Root Weevils

open access: yes, 2018
Root weevils are a group of small, black-to-brown weevils that commonly damage ornamental and small fruit plants in Utah. This fact sheet tells how to identify them, their life history and habits, their management including chemical control for larvae, cultural control for adults, and chemical control for adults.

Green Oil‐in‐Water Nanoemulsions for Delivery of Phytochemicals With Pesticidal Activity for Sustainable Food Production and Safety

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT Green oil‐in‐water (O/W) nanoemulsions incorporating essential oils (EOs) and food‐derived compounds are gaining prominence as biopesticidal platforms that address the growing demand for sustainable agriculture, food safety, and reduced chemical inputs.

Use of Expert Elicitation to Quantify Pasture Losses and Economic Costs of Invertebrate Pests in South‐Eastern Australian Dairy Farms

open access: yesAustral Entomology, Volume 65, Issue 2, May 2026.
ABSTRACT Invertebrate pests cause considerable damage to pasture‐based production systems each year. However, their economic cost in industries such as Australian dairy has seldom been quantified due to the prohibitive cost and logistical challenges of measuring damage at regional scales.

Edge Effect on the Distribution of the Green Shield Bug Palomena prasina in Hazelnut Orchards, and the Role of Adjacent Habitats in Crop Colonization

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 5, Page 461-474, May 2026.
Spring–Summer spatial dynamics of Palomena prasina (L.) and potential IPM strategies. ABSTRACT Palomena prasina (L.) (Hemiptera: Pentatomidae), the green shield bug (GSB), is an important hazelnut pest in Southern Europe. Currently, its control focuses on insecticide spraying during the crop season. We hypothesized that, as for other pentatomid species,

Seasonal Changes in Chemical Composition of Eurasion Watermilfoil (Myriophyllum spicatum L.) and Water Temperature at Two Sites in northern California: implications for Herbivory [PDF]

open access: yes, 1999
We compared seasonal changes in Eurasian watermilfoil (Myriophyllum spicatum L.) characteristics and water temperature for a shallow poind in Davis, CA, and the Truckee River, near Tahoe City, CA. Tissue C and N were 15% lower in plants from the Truckee

Spectral Characterization of the Life Stages and Physiological Responses of Diatraea saccharalis Fabricius (Lepidoptera: Crambidae) Larvae Parasitized by Cotesia flavipes Cameron (Hymenoptera: Braconidae)

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 5, Page 436-452, May 2026.
Hyperspectral proximal sensing was used to characterize the life stages and physiological responses of Diatraea saccharalis and to detect parasitism by Cotesia flavipes. Distinct spectral signatures differentiated eggs, larval instars, pupae, and adults, as well as live, dead, and parasitized larvae.

Early Root Herbivory Impairs Arbuscular Mycorrhizal Fungal Colonization and Shifts Defence Allocation in Establishing Plantago lanceolata.

open access: yesPLoS ONE, 2013
Research into plant-mediated indirect interactions between arbuscular mycorrhizal (AM) fungi and insect herbivores has focussed on those between plant shoots and above-ground herbivores, despite the fact that only below-ground herbivores share the same ...
