Drought stress modulates indirect defense via bottom‐up effects in tomato and wheat

open access: yesPest Management Science, EarlyView.
Different water regimes can have a significant impact on plant morphology and defense pathways in tomato and wheat, triggering multiple olfactory choices in biocontrol agents of key insect pests. These findings could be used to implement biocontrol strategies within the IPM context under a changing climate scenario.

Biological parameters of two syrphid fly species Ischiodon scutellaris (Fabricius) and Episyrphus balteatus (DeGeer) and their predatory potential on wheat aphid Schizaphis graminum (Rondani) at different temperatures

open access: yesEgyptian Journal of Biological Pest Control, 2019
Syrphid flies, Ischiodon scutellaris (Fabricius) and Episyrphus balteatus (DeGeer), are among the most common aphidophagous species in wheat growing areas of Punjab, Pakistan.

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.

The predators of aphids on apples in the region East Sarajevo (Bosnia and Herzegovina)

open access: yesPlant Protection Science
Predators of aphids on apples were studied during the growing season in 2021 and 2022 in the region of East Sarajevo, Bosnia and Herzegovina. Eleven predator species were found on eight apple cultivars in the colonies of three aphid species, Aphis spp ...

Influence of different densities and nymphal instars of Aphis gossypii (Hemiptera: Aphididae) on developmental time and feeding rate of larvae of Episyrphus balteatus (Diptera: Syrphidae) under greenhouse conditions [PDF]

open access: yesنامه انجمن حشره‌شناسی ایران, 2017
Several aphidophagous insects such as predators and parasitoids are known to respond positively to aphid infested plants. This  study was intended to evaluate the effect of different densities (40, 60, 80, 100) and nymphal instars (1st, 2nd, 3rd, 4th) of

Metabarcoding of Pollen Carried by Syrphids Reveals Novel Plant–Pollinator Interactions in a Protected Natural Area and Agricultural Sites

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.

Syrphids (Diptera, Syrphidae) and coccinellids (Coleoptera, Coccinellidae) occurring in Myzus cerasi (F.) (Hemiptera) colonies on Prunus avium L.

open access: yesFolia Horticulturae, 2011
During the sampling period, 243 syrphid larvae belonging to seven species were collected from M. cerasi colonies on P. avium. Episyrphus balteatus Deg. and Epistrophe eligans (Harr.) were the most numerous species amongst the materials gathered, followed

Do aphid endosymbiotic bacteria influence parasitoid searching behaviour through changes in aphid honeydew production?

open access: yesEcological Entomology, EarlyView.
Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.
