Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)

open access: yesInsect Science, EarlyView.
As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...

Understanding biological control function and trophic interaction dynamics of an artificially released predatory bug by DNA metabarcoding

open access: yesInsect Science, EarlyView.
This study investigated the dietary composition of Sycanus bifidus, a generalist predator of the assassin bug that is artificially released into citrus orchards, and uncovered its trophic structure across various pest species using metabarcoding‐based molecular gut content analysis.

Identification and characterization of a cucumber accession resistant to tomato leaf curl New Delhi virus

open access: yesAnnals of Applied Biology, EarlyView.
Tomato leaf curl New Delhi virus (ToLCNDV) causes significant yield and fruit quality losses in cucurbit crops, particularly in the Mediterranean region. We identified a new source of resistance to ToLCNDV in cucumber (accession ABS.PE.045) and mapped resistance to four genomic intervals in chromosomes 1, 2, 6, and 7.

siRNA Machinery in Whitefly (Bemisia tabaci)

open access: yesPLoS ONE, 2013
RNA interference has been emerged as an utmost tool for the control of sap sucking insect pests. Systemic response is necessary to control them in field condition. Whitefly is observed to be more prone to siRNA in recent studies, however the siRNA machinery and mechanism is not well established.To identify the core siRNA machinery, we curated ...
