- An amino-acid mixture can be both rewarding and punishing to larval Drosophila melanogaster
Summary: A 20-amino-acid mixture can be both rewarding and punishing, suggesting that oppositely valenced parallel memories for it could be established in maggots.
- Food-derived volatiles enhance consumption in Drosophila melanogaster
Summary: Fruit flies integrate diverse olfactory and gustatory cues to guide feeding decisions, including situations in which animals are confronted with stimuli of opposite valence.
- Visuomotor strategies for object approach and aversion in Drosophila melanogaster
Summary: Animals classify stimuli to generate appropriate motor actions; aversive responses to a small object in Drosophila melanogaster are driven in part by processes that elicit signed saccades with distinct dynamics and trigger mechanisms.
- Thermosensory perception regulates speed of movement in response to temperature changes in Drosophila melanogaster
Highlighted Article: Although flies modulate speed in response to temperature following the same dynamic as metabolic reactions, this response is controlled by the nervous system and not by a direct thermal influence on metabolism.
- Hormetic benefits of prior anoxia exposure in buffering anoxia stress in a soil-pupating insect
Summary: Prior anoxia exposure benefits organismal performance, increases lipid levels and reduces the oxygen debt compared with a singular exposure to anoxia in the Caribbean fruit fly.
- Flight control of fruit flies: dynamic response to optic flow and headwind
Summary: Measurement and characterisation of the dynamic flight response of fruit flies reveal that their flight controller weighs visual and wind stimuli approximately equally, to produce flight thrust and adjust the pitch of the abdomen.
- Drosophila females trade off good nutrition with high-quality oviposition sites when choosing foods
Summary: Flies uncouple feeding and egg-laying decisions to balance their diet and provide a nutritionally optimal environment for their progeny, indicating a certain complexity in the nutritional ecology of parent–offspring interactions.
- Arginine and proline applied as food additives stimulate high freeze tolerance in larvae of Drosophila melanogaster
Highlighted Article: Development of a laboratory technique that secures high survival of the tropical fly Drosophila melanogaster when most of its body water is frozen.
- The sexually dimorphic behaviour of adult Drosophila suzukii: elevated female locomotor activity and loss of siesta is a post-mating response
Summary: Elevated daylight activity of female Drosophila suzukii (spotted-wing Drosophila) is a post-mating response.
