Released en masse, sterile Mexican fruit flies can undermine a wild population of the fruit-damaging pests so that fewer applications of insecticide are needed. But the irradiation used to sterilize the flies weakens them, hindering their ability to outcompete wild-type males for female mates. Now, U.S. Department of Agriculture (USDA) and collaborating scientists have devised a hormone therapy for making sterile flies "more macho," improving their chances of mating with female flies...

The EPA decision to phase out AZM by 2012 means tree fruit growers will need new management strategies 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...

Lee Rannals for RedOrbit.com A growing concern over the dwindling honeybee population has scientists working to try and pin down the culprits behind the decline in numbers, and new research suggests that an insecticide may be the cause. Researchers wrote in the journal Environmental Science & Technology that neonicotinoid insecticides have played a key role in killing off the pollinators. The University of Padua team said widespread deaths of honeybees have been reported since...

The coffee berry borer, Hypothenemus hampei (Ferrari), is considered one of the most serious pests in coffee plantations worldwide. Infestations of this small beetle are difficult to combat; most of the insect's lifecycle is completed inside coffee berries, making insecticide penetration and contact difficult. Female beetles bore holes into developing berries attached to the tree through the blossom scar and create ℠galleries´ where they remain and deposit their eggs. The...

Honeybee populations have been in serious decline for years, and Purdue University scientists may have identified one of the factors that cause bee deaths around agricultural fields. Analyses of bees found dead in and around hives from several apiaries over two years in Indiana showed the presence of neonicotinoid insecticides, which are commonly used to coat corn and soybean seeds before planting. The research showed that those insecticides were present at high concentrations in waste...

To prevent devastating insect pest outbreaks in rice that cause millions of dollars of damage, the International Rice Research Institute (IRRI) has called for a ban on certain insecticides in rice production as part of its new Action plan to reduce planthopper damage to rice crops in Asia. At a conference in Hanoi, Vietnam, IRRI brought together leaders in the rice industry to advance towards a “greener game plan” to manage brown planthoppers, which, without exaggeration, are...
