Scaphoideus titanus fitness on grapevine varieties with different susceptibility to Flavescence dorée phytoplasma

open access: yesJournal of Applied Entomology, Volume 146, Issue 10, Page 1260-1271, December 2022., 2022
Abstract Scaphoideus titanus (Ball) is a Nearctic leafhopper (Cicadellidae: Deltocephalinae), monophagous on Vitis spp., naturalized in European vineyards since the 20th century. Following its introduction and establishment in Europe, S. titanus became the main vector of Flavescence dorée phytoplasma (FDp) to grapevine. FDp causes heavy economic losses

Feeding site location in birch aphids (Sternorrhyncha: Aphididae): The simplicity and reliability of cues

open access: yesEuropean Journal of Entomology, 2000
To establish the importance of different cues for feeding site location in aphids, two birch-feeding species were given access to leaves that were either orientated normally or inverted.

Noise pollution as a major disturbance of avian predation in Amsterdam

open access: yesWildlife Biology, EarlyView.
Trophic interactions play a key role in maintaining ecological balance. In urban environments, avian predation has been demonstrated to be particularly important due to its effects on community structure, pest control, and nutrient cycling. As humanity relies upon ecosystem services for sustenance, and with 70% of the global population projected to ...

Biological control of aphids in the presence of thrips and their enemies

open access: yesBioControl (Dordrecht), 2013
Generalist predators are often used in biological control programs, although they can be detrimental for pest control through interference with other natural enemies.

The functionality of arbuscular mycorrhizal networks across scales of experimental complexity and ecological relevance

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract One of the most prevalent symbioses on Earth is that formed between the majority of land plants and arbuscular mycorrhizal (AM) fungi. Through these intimate associations, AM fungi transfer soil nutrients to their plant hosts in exchange for photosynthetically fixed ...

Diversification linked to larval host plant in the butterfly Eumedonia eumedon

open access: yesMolecular Ecology, Volume 32, Issue 1, Page 182-197, January 2023., 2023
Abstract It is widely accepted that the relationship between phytophagous insects and their host plants influences insect diversification. However, studies addressed at documenting host‐associated genetic differentiation (HAD) and the mechanisms that drive reproductive isolation in host‐associated lineages (or host races) are still scarce relative to ...

Honeydew production and honeydew sugar composition of polyphagous black bean aphid, Aphis fabae (Hemiptera: Aphididae) on various host plants and implications for ant-attendance

open access: yesEuropean Journal of Entomology, 2005
The black bean aphid, Aphis fabae, is polyphagous and its life cycle involves seasonal migration between summer and winter host plants. The aphids are regularly tended by honeydew-collecting ants.

Quantification of avoidable yield losses in oilseed Brassica caused by insect pests [PDF]

open access: yesJournal of Plant Protection Research, 51(1): 38-43 (2011), 2017
A six year field study was conducted from 2001 2002 to 2006 2007 at Punjab Agricultural University, Ludhiana, India to study the losses in seed yield of different Brassica species (B. juncea, B. napus, B. carinata, B. rapa and Eruca sativa) by the infestation of insect pests. The experiment was conducted in two different sets viz. protected/sprayed and
