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 ...

The Effects of Different Diets and Transgenerational Stress on Acyrthosiphon pisum Development. [PDF]

open access: yes, 2019
Despite the fact that sap-feeding hemipterans are major agricultural pests, little is known about the pea aphid's (Acyrthosiphon pisum) nymphal development, compared to other insect models. Given our limited understanding of A.

A preventive strategy for the control of aphids in sweet pepper using lacewings and micrococcinelid beetles

open access: yesInsect Science, EarlyView.
Aphids pose a serious risk to horticultural crops. Current biocontrol strategies often fail due to the poor establishment of natural enemies when aphids are scarce. We evaluated the potential of two aphidophagous predators, Micromus variegatus and Scymnus interruptus, to be used as preventive biocontrol agents, released before aphid infestation.

The Complete Mitochondrial Genome of Mindarus keteleerifoliae (Insecta: Hemiptera: Aphididae) and Comparison with Other Aphididae Insects [PDF]

open access: yesInternational Journal of Molecular Sciences, 2015
The mitogenome of Mindarus keteleerifoliae Zhang (Hemiptera: Aphididae) is a 15,199 bp circular molecule. The gene order and orientation of M. keteleerifoliae is similarly arranged to that of the ancestral insect of other aphid mitogenomes, and, a tRNA isomerism event maybe identified in the mitogenome of M. keteleerifoliae.

Effectiveness of aphid parasitoids (Hymenoptera: Aphidiidae) on winter wheat in two agricultural systems

open access: yesPlant Protection Science, 1999
From the obtained results we can note that the parasitoids in our experiments in 1 997 and 1998 had considerable influence on decline of aphids population density, at which the percent of parasitization in milk maturity stage of wheat was from 2.7 to 35%.

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

open access: yesInsect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

African Aphididae.—Part II. [PDF]

open access: yesBulletin of Entomological Research, 1915
The following notes and descriptions of African plant-lice are based mainly on part of the large collection I have received from Mr. F. C. Willcocks, made in Egypt since 1907 ; specimens from Mr. Gerald Bedford, collected in the Transvaal and the Cape ;and a small collection of spirit specimens without any colour notes sent to the ImperialBureau of ...
