Silencing of juvenile hormone‐related genes through RNA interference leads to molt failure and high mortality in the spongy moth

Insect Science, EarlyView.
The feasibility of using RNA interference to control the globally important quarantine pest, the spongy moth. Targeting genes related to JHs play an important role in the growth and development of insects. First, the open reading frames (ORFs) of Ldjhamt and Ldjheh were identified and characterized, and the target genes were cloned and double‐stranded ...

Offspring performance does not explain oviposition preference in the leafminer Stigmella sorbi (Lepidoptera: Nepticulidae): a tri‐trophic perspective

Insect Science, EarlyView.
We studied oviposition site selection in a leaf‐mining moth (Stigmella sorbi) on rowan trees (Sorbus aucuparia) in northwestern Russia, assessing larval performance across different shoot types, leaf positions, and leaflets. Larval survival was highest on long vegetative shoots, yet females showed no preference for these optimal sites.

Axillary bud viability and dry matter production of Poa ligularis in Patagonian grasslands [PDF]

, 2004
Poa ligularis Nees is one of the dominant perennial grass species in Patagonian grasslands. This is the first field study which investigated the effects of defoliation frequency on its number of viable axillary buds, and subsequent dry matter production ...

Herbage yield and quality of Gliricidia sepium under different cutting heights and defoliation frequencies

Agroforestry Systems, 1996
The browse shrub Gliricidia sepium, introduced into the subhumid zone of Nigeria to serve as a supplementary-forage source for ruminant during the dry season, has the undesirable characteristic of shedding its leaves during its flowering phase which coincides with the early dry season. This report relates a management practice undertaken to maintain G.

A Self-Calibrated Non-Parametric Time Series Analysis Approach for Assessing Insect Defoliation of Broad-Leaved Deciduous Nothofagus pumilio Forests

Remote Sensing, 2019
Folivorous insects cause some of the most ecologically and economically important disturbances in forests worldwide. For this reason, several approaches have been developed to exploit the temporal richness of available satellite time series data to ...

Differences in characteristics between naturalized threatened plants and other threatened plants

Conservation Biology, EarlyView.
Abstract Many non‐native plant species introduced by humans have become naturalized. At the same time many species are threatened in their native range. However, the number of plant species threatened in their native range that are naturalized elsewhere remains unknown.
