The First Haemolymph Analysis of Nhandu Chromatus Tarantulas — Biochemical Parameters
Folia Veterinaria, 2016 Tarantulas are a relatively unstudied category of invertebrate which are popular with hobbyists and increasingly used in laboratory research. As their presence in the veterinary setting is limited, very little is known about the biochemistry of their ...

PHYSIOLOGICAL SYMPTOMS INDUCED BY ECDYSONE AGONIST METHOXYFENOZIDE ON THE COTTON LEAFWORM, SPODOPTERA LITTORALIS (BOISD.) [PDF]
Arab Universities Journal of Agricultural Sciences, 2009 Newly ecdysed fourth instar larvae of the cotton leafworm, Spodoptera littoralis (Boisd.) were treated with LC50 of ecdysone agonist methoxyfenozide, to provide better insights into physiological symptoms and aspects induced by it as a mimic to the 20 ...

Life Cycle of \u3ci\u3eIsoperla Lata\u3c/i\u3e (Plecoptera: Perlodidae) in a Central Wisconsin Trout Stream [PDF]
, 2018 Monthly qualitative samples of Isoperla lata Frison were made from January 1992 to June 1993 in Ripley Creek, a small second order trout stream in Lincoln County Wisconsin. Additional collecting and an in-stream hatching experiment were conducted in 1994.

Molecular Ecology, Volume 35, Issue 4, February 2026.ABSTRACT Understanding how organisms respond to chemical stress requires disentangling genetically encoded (constitutive) adaptations from environmentally induced (plastic) responses. This challenge is particularly acute for polycyclic aromatic hydrocarbons (PAHs), widespread aquatic pollutants with well‐documented toxicity, where mechanisms of ...

SoxC is Required for Ecdysteroid Induction of Neuropeptide Genes During Insect Eclosion
Frontiers in Genetics, 2022 In insects, the shedding of the old exoskeleton is accomplished through ecdysis which is typically followed by the expansion and tanning of the new cuticle.
