.; Fabaceae), runner bean (Phaseolus coccineus L.; Fabaceae), okra [Abelmoschus esculentus (L.) Moench; Malvaceae], aubergine (Solanum melongena L.; Solanaceae), tomato (Solanum lycopersicum L.; Solanaceae), and passion fruit (Passiflora edulis Sims; Passifloraceae), and they can cause yield losses of up to 100% (Spencer 1973(Spencer , 1990Kotze and Dennill 1996;Chabi-Olaye et al. 2008;Gitonga et al. 2010).Previous ...

“…The main reason for the displacement of L. sativae by L. trifolii in Hainan Island, China and California, USA, has been thought to be the lower susceptibility of L. trifolii populations to many commonly used insecticides [2], [3]. In contrast, Abe and Tokumaru [13] concluded that the reason for the displacement of L. trifolii by L. sativae in Kyoto Prefecture of Japan is the higher fecundity of L. sativae and differential effects of the local parasitoid complex on the two Liriomyza species. These mechanisms are likely to be mediated by other local environmental conditions, including temperature.…”

Does Temperature-Mediated Reproductive Success Drive the Direction of Species Displacement in Two Invasive Species of Leafminer Fly?

et al. 2014

Liriomyza sativae and L. trifolii (Diptera: Agromyzidae) are two highly invasive species of leafmining flies, which have become established as pests of horticultural crops throughout the world. In certain regions where both species have been introduced, L. sativae has displaced L. trifolii, whereas the opposite has occurred in other regions. These opposing outcomes suggest that neither species is an inherently superior competitor. The regions where these displacements have been observed (southern China, Japan and western USA) are climatically different. We determined whether temperature differentially affects the reproductive success of these species and therefore if climatic differences could affect the outcome of interspecific interactions where these species are sympatric. The results of life table parameters indicate that both species can develop successfully at all tested temperatures (20, 25, 31, 33°C). L. sativae had consistently higher fecundities at all temperatures, but L. trifolii developed to reproductive age faster. Age-stage specific survival rates were higher for L. sativae at low temperatures, but these were higher for L. trifolii at higher temperatures. We then compared the net reproductive rates (R 0) for both species in pure and mixed cultures maintained at the same four constant temperatures. Both species had significantly lower net reproductive rates in mixed species cultures compared with their respective pure species cultures, indicating that both species are subject to intense interspecific competition. Net reproductive rates were significantly greater for L. sativae than for L. trifolii in mixed species groups at the lower temperatures, whereas the opposite occurred at the higher temperature. Therefore, interactions between the species are temperature dependent and small differences could shift the competitive balance between the species. These temperature mediated effects may contribute to the current ongoing displacement of L. sativae by the more recent invader L. trifolii in warm climatic areas of China.

“…Outcomes of invasions could include: (1) the replacement of one (or more) species by the newest invader (e.g. Reitz & Trumble 2002, Abe & Tokumaru 2008; (2) resistance to or exclusion of the newest invader by the established community of species (e.g. Elton 1958, Moulton & Pimm 1983, Robinson & Dickerson 1984, 1987, Case 1990, Drake 1990, Case 1991, Stachowicz et al 1999; or (3) niche shift or compression, in which species coexist but use less of their fundamental niche than they did prior to the latest invasion (e.g.…”

Battle of the barnacle newcomers: niche compression in invading species in Kaneohe Bay, Oahu, Hawaii

Multiple invasions by ecologically similar species can be viewed as 'natural' addition experiments in which access to key resources might be reduced. Possible outcomes might include:(1) the extirpation of a species already present in the ecosystem, (2) the exclusion of a new invader, or (3) niche compression, with each species using less of the shared resource. Chthamalus proteus, a barnacle that arrived in the Hawaiian Islands ~30 yr ago, is now the most abundant and widespread non-native barnacle in the intertidal zone on the island of Oahu. In a series of field experiments, I demonstrate that the abundance of an earlier invader -the larger, faster growing barnacle Balanus reticulatus -is reduced via substrate pre-emption in the zone of overlap between the 2 barnacle species. A third barnacle, Balanus amphitrite, which invaded Hawaii earlier than the other two, is now virtually absent from locations where it was once abundant and where C. proteus is now the numerical dominant. B. amphitrite did not settle on plates from which C. proteus was removed, suggesting that the presence of C. proteus is not the proximal cause of its decline. B. amphitrite is still present on Oahu, particularly in lower salinity settings. While successively invading barnacles have reportedly replaced each other in other locations around the world, it appears that invasive barnacles on Oahu are undergoing niche compression rather than complete replacement.

In such interactions, larger, faster growing balanoid barnacles are likely to win over the typically smaller chthamaloid barnacles (Connell 1961b, Stanley & Newman 1980, Wethey 1984. Chthamaloid barnacles as a group tend to have a higher tolerance to air exposure, and where competition with balanoids is strong, may be relegated to the upper intertidal zone, where balanoids either do not settle or do not survive as well.Competition between barnacles can also occur via pre-emption of space. Some barnacle species tend to settle near conspecifics , Denley & Underwood 1979, Underwood & Denley 1984, but tend not to settle in already crowded conditions (Crisp 1961, Meadows & Campbell 1972, Gaines & Roughgarden 1985, Minchinton & Scheibling 1993. Thus, a barnacle species that arrives first and settles in abundance may have a competitive advantage over a second species that then encounters a crowded substratum and few conspecifics . Patterns of distribution and abundance of barnacle species that display strong conspecific settlement behavior should be governed, at least partly, by priority effects (sensu Paine 1977), and succession involving such barnacles might be expected to follow Connell & Slatyer's (...
