Ecosystem services provided by spiders

open access: yesBiological Reviews, EarlyView.
ABSTRACT Spiders, ubiquitous and abundant predators in terrestrial ecosystems, often are the subjects of an unjust negative perception. However, these remarkable creatures stand as unsung heroes within our ecosystems, contributing a multitude of ecosystem services critical to human well‐being.

Keparahan Penyakit Daun Keriting Kuning dan Pertumbuhan Populasi Kutukebul pada Beberapa Genotipe Cabai

open access: yesJurnal Fitopatologi Indonesia, 2014
Incidence of yellow leaf curl disease on chili pepper is very common in Indonesia and becomes major production constrain. The causal agent, Pepper yellow leaf curl virus (PYLCV), is only transmitted by insect vector, i.e.

Genetic variation in zoophagy and dietary shift in the phytozoophagous tarnished plant bug, Lygus lineolaris

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Phytozoophagous insects such as Lygus lineolaris feed on plants and prey. This study assessed the genetic variability and heritability of zoophagy and dietary shift in 15 isofemale lines with access to Ephestia kuehniella eggs and with or without access to plant resources.

RESULTS OF THE THREE-YEAR MONITORING (2001.-2003.) OF TOBACCO WHITEFLY Bemisia tabaci (Gennadius, 1889), (HOMOPTERA: ALEYRODIDAE) IN CROATIA [PDF]

open access: yesPoljoprivreda, 2004
The quarantine pest tobacco whitefly Bemisia tabaci (Gennadius, 1889) was for the first time found in Croatia in 2000 on some culture and weed plants in greenhouses and in the open field in the area from Trogir to Omiš.

Ants do not prey upon an extrafloral‐nectar‐feeding predatory mite

open access: yesEcological Entomology, EarlyView.
The predatory mite Amblyseius herbicolus is an important natural enemy of various crop pests and occurs in agroforestry coffee systems, where it feeds on the extrafloral nectar of Inga trees. Because extrafloral nectaries are often vigorously defended by ants, we tested whether ants would attack and kill the mites near nectaries.

Molecular studies on the sweet potato virus disease and its two causal agents [PDF]

open access: yes, 2002
The studies presented in this thesis contribute to an increased understanding of the molecular aspects, variability and interaction of the two most important viral pathogens of sweet potato (Ipomoea batatas L): Sweet potato feathery mottle virus (SPFMV ...

Secoviridae: a proposed family of plant viruses within the order Picornavirales that combines the families Sequiviridae and Comoviridae, the unassigned genera Cheravirus and Sadwavirus, and the proposed genus Torradovirus [PDF]

open access: yes, 2009
The order Picornavirales includes several plant viruses that are currently classified into the families Comoviridae (genera Comovirus, Fabavirus and Nepovirus) and Sequiviridae (genera Sequivirus and Waikavirus) and into the unassigned genera Cheravirus ...

Aphid effector Mp10 balances immune suppression and defence activation through EDS1‐dependent modulation of plant DAMP responses

open access: yesNew Phytologist, EarlyView.
Summary Damage‐associated molecular pattern (DAMP)‐triggered immunity (DTI) serves as a crucial first line of defence against aphid attack, yet how aphids manage this response remains unclear. By investigating the colonisation of Arabidopsis thaliana by the highly polyphagous peach–potato aphid (Myzus persicae), we identified cell wall‐derived DAMPs ...

Planthopper protein Nlsp5 is essential for salivary sheath formation and acts as a HAMP inducing plant resistance to insects

open access: yesPlant Biotechnology Journal, EarlyView.
Summary During herbivore feeding, plants can recognize herbivore‐associated molecular patterns (HAMPs) present in saliva and trigger pattern‐triggered immunity (PTI). Piercing‐sucking insects secrete gel saliva, forming salivary sheaths that aid in feeding. However, the role of proteins within these salivary sheaths in modulating plant defences remains
