Description We have investigated experimentally how the release of genetically modified insects might be compatible with the dominant mode of resistance management for genetically modified crops. We have shown that self-limiting GM insects developed by Oxitec can slow or reverse the evolution of resistance and explored the parameter range under which they are compatible. Experiments have shown that moderate release rates and small refugia can work well together btu that impact of the evolution of resistance are critically dependent on the fitness of GM insects and their offspring. Furthermore, we have explored the efficacy of different strategies for GM insect release in structured insect populations and in populations under heterogeneous selection pressure.
Exploitation Route This is the first thorough experimental validation of the value of self-limiting insects insects in resistance management. It confirms that this could be a novel and valuable tool for combating the evolution of resistance and indicates the critical parameters (refuge size, release ratios, transgene fitness costs and their dominance) that are crucial to deploying these tools.

Description Helped ADAS draft "Crop Action" document on control of diamondback moth during the 2016 outbreak: issue 29
Geographic Reach National 
Policy Influence Type Implementation circular/rapid advice/letter to e.g. Ministry of Health
Impact We anticipate that advice on the largest influx of a key Brassica pest for 40 years would have had some impact on farmer's ability to control this pest over that season, although these would be very hard to quantify

Sector Private 
PI Contribution My team will be engaged in producing mutants with increased virulence to resistant insect pests, as well as screening strain collections and toxin libraries for novel or improved isolates and proteins.
Collaborator Contribution The partner will be providing access to a sequenced strain collection as welll as to additional sequencing / molecular characaterization services.

Description Microbial ecology and insect fitness 
Organisation Oxitec Ltd
Country United Kingdom 
Sector Private 
PI Contribution We have produced preliminary data indicating that intestinal microbiota make a significant contribution to insect fitness, especially the ability to compete for mates. This could have significant implications for the Oxitec's technology and plans to release insects for pest population reduction.
Collaborator Contribution The partner Oxitec provided GM insects and made suggestions for protocols/ rearing methods.
Impact At the moment we are considering options for how to follow up on these data- this may mean applying for additional grant/studentship funding.

Form Of Engagement Activity Participation in an open day or visit at my research institution
Part Of Official Scheme? No
Geographic Reach National
Primary Audience Undergraduate students
Results and Impact The Penryn campus runs a series of open days throughtout the year designed to engage with prospective students and their families. This gives us a venue in which to talk about our research generally and that of the campus. In an event last summer, for instance, I discussed the recent invasion of diamond back moth and met with a local cabbage farmer and talked about pest control issues associated with this species.

Results and Impact We put out a press release relating to the 2016 diamonndback moth outbreak and since Cornwall is a Brassica growing region and this is a Brassica pest I also directly contacted local radio stations. This lead to a series of radio interviews on BBC Local Radio (Laurence Reed Show); Heart FM and was picked by the Mark Forrester show - a pick of local radio program broadcast nationally.

Results and Impact This is a children focussed event designed to build enthusiasm in a young / very young audience for science in general. The event is a series of Christmas themed talks- my contributution discussed gift giving in animals and bacteria and introduced the idea of unwanted presents and also touched on current antiobiotic resistance themes. As well as the regional audience parts of this show received some national media interest.
