The registration portal is open from 01-December-2023 to 21-July-2024.

In order to create an environment that allows each participant to enjoy this conference, we have established a "Code of Conduct". Please study it carefully before registering.

Furthermore, please note the "General Terms and Conditions" on which this conference is based.

We will treat your data, collected for registration, and fotos, taken during this conference, with the utmost care. Details can be found in the "Information on the processing".

As the organising committee of the 18th Symposium on Insect-Plant Relationships (SIP), held in Bielefeld in 2024, it is our fundamental mission to host an event for researchers to meet, connect, learn, share, inspire, and build knowledge. We believe that including a diverse range of voices that fully represent the diversity of the entire research community is essential for this mission.

Unfortunately, harassment at big events, including scientific congresses, is common. Therefore, we implemented a strict Code of Conduct to create a safe space where discrimination or harassment on the basis of your identity, sexuality, physical appearance, race, disability or age will not be tolerated. A Code of Conduct outlining expected and unacceptable behaviour, including the consequences of non-compliance, will help creating an environment where delegates can interact safely, with a free and open mind. All participants, including attendees, speakers, volunteers, staff and service providers are expected to abide by this Code of Conduct during all major (talks, poster sessions and breaks) and minor (social events, activities and excursions) events that are part of the SIP 2024.


Expected Behaviour

In order to create a stimulating atmosphere, all attendees should keep in mind the following:

  • Be respectful and considerate to all attendees, including presenters and event organisers
  • Listen when someone else tries to speak up, and be patient with people who are not very well-versed in English
  • People can have different opinions, and disagreement happens; it is okay to walk away from a conversation that is not fruitful or is becoming tense
  • Do not assume anyone’s gender identity, sexual preference, economic status, background, health status
  • Refer to people by their preferred gender pronouns
  • Get consent before posting pictures of people on social media
  • Respect presenters’ requests to refrain from sharing the contents of their presentations on social media or other public platforms. If presenters do not want their slides to be shared on media, we encourage them to include a logo indicating this in their presentation
  • Respect the rules and policies of the event venue, hotels and any other meeting places


Unacceptable Behaviour

We want to create an inclusive and safe environment for everyone, and in order to achieve this, we strongly refrain all attendees of the SIP 2024 from the following:

  • Harassment, bullying, micro aggressions, intimidation and/or insinuations that are hurtful
    • E.g. demeaning behaviour or speech such as personal insults, sexist, racist, homophobic, transphobic, ageist or ableist language
  • Inappropriate physical contact without consent and unwelcome sexual attention, including sexualised comments or jokes
  • Disruption during talks, poster sessions or discussions
  • Verbal comments that reinforce social structures of domination related to gender, gender identity and expression, sexual orientation, disability, physical appearance, body size, race, age, religion
  • Any form of physical or verbal abuse
  • Advocating for or encouraging any of the above behaviour


How to report unacceptable behaviour?

Unacceptable behaviour will not be tolerated at the SIP 2024. If you are being harassed or you observe someone else being harassed, please speak up and report the case. If you see something that you feel is inappropriate and contrary to the spirit of agreed-upon conduct, speak to the person(s) affected and remind the person(s) that there is a process they can access. To report any cases and get help, you can locate a member of the organising committee or the other team members at the congress site or write an email to one of them (;;; The team members at the registration/info desk can help you to find the members of the organising committee if needed. All reports made will be kept 100% confidential and our team members will be briefed how to deal with such situations. If you do not feel comfortable speaking to the members of the organising team, you can also contact one of the external groups/hotlines, such as:

  • “Frauennotruf Bielefeld” (women’s helpline Bielefeld): phone 0521-124248, homepage
  • Help telephone (several languages, twenty-four-seven available): phone 116 016, homepage



Participants asked to stop any harassing behaviour are expected to follow the request immediately. All complaints will be reviewed and investigated and will result in a response that is deemed necessary and appropriate to the circumstances. The conference organisers retain the right to take any actions to keep the event welcoming for all participants. This includes warning the offender, expulsion from the conference (without a refund), mediation with the complainant / victim of the complaint and the person alleged to have participated in harassing or discriminatory behaviour. To preserve both the safety and the confidentiality of the complainant / victim in the complaint, no specific action will be taken without consultation and approval.



With registration I confirm that I have read and agree to adhere to the Code of Conduct of the SIP 2024. I understand that the organising committee may take any actions they deem appropriate, including removing me from the event without a refund, if I fail to adhere to this Code of Conduct.

They may do so by sending an email that includes the ticket ID. Participants shall use the following contact details for this purpose:

Department of Chemical Ecology, Bielefeld University, Universitaetsstr. 25, 33615 Bielefeld, Germany,

The period shall commence following receipt of this instruction in text form, but not before conclusion of the contract and also not before fulfilment of the organiser’s information obligations in accordance with Art. 246 § 2 in conjunction with § 1 (1) and (2) EGBGB and its obligations in accordance with the first sentence of § 312g (1) BGB in conjunction with the first sentence of Art. 246 § 3 EGBGB. Timely dispatch of the withdrawal shall be sufficient to comply with the withdrawal period.

Consequences of withdrawal:

Following effective withdrawal, the services received by either party shall be returned and any benefits derived (e.g., interest) shall be surrendered. If the participant is unable to return or surrender the service or benefit received (e.g., benefits of use), or is only able to return or surrender it in part or in a deteriorated condition, they must compensate the organiser for loss of value in this respect. Any obligation to refund payments must be met within 30 days. This time limit shall commence upon dispatch of the notice of withdrawal for the participant and upon its receipt for the organiser.

End of the withdrawal policy

The organiser may cancel in particular up to 10 days before commencement of the event if the minimum number of participants as stated in the event description is not achieved.

If the culpable breach of a main contractual obligation is not due to gross negligence or intent, the organiser’s liability shall be limited to the amount of the foreseeable damage, at most to the amount of the participation fee; furthermore, liability for any consequential and indirect damage shall be excluded.

10.3. Liability for damage caused during the travel to and from the venues, as well as for any loss and accidents, shall be excluded.

This shall also apply to any claims arising from pre- and post-contractual obligations as well as to any statutory claims that are competing with any contractual or pre- and post-contractual claims.

12.2. If any individual provisions of this contract are or become invalid due to any circumstance that occurs at a later date, this shall not affect the validity of the remaining part of the contract. The invalid provisions of the contract shall be replaced by such provision that comes as close as possible to what the contracting parties would have intended, had they considered the matter in question. This shall apply accordingly if there are any gaps in this contract.

12.3. The place of performance shall be the organiser’s registered office.
