Anoplophora glabripennis: Host choice, oviposition and performance of new hatched larvae on ‘resistant’ poplar species

Abstract

Most western regions of China are arid or semi-arid. To reduce encroachment by sandstorms in these areas, tens of thousands of forest belts have been established since the 1970s. The majority of these forests are comprised of different varieties or clones of poplar which are tall, fast-growing and resistant to environmental stress (Lv et al., 2000). To date, poplar is still the first choice when planting

The attractive host volatiles can enhance oviposition of Anoplophora glabripennis on a non‐host tree

“…Moreover, our result prompts a new question, i.e., should we plant lure trees near relatively resistant trees (or non-host tree)? Different tree species exhibit different levels of resistance to ALB, 8,9,44 and some host tree species have been recommended for use as lure trees to be planted in mixed forests of relatively highly resistant poplar. [45][46][47] In this scenario, they might encourage ALB oviposition on relatively resistant poplars, then some ALB individuals might develop the counter-defenses ability and finally break the defense system of these resistant poplars.…”

“…Recent studies have shown that Populus deltoides 'Shalinyang' (PdS), which can grow in north-western China, is attractive to ALB adults for oviposition but that the resulting offspring do not survive subsequent development. 8,9 This resistant variety has proved to be promising for regulating ALB populations. 8,9 Volatiles emitted by host plants can mediate interspecific interactions between plants and insects.…”

Insects recognize host plants by identifying specific compounds or ratios of compounds that are prevalent at a distance from the host.…”

“…pyramidalis) were also oviposited on by ALB. [7][8][9] The objective of the current study was to identify the volatiles released from PdS, that are used by ALB adults to search for and recognize hosts and use as signals to produce offspring; and then to determine the influence of attractive compounds from PdS on oviposition behavior of ALB. The results will inform development of mixed-species forests resistant to ALB infestation, in which attractive PdS individuals (on which larvae cannot develop) may influence the oviposition behavior of ALB.…”

“…However, most poplar species are hosts of ALB, so choosing the most resistant poplar species is very important. Recent studies have shown that Populus deltoides ‘Shalinyang’ (PdS), which can grow in north‐western China, is attractive to ALB adults for oviposition but that the resulting offspring do not survive subsequent development 8,9 . This resistant variety has proved to be promising for regulating ALB populations 8,9 …”
