“…High values of r m obtained for T. urticae on tested plants in this study are comparable or even higher to those on bean, cucumber, gerbera and cultivated already cultivars of tomato plants (Witul 1992, Witul & Kielkiewicz 1996, 1999. The value of total fecundity and egg to egg developmental time of T. urticae on Motelle plants are close to the values of parameters reported earlier for the carmine spider mite (T. cinnabarinus) known as mite species with higher reproductive potential than T. urticae on commercially available tomato plants (Kielkiewicz 1996a,b, Witul & Kielkiewicz 1999.…”

SummaryMi-1.2 gene contributes to the resistance of tomato plants against some species of herbivores (i.e. nematodes, aphids) that are sap-feeders. In this study, two genotypes of tomato (Solanum lycopersicum L. syn. Lycopersicon esculentum Mill.) plants with dominant (Motelle cv) and recessive (Moneymaker cv) Mi-1.2 alleles were evaluated as a host-plant to the two-spotted spider mite (Tetranychus urticae Koch, Acari: Tetranychidae). Plants were grown under glasshouse conditions. The effect of tomato genotypes on T. urticae bionomy was estimated on cut leaflets in controlled photoperiod, temperature and humidity (L/D=16/8 h; D/N temp.=23/20°C; RH=70%). Results of laboratory evaluation showed that both the bionomy and population parameters of T. urticae reached a very similar or even higher value on plants with dominant Mi-1.2 allele than on plants with recessive one. A relatively high value of T. urticae parameters on plants resistant to root knot nematodes indicates that the mite has potential to develop rapidly. This allows the mite population to reach the density causing marked damage to plant in a short time. It is concluded that the presence of Mi-1.2 gene product in tomato plants does not significantly affect the reproductive potential of T. urticae. Therefore, Mi-1.2 gene cannot be a satisfying source of plant resistance to this mite-herbivore generalist.

“…We can find also similar adaptations to different kind of foods in some tetranichid species. Tetranychus urticae for example prefer the bean plants to tomato while T. cinnabarinus prefers cucumber to tomato (Witul and Kielkiewicz 1999). Phytoseiid mites show also adaptations to different micro-habitats linked to different types of host plants (herbaceous, shrubby and arboreal) (Tsolakis et al 1997).…”

“…However, these studies also revealed that this outcome is reversed in the presence of pesticides, due to stronger pesticide resistance in T. urticae . In fact, any abiotic or biotic factor that affects the relative fitness of these two species, such as temperature 47 , host plants 55 , or natural enemies 56 , should also determine their persistence. Yet, no study so far aimed at disentangling the relative role of such factors in shaping competitive outcomes, let alone the role of different intrinsic factors.…”

Competition for food and negative interspecific sexual interactions (reproductive interference) have been identified as major drivers of species exclusion. These interactions likely do not act independently, as they often involve the same actors and may be modulated by the same underlying traits. However, how they determine competitive dominance when acting in combination has not yet been studied. Here, we address this issue using two closely related species, the spider mitesTetranychus urticaeandT. cinnabarinus. First, by measuring species interactions in small-scale experiments, we revealed that the strength and symmetry of reproductive interference between species changed in presence of food competition. Next, using a population model, we showed that such non-additive effects induce significant changes in predicted competitive outcomes, specifically, a change in priority effects from favouring the inferior competitor for food in the sole presence of reproductive interference to favouring the superior competitor instead. Finally, we confirmed the accuracy of the model predictions for short-term population dynamics in a large-scale experiment. Together, these lines of evidence show that food competition and reproductive interference have non-additive effects on the population dynamics of interacting species, and highlight the necessity of incorporating both mechanisms to better predict competitive outcomes.
