The mass-specific metabolic rate decreases within and between instars (although the within instar decrease is not significant in the third instar).

open access: yes, 2013
At the beginning of each instar, the supply structures are not constraining, so this decrease is most likely due to a decrease in intrinsic oxygen demand.

Brood parasitism reduces but does not prevent Bombus terrestris reproductive success

open access: yesInsect Science, EarlyView.
Graphical depiction of the colony splitting process. Throughout figures in this paper, results pertaining to host success are represented in blue, and cuckoo success is represented in red. Abstract Cuckoo bumblebees are obligate brood parasites that must invade a colony of their host bumblebee species in order to reproduce.

LsFAMeT and LsJHAMT coordinate JH biosynthesis to regulate fecundity in Laodelphax striatellus

open access: yesInsect Science, EarlyView.
The small brown planthopper (SBPH), Laodelphax striatellus, can trigger large‐scale outbreaks when encountering suitable habitats during migration due to their strong reproductive ability. This study investigated the role of juvenile hormone (JH) in regulating SBPH reproduction.

Adaptation of the invasive pest Drosophila suzukii to a specialized nutritional niche

open access: yesInsect Science, EarlyView.
Unlike most Drosophila larvae that feed on spoiled food, Drosophila suzukii larvae thrive on ripening fruits and consequently face a low‐protein, high‐carbohydrate nutritional challenge. Comparisons of growth among D. suzukii, D. biarmipes, and D. melanogaster larvae across diets with varying protein‐to‐carbohydrate ratios demonstrate that D.

Age-specific interaction between the parasitoid, Encarsia formosa and its host, the silverleaf whitefly, Bemisia tabaci (Strain B)

open access: yesJournal of Insect Science, 2003
The effect of hostage, the instar of Bemisia tabaci (Gennadius) parasitized, on the growth and development of Encarsia formosa (Gahan) was studied. E. formosa was able to parasitize and complete its life cycle no matter which instar of B.

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum

open access: yesInsect Science, EarlyView.
RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.

Climatic conditions, landscape, and habitat quality drive patch occupancy and larval density of a threatened mire butterfly

open access: yesInsect Science, EarlyView.
The Moorland Clouded Yellow (Colias palaeno) benefited from cattle grazing in three different ways by (i) fostering the nectar supply; (ii) enhancing rejuvenation of the host plant (Vaccinium uliginosum); and (iii) improving microclimatic conditions for successful development of the immature stages.
