“…Stimuli that might heighten male engagement would include the incorporation of known visual and olfactory attractants into the trap. For example, both males and females are attracted to flush (Catling 1970;Hall & Albrigo 2007;Sétamou et al 2016), light Pregmon et al 2016) and host odors (Patt & Séta-mou 2010;Hall et al 2015;Beloti et al 2017). Consequently, placement of trapping devices near flush at the outer edges of trees likely would result in higher trapping efficiency.…”

The Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae), vectors the bacterium causing citrus greening disease, which has devastated citrus production worldwide wherever it has been introduced. To help monitor and target D. citri populations in commercial groves, thereby facilitating more effective management of citrus greening disease, a prototype device has been developed that mimics D. citri female vibrational communication signals, attracting males to a trap. For this report, effects of the device on male D. citri searching behavior were assessed to consider potential improvements in field applications. Forty-five percent of the males that searched towards the female signal mimic reached the source. In addition, the mean latencies before the initiation of calling and searching responses by males that reached the source were significantly lower than for those that missed, which suggests that trapping efficiency is strongly influenced by variability in male responsiveness to searching cues. Consequently, it is likely that the trapping efficiency of vibration traps could be increased further if they were modified to make use of additional cues strongly attractive to males, such as citrus flush olfactory and visual cues.

“…The mechanisms by which D. citri locate flush shoots are not fully understood, but their positive phototropic behavior [8][9][10] assists in locating shoots on the outer branches, and the preference of females for young flush is known to be guided by assessments of tissue hardness [11,12] and chemical cues that vary with leaf age [13,14]. In addition, females are attracted to odors from feeding damage by conspecifics but, once on the tree, show preference for uninfested young flush in the presence of odors from feeding damage [15].…”

Adult Diaphorina citri (ACP) use visual and chemical cues to locate young citrus flush shoots on which they forage and oviposit, and they use vibrational communication duetting calls as cues to help locate mates. For individual pairs, calling and mating usually peaks between 10:00 and 15:00. To explore whether call rates (calls/h) are affected by interactions with nearby conspecifics, rates were compared in small citrus trees on which either 5 or 25 ACP female and male pairs had been released at 17:00 for later recording from sunrise (06:00) to 22:00. Final ACP locations were noted 40 h after release. Call rates were similar in both treatments during normal mating hours. However, rates were significantly higher for low- than high-density treatments between 06:00 and 10:00, which suggests calling during this period may be affected by conspecific density. Both sexes aggregated on flush at both densities. We discuss the potential that ACP producing calls near sunrise, outside of normal mating hours, might benefit from gains in reproductive fitness in low-density contexts if they call not only to locate mates but also to locate preferred flush—in which case, co-opting of vibrations to disrupt both mating and foraging may be feasible.
