Suitability of plant tissues as food for insects varies from plant to plant. In lepidopteran insects, fitness is largely dependent on the host-finding ability of the females. Existing studies have suggested that polyphagous lepidopterans preferentially select certain host plant species for oviposition. However, the mechanisms for host recognition and selection have not been fully elucidated. Fo...

Chestnut blight is a devastating disease of Castanea spp. Mycoviruses that reduce virulence (hypovirulence) of the causative agent, Cryphonectria parasitica, can be used to manage chestnut blight. However, vegetative incompatibility (vic) barriers that restrict anastomosis-mediated virus transmission hamper hypovirulence efficacy. In order to effectively determine the vegetative incompatibility...

Broad-scale patterns of vegetation response to three centuries of human disturbance in the northeastern United States are well understood, but stand-scale (0.1–10 ha) interactions between land-use history and the ecological processes underlying these patterns are not. Enduring legacies of land-use history, though pervasive in modern forests, are not always obvious or intuitive, particularly in ...

Three commercial plant tannin and a yucca extract having different secondary compound profiles were simultaneously evaluated in vitro for their effects on ruminal methane gas production and rumen fermentation patterns of wheat forage. Overall objective was to quantify in vitro, the sources of tannins and dose levels of tannins and yucca extract on rate of gas production, ruminal fermentation, f...

Herbicides that are labeled for aquatic use often the foundation of vegetation management programs in United States because many these products, which registered by U.S. Environmental Protection Agency, effective, selective, and relatively inexpensive. Resource managers interested reducing synthetic herbicides considering alternative methods weed control. We evaluated effects acetic acid d-limo...

Experiments were conducted to study the effect of time planting on performance Chinese water chestnut in Mekong Delta Vietnam over a single investigation. Plants local clone planted early January, March, May, July, September, or November and grown for four months. During experiments, photoperiod ranged from 11.2 12.6 h. The average daily mean temperature across different cropping periods 27.70C...
