Fish and amphibians as test organisms for evaluation of effects caused by chemicals [PDF]

open access: yes, 2007
A large number of chemicals can contaminate aquatic environments and therefore be exposed to fish and amphibians during their sensitive stages of development.

Regulatory mechanisms of reproduction in locusts and grasshoppers

open access: yesNew Plant Protection, EarlyView.
Regulatory networks composed of numerous coding and noncoding genes play crucial roles in the reproduction of locusts and grasshoppers. This review integrates mechanistic advances in reproductive regulation, highlighting environmentally adaptive pathways and providing prospective targets for eco‐friendly pesticides.

The role of low levels of juvenile hormone Esterase in the metamorphosis of Manduca sexta

open access: yesJournal of Insect Science, 2001
The activity of juvenile hormone esterase (JHE) in feeding fifth instar larvae of Manduca sexta increases gradually with larval weight and rises to a peak after larvae pass the critical weight when juvenile hormone secretion ceases.

Juvenile hormone‐mediated accelerated post‐flight recovery of ovarian development in Loxostege sticticalis (Lepidoptera: Crambidae)

open access: yesNew Plant Protection, EarlyView.
Flight in female beet webworms (Loxostege sticticalis) promotes an increase in feeding, thereby enhancing abdominal energy reserves. Following flight, the flight muscles undergo accelerated histolysis, and the energy substances undergoing histolysis are redirected to the ovaries. These two processes collectively promote ovarian development.

Comparative Digital Estrogen Receptor Alpha (ERα) Expression Analysis in Benign and Malignant Prostate Tissue of Men and Dogs

open access: yesThe Prostate, EarlyView.
ABSTRACT Background The dog is the only large mammal, other than humans, that commonly develops spontaneous prostate cancer (PCa) and is, therefore, considered a valuable model for comparative studies. Estrogens are critical for normal prostate development and contribute to prostatic carcinogenesis in men.

Evolving resistance patterns in Tetranychus urticae and Bemisia tabaci in Greece

open access: yesPest Management Science, EarlyView.
Greek populations of T. urticae and B. tabaci exhibit evolving multi‐resistance, confirmed by bioassays and molecular markers, highlighting the urgent need for evidence‐based resistance monitoring in IPM. Abstract BACKGROUND Pesticide resistance in agricultural pests remains a major barrier to effective and sustainable crop protection.

From flower buds to bolls: how cotton reproductive structures shape boll weevil development, reproduction and survival

open access: yesPest Management Science, EarlyView.
Female boll weevils feeding on flower buds promote reproduction regardless of their immature diet, whereas boll feeding increases lipid reserves and lifespan, revealing a nutrition‐driven trade‐off that sustains survival and reproduction in tropical boll weevil populations.
