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, EarlyView.
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.

Responses of Fruit Flies (Diptera: Tephritidae) to Protein Bait Applied at Different Densities

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT The effectiveness of odour‐based lures for insects is related to their active space, the air volume around an odour source in which an insect will detect and move towards it. This principle applies to protein baits laced with toxicants that are used as either sprays or stations to suppress pest fruit fly populations.

The complete mitochondrial genome of Sympiezomias velatus (Coleoptera: Curculionidae)

open access: yesMitochondrial DNA. Part B. Resources, 2017
Here, we determined the complete mitogenome sequence of Sympiezomias velatus (Coleoptera: Curculionidae: Entiminae). This mitogenome was 15,592 bp long with an A + T content of 74.1% and contains 13 protein-coding genes (PCGs), 21 transfer RNA genes ...

Species composition of blow flies (Diptera: Calliphoridae) colonizing pig carcasses exposed to bifenthrin‐ and clothianidin‐containing products

open access: yesMedical and Veterinary Entomology, EarlyView.
High clothianidin concentrations prevented colonization, while bifenthrin showed a non‐significant trend of reduced fly abundance, indicating both insecticides may suppress blow fly activity on treated carcasses. Adult emergence rates were unaffected, with no statistically significant differences observed across insecticide treatments, suggesting ...

Summer Diapause of the Clover Leaf Weevil, \u3ci\u3eHypera Punctata,\u3c/i\u3e and Lesser Clover Leaf Weevil, \u3ci\u3eHypera Nigrirostris,\u3c/i\u3e in Wisconsin [PDF]

open access: yes, 2017
Low respiration rates, immobility, lack of feeding, and undeveloped reproductive systems confirmed a summer diapause in the overwintered and current-year adults of the clover leaf weevil, Hypera punctata, and lesser clover leaf weevil, Hypera ...

Rhizobia–Bean Symbiosis Increases Root Herbivore Attraction and Growth via Volatile Signals and Enhanced Nutrition

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT The symbiosis between nitrogen‐fixing rhizobia and plants is considered mutually beneficial, yet its indirect effects on other organisms remain understudied. We examined how rhizobia symbiosis in Phaseolus vulgaris influences the behaviour and performance of Diabrotica balteata larvae. Specifically, we tested larval preference for nodulated (R+
