A Multimodal Attract-and-Kill Device for the Asian Citrus Psyllid (Hemiptera: Liviidae).

Phytophagous insects, including Asian citrus psyllids ( Kuwayama), use multiple sensory modalities (vision, olfaction, and gustation,) to locate and accept host plants. We explored incorporation of several sensory cues into a multi-modal attract-and-kill device (AK device) using a three-dimensional shape to increase visibility, as well as elements of color, attractant, phagostimulant, UV reflectant, and toxicant. Attraction of adult to the device was mediated by a combination of a highly reflective yellow cylinder, a UV reflectant compound (magnesium oxide), and an odorant blend as a short-range attractant.

Feeding Behavior of Asian Citrus Psyllid [ (Hemiptera: Liviidae)] Nymphs and Adults on Common Weeds Occurring in Cultivated Citrus Described Using Electrical Penetration Graph Recordings.

Asian citrus psyllid, , transmits Liberibacter asiaticus (Las), the putative causal agent of Huanglongbing disease. Although they primarily feed on the phloem of and related plants, when grove or host conditions are unfavorable, . may be able to use weed species as alternate food sources for survival.
