Effects of Atmospheric Pressure Trends on Calling, Mate-Seeking, and Phototaxis ofDiaphorina citri(Hemiptera: Liviidae)

Sampling Methods for Detection and Monitoring of the Asian Citrus Psyllid (Hemiptera: Psyllidae)

“…Zagvazdina et al (2015) found that mean responses of D. citri males in mate-seeking bioassays decreased when barometric pressure rose or fell more than 1 standard deviation over a 24-h period. Stockton et al (2017) found that the female-odor attractiveness to male D. citri increases after successful mating.…”

“…Virgin adult males, 3 to 10-d old, were obtained from a colony reared using procedures described in Paris et al (2013). Experiments were conducted in a sound-and vibration-shielded anechoic chamber equipped with a video system enabling viewing and recording of male psyllid movement on the tree (Zagvazdina et al 2015). Each male was tested only once.…”

“…1). The accelerometer signals were recorded and analyzed as described in Zagvazdina et al (2015) and Mankin et al (2016).…”

Male Psyllids Differentially Learn in the Context of Copulation

“…While female produced odors attract males in D. citri , they have not been strictly defined as pheromones and innate mate attraction to odors is relatively weak [19]. In addition, psyllid responses to olfactory stimuli are highly variable and difficult to study due to sensitivity to changes in barometric pressure and other environmental factors, which are difficult to control [54]. This may explain why, in at least two cases, our analysis revealed mild to insignificant differences between treatment groups, despite large differences within groups.…”

A “Walker” Tool to PlaceDiaphorina citri(Hemiptera: Liviidae) Adults at Predetermined Sites for Bioassays of Behavior in Citrus (Sapindales: Rutaceae) Trees

“…Extensive research is being conducted to improve D. citri management and characterize its biology and behavior, frequently involving bioassays where individuals are placed at predetermined sites on a test citrus plant, e.g., by use of a small paintbrush (Wenninger & Hall 2007;Wenninger et al 2009;Hall et al 2011;Zagvazdina et al 2015), so that their activities can be observed under particular testing conditions. During bioassays, it has been observed that the psyllids may be disturbed by such handling and frequently jump from the brush or subsequently jump from the tree within a few seconds after placement with the brush.…”
