How does eye investment scale with body size and correlate with sensory specialization in Centris pallida males and females?

Zoos use a large number of feeder animals for nutritional and enrichment purposes each year. Should we care about their welfare and, if so, how?

Higher protein than wheat bran alone in larval diets increases growth, survival, and total yield and reduces cannibalism. The greatest benefits are seen when feeding high protein diets in the first four weeks of life, but larvae are benefited throughout the entire juvenile life stage. Adult fecundity also improves with protein supplementation either during the larval or adult stage.

Volumetric investment and cell number or density are decoupled in the optic lobes of male Centris pallida bees

Daily handling and pupation substrate choice affect development and adult morphology in BSF

A quick primer on farmed black soldier fly, house fly, and yellow mealworm welfare

How might semantic value associations have impacted the ecological study of parasites?

Continuing declines in the body size of wild desert bees.

New data confirm that adult black soldier flies can and do eat - and even have preferences for what nutrients they consume.

Eisemann et al. (1984) is still often cited as the authority on the neurobiological and behavioral arguments against pain in insects. However, the last forty years of insect research demonstrate the empirical claims in the paper are out of date. How should we move our understanding of insect pain into the 21st century?

What do entomologists report about the ethical treatment of their test subjects?

Barrett and Fischer are interviewed on working with insects in research for the CITI podcast ‘On Research’ and discuss their new CITI course.

How humane can grinding as a method of slaughter be for farmed yellow mealworms?

Can insect physiology tell us when farmed insects are doing well or poorly? Johnson and Barrett (2025) discuss!
