Physiology of Plants Recovering from Defoliation [PDF]
Short-term, whole-plant physiological responses of forage plants to defoliation and the characteristics that allow them to rapidly replace lost tissues are the focus of this review.

Journal of Forest Science, 2002 A new method for evaluating damage caused by tenthredinids to Norway spruce stands is based on defoliation of the top whorls. A scale with four classes of defoliation was established that is easy to use. Defoliation can be displayed graphically on a grid

Entomologia Experimentalis et Applicata, EarlyView.We describe methods for collecting and rearing the tachinid parasitoid Istocheta aldrichi from parasitized Japanese beetle adults. Hosts can be collected by hand and reared in the laboratory, or by using modified trap containers with added plant material and substrate to provide suitable conditions for I.

Entomologia Experimentalis et Applicata, EarlyView.An integrated framework combining geometric morphometrics and ecological niche modeling was applied to Cydalima perspectalis to assess intergenerational morphological variation, test sexual dimorphism, and predict future distribution under climate scenarios. Wing shape effectively discriminated between generations but not between sexes.

PLoS ONE, 2014 BackgroundHerbivore grazing is a multiple-component process that includes wounding, defoliation, and saliva deposition. Despite the extensive published research on mechanical wounding and defoliation, no analysis to identify the genes that specify ...

Soybean response to weed interference and defoliation
, 1999 Field experiments were conducted in Louisiana over 2 yr to evaluate the influence of full-season interference from johnsongrass, common cocklebur, or hemp sesbania at densities of 2.5, 0.5, and 2.0 plants m-1 of row, respectively, and simulated insect ...

Entomologia Experimentalis et Applicata, EarlyView.Actia interrupta is a larval tachinid parasitoid that plays a key role in regulating low‐density populations of the eastern spruce budworm. We describe its immature stages, life‐history traits, host‐searching behavior, development, and confirm its larviparous reproductive strategy.

Effects of Invasive Winter Moth Defoliation on Tree Radial Growth in Eastern Massachusetts, USA
Insects, 2014 Winter moth, Operophtera brumata L. (Lepidoptera: Geometridae), has been defoliating hardwood trees in eastern Massachusetts since the 1990s. Native to Europe, winter moth has also been detected in Rhode Island, Connecticut, eastern Long Island (NY), New

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

Ecological Entomology, EarlyView.Mixed‐species plantations sustain tree‐dwelling arthropod diversity comparable to natural forests, with similar functional evenness but distinct species composition. Analyses of β‐diversity and LCBD highlight unique site contributions associated with reduced species and functional richness, as these distinct sites contain fewer yet more unique species.
