Beyond adult models: Tribolium castaneum larval timekeeping reveals unexpected robustness and insights into circadian clock

open access: yesInsect Science, EarlyView.
Abstract Circadian rhythms are self‐sustained endogenous oscillations that are found in all living organisms. In insects, circadian rhythms control a wide variety of behavioral and physiological processes, including feeding, locomotion, mating, and metabolism.

Foraging by predatory ants: A review

open access: yesInsect Science, EarlyView.
This review focuses on ecological and behavioral characteristics of foraging in ants showing the wide diversity of cases. Most ants can feed on sugary substances, but some ground‐nesting species are strict predators. Except army ants during the nomadic phase, they are central‐place foragers that can recruit nestmates when necessary. They prey mostly on

A laboratory system for examining the influence of light on diel activity of stream invertebrates [PDF]

open access: yes, 2002
I describe a laboratory system for investigating the role of light as a proximate cue for diel changes in locomotor activity and vertical location on the substrate of stream macro-invertebrates.

Differences in within‐plant oviposition preferences and immature survival between Orius predators and the importance of spatial availability of prey

open access: yesInsect Science, EarlyView.
Orius predators oviposit endophytically, and plant characteristics play an important role in their oviposition choices. In this study, we show that oviposition preferences differ between species, and that these differences may correlate with juvenile performance.

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 ...
