Characterization of the arthropod attack to Phaseolus vulgaris
(Lambert Academic Publishing, 2017)
The insect and other arthropod community associated to Phaseolus vulgaris L. var. aborigineus (Burkart) Baudet, a native bean from Argentina, potential source for improvement of cultivated varieties, was compared between ...
Community-wide responses to predation risk: Effects of predator hunting mode on herbivores, pollinators, and parasitoids
(2018-01-01)
1. Flower visitation by herbivores and pollinators often occurs simultaneously, but their potential contrasting responses to predation risk are rarely investigated in concert. Predator avoidance behaviour is common in ...
Insect abundance and damage on the deciduous Nothofagus macrocarpa increase with altitude at a site in the Mediterranean climate zone of Chile
(CIENCIAS, 2015)
An understanding of the spatial and temporal patterns of insect abundance and plant damage across altitudinal gradients and the mechanisms driving them is limited. Importantly, little is known in this area in relation to ...
Patterns of Plumericin Concentration in Leaves of Himatanthus tarapotensis (Apocynaceae) and Its Interactions with Herbivory in the Peruvian Amazon
(MDPI, 2022)
We explored the concentration patterns of the bioactive metabolite plumericin produced by Himatanthus tarapotensis (Apocynaceae) under different edaphic conditions and variations in rainfall intensity, as well as its ...
The plant hormone salicylic acid interacts with the mechanism of anti‐herbivory conferred by fungal endophytes in grasses
(Wiley Blackwell Publishing, Inc, 2018-02)
The plant hormone salicylic acid (SA) is recognized as an effective defence against biotrophic pathogens, but its role as regulator of beneficial plant symbionts has received little attention. We studied the relationship ...
Previous herbivory alerts conspecific gravid sawflies to avoid unsuitable host plants
(Cambridge University Press, 2019-12)
The willow sawfly, Nematus oligospilus (Förster), is a pest in Salix commercial forests and has been reported worldwide. Female adults must recognize a suitable host plant to oviposit, since her offspring lack the ability ...
Early perception of stink bug damage in developing seeds of field-grown soybean induces chemical defences and reduces bug attack
(John Wiley & Sons Ltd, 2015-11)
BACKGROUND: Southern green stink bugs (Nezara viridula L.) invade field‐grown soybean crops, where they feed on developing seeds and inject phytotoxic saliva, which causes yield reduction. Although leaf responses to herbivory ...
