Mating activity of Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae) in nature [PDF]
European Journal of Entomology, 2019 The mating behaviour of Pyrrhocoris apterus in the laboratory is well studied, but little is known about it under natural conditions. In natural populations in Central Europe, overwintered adults start copulating in March and continue until their death ...

Dietary cardenolides enhance growth and change the direction of the fecundity-longevity trade-off in milkweed bugs (Heteroptera: Lygaeinae). [PDF]
Ecol Evol, 2021 We found that dietary cardenolides can increase growth, developmental speed, and longevity in milkweed bugs (Heteroptera: Lygaeinae). Abstract Sequestration, that is, the accumulation of plant toxins into body tissues for defense, was predicted to incur physiological costs and may require resistance traits different from those of non‐sequestering ...

Balancing Barcoding and Genomics: gDNA Quality in Insect Vouchers After HotSHOT DNA Extraction. [PDF]
Mol Ecol ResourABSTRACT DNA extraction with an alkaline buffer system called ‘HotSHOT’ is widely used for barcoding because it is rapid, inexpensive, and voucher preserving, but it remains unclear whether sufficient genomic DNA (gDNA) remains in small vouchers for downstream use in genomics.

Morphological structure of salivary glands, alimentary canal, and Malpighian tubules in adult Eurydema spectabilis Horváth, 1882 (Heteroptera, Pentatomidae). [PDF]
Microsc Res TechIn E. spectabilis, the salivary glands are divided into principal and accessory glands. Microvilli and numerous secretory granules were found in Malpighian tubules. Numerous uric acid crystals and bacteria were found in the rectum lumen. Abstract Eurydema spectabilis (Heteroptera: Pentatomidae) has a piercing‐sucking mouth type and feeds on plant sap ...

Effects of Crop Rotation Diversification and Livestock Integration on Above-Ground Arthropod Dynamics Under Conservation Agriculture. [PDF]
Ecol EvolDiverse crops in conservation agriculture systems can support a variety of arthropods, while sampling methods affected arthropod diversity outcomes. Canola‐Medics‐Wheat‐Medics rotation had a varied effect on arthropod diversity. We suggest that multiple taxa are necessary to compare diversification practices.
