Deleterious effects of the endosymbiont Rickettsiella viridis in Myzus persicae are environmentally dependent
Endosymbionts living within insect cells can modify host fitness and could provide new tools for pest control. The endosymbiont Rickettsiella viridis has been transferred experimentally into the green peach aphid, Myzus persicae, a globally important agricultural pest. This Rickettsiella spreads via vertical and horizontal transmission and induces host fitness costs which could potentially suppress pest populations. Endosymbiont prevalence can fluctuate in natural populations, and it is important to identify factors that contribute to their spread or loss. Here, we explore the effects of Rickettsiella infection when aphids are reared on eight different host plants or exposed to thermal, starvation and desiccation stresses. Rickettsiella infection reduced M. persicae fecundity and longevity across all host plants, but the magnitude of costs varied among host plants and generations. Rickettsiella was horizontally transmitted and spread in caged populations at initial ratios of 1:2 Rickettsiella (+): Rickettsiella (−) on all host plants, but with limited long-term persistence under cycling 20–30 °C. We also identified temperature-dependent costs of Rickettsiella infection on heat knockdown time, chill coma recovery, and starvation tolerance. Finally, we present evidence that Rickettsiella infection reduces host activity levels under heat stress. Our results suggest that Rickettsiella infections induce a variety of deleterious effects but with complex environment-dependent interactions. This work helps understand ecological conditions that enhance or limit the spread of these endosymbionts in aphid populations.
期刊介绍:
Journal of Pest Science publishes high-quality papers on all aspects of pest science in agriculture, horticulture (including viticulture), forestry, urban pests, and stored products research, including health and safety issues.
Journal of Pest Science reports on advances in control of pests and animal vectors of diseases, the biology, ethology and ecology of pests and their antagonists, and the use of other beneficial organisms in pest control. The journal covers all noxious or damaging groups of animals, including arthropods, nematodes, molluscs, and vertebrates.
Journal of Pest Science devotes special attention to emerging and innovative pest control strategies, including the side effects of such approaches on non-target organisms, for example natural enemies and pollinators, and the implementation of these strategies in integrated pest management.
Journal of Pest Science also publishes papers on the management of agro- and forest ecosystems where this is relevant to pest control. Papers on important methodological developments relevant for pest control will be considered as well.
