Birch Leaves as a Minefield: Do Trichomes Mediate Neonate Caterpillar Site Selection?
Entomologia Experimentalis et Applicata, EarlyView.We investigated whether neonate Drepana arcuata caterpillars select leaf sites based on trichome distribution. Specifically, we assessed where larvae establish on leaves, quantified trichome distribution on leaves, and tested whether neonates avoid leaf trichomes. Neonates preferentially established and fed on areas with fewer trichomes, especially the

Nutritional Stress Modulates Developmental Thresholds in a Male Dimorphic Mite
Entomologia Experimentalis et Applicata, EarlyView.Global warming can alter nutrition during development, but whether this affects phenotype expression solely through changes in condition or also through developmental decision‐making remains unclear. In the male‐dimorphic bulb mite Rhizoglyphus robini, nutritional stress shifted the developmental threshold for fighter versus scrambler expression and ...

Direct control of perennial weeds between crops – implications for organic farming [PDF]
, 2012 Perennial weeds can be a major constraint to organic crop production in several North European 26 countries. Preventive and cultural control measures may not suffice when infestations with perennials 27 become severe.

Time‐Course of Attainment and Reversal of Thermal Acclimation in the Invasive Fall Armyworm
Entomologia Experimentalis et Applicata, EarlyView.Heat acclimation was elicited within minutes with stronger responses at higher temperatures while cold acclimation provided no measurable plastic benefit in the invasive fall armyworm. Prolonged high‐temperature acclimation enhanced heat tolerance and delayed reversal of physiological gains while reversal of acclimation was temperature‐dependent ...

Laser Weeding Technology in Cropping Systems: A Comprehensive Review
AgronomyWeed infestations pose significant challenges to global crop production, demanding effective and sustainable weed control methods. Traditional approaches, such as chemical herbicides, mechanical tillage, and plastic mulches, are not only associated with ...

Reducing weed infestation in winter wheat by sowing technique
, 2007 Hoeing can improve weed control in cereals but this requires wider row spacing of the crop. A spe-cific band row design may also ensure high crop yield and quality, especially at the conditions of organic farming.

Journal of Applied Entomology, EarlyView.ABSTRACT The pest status of pea aphid (Acyrthosiphum pisum H.) in faba bean (Vicia faba L.) cultivation has gained importance because it transmits Pea necrotic yellow dwarf virus (PNYDV), a novel nanovirus in Europe. This study evaluated two faba bean varieties, ‘Fuego’ and ‘GL Sunrise’, grown under sole crop (SC) and intercrop (IC) conditions with oat
