A Chemical Lure That Sticks: New Trapping Methods for Citrus Greening Pest

September 09, 2019
The Asian citrus psyllid is the bogeyman of the citrus industry. Its appearance in fields is a dark harbinger for farmers, for carried within this insect is the bacteria Candidatus Liberibacter, the cause of citrus greening disease. In a study published in Scientific Reports, UC Davis researchers report that an acetic acid-based, slow-release trap is capable of capturing Asian citrus psyllids even when the insect populations are low.

Why Insect Pests Love Monocultures, and How Plant Diversity Could Change That

October 17, 2016
Left to its own defenses, a farm field growing a variety of plants tends to attract fewer insect pests than a field growing just one type of crop. While scientists and farmers have noted that difference for years, the reasons behind it have been poorly understood. A study led by the University of California, Davis, and published Oct. 12 in the journal Nature explains that much of the discrepancy may have to do with the nutritional needs of insects.
