Hybridization and Immunology in Animals: A Review

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Hybridization can reshape immune function by introducing novel genetic variation and combining parental immune traits. Across animal taxa, this process may influence resistance, tolerance, and pathogen dynamics, with important implications for disease ecology and One Health.

DDT residues on sweet corn: Kernels and cob of corn treated with DDT remain practically free of residues but amounts on plant restrict use as fodder

open access: yesCalifornia Agriculture, 1956
Technical DDT at the rate of 4.5 to 12 pounds an acre—depending upon the method and number of applications—is applied to most of California's commercial sweet corn acreage to control the corn earworm.

Temporal Variation in Genetic Composition of Migratory Helicoverpa Zea in Peripheral Populations

open access: yesInsects, 2020
Migrant populations of Helicoverpa zea (Boddie) captured during 2002, 2005, 2016, and 2018 from Landisville and Rock Springs in Pennsylvania, USA were genotyped using 85 single nucleotide polymorphism (SNP) markers.

Glucosinolate hydrolysis products suppress entomopathogenic nematodes in vitro but do not protect sequestering flea beetle larvae in vivo

open access: yesPest Management Science, Volume 82, Issue 4, Page 3603-3612, April 2026.
The flea beetle's glucosinolate‐based chemical defense fails to protect larvae from nematode infection. However, the defense inhibits the nematode's symbiotic bacteria, thereby potentially impairing nematode reproduction and biocontrol success. Abstract BACKGROUND The efficacy of entomopathogenic nematodes (EPNs) in the biological control of insect ...

Soybean growth habit influence on development, yield, and seed quality in North Carolina full‐season soybean production

open access: yesAgronomy Journal, Volume 118, Issue 2, March/April 2026.
Abstract North Carolina soybean [Glycine max (L.) Merr.] production has historically relied on later maturing determinate varieties, but recent availability of later maturing indeterminate varieties has raised questions about growth habit effects on soybean production in the region. This study evaluated the impact of soybean growth habit (indeterminate

Caterpillar damage to tomatoes: Results based on one-year survey indicate no evidence of resistance to insecticides in nine commercial tomato fields

open access: yesCalifornia Agriculture, 1956
Suspected resistance to DDD and DDT in controlling caterpillars attacking tomatoes—the corn earworm, in particular—was investigated in San Joaquín County during the 1955 season.

A Volatile Cue From a Specialist Herbivore Primes Gene Expression Against Biotic Stress in Tall Goldenrod (Solidago altissima L.)

open access: yesPlant, Cell &Environment, Volume 49, Issue 3, Page 1424-1438, March 2026.
ABSTRACT Insect‐derived molecular cues can prime plant defences against herbivore attack. The genes that are sensitive to priming, and how their expression changes on the scale of days, have not been fully resolved. Moreover, priming may affect interactions with insects that are not the source of the priming cue.

Control of the corn earworm on sweet corn in Southern California

open access: yesCalifornia Agriculture, 1975
The corn earworm, Heriothis zea (Boddie), also known as he tomato fruitworm and cotton bollworm, is a serious pest on weet corn, tomato, cotton, and several other row crops grown commercially in California. Sweet corn, however, is the preferred host and,

The Perceptions and Knowledge of Farmers on Sustainable Pest Management in Three Agricultural Production Systems in Tungurahua Province, Ecuador

open access: yesAdvances in Agriculture, Volume 2026, Issue 1, 2026.
The overreliance on chemical pesticides in Ecuadorian agriculture raises serious concerns regarding environmental sustainability and public health. This study aimed to assess farmers’ perceptions and knowledge of sustainable pest management strategies across three agricultural systems in Tungurahua province: indigenous family farming (Salasaka), fruit ...
