Tadpole shrimp are pests of rice production systems in California and have recently been found impacting Missouri and Arkansas rice fields. The shrimp feed on rice seedlings and uproot them during foraging, and their foraging behavior causes water to become muddy, which reduces light penetration to submerged seedlings and delays the development of the rice plant. In "Review of a New Pest of Rice, Tadpole Shrimp (Notostraca: Triopsidae), in the Midsouthern United States and a Winter...

To slow resistance of western corn rootworm beetles to genetically protected crops, much larger 'refuge' acreages of conventional crops have to be planted, 2 experts warn in a paper published in the Journal of Economic Ecology Genetically modified crops that produce insect-killing proteins from the bacterium Bacillus thuringiensis (Bt) have reduced reliance on insecticide sprays since 1996. These proteins are lethal to some devastating crop pests, but do not harm most other creatures...

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...

As acreage of row crops managed with conservation tillage increases, more growers are encountering slugs, elevating their importance as crop pests. Slugs can eat virtually all crops, and they are challenging to control because of the limited number of management tactics that are available. In "Slug (Mollusca: Agriolimacidae, Arionidae) Ecology and Management in No-Till Field Crops, With an Emphasis on the mid-Atlantic Region," a free, open-access article appearing in the Journal of...

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...
