Isolation and characterization of a novel lectin gene, Allium triquetrum agglutin, conferring insecticidal properties against Myzus persicae

, 2009
Myzus persicae, more commonly known as green peach aphid, is an important pest in agriculture. Each year it causes great losses to agricultural and horticultural plants. It feeds on sap in the phloem, the main transportation route for plant nutrients. It

Aphid Infestation and Predator Dynamics in Cultivated Ruta chalepensis: Evidence of Myzus persicae Adaptation and Natural Enemy Responses

Insects
Ruta chalepensis (Rutaceae), commonly known as rue, is traditionally recognized for its medicinal applications and cultural associations with mysticism. In addition to its ethnobotanical relevance, R.

Analogous pleiotropic effects of insecticide resistance genotypes in peach-potato aphids and houseflies

, 2003
We show that single-point mutations conferring target-site resistance (kdr) to pyrethroids and DDT in aphids and houseflies, and gene amplification conferring metabolic resistance (carboxylesterase) to organophosphates and carbamates in aphids, can have ...

Potato virus Y transmitting aphids in a Finnish seed potato area [PDF]

, 2009
The aphid-transmissible Potato virus Y is a major problem in seed potato production (Valkonen , 2007). The aphid flight activity was monitored from mid-June to the end of August with a suction trap and with yellow pan traps in 2007 and 2008 ...

Environmental change and the phenology of European aphids

, 2007
Aphids, because of their short generation time and low developmental threshold temperatures, are an insect group expected to respond particularly strongly to environmental changes. Forty years of standardized, daily data on the abundance of flying aphids

Barley yellow dwarf epidemiology [PDF]

, 2006
Barley yellow dwarf (BYD) disease is induced by viruses that are vectored by aphids. The viruses infect grasses and cause severe damage on oats, barley and wheat worldwide.

Improved preparation of (e)-beta-farnesene and its activity with economically important aphids

, 1982
(E)-β-Farnesene, the major component of the alarm pheromone of many aphids, is prepared in 65% yield by passing commercial nerolidol through an evacuated column of alumina, treated with pyridine, at 200° C.

Managing Friends and Foes: Sanctioning Mutualists in Mixed‐Infection Nodules Trades off With Defense Against Antagonists

Evolutionary Applications
Successful plant growth requires plants to minimize harm from antagonists and maximize benefit from mutualists. However, these outcomes may be difficult to achieve simultaneously, since plant defenses activated in response to antagonists can compromise ...
