Selection, counterselection, and conditional gene expression for genetic biocontrol of insects

Insect Science, EarlyView.
Selection, counterselection, and conditional expression can be used for sex separation. Selection (S) and counterselection (CS) genes are linked to the sex chromosomes (e.g., the X and Y chromosomes) to confer sex‐specific selection or counterselection based on the presence or absence of the S or CS genes.

The pesticide dieldrin disrupts proteins related to oxidative respiration and mitochondrial stress in the central nervous system

Data in Brief, 2017
Quantitative proteins analysis was carried out in the hypothalamus of zebrafish following dietary exposure to the legacy pesticide dieldrin. Data were collected using iTRAQ labeling methodology and data were acquired using a hybrid quadrupole Orbitrap (Q

Excretion of Dieldrin in the Milk of Cows Fed Dieldrin-Sprayed Forage and Technical Dieldrin

Journal of Dairy Science, 1954
Summary Dieldrin was detected in the milk of four cows when fed liay made from forage that had been sprayed with 3.5 and 7.0oz. of dieldrin per acre. The average daily dieldrin intakes were 0.10 and 0.75mg. per kilogram of body weight when the cows were fed the hays sprayed with 3.5 and 7.0oz. of dieldrin per acre, respectively.

Neoclassical development of genetic sexing strains for insect pest and disease vector control

Insect Science, EarlyView.
The sterile insect technique has been effectively used for decades, and an important component is the availability of sex separation systems, in particular genetic sexing strains. Classical approaches, such as irradiation‐induced chromosomal translocations, have yielded stable strains for species like the Mediterranean fruit fly.

Levels of organochlorine pesticides in the blood serum of agricultural workers from Rio de Janeiro State, Brazil Níveis de pesticidas organoclorados no soro sangüíneo de agricultores do Estado do Rio de Janeiro, Brasil

Cadernos de Saúde Pública, 1998
Serum levels of organochlorine pesticides (OCP) were measured in agricultural workers from Rio de Janeiro State, Brazil. Blood samples from 26 volunteers (24 males, 02 females, 17-60 years old) were taken in October 1997.

Facilitated Transport of Organic Contaminants in a High Concentration, Multicomponent Plume

Groundwater Monitoring &Remediation, EarlyView.
Abstract A field experiment evaluated the transport of organic contaminants in a plume from hazardous waste disposal areas at the Rocky Mountain Arsenal. The plume contained many xenobiotic contaminants, with widely varying expected mobilities.

The “Pesticide Chip”: Chemical Legacies and Agrarian Futures in Costa Rica

Antipode, Volume 58, Issue 2, March 2026.
Abstract For decades, agro‐industrial capital has adopted cascading chemical and biotechnical interventions, or fixes, to secure accumulation through the cultivation of monocrops. We develop a framework that centres on how monocrop‐induced susceptibility to pests and pathogens—and the patchwork of fixes to address these—produces uneven chemical ...

Synthesis, Characterization, and Evaluation of the Remediation Activity of Cissus quadrangularis Zinc Oxide Nanoparticle-Activated Carbon Composite on Dieldrin in Aqueous Solution

Journal of Nanotechnology, 2022
In this study, zinc oxide-activated carbon nanocomposite was used as the adsorbent for the remediation of dieldrin in aqueous media. Zinc oxide nanoparticles (ZNPs) were synthesized from Cissus quadrangularis (C.

Evaluation of the pollution pressures posed by groups of chemicals on British riverine invertebrate populations

Biological Reviews, Volume 101, Issue 1, Page 106-127, February 2026.
ABSTRACT Globally, rivers receive a diverse range of chemicals, including metals, pesticides, persistent organic pollutants, petrochemicals, human and veterinary pharmaceuticals and personal care products. However, the extent to which these different chemical groups affect riverine invertebrate communities is not well defined.
