Azinphos-methyl (AZM) has been the most used insecticide in apple production in the United States since the late 1960s, primarily as a control for the codling moth, but a decision by the EPA to phase out AZM by 2012 signals the end of this product's use by tree fruit growers.
In recent years, many new insecticides have been registered to replace AZM. These new insecticides have unique modes of action, but growers will need to change their traditional management practices to achieve the level of control they were accustomed to with AZM, according to a new open-access article in the Journal of Integrated Pest Management.
In "Incorporating Organophosphate Alternative Insecticides into Codling Moth Management," scientists from Washington State University write about field trials conducted from 2004 to 2008 which explored new application timings and strategies that incorporated insecticides with different modes of action and targeted life stages.
The researchers found that the new insecticides could not provide fruit protection that was superior to the protection provided with AZM. However, strategies were developed that in many cases allowed equivalent control levels to those of the codling moth program based on AZM.
The most successful strategies employed insecticides that targeted both eggs (ovicides) and larvae (larvicides). An insect growth regulator applied at the start of the oviposition period, followed by two larvicide applications that targeted the peak egg-hatch period, provided fruit protection equivalent to the protection given by AZM applied twice.The full article is availabe for free at http://bit.ly/HWhQOQ.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
Over the last decade, there has been much excitement about the discovery, recognised by the Nobel Prize in Physics only two years ago, that there are two types...
What if a sensor sensing a thing could be part of the thing itself? Rice University engineers believe they have a two-dimensional solution to do just that.
Rice engineers led by materials scientists Pulickel Ajayan and Jun Lou have developed a method to make atom-flat sensors that seamlessly integrate with devices...
Scientists at the University of Stuttgart and the Karlsruhe Institute of Technology (KIT) succeed in important further development on the way to quantum Computers.
Quantum computers one day should be able to solve certain computing problems much faster than a classical computer. One of the most promising approaches is...
