Predation on Artificial Caterpillars Varies With Vertical Stratification but Not Light Gradients in a Sugar Maple Temperate Forest

Entomologia Experimentalis et Applicata, EarlyView.
Predation pressure varies vertically, with highest arthropod predation in the understory and highest bird predation in the canopy. Light availability differs across vertical strata, but predation patterns are more strongly influenced by height and forest structure than by light gradients.

Leaf Extracts of Coffea racemosa Inhibit Trypsin Activity and Affect Larval Development in Spodoptera frugiperda and Diatraea saccharalis

Entomologia Experimentalis et Applicata, EarlyView.
Leaf extracts of Coffea racemosa inhibit digestive trypsins and impair the development of two major lepidopteran pests, Spodoptera frugiperda and Diatraea saccharalis. While both species showed significant enzymatic inhibition, biological responses differed markedly. D. saccharalis exhibited high mortality, whereas S.

The effect of controlled temperature and humidity on the effectiveness of chemical defoliation of Ligustrum vulgare L. and Spiraea bumalda Burv. shrubs

Acta Agrobotanica, 2015
The influence of 3 temperatures: 4°, 13°, and 22°C and of 3 humidities 50% r.h., 77% r.h. and 95% r.h. on the effectiveness of two defolians KJ and Mg(ClO3)2•6H2O was investigated in a phytotron.

Ecosystem Services Against Illegal Immigration: The Natural Control of the Migratory Butterfly Painted Lady (Vanessa cardui) by Cotesia vestalis (Hymenoptera, Braconidae) on Organic Soybean in Ukraine

Entomologia Experimentalis et Applicata, EarlyView.
In central Ukraine, the migratory butterfly Vanessa cardui emerged as a key pest of organic soybean during its outbreaks in 2019 and 2022. Despite early defoliation, crops recovered strongly due to high parasitism by Cotesia vestalis, reaching 100% in some fields.

Evaluation of Pelargonic Acid as a Sustainable Defoliant in Cotton (Gossypium hirsutum L.) Production

Agriculture
Cotton production faces sustainability challenges due to the lack of effective sustainable defoliants for mechanical harvesting, which constrains the expansion of organic cotton (currently 0.5% of global production).

The influence of KJ, CuSO4, and Mg(ClO3)2 on defoliation and subsequent frost resistance and growth of apple trees in nurseries

Acta Agrobotanica, 2015
In most cases 2-year-old trees of 3 cultivars responded better to defoliants than 1-year-old ones. Spraying with defoliants on September 25 - 28 was more effective than spraying 10 days earlier.
