The Asian citrus psyllid is a major insect pest of citrus cultivars and vectors the bacteria that causes citrus greening disease. Recent research on a newly identified alternate host plant for Asian citrus psyllid examines the plant's potential as a trap crop for use in management of the pest.
Lab testing of the flight capability of the weevil Rhynchophorus palmarum shows some "super-flyers" can fly more than 100 kilometers in 24 hours. With the species appearing recently on both sides of the U.S.-Mexico border, the findings are a concern for California's $100 million date palm industry.
A food-grade gum substance shows promise as a new tool for managing the invasive spotted-wing drosophila. The flies don't get stuck, but the scent interferes with their reproductive behavior, and the gum can last up to three weeks in the field.
Sudden cold waves may be lethal to overwintering larvae of two parasitoid wasp species used for biological control of emerald ash borer, while the borer larvae appear to more easily weather the extreme cold.
