Journal of Chemical Ecology, 2005 The clover root weevil, Sitona lepidus, frequently feeds on N2 fixing rhizobial root nodules of white clover (Trifolium repens), which may contain isoflavonoids with defensive and plant regulatory properties. This study investigated the isoflavonoids present in N2 fixing (active) root nodules, root nodules that were not fixing N2 (inactive), and roots ...

Biological role of Nardonella endosymbiont in its weevil host. [PDF]
PLoS ONE, 2010 Weevils constitute the most species-rich animal group with over 60,000 described species, many of which possess specialized symbiotic organs and harbor bacterial endosymbionts. Among the diverse microbial associates of weevils, Nardonella spp.

Impact of Environmental Microparticles on Insect Olfaction
Environmental Toxicology, EarlyView.ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.

Development of clovers that are tolerant to clover root weevil
Proceedings of the New Zealand Grassland Association, 2005 Clover root weevil (CRW) has become a major pest of white clover in pastures in much of the North Island. In contemporary, intensively stocked pastures, high volumes of nitrogen (N) cycling through the soil/plant/ animal system stimulate grass growth and reduce the clover content of pastures. Clover root weevil imposes further stresses on clovers.

Root Deformation Reduces Tolerance of Lodgepole Pine to Attack by Warren Root Collar Weevil [PDF]
Environmental Entomology, 2010 Surveys were conducted on regenerating stands of lodgepole pine to determine the relationship between root deformation and susceptibility to attack by the Warren root collar weevil, Hylobius warreni Wood. The total number of trees attacked by H. warreni did not differ between planted and natural trees.

Insect Science, EarlyView.Moderate retention forestry creates structurally sharp forest edges that act as ecological filters, shaping orientation‐specific activity of ground‐dwelling arthropods. Using drift‐fence pitfall traps, we show that activity aligned with ecotones is more frequent than activity across forest–clearcut boundaries, particularly among detritivores.

Prospects of the use of wild relatives for pea (Pisum sativum L.) breeding
Вавиловский журнал генетики и селекции, 2015 The current global climate change results in shift and shrinkage of ranges of crop cultivation. The potential of crop wild relatives as an important source of genetic diversity for breeding is underestimated.
