Warm acclimation reduces the sensitivity of Drosophila species to heat stress at ecologically relevant scales

open access: yesJournal of Animal Ecology, EarlyView.
This study makes two key contributions to understanding thermal plasticity in ectotherms. First, we reveal non‐linear heat tolerance plasticity across species, challenging traditional linear assumptions. Second, we demonstrate that even subtle acclimation effects observed in the laboratory can significantly boost survival in natural environments ...

Processing of insect retrotransposons by self-cleaving ribozymes [PDF]

open access: yes, 2010
We show that several classes of insect non-LTR retrotransposons harbor self-cleaving ribozymes of the HDV family at their 5′ termini. In Drosophila the R2 ribozymes exhibit highly differential in vivo expression and robust in vitro activity ...

Evidence for transient deleterious thermal acclimation in field recapture rates of an invasive tropical species, Bactrocera dorsalis (Diptera: Tephritidae)

open access: yesInsect Science, EarlyView.
Abstract Knowing how environmental conditions affect performance traits in pest insects is important to improve pest management strategies. It can be informative for monitoring, but also for control programs where insects are mass‐reared, and field‐released.

Diet acts on sexual behavior development in a male moth

open access: yesInsect Science, EarlyView.
Drastic changes are observed during sexual maturation characterized by the reproductive system development concomitantly to the sexual behavior ontogenesis. These modifications are under the control of internal and external factors such as food. Knowing that sexual maturation requires considerable energetic investment, diet has been shown to affect ...

Microinjection‐enabled gene silencing in first instar larvae of western flower thrips, Frankliniella occidentalis, reveals vital genes for larval survival

open access: yesInsect Science, EarlyView.
This study introduces a microinjection technique to deliver dsRNA into the hemolymph of first instar larval thrips (L1s) via the foreleg coxa, enhancing survival rates by minimizing internal tissue damage. Significant knockdown of V‐ATPase‐B, CYP3653A2, and ApoLp‐II/I was achieved, with silencing of CYP3653A2 or ApoLp‐II/I increasing larval mortality ...

Anti-aging effect of brown black wolfberry on Drosophila melanogaster and d-galactose-induced aging mice

open access: yesJournal of Functional Foods, 2020
Aging is a global challenge. Many studies reported that the accumulation of ROS and oxidative stress could be the most important causative factors for aging. Phenolic, flavonoids, and melanoidins possess potent of ROS scavenging ability.

Innate preference in Drosophila melanogaster

open access: yesScience China Life Sciences, 2012
Innate preference behaviors are fundamental for animal survival. They actually form the basis for many animal complex behaviors. Recent years have seen significant progresses in disclosing the molecular and neural mechanism underlying animal innate preferences, especially in Drosophila.
