Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)

open access: yesInsect Science, EarlyView.
As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...

Hop Variety Trial: Results from Year Four [PDF]

open access: yes, 2014
Great interest has been kindled in producing hops in the Northeast. While hops were historically grown in the Northeast, they have not been commercially produced in this region for over a hundred years.

Effects of host plant on life-history traits in the polyphagous spider mite Tetranychus urticae

open access: yesEcology and Evolution, 2015
Studying antagonistic coevolution between host plants and herbivores is particularly relevant for polyphagous species that can experience a great diversity of host plants with a large range of defenses.

Understanding biological control function and trophic interaction dynamics of an artificially released predatory bug by DNA metabarcoding

open access: yesInsect Science, EarlyView.
This study investigated the dietary composition of Sycanus bifidus, a generalist predator of the assassin bug that is artificially released into citrus orchards, and uncovered its trophic structure across various pest species using metabarcoding‐based molecular gut content analysis.

The predatory behavior of ants: an impressive panoply of morphological adaptations

open access: yesInsect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Hop Pest Scouting Report [PDF]

open access: yes, 2016
During the 2016 growing season, the major pest challenges we encountered at the hop yard at the Borderview Research Farm in Alburgh, Vermont were two-spotted spider mite (Tetranychus urticae), potato leafhopper (Empoasca fabae), and hop downy mildew ...

A preventive strategy for the control of aphids in sweet pepper using lacewings and micrococcinelid beetles

open access: yesInsect Science, EarlyView.
Aphids pose a serious risk to horticultural crops. Current biocontrol strategies often fail due to the poor establishment of natural enemies when aphids are scarce. We evaluated the potential of two aphidophagous predators, Micromus variegatus and Scymnus interruptus, to be used as preventive biocontrol agents, released before aphid infestation.

Detection of Sugarcane yellow leaf virus and Sugarcane mosaic virus in arthropods collected from corn, sorghum and sugarcane in Florida [PDF]

open access: yes, 2019
In Florida, sugarcane (Saccharum spp.), Columbus grass (Sorghum almum), and grain sorghum (S. bicolor) are three hosts of sugarcane yellow leaf virus (SCYLV) and sugarcane mosaic virus (SCMV).

Toxicity of essential oils from Nordic plants against different pathogenic organisms and pests of cultivated plants

open access: yesAnnals of Applied Biology, EarlyView.
Plant essential oils (EOs) represent a potentially effective, safe, and eco‐friendly alternative to synthetic pesticides that cause negative effects for human health and the environment. The present study evaluated in airtight glass chambers the toxicity of vapours produced by EOs obtained from sweet gale, balsam poplar, Labrador tea, jack pine, and ...

Yellow canopy syndrome of sugarcane: A review of current knowledge and future research directions

open access: yesAnnals of Applied Biology, EarlyView.
Yellow Canopy Syndrome (YCS) is a complex issue affecting commercial sugarcane in Australia, first identified in Far North Queensland over a decade ago. It has spread across most cane‐growing regions in Queensland and poses a significant threat to the global sugarcane industry.
