Insect meal use in aquafeeds: better than fishmeal? [PDF]

open access: yes, 2022
The use of insect-derived products in animal nutrition attracts great attention and shows a great opportunity for meeting the increasing feed raw materials demand. In the aquaculture sector, the interest about the use of insects as feed pushed the European Union to allow, in 2017, the inclusion of insect-derived protein from seven insect species in ...

Comparing Methods for Measuring Predation: Toward a Quantitative–Informative Indicator of Natural Pest Control

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Predation methods vary widely in their ability to quantify biological control. Estimating predation rates (the number of prey killed per predator per time unit) is crucial. Combining predation rates with predator abundance yields real‐time field estimates of pests consumed.

Environmental Stress Drives Plasticity in Sexual Bimaturism in the Black Soldier Fly (Hermetia illucens Linnaeus, 1758)

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We measured the plasticity in sexual bimaturism (SBM; differences between sexes in the timing of sexual maturity) in the black soldier fly (BSF) by exposing larvae to nutrient availability and humidity stress. Our results show that SBM can range between protandry and protogyny depending on the environmental quality. Additionally, we found the degree of

Challenges to artificial intelligence‐enabled digital technology adoption in farms: a multi‐method approach

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract Artificial intelligence (AI)‐enabled digital technologies have the potential to transform agriculture by supporting decision‐making and automating operations. However, their limited adoptions and scholars’ atheoretical explorations constrain our understanding.

Responses of Fruit Flies (Diptera: Tephritidae) to Protein Bait Applied at Different Densities

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT The effectiveness of odour‐based lures for insects is related to their active space, the air volume around an odour source in which an insect will detect and move towards it. This principle applies to protein baits laced with toxicants that are used as either sprays or stations to suppress pest fruit fly populations.
