Consciousness and Sentience of Insects

Research environment

The School of Biological and Behavioural Sciences at Queen Mary is one of the UK’s elite research centres, according to the 2021 Research Excellence Framework (REF). We offer a multi-disciplinary research environment and have approximately 180 PhD students working on projects in the biological and psychological sciences. Our students have access to a variety of research facilities supported by experienced staff, as well as a range of student support services.

Prof Lars Chittka is an international research leader in insect cognition; he has over 270 publications, many in Nature and Science. The lab is furnished with cutting-edge technology and computing equipment. Further details about the lab can be found at: http://chittkalab.sbcs.qmul.ac.uk/

Training and development

Our PhD students become part of Queen Mary’s Doctoral College which provides training and development opportunities, advice on funding, and financial support for research. Our students also have access to a Researcher Development Programme designed to help recognise and develop key skills and attributes needed to effectively manage research, and to prepare and plan for the next stages of their career.

The supervisor, Lars Chittka has trained 30 PhD students, many of whom are now full professors at top international universities, since they receive outstanding training and have often published in leading international journals as part of their PhDs. 

Project description

Any project in the areas of competence of supervisor Lars Chittka is possible - please email him directly to discuss your ideas.

Possible areas include insect consciousness, sentience and cognition, its neural underpinning and welfare application. We work on various insect species such as bumblebees, honeybees, black soldier flies and crickets.

One possibility is to work on insect sentience and its welfare implications. Sentience is the capacity to have subjective experiences of affective states. Such experiences may include pleasure, pain, comfort, anxiety, joy, and others. The importance of sentience to animal ethics and welfare is clear and widely acknowledged. Insect farming is on the rise, presented by its supporters as a creative solution to the problem of feeding the world while combating climate change—but feared by critics to be an animal welfare catastrophe.

Recent work on bees (emotion-like states and cognitive biases, play behaviour, cross-modal object recognition, interval timing, metacognition and motivational trade-offs) points to a capacity for conscious experiences in these insects. There is fragmented evidence across insects to indicate there may be a substantial risk of pain-like experiences. Nonetheless, one of the perceived advantages of insect farming is that there are (supposedly) no ethical concerns. Globally, trillions of insects are slaughtered annually by methods such as microwaving, baking or boiling without anaesthesia; many are simply starved to death.

New evidence regarding the presence or absence of sentience would allow a better-informed debate, especially if the evidence concerned commercially important species. Jonathan Birch and colleagues have developed a framework, based on neuroscientific, pharmacological and behavioural criteria, for evaluating the evidence for sentience.

We propose to investigate two commonly farmed species for their capacity for pain experiences at various developmental stages:

  • (1) house crickets, the most-farmed hemimetabolous insect species, where juvenile stages differ mainly in size, not body plan or lifestyle
  • (2) black soldier flies, expected to be the most-farmed insect species in the next few decades, and representative of holometabolous insects with a distinct grub-like larval stage.

Positive results would warrant increased attention on the potential welfare risks posed by insect farming. Meanwhile, negative results (in well-powered experiments) might at least partly diminish ethical concerns about the mass-rearing of such insects.

Funding

This studentship is open to students applying for China Scholarship Council funding. Queen Mary University of London has partnered with the China Scholarship Council (CSC) to offer a joint scholarship programme to enable Chinese students to study for a PhD programme at Queen Mary. Under the scheme, Queen Mary will provide scholarships to cover all tuition fees, whilst the CSC will provide living expenses for 4 years and one return flight ticket to successful applicants.

Eligibility and applying

Applicants must be:
- Chinese students with a strong academic background.
- Students holding a PR Chinese passport.
- Either be resident in China at the time of application or studying overseas.
- Students with prior experience of studying overseas (including in the UK) are eligible to apply. Chinese QMUL graduates/Masters’ students are therefore eligible for the scheme.

Please refer to the CSC website for full details on eligibility and conditions on the scholarship. 

Applications are invited from outstanding candidates with or expecting to receive a first or upper-second class honours degree in an area relevant to the project, such as biology, psychology or neuroscience (or any subdiscipline of these). A masters degree is desirable, but not essential.

Applicants from outside of the UK are required to provide evidence of their English Language ability. Please see our English Language requirements page for details: https://www.qmul.ac.uk/international-students/englishlanguagerequirements/postgraduateresearch/   

Informal enquiries about the project can be sent to Lars Chittka at l.chittka@qmul.ac.uk 

Formal applications must be submitted through our online form by 31st January 2024 for consideration, including a CV, personal statement and qualifications. You must meet the IELTS/ English Language requirements for your course and submit all required documentation (including evidence of English Language) by 14th March 2024. You are therefore strongly advised to sit an approved English Language test as soon as possible. 

Shortlisted applicants will be invited for a formal interview by the supervisor. If you are successful in your application, then you will be issued an QMUL Offer Letter, conditional on securing a CSC scholarship along with academic conditions still required to meet our entry requirements. Once applicants have obtained their QMUL Offer Letter, they should then apply to CSC for the scholarship by in March 2024 with the support of the supervisor.

Only applicants who are successful in their application to CSC can be issued an unconditional offer and enrol on our PhD programme. For further information, please go to: https://www.qmul.ac.uk/scholarships/items/china-scholarship-council-scholarships.html
