Versatility of the trophic niche of Centris (Paracentris) burgdorfi (Apidae, Centridini)
Arthropod-Plant Interactions - Tập 13 - Trang 227-237 - 2018
Centris species collect floral oil and use this resource in larval food and for waterproofing their cells. We investigated the trophic niche of three distinct populations of Centris burgdorfi, a widely distributed bee in Brazil, by using pollen collected from female bees. Our goal was to determine whether there is versatility regarding sources of oil, nectar, and pollen in different regions of Bra...... hiện toàn bộ
Effects of nitrogen fertilization on tritrophic interactions
Arthropod-Plant Interactions - Tập 4 - Trang 81-94 - 2010
Tritrophic interactions (plant—herbivore—natural enemy) are basic components of nearly all ecosystems, and are often heavily shaped by bottom-up forces. Numerous factors influence plants’ growth, defense, reproduction, and survival. One critical factor in plant life histories and subsequent trophic levels is nitrogen (N). Because of its importance to plant productivity, N is one of the most freque...... hiện toàn bộ
How oilseed rape (Brassica napus) genotype influences pollen beetle (Meligethes aeneus) oviposition
Arthropod-Plant Interactions - - 2014
Oviposition of phytophagous insects is determined either by adaptive behaviours allowing evaluation and response to host plant quality and/or by nutritional constraints occurring during oogenesis. Besides differences found among host plant species, plant intraspecific diversity can also affect insect oviposition. However, to date few studies have extensively investigated the factors accounting for...... hiện toàn bộ
Inductive effects of exogenous calcium on the defense of kidney bean plants against Frankliniella occidentalis (Thysanoptera: Thripidae)
Arthropod-Plant Interactions - Tập 14 - Trang 473-480 - 2020
Calcium (Ca) is an essential macronutrient for plant growth. It can confer plants with resistance to abiotic stresses. However, little is understood about its role on biotic stresses. Frankliniella occidentalis (Thysanoptera: Thripidae) is one of the world’s most important invasive pests and poses a great threat to crops; meanwhile, it is hard to control due to its polyphagia and rapid reproductio...... hiện toàn bộ
Peptide fraction from latex of Calotropis procera exhibits antifungal and insecticidal activities
Arthropod-Plant Interactions - Tập 15 - Trang 431-438 - 2021
Latex is an endogenous fluid exuded by some plants after injury. It is rich in different molecules and has shown many biological activities against different fungi and insects. This work aimed to isolate a peptide fraction from Calotropis procera (PepCp) latex and to evaluate its activity against two fungi and an insect. The chromatographic profile showed that PepCp is constituted mainly by 7 kDa ...... hiện toàn bộ
The oviposition preference of Leucoptera coffeella is not determined by the cultivar of Coffea arabica, but it may influence some traits of its offspring performance
Arthropod-Plant Interactions - Tập 15 - Trang 563-571 - 2021
The coffee leaf miner, Leucoptera coffeella (Guérin-Méneville), is one of the main pests of coffee (Coffea spp.) in the Neotropical region. Leucoptera coffeella is considered a specialist insect because it develops exclusively within the leaves of the genus Coffea. In this laboratory study, we investigated the oviposition preference and performance of L. coffeella on the coffee leaf rust (Hemileia...... hiện toàn bộ
Differential parasitism by a generalist parasitoid is mediated by volatile organic chemicals of the herbivore’s host
Arthropod-Plant Interactions - Tập 9 - Trang 515-527 - 2015
A native parasitoid, Apanteles polychrosidis, shifted hosts to exploit the invasive leaf miner, Caloptilia fraxinella, on horticultural ash, Fraxinus spp. in Edmonton, AB, Canada. A. polychrosidis has the potential to control populations of the invasive leaf miner, and parasitism rates are studied on two host plants, black ash, F. nigra, and green ash, F. pennsylvanica. Parasitism by A. polychrosi...... hiện toàn bộ
Responses of butterflies to visual and olfactory signals of flowers of the bush lily Clivia miniata
Arthropod-Plant Interactions - Tập 15 - Trang 253-263 - 2021
Experimental studies of the use of visual and olfactory cues by flower-visiting animals can shed light on the evolution of floral signalling traits. We examined the functional significance of floral traits in Clivia miniata (Amaryllidaceae). This forest lily with large orange trumpet-shaped flowers is pollinated mainly by swallowtail butterflies and belongs to a lineage with ancestral bird pollina...... hiện toàn bộ
Interactive effects of light environment and herbivory on growth and productivity of an invasive annual vine, Persicaria perfoliata
Arthropod-Plant Interactions - Tập 6 - Trang 103-112 - 2011
Plant populations often exist in spatially heterogeneous environments with varying light levels, which can affect plant growth directly through resource availability or indirectly by altering behavior or success of herbivores. The plant vigor hypothesis predicts that herbivores are more likely to attack vigorously growing plants than those that are suppressed, for example in more shaded conditions...... hiện toàn bộ
