The first report of M918L (super‐kdr) and L932F voltage‐gated sodium channel mutations in the English grain aphid (Sitobion avenae)

Pest Management Science, EarlyView.
The study has identified mutations in the voltage gated sodium channel of the English grain aphid (Sitobion avenae) at M918 and L932, which have not been previously reported in this species. Abstract BACKGROUND The grain aphid, Sitobion avenae Fabricius (Hemiptera: Aphididae), is a vector of yellow dwarf viruses and an important pest of cereals.

Praon volucre (Hymenoptera: Braconidae: Aphidiinae), a natural enemy of Macrosiphum euphorbiae (Hemiptera: Aphididae): Life table and intrinsic rate of population increase

European Journal of Entomology, 2011
Life table data of natural enemies are often used to understand their population dynamics and estimate their potential role in the biological control of pests.

Sublethal herbicide exposure alters cotton susceptibility to aphid infestation

Pest Management Science, EarlyView.
Sublethal herbicide exposure altered cotton susceptibility to aphids. Aphid severity was highest when applications occurred at early vegetative stages and declined as the crop matured. In glasshouse, herbicide effects were dose‐dependent. Abstract BACKGROUND Herbicides remain vital tools for weed control, yet their effects can extend beyond weeds to ...

Relation between plant water status and Macrosiphum euphorbiae (Hemiptera: Aphididae) population dynamics on three cultivars of tomato

European Journal of Entomology, 2013
Deficit irrigation scheduling is used to increase the efficiency with which water is used in many crops including tomato, however a water deficit is predicted to favour phloem feeding insects.

RNA interference of the ecdysone receptor gene AgEcR in a wolfberry ‐ specialized strain of Aphis gossypii Glover affects its survival and fecundity and confers resistance in transgenic goji (Lycium barbarum L.)

Pest Management Science, EarlyView.
AgEcR, an ecdysone receptor from Aphis gossypii, is an RNA interference (RNAi) target. Artificial diet screening of five double ‐ stranded RNA fragments identified dsAgEcR2 targeting the D/E junction as the most potent. Transgenic goji expressing dsAgEcR2 caused molting defects and reduced fecundity, suppressing population growth and offering a ...

Tissue location of resistance in apple to the rosy apple aphid established by electrical penetration graphs [PDF]

, 2009
A study of the constitutive resistance of the apple cultivar Florina, Malus domestica Borkh. (Rosaceae), to the rosy apple aphid, Dysaphis plantaginea (Passerini) (Homoptera Aphididae), was performed for the first time by the electrical penetration graph

The degree of protection different ants (Hymenoptera: Formicidae) provide aphids (Hemiptera: Aphididae) against aphidophages

European Journal of Entomology, 2012
Aphids play an important role in the life of many ant species supplying them with energy-rich carbohydrate food and in exchange receiving some degree of protection from natural enemies.

Cascading bottom‐up effects of invasive alien plants on the parasitoid Aphidius colemani mediated by the aphid host Aphis fabae

Pest Management Science, EarlyView.
Differences in the suitability of invasive alien plants as hosts drove variations in cascading bottom‐up effects in aphid host and parasitoid performance, potentially influencing top‐down regulation. Abstract BACKGROUND Invasive alien plants (IAP) can threaten biodiversity by disrupting trophic interactions and, consequently, affect agroecosystems by ...

African Aphididae

Bulletin of Entomological Research, 1914
Our knowledge of the Aphididae of Africa is as yet very limited, this important group of insects having been but little studied, except in Europe and North America. At present only thirty-five species are recorded for the whole African continent, about the number one can collect in a single afternoon in one's own garden in England.
