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

PLoS Neglected Tropical Diseases, 2017 Background Digestion of blood in the midgut of Aedes aegypti results in the release of pro-oxidant molecules that can be toxic to the mosquito. We hypothesized that after a blood meal, the antioxidant capacity of the midgut is increased to protect cells ...

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum
Insect 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.

Baculovirus Per Os Infectivity Factors Form a Complex on the Surface of Occlusion-Derived Virus [PDF]
, 2010 Five highly conserved per os infectivity factors, PIF1, PIF2, PIF3, PIF4, and P74, have been reported to be essential for oral infectivity of baculovirus occlusion-derived virus (ODV) in insect larvae.

Insect Science, EarlyView.Prostaglandin E2 (PGE2) signaling via its receptor has integral roles in mosquito physiology, mediating fluid excretion, stimulating hindgut contractions, and in modulating uric acid levels. Together, these results uncover previously unrecognized roles of prostaglandin signaling in osmotic balance and metabolic homeostasis in mosquitoes.

Matrine–Tea Saponin Synergism Involves Suppressed Detoxification and Digestion in a Leaf Beetle
Integrative Zoology, EarlyView.Tea saponin and matrine showed synergistic toxicity against Plagiodera versicolora. Combined exposure suppressed digestion‐ and detoxification‐related processes, while silencing the trypsin gene Pver105950 and chitinase gene Pver001190 increased larval susceptibility to tea saponin and matrine, respectively.

Midgut-derived NPF promotes mating-induced GSC proliferation.
, 2018 (A) The number of NPF-positive cells was dramatically reduced in the middle midgut of Tkg-GAL4>NPFRNAi animals. (B–D) Frequency of germaria containing 1, 2, and 3 GSCs (left axis) and the average number of GSCs per germarium (right axis) in virgin (v ...
