“…Our results support earlier literature that H. axyridis prefers to the olfactory cues of other plant flowers, such as sunflower (Helianthus annuus L.) (Dufour 2000). Adedipe and Park (2010) found that H. axyridis adults significantly preferred sunflower and dill (Anethum graveolens L.) among 10 potential companion plants tested in an olfactory preference test. Jones and Gillett (2005) found that sunflower and nearby crop vegetation (within 1 m of sunflower) also attracted other arthropod predators, parasitic wasps, and some important pollinators.…”

The multicolored Asian lady beetle, Harmonia axyridis (Coleoptera: Coccinellidae), is a common generalist predator in China and is occasionally found gathering on the Chinese pagoda tree, Sophora japonica, in summer. In a field investigation, we found that H. axyridis adults preferred S. japonica during its flowering period even though their optimal prey (aphid) is absent at this time. In addition, male and female adults were attracted to S. japonica flowers to a similar extent in a Y-tube olfactometer assay. Using coupled gas chromatography-electroantennogram detection (GC-EAD), we identified a flower odor component (nonanal) that elicited a significant electrophysiological response in H. axyridis. Electroantennogram (EAG) dose-dependent responses revealed that the amplitude of the adult beetle's EAG response increased with increasing concentration of nonanal, peaking at 10 mg mL-1. In Y-tube olfactometer behavioral tests, H. axyridis adults preferred a 10 mg mL-1 nonanal source over a 100 mg mL-1 diluent. Under field conditions, the adults were significantly attracted to both concentrations (10 and 100 mg mL-1), and high concentrations generally had greater attraction. All these results suggest that nonanal, a volatile compound of S. japonica flowers, greatly attracts H. axyridis adults. This study provides a basis for the development of synthetic attractants of H. axyridis, with the potential to promote biocontrol services of this generalist predator in the native area (e.g., China) and to suppress its population by mass trapping in its invasive areas.

“…These effects have largely been extrapolated from empirical experiments using companion plant extracts or essential oils (Hori, ; Pavela, ; Halbert et al ., ) but scarcely using living plants. In addition to volatile emission under natural conditions, the presence of external and physical interactions, such as natural enemies (Landis et al ., ; Adedipe & Park, ; Biondi et al ., ) and root interactions (Collier & Finch, ; Glinwood et al ., ), respectively, could distort the interpretation of results.…”

Influence of neighbouring companion plants on the performance of aphid populations on sweet pepper plants under greenhouse conditions

1 Companion plants (CPs) may affect the performance of pests on their hosts because of their potential to emit volatile organic compounds (VOCs) and their effectiveness depends not only on the species, but also on their arrangement in the crop system. 2 The present study aimed to evaluate the effect of intercropping rosemary, lavender or basil on the performance of Myzus persicae populations on sweet pepper plants (Capsicum annum) under greenhouse conditions. 3 In a first set of experiments, sweet pepper plants were neighboured by either one or two CPs. In another set of experiments, rosemary was tested at three distances (0.5, 1.5 and 2.5 m) from the host plant. 4 The first set of experiments showed similar patterns of aphid performance (i.e. number of females and nymphs) when a sweet pepper plant was surrounded by one or two companion plants. However, aphid performance was affected more when sweet pepper plants were intercropped with rosemary compared with lavender or basil. 5 The effect of the companion plant decreased significantly with distance. Rosemary was most effective at 0.5 m, although its effectiveness decreased at 1.5 m, becoming insignificant at 2.5 m. 6 The results suggest that a CP may be effective under greenhouse conditions provided that it is located near the target plant.
