author keywords: 454 pyrosequencing; leptin receptor; adiponectin receptor; G protein-coupled receptor; neuropeptide Y receptor; CAPA receptor; tachykinin precursor; proprotein convertase; furin; Hemiptera; Miridae; transcriptome analysis
topics (OpenAlex): Insect Resistance and Genetics; Viral Infectious Diseases and Gene Expression in Insects; Insect-Plant Interactions and Control
TL;DR: Overall transcriptome analysis was organized according to the Gene Ontology consortium, enzyme commission, and InerPro using the Blast2GO® program, and characterized metabolic systems and messages associated with development. (via Semantic Scholar)

Development of a rapid resistance monitoring bioassay for codling moth larvae

Magalhaes, L. C., Kretschmar, J. B. V., Barlow, V. M., Roe, R. M., & Walgenbach, J. F. (2011, December 9). Pest Management Science, Vol. 68, pp. 883–888.

By: L. Magalhaes n, J. Kretschmar n, V. Barlow n, R. Roe n  & J. Walgenbach n 

author keywords: Cydia pomonella; methoxyfenozide; insect resistance management; reduced-risk insecticides; diagnostic dose
MeSH headings : Animals; Animals, Newborn; Bacillus thuringiensis; Bacterial Toxins; Biological Assay / methods; Crops, Agricultural; Dose-Response Relationship, Drug; Drug Resistance; Gossypium; Insecticides; Larva / physiology; Lepidoptera / physiology; Reproducibility of Results; Time Factors
topics (OpenAlex): Insect Pheromone Research and Control; Insect and Pesticide Research; Insect-Plant Interactions and Control
TL;DR: It is demonstrated that a novel and rapid bioassay can be used to monitor for codling moth resistance to methoxyfenozide, and a single diagnostic dose, regardless of larval age, is only relevant to ingestion insecticides. (via Semantic Scholar)

2011 article

Life Stage Toxicity and Residual Activity of Insecticides to Codling Moth and Oriental Fruit Moth (Lepidoptera: Tortricidae)

Magalhaes, L. C., & Walgenbach, J. F. (2011, December 1). Journal of Economic Entomology, Vol. 104, pp. 1950–1959.

By: L. Magalhaes n & J. Walgenbach n 

author keywords: reduced-risk insecticides; baseline susceptibility; codling moth; oriental fruit moth
MeSH headings : Animals; Dose-Response Relationship, Drug; Female; Fruit; Insecticides / administration & dosage; Insecticides / chemistry; Insecticides / toxicity; Larva / drug effects; Larva / growth & development; Male; Malus; Moths / drug effects; Moths / growth & development; North Carolina; Ovum / drug effects; Ovum / growth & development; Pesticide Residues / chemistry; Pesticide Residues / toxicity; Species Specificity; Time Factors
topics (OpenAlex): Insect Pheromone Research and Control; Insect Resistance and Genetics; Insect and Pesticide Research
TL;DR: Ovicidal bioassays showed that oriental fruit moth eggs were generally more tolerant than codling moth eggs to insecticides, with novaluron, acetamiprid, and azinphoshmethyl having the highest levels of toxicity to eggs of both species. (via Semantic Scholar)

Cellulose Nanocrystals/Cellulose Core-in-Shell Nanocomposite Assemblies

Magalhães, W. L. E., Cao, X., & Lucia, L. A. (2009, September 4). Langmuir, Vol. 25, pp. 13250–13257.

By: W. Magalhães n, X. Cao n & L. Lucia n 

MeSH headings : Cellulose / chemistry; Dimethyl Sulfoxide / chemistry; Microscopy, Atomic Force; Models, Chemical; Models, Theoretical; Nanocomposites / chemistry; Nanocomposites / ultrastructure; Nanoparticles / chemistry; Nanoparticles / ultrastructure; Spectroscopy, Fourier Transform Infrared; X-Ray Diffraction
topics (OpenAlex): Advanced Cellulose Research Studies; Electrospun Nanofibers in Biomedical Applications; biodegradable polymer synthesis and properties
TL;DR: Surprisingly, it was determined that the physical properties for the cellulose controls are superior to the composites; in addition, the crystallinity of the controls was slightly greater. (via Semantic Scholar)

2009 article

Stimulatory Sublethal Response of a Generalist Predator to Permethrin: Hormesis, Hormoligosis, or Homeostatic Regulation?

Guedes, R. N. C., Magalhães, L. C., & Cosme, L. V. (2009, February 1). Journal of Economic Entomology.

By: R. Guedes *, L. Magalhães n & L. Cosme *

author keywords: dose response; fertility table; fitness; pest resurgence; natural enemy
MeSH headings : Animals; Female; Fertility / drug effects; Heteroptera / drug effects; Insecticides / administration & dosage; Oviparity / drug effects; Permethrin / administration & dosage
topics (OpenAlex): Plant and animal studies; Insect-Plant Interactions and Control; Insect and Pesticide Research
TL;DR: The stimulatory effect of sublethal doses of the pyrethroid permethrin topically applied to third instar nymphs of the spined soldier bug, Podisus distinctus (Stål) (Heteroptera: Pentatomidae), is reported, consistent with insecticide-induced hormesis, for which the potential implications are discussed.
