Herbage accumulation dynamics in digit grass subjected to defoliation frequencies
Semina: Ciências Agrárias, 2019 This study was undertaken to examine the herbage accumulation dynamics and structural characteristics of digit grass subjected to different defoliation frequencies in the period of January 2015 to February 2016.

Environmental Stress Effects on Vigor, Mortality, and Growth in Northern Hardwood Forests Along a Pollution-Climate Gradient [PDF]
, 1998 Concern exists over the effects of interacting environmental stresses on the ecological integrity of temperate forests. Coincidence of sensitivity to drought, increasing occurrence of defoliation, and elevated pollutant deposition has produced ...

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.

Defoliation Frequency and Intensity of Arrhenathherum elatius [PDF]
This experiment was conducted with the aim of studying whether the frequency and intensity of defoliation of the temperate grass fromental (Arrhenatherum elatius (L.) Presl.) affected its total dry matter (DM)/ha yield as well as the seasonal ...

Foliar pests and pathogens of Eucalyptus dunnii plantations in southern Queensland [PDF]
, 2011 Eucalyptus dunnii is grown in plantations in subtropical Queensland, beyond its endemic distribution of northern NSW. As the plantation industry has expanded into subtropical Australia there has been an increase in the incidence of defoliating insects ...

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.

Responses of bahiagrass to nitrogen and defoliation
, 2003 Pensacola bahiagrass (Paspalum notatum Flgge) swards pretreated with fertilizer nitrogen rates of 0 and 66-99 kg N ha-1 year-1 were exposed to repeated, severe defoliation (i.e., removal of all laminae) of every day (D1), every 2 days (D2), and every 4 ...

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.

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
