1.Conservation biological control aims to control pests by promoting wild
populations of natural enemies. One challenge is to attract and retain
efficient natural enemies in crop fields, which often are a suboptimal
environment. Towards this goal, the attract-and-reward strategy relies on
combining attractive synthetically produced herbivore-induced plant
volatiles (HIPVs) with companion plants (non-crop plants which provide
alternative resources to the targeted natural enemies). Although severely
overlooked, the spatial arrangement of HIPV dispensers and rewards inside
crop fields may strongly influence the foraging behaviour and persistence
of natural enemies and thus the success of this pest management strategy.
2.We tested the impact of two contrasting spatial arrangements of HIPV
dispensers and rewards, alternatively inside and around a block of target
apple trees, on the efficacy of the biological control of Aphis citricola
populations by the common predatory ladybird Propylea japonica in apple
orchards in northern China. We used synthetic methyl salicylate (MeSA) as
an attractant and the companion plant Calendula officinalis as a reward.
To better understand how the spatial arrangement of MeSA dispensers and
companion plants affected the attraction and foraging behaviour of adult
ladybirds, we conducted indoor experiments in a flight mill, an
olfactometer and a wind-tunnel. 3.Blocks of target trees treated with MeSA
dispensers inside and companion plants around provided the most efficient
pest control in orchards, compared with the opposite spatial arrangement.
4.The synthetic MeSA dispenser and the companion plant synergistically
attracted ladybirds in the olfactometer and enhanced their flight activity
in the flight mill. In the wind-tunnel, MeSA served as a spatial cue for
ladybirds to find nearby prey, while companion plants were sought in the
absence of prey. 5.Synthesis and applications. The present study will help
further improvements of aphid control in apple orchards through a careful
spatial arrangement of herbivore-induced plant volatiles dispensers
(HIPVs) and rewards (companion plants) in optimized attract-and-reward
strategies. Without such assessment, these strategies may be hazardous
even with well-identified targeted natural enemies. Associated lab
experiments highlight that HIPVs and companion plants interactively
influence ladybird foraging pattern, and that their spatial arrangement
can modulate the ability of such key predators to find their prey.
