“…In contrast, nymphs seem not to be repelled by P. persica plants because they initiated stylet penetration behavior as fast as that observed on P. insititia. This is in accordance with recent findings from olfactometer assays, showing that C. pruni exhibit no preference between P. insititia and P. persica plants based on olfactory cues (Gallinger et al 2019). Waveform D, as recorded by EPG, is 04 ± 20.75 (3.62-331.89) 180.…”

“…However, we are the first to show that P. persica (peach) is a less suitable host for plum psyllids, which is clearly demonstrated by the low number of nymphs that developed successfully on P. persica plants. This is in accordance with findings from field surveys of C. pruni feeding on different Prunus species (Carraro et al 2002;Gallinger et al 2019;Mergenthaler et al 2017). The measurement of abundance of C. pruni was monitored in these field surveys under the same conditions as in current study: non-grafted P. insititia rootstocks were compared with grafted P. persica scions on other rootstocks as this is common agricultural practice in fruit growing.…”

“…It was shown previously that the plum psyllid, C. pruni, prefers P. insititia plants over P. persica plants in field (Gallinger et al 2019). Our current results suggest that avoidance of P. persica appears to be beneficial to C. pruni, given that nymphs feeding on P. persica exhibited prolonged developmental time and reduced developmental success than observed on P. insititia.…”

“…P. prunorum'-infected plants. The importance of volatile organic compounds released by plants on C. pruni host preference and the importance of phloem chemistry on C. pruni development has been addressed previously (Gallinger et al 2019, Gallinger andGross 2018). Thus, the objective of the present research was to investigate the importance of gustatory cues on the host plant choice of C. pruni using two Prunus species that exhibit different degrees of sensitivity to ESFY phytoplasma infection.…”

Phytoplasmas are specialized small bacteria restricted to the phloem tissue and spread by hemipterans feeding on plant sieve tube elements. As for many other plant pathogens, it is known that phytoplasmas alter the chemistry of their hosts. Most research on phytoplasma-plant interactions focused on the induction of plant volatiles and phytohormones. Little is known about the influence of phytoplasma infections on the nutritional composition of phloem and consequences on vector behavior and development. The plum psyllid Cacopsylla pruni transmits 'Candidatus Phytoplasma prunorum', the causing agent of European Stone Fruit Yellows (ESFY). While several Prunus species are susceptible for psyllid feeding, they show different responses to the pathogen. We studied the possible modulation of plant-insect interactions by bacteria-induced changes in phloem sap chemistry. Therefore, we sampled phloem sap from phytoplasma-infected and non-infected Prunus persica and Prunus insititia plants, which differ in their susceptibility to ESFY and psyllid feeding. Furthermore, the feeding behavior and development of C. pruni nymphs was compared on infected and non-infected P. persica and P. insititia plants. Phytoplasma infection did not affect phloem consumption by C. pruni nymphs nor their development time. In contrast, the study revealed significant differences between P. insititia and P. persica in terms of both phloem chemistry and feeding behavior of C. pruni nymphs. Phloem feeding phases were four times longer on P. insititia than on P. persica, resulting in a decreased development time and higher mortality of vector insects on P. persica plants. These findings explain the low infestation rates of peach cultivars with plum psyllids commonly found in field surveys.

“…When insects locate and select potential host plants, volatile secondary metabolites emitted by plants can function as longdistance cues (Allmann et al 2013;Dahlin et al 2014;Liu et al 2020). For example, plum psyllid (Cacopsylla pruni) can use plant volatiles to locate their favorable food resources from a distance (Gallinger et al 2019). When insects come into contact with plants, nutritive and defensive metabolites can determine host plant suitability and subsequently affect their survival, growth, and reproduction (Gonçalves-Alvim et al 2004;Michael 2018;Brzozowski et al 2020).…”

Herbivores use plant chemicals for host-plant selection to maximize their own and/or offspring performance. Since host plants that are optimal for mother and offspring are often different and spatially/temporally separated, how plant chemicals affect trade-offs between adult preference and larval performance remains unclear. We found that adults of the rice water weevil (Lissorhoptrus oryzophilus), one of the most important pests on rice in the world, preferred volatiles from barnyard grass over rice, tended to feed and oviposit on barnyard grass compared with rice. In contrast, larvae performed better on rice roots than on barnyard grass roots. Chemical analysis further show that rice roots had higher nitrogen and soluble sugar but lower lignin and cellhouse contents than barnyard grass. Together, these results suggest that violate, nutritive and defensive chemicals could jointly determine trade-offs of the adult preference and larval performance on these two hosts. As developing chemical-based technology is one of the main approaches for control of pest insects, our findings may also contribute to the future efforts for management of the rice water weevil.
