Aquatic Symbionts: Assessing the Abundance of Torix Group Rickettsia in Aquatic Insects around the World

Symbionts are known to be an important aspect of almost every living organism. Invertebrates are no exception. They display a remarkable range of symbiotic relationships with bacteria, which are capable of altering reproduction, defence against natural enemies, and play a role in nutrition. Up until now, most work has centred on a bacteria called Wolbachia which is commonly found in insects.

Wolbachia is relatively rare in Odonates (dragonflies and damselflies) and other aquatic insects, but recent work has suggested the presence of another similarly pervasive microbe. Our work has revealed that the bacterium Rickettsia is carried in 40% of midge species, and the Azure Damselfly (Coenargrion puella) can carry one or two strains of infection. Data suggests that Rickettsia is a common but underrepresented feature of freshwater invertebrates and our aim is to see how true this theory is.

Kew Gardens: Powdery Mildew Survey

Powdery Mildew

Powdery mildews commonly occur on garden plants, are unsightly, and can cause serious damage. To help understand how widespread powdery mildews are, both in terms of geography and hosts, the Royal Horticultural Society and University of Reading are working together to identify and map as many powdery mildews as possible over the next two growing seasons. You can help by supplying us with infected plant samples and in exchange we will do our best to tell you what mildew is infecting your plant.
