Hypothesis
An immune challenge will induce sickness behavior in yellow mealworm beetles (Tenebrio molitor) and that the effect on behavioral expression will be dose- and age-dependent.
Conclusion
The study found little evidence that mealworm beetles experience sickness behavior, but older beetles were more active than younger ones.
Supporting Evidence
- Older beetles were found to be more active than younger ones.
- Little evidence was found that age, sex, and immune status affect behavioral variation among individuals.
- Beetles did not exhibit reduced activity or exploration after immune challenges.
Takeaway
Sick beetles usually act differently than healthy ones, but in this study, older beetles were actually more active than younger ones.
Methodology
The study used a repeated measures design to test the effects of immune challenges on beetle behavior.
Limitations
The study did not find significant effects of immune treatment on behavioral variation, which may limit the generalizability of the findings.
Participant Demographics
The study involved adult male and female yellow mealworm beetles, categorized into young and old age groups.
