Oxidative Damage, Energy Imbalance, and Behavioral Disruptions in Girardia tigrina Exposed to Treated Sewage Effluents

Environmental Toxicology, EarlyView.
ABSTRACT This study assessed the ecotoxicological effects of treated sewage on the freshwater planarian Girardia tigrina, integrating biochemical, energetic, and behavioral biomarkers. Planarians were exposed for 48 h to different concentrations of treated sewage (12.5%, 25%, 50%, and 100%) and compared to controls using commercial water and water from

Cytogenotoxic and Molecular Assessment of Pyrethrins on Non‐Target Allium cepa Roots

Environmental Toxicology, EarlyView.
ABSTRACT The pyrethrins, which form a part of naturally occurring insecticidal chemicals derived from chrysanthemum flowers, not only provide rapid knockdown of a broad spectrum of insect pests but are also widely used in integrated pest management due to a generally favorable safety profile, largely attributed to low mammalian toxicity.

Side effects of thiacloprid+deltamethrin, pirimicarb and pymetrozine on the black bean aphid parasitoid, Lysiphlebus fabarum Marshall (Hymenoptera: Aphidiidae) [PDF]

, 2017
Lysiphlebus fabarum Marshall is the main parasitoid of the black bean aphid, Aphis fabae Scopoli. Lethal and sublethal effects of thiacloprid+deltamethrin, pirimicarb and pymetrozine were evaluated on the parasitoid under laboratory conditions.

Effect of insecticide-impregnated dog collars on incidence of zoonotic visceral leishmaniasis in Iranian children: a matched-cluster randomised trial.

, 2002
BACKGROUND: Deltamethrin-impregnated dog collars reduce sandfly bite rates on dogs, and are effective in killing sandflies that attempt to feed. Because domestic dogs are the principal reservoir hosts of zoonotic visceral leishmaniasis, we tested whether

Impact of Environmental Microparticles on Insect Olfaction

Environmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.

Delayed cuticular penetration and enhanced metabolism of deltamethrin in pyrethroid-resistant strains of Helicoverpa armigera from China and Pakistan

, 2006
The penetration and metabolism of [C-14]deltamethrin was studied in susceptible and resistant Chinese and Pakistani strains of Helicoverpa armigera (Hubner), which were resistant to deltamethrin by 330- and 670-fold, respectively.

Biology, ecology and dynamics of Deborrea malgassa (Heylarts 1884) (Lepidoptera: Psychidae), the main threat to apple Malus domestica Borkh growing in Madagascar

Agricultural and Forest Entomology, EarlyView.
Bioecology parameters of the endemic Psychidae Deborrea malgassa, the main pest of apple trees in Madagascar. Spatiotemporal dynamics of Deborrea malgassa, with a peak infestation between May and August. Proposed targeted prophylaxis techniques associated with other agroecological principles will be key to reducing the vulnerability of apple orchards ...
